A left operating tool stand (39) disposed on the left side of an operator's seat (15) in a wheel loader (1) includes a support member (32), an operating tool stand (39) rotatably disposed to the support member (32) between an operating position and a tilt-up position, and an operating tool (53) disposed at a front end side of the operating tool stand (39) to operate the wheel loader (1). The operating tool stand (39) includes a rotating member (40) that is rotatably mounted about a support pin (33) as a rotational pivot, the supporting pin (33) being disposed to the support member (32), and a cam roller (50) that is rotatably disposed to the rotating member (40) and rotates together with the rotating member (40) . A dimension (B) from a rotating center (O) of the rotating member (40) to an operating position contact part (60A1) with which the cam roller (50) comes in contact is formed to be smaller than a dimension (C) from the rotating center (O) of the rotating member (40) to a tilt-up position contact part (60B1) with which the cam roller (50) comes in contact.
