<p>A pilot lever includes: a sleeve portion configured to be rotatably fitted on a mounting boss erected on a clutch rotatably arranged coaxially with a take-up drum; and an engagement claw portion projecting outward from an outer circumferential surface of the sleeve portion so as to face a locking gear attached integrally and coaxially with the take-up drum, and configured to engage with the locking gear. In case of an emergency, the engagement claw portion engages with one locking gear tooth formed on an outer circumference portion of the locking gear. The engagement claw portion is then elastically deformable toward the sleeve portion when pushed by the one locking gear tooth under the engaged state. If the engagement claw portion and the one locking gear tooth are disengaged, the elastic deformation of the engagement claw portion is released.</p> |
