Abstract

This wiper device has the following: a wiper arm (14) that swings about a rotating shaft (18); and a wiper motor (13) that produces the power to be transmitted to the rotating shaft (18). The wiper device is also provided with a power-transmission mechanism (19) that transmits power from the rotating shaft (18) to the wiper arm (14). Said power-transmission mechanism (19) is provided with the following: a linking member (19a) affixed to the rotating shaft (18); and a support shaft (19b) that supports the wiper arm (14) and is affixed to a point on the linking member (19a) offset from the rotating shaft (18). The support shaft (19b) is provided such that the coupling between the support shaft (19b) and the wiper arm (14) is located forwards of the front edge of the windshield (11). At least part of the wiper motor (13) is disposed in a region corresponding to the projection of the windshield (11). The wiper motor is thus disposed as far rearwards as possible in the vehicle with minimal increase in the number of components.

Description

technical field [0001] The present invention relates to a wiper device. The wiper device is configured to wipe the windshield of the vehicle by swinging a wiper arm disposed above the windshield by the power of a wiper motor disposed below the windshield of the vehicle. . Background technique [0002] In the prior art, the vehicle is equipped with a wiper device for wiping the attached matter on the windshield to ensure the driver's line of sight. The wiper device is configured to convert the rotational motion of the rotor of the wiper motor into the swing motion of the wiper arm. As forms for converting the rotational motion of the rotor of the wiper motor into the swinging motion of the wiper arm, there are known a direct drive type (DD) and a link type. First, a direct-acting wiper device has a worm formed on a rotor and a worm wheel meshing with the worm, and one end of a wiper arm is directly fixed to a rotating shaft serving as a rotation center of the worm wheel. S...
