Disengagement-preventing mechanism and bush cutter provided with disengagement-preventing mechanism

摘要

A disengagement-preventing mechanism for a vibration isolator is interposed between an attachment sleeve portion of prime mover and an operating rod in a bush cutter. The disengagement-preventing mechanism includes an attachment sleeve portion, an attachment member which is to be inserted in and engaged with the attachment sleeve portion, and a C-shaped disengagement-preventing clip. The attachment sleeve portion is provided, at a peripheral wall thereof, with a clip-introducing slit extending in a circumferential direction of the attachment sleeve portion and with a clip-holding slit located so as to face the clip-introducing slit. The disengagement-preventing clip is adapted to be introduced from outside into the clip-introducing slit and brought into contact with an external end face of the attachment member. The clip is also adapted to be engaged, by way of the distal end portion thereof, with the clip-holding slit.
