<p>In response to movement of a vehicle sensor body, a vehicle sensor lever (205A) moves. Thereby, a front end portion of the vehicle sensor lever is pressed to move a pilot arm (203). The pilot arm is movably supported by a clutch (202) capable of moving co-axially with a take-up drum. A locking gear (206) and the take-up drum are fixed integrally and co-axially so as to get engaged with the moved pilot arm for rotating the clutch. The thus rotated clutch leads the pawl (43) for preventing rotation of the take-up drum. While the take-up drum is in a locked state, a movement restricting portion (202G) regulates movement of the vehicle sensor lever.</p> |
