Description

technical field

[0001] The present invention relates to rotating devices. Background technique

[0002] Conventionally, there is known a rotating device (motor actuator) in which a motor and a gear set that transmits the rotation of the rotating shaft of the motor are accommodated in a housing composed of opposing first housings and second housings (refer to Patent No. Literature 1). Usually, the first case and the second case are molded with resin.

[0004] However, in the rotary device disclosed in Patent Document 1, warpage due to shrinkage may occur when the first housing and the second housing are molded. When at least one of the first case and the second case constituting the case is warped, the positions of the gears held by the case and the inclination of the gears are unstable, and when the motor rotates, the case vibrates to cause a difference. Loud worry. Contents of the invention
