Abstract

An AS-side pivot holder (17), formed as a solid rod, is provided on one side in the longitudinal direction with a frame fixing part (17b) to which a frame member (24) is fixed, and on the other side in the longitudinal direction with a motor fixing part (17d) to which a gear case (28a) of a wiper motor (26) is fixed. Between the frame fixing part (17b) and the motor fixing part (17d), a support part (17c) is provided which rotatably supports an AS-side pivot shaft (15b) such that said pivot shaft extends in the shorter direction of the AS-side pivot holder (17). By this means, the wiper motor (26) can be fixed to the motor fixing part (17d) without brackets, and a compact, light-weight and bracket-less wiper device (14) can be achieved with improved layout properties and assembly properties.

Description

technical field [0001] The invention relates to a wiper device having a pivot shaft on which an arc brush arm is mounted and a motor for driving and swinging the pivot shaft. Background technique [0002] Generally, a wiper device is mounted on a vehicle such as an automobile. The wiper is configured to drive and swing an arc brush arm on which a wiper blade is connected to wipe off objects attached to the windshield, such as rainwater and dust. The wiper device is provided with a pivot shaft and a motor, the arc brush arm is installed on the pivot shaft, and the motor is used to drive and swing the pivot shaft. When an operation switch in the vehicle is operated, the motor is driven, whereby the wiper blade is swung by the pivot shaft. [0003] A wiper device with a wiper arm (for example a tandem type wiper device) has a pivot axis corresponding to the wiper arm. A link mechanism is provided between the pivot shaft and the motor, and the link mechanism converts the rota...
