Abstract

PURPOSE: To prevent abrasion and noises by employing a contact-releasing member so as for a pawl not to contact with a ratchet when a rotary body and a roatary wheel body rotate relatively in the direction not to engage the ratchet with the pawl in the captioned device of an autobicycle.
CONSTITUTION: The main body 12 of the one-way clutch consists of a boss one-way complete 34 as the rotary body and of a sleeve 35 as the rotary wheel body. In addition, each pawl 37 is actuated in the direction of engagement with the ratchet 36 by the tensile strength of a pawl spring 38. The contact-releasing member 33 is formed of a round plate 39, and the pawl 37 is devised to fall in the direction wherein it does not contact with the ratchet by means of an engaging hole 40 when the plate 39 rotates in the direction A to the complete 34. By this constitution, offensive noises caused by tapping of te tip of the pawl 37 by the ratchet 36 are prevented.
