Abstract
The invention relates to a wiper apparatus in which a pair of pivot axes are provided, one pivot axis at the central portion and the other pivot axis one side portion in the left and right direction of the window surface. In the invention, wherein the rod rush angle formed by a link arm, which rotates the pivot axes clockwise and counterclockwise, and a link rod can be made as small as possible. The second pivot axis at one side portion is disposed so that the plane, including the swinging locus, of the second link arm, that is coupled to the corresponding second pivot axis, and the axial line of the second link rod, in the lengthwise direction, are made roughly parallel to each other.
Claims5
A wiper apparatus, comprising;
- a pair of pivot axes, one of which is disposed at the lower part at a roughly central portion in the left and right direction of a curved window surface of a vehicle so as to protrude therefrom, and the other of which is disposed at the lower part at one side of said curved window surface of a vehicle so as to protrude therefrom;
- a pair of link arms, a link arm secured at the lower end of each pivot axis of the pair of pivot axes;
- a link rod for connecting the pair of link arms;
- and
- a wiper motor coupled to and interlocked with the link rod wherein a wiper arm disposed at a tip end of each of the said pivot axes are structured so that each wiper arm is caused to wipe off the window surface through reciprocation on the basis of reciprocatory swinging of the pair of link arms resulting from drive and rotation of the wiper motor and a surface, including a reciprocatory swing locus of at least one link arm, is disposed so as to become parallel to the axial line in the longitudinal direction of the link rod.
