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.
