Abstract

A wiper arm includes a spring for applying a biasing force to the rotation of an arm main body with respect to an arm head and enables the thickness of the wiper arm to be thinner while ensuring the suitable biasing force. The wiper arm also includes a coil spring and a spring plate. The arm main body includes a hinge block rotatably connected to the arm head through a hinge pin and a shaft section extending from the hinge block. The spring plate includes a front end wall including an insertion hole into which the shaft section is inserted and leg sections rotatably attached to the arm head through a roller pin. The coil spring is disposed to be coaxial with the shaft section and is held to be sandwiched between the front end surface of the hinge block and the front end wall of the spring plate.
