Claims

[Scope of Utility Model Registration Claim] An electric reciprocating drive actuator that has a forward/reversible electric motor and a reduction gear mechanism and provides reciprocating motion to a driven body, comprising: a mechanical rotation limit defining means; The final stage gear member of the reduction gear mechanism has two cam surfaces spaced apart from each other in the circumferential direction, and the switch has a lever for connecting and disconnecting the contacts facing between the two cam surfaces. Means is provided at a position adjacent to the outer circumferential surface of the final stage gear member, and when the lever comes into contact with one cam surface, the forward rotation limit position of the final stage gear member is set, and when the lever comes into contact with the other cam surface. When the two cam surfaces are in contact with each other, the reverse rotation limit position of the final stage gear member is detected, and when the lever is located between the two cam surfaces, it is detected that the final stage gear member is in the rotation stroke. type reciprocating actuator.
