Rotation apparatus including motor and speed reducer

摘要

Provided is a rotation apparatus capable of suppressing an increase in axial length. A rotation apparatus 10 includes a motor 11 and a speed reducer 12, in which the speed reducer 12 includes a casing 24, an internal gear 22 that is integrated with the casing 24, an external gear (planetary gear) 20 that is internally engaged with the internal gear 22, and a (first) carrier body 34 that is arranged in an axial side portion of the external gear 20, the motor 11 and the speed reducer 12 are connected with each other via an adapter 50, the adapter 50 has a motor-fixed surface 51 that is fixed to the motor 11, a carrier-fixed surface 52 that is fixed to the carrier body 34, and an externally fixed surface 53 that is not parallel with the carrier-fixed surface 52 and is fixed to an installation floor 62 which is an external member, a material tray 68 that is a driven member is connected to the casing 24, the material tray 68, the speed reducer 12, and the externally fixed surface 53 are overlapped with each other when viewed from a radial direction of the speed reducer 12, and the material tray 68 is rotated within a range of 180 degrees.
