<p>PURPOSE:To prevent wrong operation of a lever and also prevent a stopper from deviating by providing a lever stopper which tightly fixes a lock mechanism in each operative position as well as to improve the operative performance of the lock mechanism by adopting a mechanism to improve the sliding performance of a cam mechanism provided in the lock mechanism so as to reduce operative load. CONSTITUTION:A lock mechanism R consists of a main driving member 4 provided to a base plate l, a slave driving member 8 to be removed in an axis direction by the main driving member 4, a locking member retaining cylinder 13, a locking member 15, an engagement member 22 provided to a base plate 1', and so on. A cam mechanism having excellent sliding performance is constituted of the cam surfaces 4a-4c of the main driving member 4 and a roller 8b provided to the slave driving member 8. Further, a lever stopper 5a is provided to a control lever 5, and the control lever 5 can be positioned by fitting the lever stopper 5a into a hole formed in a body cover 10.</p> |
