OPERATION SEAT DEVICE OF CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To stabilize a front side position of an armrest; and to easily and accurately adjust an inclination of the armrest to an operation lever.

SOLUTION: The armrest 20 is constituted so that a rear side position extending backward from a rocking fulcrum O is inclined at an optional angle in the vertical direction with a front side position becoming the wrist side at operator's arm placing time as the rocking fulcrum O. Thus, the armrest 20 can support a wrist in a position for easily gripping the operation lever 16 by the front side position, and can properly adjust a height position of an arm in the rear side position. The inclination can be easily and accurately adjusted with the front side position of the armrest 20 as the rocking fulcrum.
