Claims

[Claims for Utility Model Registration] 1. A threaded rod is supported only for rotation freely in the hollow of a main body which has a tubular shape and has an elongated opening formed along the length direction, and the threaded rod is supported in the hollow of the main body. a female screw body connected to an output shaft of a motor fixed to an end thereof, and having a connecting portion formed on an outer periphery thereof protruding from the opening and connected to a driven member, is screwed onto the threaded rod;
An easily deformable band made of a flexible elastic material having a normally closed groove formed along the length of the threaded rod is attached to the main body so as to close the opening, and the easily deformable band is A linear reciprocating drive unit characterized in that the connecting portion of the female threaded body is made to protrude outside of the main body by elastically deforming and expanding the split groove. 2. The easily deformable band is made of a soft synthetic resin material, the easily deformable band is integrally formed between attachment bodies made of a hard synthetic resin material, and the attachment body is attached to the main body. A linear reciprocating drive unit according to claim 1, which is characterized by:
