<P>PROBLEM TO BE SOLVED: To provide an arm rest device of a construction machine in which a height of an arm rest can be adjusted by a simple configuration and operation while suppressing a change in a relative distance in a front-rear direction of the arm rest with respect to an operation lever. <P>SOLUTION: The arm rest device 28 is assembled in a console 24 in which an operation lever 27 that stands in a forward tilting state at a neutral position is installed. The arm rest device includes: an arm rest 30 disposed behind the operation lever 27; an arm rest mounting bracket 29 fixed to a console chassis 25; two lines of slits 41, 42 provided in the arm rest mounting bracket 29 so that the two slits vertically extend while forwardly tilting are spaced at a predetermined distance in a front-rear direction, and parallel to each other; and fastening tools 31, 32 having screw shafts 31a, 32a screwed to the arm rest 30 through the slits 41, 42 to fasten the arm rest 30 and the arm rest mounting bracket 29. <P>COPYRIGHT: (C)2012,JPO&INPIT |
