    摘要: A clutch includes a clutch housing, a drive-side rotation body, a driven-side rotation body, a rolling element arranged between an inner circumferential surface of the clutch housing and the driven-side rotation body, a support member, and grease. The support member holds the rolling element between the inner circumferential surface of the clutch housing and the driven-side rotation body. The grease is located between the inner circumferential surface of the clutch housing and the rolling element. The support member includes a guide arranged on a distal surface of the support member. When the grease is unevenly applied to the inner circumferential surface of the clutch housing, the guide is configured to guide the grease to be evenly applied to the inner circumferential surface of the clutch housing when inserted into the clutch housing.

    摘要: 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.

    摘要: 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.
