Abstract

PURPOSE: To procure safety by providing a control lever for operating the working device of an earthwork vehicle with a lock device.
CONSTITUTION: For resetting from a released state to a locked state, a lock release means 37 is held up and a clamp member 35 which has been rotated counterclockwise is returned clokwise about a pivot pin 24. That is, the member 35 is rotated to the static position or horizontal position of a first bracket 21, that is, as far as the top end of a contact surface 23" contacts a stopper member 19. Then, with the release means 37 lowered onto a second bracket 31, an insert hole 39 of the means 37 mates with a stopper pin 33 of the bracket 31 and a control lever 5 comes to the locked state.
