Claims

[Scope of utility model registration request]

A reciprocating member that performs linear motion; and an intermediate member rotatably connected to one end of the reciprocating member, the intermediate member having a circular external tooth row spaced apart from the rotatable connecting portion in the axial direction. A member, a fixed internal gear meshing with the external tooth row of the intermediate member, an arm member having one end rotatably connected to the rotating shaft of the intermediate member, and a rotating shaft fixed to the other end of the arm member. The rotatable connecting portion of the reciprocating member and the intermediate member is axially aligned with the meshing point of the external teeth of the intermediate member and the fixed internal gear, and the center of rotation of the intermediate member is aligned with the meshing point of the external tooth of the intermediate member and the fixed internal gear. A linear/rotary motion conversion mechanism characterized by being aligned with the center of rotation of the shaft.
