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