Abstract: An electric motor (1) includes a wiring member (20a, 20b), an annular inner housing (10) disposed on an inner circumferential side of a stator (11), and a wiring fixing member (2) formed around the wiring member (20a, 20b). A longitudinal hole (recessed part) (10a, 10d) which opens to one end surface and extends in an axial direction is formed in an outer circumferential edge portion of the inner housing (10), and a level difference (locking part) (12) is formed on an inner circumferential surface of the longitudinal hole. When the wiring member (20a, 20b) is inserted through the longitudinal hole (10a, 10d), the wiring fixing member (2) is locked to the level difference.

Abstract: Provided are a motor having a small number of parts and provided with waterproof performance in a low-cost method, and a positioning device and a conveyance device that are positioned and driven by the motor. The motor includes a columnar motor body that is formed with a center hole penetrating in an axial direction, and a housing for accommodating the motor body. The housing includes a cylindrical part that covers an outer peripheral surface of the motor body; a rotation output part provided on an upper side of the cylindrical part in the axial direction and fixed to rotary bodies of the motor body; and a fixed part provided on a lower side of the cylindrical part in the axial direction and fixed to fixed bodies of the motor body. The housing is sealed by a sealing mechanism at only one place of the cylindrical part in the axial direction.
