Kind Code:
B2
Abstract:
PURPOSE: To positively and accurately release torque exceeding a predetermined value and to positively actuate tire torque in the load torque-applied direction.
CONSTITUTION: There are provided a rolling bearing clutch-shaped structure 100: a hub 11 having a screw part 11b, and a first flange face 11c; a supporting shaft 21 having a screw part 21b, a second flange face 21c, and a gear 21a; a ratchet 22 in which unidirectional rotation is restricted, and friction boards 23, 24.
