Abstract: A motor includes: a rotating shaft; a motor portion; a circuit board; a case having a circuit housing recess portion for housing the circuit board; and a cover made of a synthetic resin and sealing the opening portion of the circuit housing recess portion. The cover has an outer circumference rib and an inside rib. The outer circumference rib is located on the outer circumferential side from the opening end surface of the circuit housing recess portion and projects from the outer circumferential edge of the cover toward the front surface side of the cover and the rear surface side of the cover. The inside rib is located inside from the opening end surface and projects at least either on the front surface side of the cover or on the rear surface side of the cover.

Abstract: A speed reducer including: a first gear; an eccentric shaft joined to the first gear, the eccentric shaft has first and second supporting portions offset in a rotation radial direction with respect to a first gear rotation shaft; a fixed gear at an eccentric shaft radial direction outer side, and whose rotation is restricted; a transmitting gear supported at the first supporting portion and meshes with the fixed gear, and the transmitting gear revolves around the first gear rotation shaft and rotates around its own axis; an outputting portion rotating due to the transmitting gear revolving and rotating around its own axis; and a locking gear supported at the second supporting portion and meshes with the fixed gear, and the locking gear revolves around the first gear rotation shaft and rotates around its own axis, and rotation of the outputting portion is restricted.

Abstract: A clutch includes a roller arranged between a clutch housing and a driven side rotating body. The roller is rotated about a rotation axis of a drive side rotating body together with the drive side rotating body when the drive side rotating body is rotationally driven. The roller hinders rotation of the driven side rotating body by being sandwiched between the clutch housing and the driven side rotating body when the drive side rotating body is not rotationally driven. The support member sandwiches the roller between the clutch housing and the driven side rotating body. The support member rotates about the rotation axis of the drive side rotating body together with the drive side rotating body. The grease is arranged between the clutch housing and the roller. The support member restricts rotation of the roller about a central axis of the roller.

Abstract: A clutch is configured, when a driving-side rotor is in a non-driven-rotated state, to prevent rotation of a driven-side rotor by setting a rolling element in a lock state in which the rolling element is held by a control surface and a collar. The clutch is configured so that when the driving-side rotor is driven and rotated in the lock state, the driving-side rotor pushes the rolling element via two circumferential holders in a rotation direction to release the rolling element from the lock state. Each of the two circumferential holders includes a guide portion configured to guide the rolling element toward a radially inner side of the collar when the rolling element is released from the lock state.

Abstract: This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.
