[Problem] To provide a fuel-cell-stack manufacturing method capable of increasing the load that a raised piece of a deformation absorption member can receive from the separator unit. [Solution] The deformation absorption member 20 used in the fuel-cell-stack 1 manufacturing method is disposed between an anode side separator 11 and a cathode side separator 12, and comprises a thin-board-like base material 21, and a plurality of raised pieces 22 that are provided raised from one surface 21a of the base material in a grid pattern. In the arrangement step, an extension portion (the free end portion 22b) extended from the proximal end (the fixed end portion 22a) of the raised piece provided on one surface of the base material is disposed so as to be abutted to the cathode side separator or the anode side separator. The setting step sets the interval between the anode side separator and the cathode side separator along the lamination direction X so that the deformation of the raised piece exceeds an elastic deformation region and enters a plastic deformation region, and is also in a region in which the proximal end that is moved due to the deformation will not come in contact with the cathode side separator or the anode side separator.

A stabilizer link and a production method therefor, which can obtain desired pull-out strength even when a reinforced resin is used for a fixing portion of a ball seat, are provided. In the formation of the subassembly 100A, the space S is formed between the bottom portion side of the side surface portion of the main body portion 201 of the ball seat 200 and the bottom portion side of the inner surface of the housing 300. The die 600 is provided to the outer surface of the bottom portion side of the housing 300 in the subassembly 100A, and the cavity C is thereby formed. Injection molding is performed such that the reinforced resin R is injected into the cavity C and the space S. The fixing portion 202 shown in Fig. 3 is formed at the bottom portion side of the side surface portion of the main body portion 201 by the injection molding. In this case, the fixing protrusion stripe portion 231, which is fitted to the fixing groove portion 221 of the main body portion201, is formed at the fixing portion 202. The projection portion 232 projecting from the hole portion 320 of the housing to an external portion is formed at the bottom portion of the fixing portion 202, and the projection portion 232 is formed to have the shape engaging with the outer surface of the bottom portion of the housing 300.

The ball joint reliably prevents the ball seat (13) from being dislodged from the housing (11) and reliably positions the ball seat (13) vertically and radially with respect to the housing (11).
A stabilizer device 1 includes a bar 100 having a portion 10a to be mounted to a vehicle body. A resin ring 40 is integrally formed to the bar 100 by a direct injection method, and a bush 30 made of rubber is provided around the periphery of the resin ring 40. The bush 30 is fixed to a member 50 of the vehicle body side by a bracket 20. Since the contact area of the resin ring 40 to the bar 100 is secured by using the axial direction length of the bush 30, the movement strength of the bush 30 in the axial direction can be improved even when there is size restriction. In the fixing construction of the stabilizer device, the movement of the bush to the bar can be sufficiently prevented even when the size restriction is severe.

A curved portion, which has a curved cross section, is formed at the recess of the pad. The curved portion has a contact portion which contacts the tension surface of the leaf spring, which is disposed so as to face the curved portion, in an initial condition. The curved portion has a thickness which is reduced from the contact portion to an end portion of the curved portion, thereby being spaced from the tension surface of the leaf spring. In the pad, the height of the curved portion of the recess is set such that contact of the tension surface of the leaf spring and the corner portion of the end portion of the curved portion can be avoided when the stroke length of the end portion of the leaf spring is at maximum. Thus, the tension surface of the leaf spring is not worn by the corner portion of the end portion of the curved portion. As a result, breakage of the leaf spring, which may be caused by wear, can be prevented.

An object is to provide a coil antenna that is adaptable to a thin figure, and that appropriately makes the ratio of self-inductance to mutual inductance further large, so as to achieve a comparatively small mutual inductance that results in small mutual interaction even when overlapped. Without using a component such as a chip coil, a winding pattern (14) is formed with a wire (16) with which a main wiring pattern (12) is formed. This enables to deal with the flexibility by realizing a thin product using a coil antenna (10). Further, the wiring pattern is designed such that the winding pattern (14) is provided and distributed to the main wiring pattern (12) forming a loop, and is formed with the wire (16) so as to have a wound shape small enough compared with the main wiring pattern (12). In this way, the ratio of the self-inductance to the mutual inductance is appropriately made further large, so that the mutual inductance is made comparatively small.
