Provided is a mechanism which uses a wire (50) to link revolve an operation pedal (12) and a following lever (32) around pins (17, 38) between a locking position and a lock releasing position respectively. In the mechanism, the following lever (32) is driven to the locking position side by a spring (33), a wire holder (13) is interposed between the operation pedal (12) and the wire (50). The wire holder (13) can approach to and separate from the pin (17) by been engaged to a long hollow (12c) of the operation pedal (12), and can revolve around the pin (17) integrally with the operation pedal (12). The right holder (11) is provided with a leading portion (18) having: concave portions (16a, 16b) contacting with the wire holder (13) while accepting a tensile force of the wire (50), to which when the operation pedal (12) is at the locking position and the lock releasing position the wire holder (13) is engaged respectively; and a convex portion (16c) the wire holder (13) rides over. |
