Abstract

The invention relates to a rotary device. The rotary device (1) according to an embodiment of the present invention is provided with: a casing (2) including a first case (21) and a second case (22) opposed to each other; a motor (3) housed in the casing (2); and a gear (5) that transmits the rotation of the motor (3) to the outside and that is housed in the casing (2). A tubular protrusion part (28) having a first through-hole (281) is formed in the first case (21), and a second through-hole (282) into which the protrusion part (28) is fitted is provided in the second case (22).

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. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-5512 [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 [0005] ...
