A motor includes a motor body, a pin, a core, and an input cam. The motor body includes a housing and an output shaft. The pin is arranged in the output shaft to extend in a direction orthogonal to a rotation axis of the output shaft. The core is pivotally supported by the pin and rotates coaxially with the output shaft. The input cam is annular and surrounds an outer circumference of the core. The input cam rotates integrally with the core. An end surface of the core closer to the housing includes a first deviated surface. The core includes an insertion portion into which the pin is inserted. When a center axis of the core is coaxial to the rotation axis of the output shaft, the first deviated surface is located at a position farther from the housing than the insertion portion.
