Title:
DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/001988
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a drive device provided with a nut rotation prevention mechanism which more effectively prevents the loosening of a nut which restricts the axial movement of a main bearing.
A securing nut (27) which restricts the axial movement of a main bearing (26b) is mounted to the outer periphery of a case (2). A pin hole (2b) into which a pin (28) engaging with the securing nut (27) is inserted is formed in the speed reducer (5)-side end of the case (2). Protrusions (28a) are provided on the outer peripheral surface of the pin (28). The protrusions (28a) secure the pin (28) in the circumferential direction of the pin hole (2b) relative to the pin hole (2b) and prevent the securing nut (27) from rotating.
