Abstract
A vehicle wiper device includes a wiper arm, a drive source, a drive shaft that is pivoted by the drive source, and a wiper arm urging member. The wiper arm urging member includes a swing member, an inclination member, a rod, and a compression spring. The inclination member includes a wiper fixing portion and a drawing portion. The rod includes a basal end supported by the drawing portion. A first end of the compression spring is supported by the swing member and the second end applies an urging force to a distal end of the rod. The compression spring acts to draw the drawing portion and urge a distal end of the wiper arm toward a wiped surface.
Claims15
A vehicle wiper device comprising:
- a wiper arm;
- a drive source;
- a drive shaft that is pivoted back and forth by the drive source and has a pivot axis;
- and
- a wiper arm urging member that includes
- a swing member arranged to be pivotal integrally with the drive shaft,
- an inclination member supported by the swing member and inclinable about an inclination axis, wherein the inclination axis and the pivot axis have an intersecting or skew positional relationship, and the inclination member includes a wiper fixing portion, to which the wiper arm is fixed, and a drawing portion that extends toward a distal side of the wiper arm relative to the inclination axis,
- a rod including a basal end supported by the drawing portion pivotally about a parallel axis, wherein the parallel axis is parallel to the inclination axis, and
- a compression spring including a first end and a second end located at a side opposite to the first end, wherein the first end is supported by the swing member and the second end applies an urging force to a distal end of the rod so that the compression spring acts to draw the drawing portion and urge a distal end of the wiper arm toward a wiped surface.
