Claims

[Scope of utility model registration request]

In a headlamp wiper mechanism, a wiper blade for wiping a front lens of a headlamp is attached to a wiper shaft via a wiper arm, and a drive means for reciprocating the wiper shaft is provided. A wave motor is provided, and the rotor of each of the plurality of surface wave motors is attached to the wiper shaft, and the rotors other than one of the plurality of rotors are attached to the axis of the wiper shaft. A wiper mechanism for a headlamp, characterized in that it allows sliding in the center direction and locks relative rotation around the axis.
