Abstract
A head of an output shaft of a linear actuator is modified so as to absorb vibrations that may be transmitted between the output shaft and a moving object. A linear actuator has an output shaft with a leading end to which a head is fixed. The head has an O-ring that is fitted thereto, and a part of the O-ring outwardly projects from the head. The O-ring is made of rubber that is softer than the material of the head. The head is contained in a containing space in an attachment, and in this condition, the O-ring contacts an inner circumferential surface of the containing space by deforming.
Claims5
A linear actuator comprising:
- an output shaft with a leading end;
- a linear driving device for linearly moving the output shaft in an axial direction of the output shaft;
- a head provided to the leading end of the output shaft;
- and
- an elastic member provided to the head and projecting from the head,
- wherein the elastic member is an O-ring that is softer than the head, the head has a circumferential surface provided with a circumferential groove, and the O-ring is fitted into the circumferential groove.
