Abstract
A lock mechanism ( ) is constituted by a slide plate ( ) with a slot ( ) and a notched groove ( ), and a lock pin ( ) which is provided on the side of a console ( ). Through the slot ( ), the slide plate ( ) is slidably supported on a couple of support projections ( ) which are provided on the side of an operator's seat ( ). By engaging the notched groove ( ) with the lock pin ( ), the console ( ) is locked in an operating position. When an entrance gating lever ( ) is manipulated by an operator, the slide plate ( ) is pulled by a push-pull cable ( ) to slide in a rearward direction against the action of a tension spring ( ). Whereupon, the notched groove ( ) is disengaged from the lock pin ( ), and the console ( ) is swung back into an upturned position by the action of a gas spring ( ).
