Abstract

Claims (29)

1. A control lever device comprising:

a control lever unit which includes an inner frame, a control lever supported by the inner frame in a manner to be movable about a fulcrum along a first direction, and a positioning roller which is attached in the inner frame and allows the control lever to be positioned at a first displacement position and a second displacement position located on a straight line by allowing an end of the control lever to pass over the positioning roller;

an outer frame which supports the control lever unit so that the control lever unit is movable in a second direction which intersects the first direction at right angles; and

a moving path control section which controls a moving path of the control lever,

wherein the control lever unit includes a lever position detection section which detects a position of the control lever in the inner frame, and

wherein the outer frame includes a unit position detection section which detects movement of the control lever unit in the outer frame.

2. The control lever device as defined in claim 1 ,

wherein the control lever unit is provided in the outer frame so that the control lever unit is movable about a fulcrum in the second direction, and is biased toward a neutral position by a neutral position biasing section.

3. The control lever device as defined in claim 1 ,

wherein two of the positioning rollers are arranged side by side, and

wherein the control lever is positioned at a neutral position which is between the first and second displacement positions by positioning the end of the control lever between the positioning rollers.

4. The control lever device as defined in claim 2 ,

wherein two of the positioning rollers are arranged side by side, and

wherein the control lever is positioned at a neutral position which is between the first and second displacement positions by positioning the end of the control lever between the positioning rollers.

5. The control lever device as defined in claim 1 ,

wherein the moving path control section is replaceable so that the moving path of the control lever changes.

6. The control lever device as defined in claim 2 ,

wherein the moving path control section is replaceable so that the moving path of the control lever changes.

7. The control lever device as defined in claim 3 ,

wherein the moving path control section is replaceable so that the moving path of the control lever changes.

8. The control lever device as defined in claim 4 ,

wherein the moving path control section is replaceable so that the moving path of the control lever changes.

9. A control lever device comprising:

a control lever unit which includes an inner frame, a control lever supported by the inner frame in a manner to be movable about a fulcrum along a first direction, and a positioning roller which is attached in the inner frame and allows the control lever to be positioned at a first displacement position and a second displacement position located on a straight line by allowing an end of the control lever to pass over the positioning roller;

an outer frame which supports the control lever unit so that the control lever unit is movable in a second direction which intersects the first direction at right angles; and

a moving path control section which controls a moving path of the control lever,

wherein the control lever unit includes a lever position detection section which detects a position of the control lever,

wherein the outer frame includes a unit position detection section which detects movement of the control lever unit, and

wherein the movement of the control lever in the second direction is detected by detecting the movement of the control lever unit in the second direction by using the unit position detection sections.
