ARMREST DEVICE

PROBLEM TO BE SOLVED: To provide an armrest device which allows easy adjustment of the height of an armrest without inserting a hand or a tool to a narrow part.SOLUTION: The armrest device of a construction machine includes: a cylindrical guide body fixed to a vehicle body; a cylindrical column movably inserted to the guide body and provided with an armrest on the end; and locking means for locking the column at an arbitrary position of the guide body. The locking means includes: a plurality of locking parts provided in the axial direction of the guide body at an interval; one through-hole provided on a position corresponding to the locking part of the column; a locking member which passes through the through-hole and is locked to the locking part; an operation member housed movably in the axial direction in the column, and provided with a locking operation part for locking the locking member to the locking part through the through-hole by movement in one direction, and a locking release part for releasing the locking of the locking member and the locking part by movement in the other direction; and a shaft member connected to the operation member at one end and to a holding part at the other end, and extended in the axial direction of the column so that the holding part is projected from the column.
