摘要

PROBLEM TO BE SOLVED: To provide a clutch having a further reduced size.

SOLUTION: The clutch 50 includes roller members 64 held between each of a driving connection part 61 provided integrally rotatable with a rotating shaft 20 and an intermediate plate 63 held in a predetermined rotation position relative to the driving connection part 61 and a driven connection part 71 provided integrally rotatable with a worm shaft 32, for connecting the rotating shaft 20 and the worm shaft 32 to each other. The crank-shaped roller members 64 each consist of a connection portion 64a, a held portion 64b arranged between each of the driving connection part 61 and the intermediate plate 63 and the driven connection part 71 in the radial direction, and an energized portion 64c. The energized portion 64c is located on the rotational center side of the driving connection part 61 beyond the held portion 64b. The energized portion 64c is energized from the radial outside to the radial inside by a second compression spring 66.
