WIPO Patent Application WO/2014/203337
Kind Code:
A1
Abstract:
Provided are: a rotation mechanism which is provided with a mechanical stopper mechanism and which is compact; and a robot. A rotation mechanism is provided with a drive shaft, a shaft body, a screw section, a set of stationary members, and a movable member. The drive shaft rotates and drives a body to be driven. The shaft body is associated with the drive shaft, and the screw section is provided to the shaft body. The set of stationary members is mounted to the screw section at a predetermined distance from each other. The movable member is mounted between the set of stationary members so as to be prevented from rotating, moves forward and backward on the screw section as the shaft body rotates, and restricts the rotation of the drive shaft by coming into contact with the stationary members.
