Vehicle wiper device

摘要

A vehicle wiper device includes a drive device, a drive shaft rotated back and forth about a first axis by the drive device, a wiper arm pivoted back and forth along a wiping surface as the drive shaft rotates back and forth, and a wiper arm biasing mechanism that biases the wiper arm toward the wiping surface. The wiper arm biasing mechanism includes a swing member, a tilting member, and a biasing member. The swing member is integrally pivotal with the drive shaft. The tilting member is supported by the swing member so as to tilt about a second axis. The tilting member includes a wiper fixing portion. The biasing member, which includes a first end supported by the swing member, and applies a biasing force to the tilting member.

1. A vehicle wiper device comprising:
a drive device; a drive shaft rotated back and forth about a first axis by the drive device; a holder member that pivotally supports the drive shaft; a wiper arm that pivots back and forth along a wiping surface as the drive shaft rotates back and forth; and a wiper arm biasing mechanism that is arranged on the drive shaft and biases the wiper arm toward the wiping surface, wherein the wiper arm biasing mechanism includes a swing member that is integrally pivotal with the drive shaft, a tilting member that is pivotally mounted on the swing member to tilt about a second axis, which intersects the first axis or is in a skew-line relationship with the first axis, wherein the tilting member includes a wiper fixing portion to which the wiper arm is fixed, and an elongated biasing member defining opposed first and second ends, the first end supported on the swing member and the second end supported by the tilting member, wherein the biasing member applies a biasing force between and to the swing member and the tilting member.
