The present disclosure exemplifies a motor attachment bracket including a plate-shaped motor mounting portion which an output shaft insertion hole through which an output shaft of a motor is inserted penetrates, and to which the motor the output shaft of which is inserted through the output shaft insertion hole is fixed. A fluid path in which a cooling fluid is circulated is formed in a metal member formed with the motor mounting portion, a motor attachment structure using the motor attachment bracket, and a substrate processing apparatus.

A stator unit included in a motor includes a base member, an armature, a circuit board, and a mold resin portion. The base member extends substantially perpendicularly to a vertically extending center axis. The armature and the circuit board are positioned above the base member. The circuit board is electrically connected to the armature. The mold resin portion covers the armature and the circuit board. In a process of forming the mold resin portion, the base member is firstly supported by a first mold.

A vehicle seat actuator includes an electric motor and a gear set that connects the drive motor to the seat and transmits the output of the motor to the vehicle seat. The drive motor and gear set are each disposed in an individual, dedicated housing component. The individual housing components are then assembled together to provide the actuator. The housing components are maintained in the assembled configuration using snap fit mechanical fasteners. Each snap-fit fastener includes a receiving portion provided on one housing component and an insertion portion provided on the other housing component. The receiving portion may be a slot formed in the gear housing that is partially obstructed by an elastic member, while insertion portion is an ear that protrudes from an outer surface of the drive motor housing and forms both a snap-fit engagement with the elastic member and a press-fit engagement with the slot.
