Abstract

It is an object to secure a state where an operator easily reaches various operating means with a hand, and to reliably maintain an original function of an arm rest (to put the hand on the arm for rest). A working vehicle is configured such that speed of power from an engine provided in a traveling machine body is changed by a hydraulic continuously variable transmission, and the power is transmitted to a traveling unit and a working unit. An arm rest on which the operator's arm and hand are put is placed on a side of a cockpit in the traveling machine body. A main transmission lever which changes traveling speed by the traveling unit is arranged on a front end of the arm rest on the side of the cockpit. An elevating dial which hoists and lowers the working unit is arranged on a side surface of the arm rest on the opposite side from the cockpit.

First claim

The invention claimed is:

1. A working vehicle in which speed of power from an engine provided in a traveling machine body is changed by a hydraulic continuously variable transmission and transmitted to a traveling unit and a working unit, wherein, the working vehicle comprising: an arm rest on which an arm and a hand of an operator are put is placed lateral to a cockpit in the traveling machine body, wherein
a main transmission lever for changing traveling speed by the traveling unit is arranged on a front end of the arm rest close to the cockpit, and an elevating dial for hoisting and lowering the working unit is arranged on a side surface of the arm rest on an opposite side from the cockpit.

2. The working vehicle according to claim 1 , wherein the main transmission lever projects from the front end of the arm rest on the side of the cockpit, and a front surface of the arm rest is formed into a curved surface corresponding to a turning locus of the main transmission lever.

3. The working vehicle according to claim 1 , wherein the elevating dial is fitted to a side surface of the arm rest such that an upper end of the elevating dial is located lower than an upper surface of the arm rest,
a side notch for operating a dial is provided in the side surface of the arm rest above an installation region of the elevating dial, an operating projection is provided above the elevating dial, and
front and rear step portions of the side notch are brought into abutment against the operating projection, thereby configuring the step portions as a rotation-restricting portion which restricts rotation of the elevating dial.

4. The working vehicle according to claim 1 , wherein a rear portion of the arm rest is parallel to the cockpit, and a front portion of the arm rest is separated from the cockpit toward a front end.

5. The working vehicle according to claim 1 , wherein arranged on the upper surface of the arm rest at a position behind the main transmission lever and on the side of the cockpit are a setting dial for setting a value of maximum speed of the traveling speed or a maximum rotation number of the engine, and a selecting switch for selecting whether the value set by the setting dial is the maximum speed of the traveling speed and the maximum rotation number of the engine.
