O Utility Model Registration Claims A rotor that is rotatably supported and ring-mounted with a magnetized magnet is provided with an engaging protrusion, and the rotor is rotatable and follows a reduction gear driven by a pinion provided on the rotor. In a rotational direction regulating mechanism for a small motor in which a freely provided rotation control body is brought into contact with the engagement protrusion, a fixed member is provided with a stop portion, and the rotation control body is provided with a stop portion. 1. A rotation direction regulating mechanism for a small motor, characterized in that a regulating part is elastically disposed to abut against the abutting part, and collision noise between the abutting part and the regulating part is reduced. The brief description of the drawing should be amended as follows. "Restriction pin" in the first line of page 8 of the specification is corrected to "restriction portion."

Claims

[Scope of utility model registration request]

An engaging protrusion is formed on a rotor having a hollow shaft portion enclosing a magnetized magnet rotatably supported on a rotor shaft, and a frictional coupling member is formed on a reduction gear driven by a pinion provided on the rotor. In the rotation direction regulating mechanism for a small motor, the rotation control body is rotatably provided and is in contact with the engagement protrusion, wherein the motor case is provided with a stop portion, and the rotation control body is provided with a stop portion. 1. A rotation direction regulating mechanism for a small motor, characterized in that a regulating pin that abuts on a portion is elastically provided to reduce collision noise between the abutting portion and the regulating pin.
