| 摘要 |
The present invention relates to a torque limiter. The torque limiter comprises a container member and a shaft member which are integrated indivisible members. The container member has first and second ring-shaped parts which are welded to each other by a first ring-shaped welding part on one end of a hydraulic expansion chamber and are welded to each other by a second ring-shaped welding part on the other end of the hydraulic expansion chamber. The first and second ring-shaped parts are overlapped with each other in the axial direction of the container member by the first and second welding parts. Therefore, the present invention reduces manufacturing costs and easily secures a thickness. |
