Abstract
A torque limiter includes a first meshing portion provided at a surface of an input shaft which transmits a drive force of a drive motor, the surface intersecting with an axial direction of the input shaft, and a disc spring portion including a second meshing portion arranged facing the first meshing portion in the axial direction and which is configured to mesh with the first meshing portion. The disc spring portion is integrally rotatable with an output shaft which is provided coaxially with the input shaft and which is rotatable relative to the input shaft, and is deflected to displace the second meshing portion in a direction opposite to the first meshing portion in a case where a load equal to or greater than a set value is applied to the disc spring portion while the second meshing portion is being biased towards the first meshing portion.
