Claims

[Scope of utility model registration request]

A retainer connected to the arm head via a hinge part, a lever whose one end part is rotatably supported by the arm head, and a hook part provided on one end side is suspended from the other end part of the lever, and a tension coil that constantly urges the wiper arm toward the windshield glass surface, the wiper device having a shape memory alloy coil connected at both ends to the arm head and the lever, the shape memory alloy coil being connected at both ends to the arm head and the lever. When the vehicle speed exceeds a predetermined speed, the lever deforms as if extending and rotates with one end of the lever as a fulcrum.
A wiper device characterized in that a hook portion of a tension coil is configured to be separated from a hinge portion of an arm head and a retainer.
