Therefore, it is possible to inhibit the occurrence of defects caused by the blade wiper 50 not being able to correctly tilt relative to the surface 11a (chattering phenomenon, reversing defect, premature wear of rubber, increase in lift during high-speed travel, etc.). The present invention makes it possible to easily improve the quietness of the wiper device 10 without adding new components.

A cross-sectional shape of the pinion gear 31 can be made non-circular with the pinion main body 31b partially protruding toward the outer side of the imaginary circle VC that forms the outer shape of the helical tooth 31c. The present invention can improve the strength of the pinion gear 31 while suppressing an increase in the diameter thereof, and can improve the power transmission efficiency between the pinion gear 31 and a helical gear 32 by improving the strength of both of the gears. Accordingly, a higher speed reduction ratio can also be easily handled.
