Claims

[Scope of utility model registration request]

A shovel in which a boom supporting a bucket belt and an arm is mounted on the front part of the swivel base 1, and an operating post on which an operating lever of the bucket belt or the like is mounted is erected between the boom and the cockpit, Control valves associated with the bucket, arm, and boom are provided at the bottom of the operation post, shafts corresponding to these control valves are constructed, and these shafts are provided with connecting portions that form a pair on the left and right, so that the shafts form a pair. One of the connecting parts is connected to the yoke part of the operating lever provided on the upper part of the operating post with a detachable rod, and a reversing mechanism is interposed in the operating system so that the operating direction is reversed when the operating pattern is changed. An operating device for a shovel characterized by:
