Abstract
A wiper device includes a wiper arm and a drive section. The wiper arm has a base end portion supported by a support section provided at a vehicle, and is configured such that a wiping surface of the vehicle is wiped back and forth by a wiper blade coupled to a leading end portion of the wiper arm. The drive section is configured to displace at least a leading end portion side of the wiper arm in an up-and-down direction with respect to the wiping surface during back and forth movement of the wiper arm, irrespective of force the wiper blade receives from the wiping surface.
Claims13
A wiper device comprising:
- a wiper arm having a base end portion supported by a support section provided at a vehicle, and being configured such that a wiping surface of the vehicle is wiped back and forth by a wiper blade coupled to a leading end portion of the wiper arm;
- and
- a drive section configured to displace at least a leading end portion side of the wiper arm in an up-and-down direction with respect to the wiping surface during back and forth movement of the wiper arm, irrespective of force the wiper blade receives from the wiping surface, wherein:
- the drive section includes an actuator configured to displace at least the leading end portion side in the up-and-down direction with respect to the wiping surface;
- the wiper arm includes:
- a fixed section fixed to the support section;
- and
- a movable section including the leading end portion and supported such that the leading end portion is capable of pivoting with respect to the fixed section about a hinge shaft running in a movement direction of the wiper arm;
- the actuator is an arm actuator configured to pivot the movable section with respect to the fixed section;
- and
- a motor of the actuator is located more toward the leading end portion of the wiper arm than is the hinge shaft.
