Abstract
A swing lever is fixed to a pivot shaft to pivot the pivot shaft about a pivot axis thereof. A wiper arm is directly connected to a distal end portion of the pivot shaft and is pivoted together with the pivot shaft about the pivot axis of the pivot shaft when the pivot shaft is driven by the swing lever. The wiper arm is pivotable about a pivot axis thereof, which is generally perpendicular to or is tilted relative to the pivot axis of the pivot shaft, toward or away from a wiping surface. A coil spring is directly or indirectly connected between the wiper arm and the swing lever to exert an urging force to urge the wiper arm toward the wiping surface in a wiping operational position of the wiper arm for wiping the wiping surface.
Claims18
A wiper apparatus for wiping a wiping surface of a vehicle, comprising:
- a pivot holder that is adapted to be installed to a body of the vehicle;
- a pivot shaft that is supported by the pivot holder and is pivotable about a pivot axis thereof;
- a swing member that is fixed to the pivot shaft to drive the pivot shaft about the pivot axis;
- a wiper arm that is connected to a distal end portion of the pivot shaft, which is located on one axial side of the pivot holder and is opposite from the swing member in an axial direction of the pivot shaft, wherein the wiper arm is pivoted together with the pivot shaft about the pivot axis of the pivot shaft when the pivot shaft is driven by the swing member, and the wiper arm is pivotable about a pivot axis thereof, which is angled relative to the pivot axis of the pivot shaft, toward or away from the wiping surface;
- and
- at least one urging member that is placed at an outside of the wiper arm and has:
- one end portion, which is located on the one axial side of the pivot holder and is directly or indirectly connected to the wiper arm;
- and
- another end portion, which is located on another axial side of the pivot holder and is directly or indirectly connected to the swing member, wherein the at least one urging member exerts an urging force to urge the wiper arm toward the wiping surface in a wiping operational position of the wiper arm for wiping the wiping surface.

- and
- at least one urging member that is directly or indirectly connected between the wiper arm and the swing member to exert an urging force to urge the wiper arm toward the wiping surface in a wiping operational position of the wiper arm for wiping the wiping surface, wherein:
- the wiper arm includes:
- a base member that is directly connected to the distal end portion of the pivot shaft and is engaged with the at least one urging member;
- and
- an elongated arm member that is installed to the base member;
- the base member has a fixation shaft, which extends in a direction that is generally parallel to the pivot axis of the pivot shaft;
- and
- the arm member is installed to the fixation shaft in such a manner that a position of the arm member is adjustable about the fixation shaft.
