Abstract

A traveling vehicle includes: a body; a steering wheel that is attached to the body and rotates around a rotating shaft; and a forward-reverse switching lever that switches between a forward position, a neutral position, and a reverse position. The forward-reverse switching lever includes: a lever main body that is pulled up at the neutral position and swings forward or rearward in a pulled-up state; and a grip mounted to an upper portion of the lever main body, the grip includes: a base portion including an upper face; and a protruding portion protruding downward from the base portion, and the protruding portion includes: a distal face that is opposite a rotating-shaft side of the protruding portion; a first side face; and a second side face.

First claim

The invention claimed is:

1. A traveling vehicle comprising:
a body;
a steering wheel that is attached to the body and rotates around a rotating shaft; and
a forward-reverse switching lever that switches between a forward position, a neutral position, and a reverse position; wherein
the forward-reverse switching lever comprises:
a lever main body that is pulled up at the neutral position and swings forward or rearward in a pulled-up state; and
a grip mounted to an upper portion of the lever main body,

the grip comprises:
a base portion comprising an upper face; and
a protruding portion protruding downward from the base portion,

the protruding portion comprises:
a distal face that is opposite a rotating-shaft side of the protruding portion;
a first side face that is on a first side in a swinging direction of the forward-reverse switching lever and continues to the distal face; and
a second side face that is on a second side in the swinging direction and continues to the distal face, the first side face and the second side face gradually approaching each other as the first side face and the second side face go to a lower side,

the first side face comprises a first curved portion that is recessed toward a second-side-face side as the first curved portion moves downward,
the second side face comprises a second curved portion that is recessed toward a first-side-face side as the second curved portion moves downward,
the first side face comprises a first proximal portion positioned on the rotating-shaft side and a first distal portion positioned on another side opposite the rotating shaft,
the second side face comprises a second proximal portion positioned on the rotating-shaft side and a second distal portion positioned on another side opposite the rotating shaft,
the first curved portion has a first curvature radius smaller than a second curvature radius, the first curvature radius is of an intermediate portion between the first proximal portion and the first distal portion, and the second curvature radius is of the first distal portion, and
the second curved portion has a third curvature radius smaller than a fourth curvature radius, the third curvature radius is of an intermediate portion between the second proximal portion and the second distal portion, and the fourth curvature radius is of the second distal portion.

2. The traveling vehicle of claim 1 , wherein the protruding portion extends over an entire length in a depth direction of the grip, the depth direction being along a direction from one side of the protruding portion opposite the rotating-shaft side to the rotating-shaft side.

3. The traveling vehicle of claim 1 , wherein
the first side face has a first constricted portion that is recessed toward a second-side-face side viewed from a bottom side, and
the second side face has a second constricted portion that is recessed toward a first-side-face side viewed from the bottom side.

4. The traveling vehicle of claim 1 , wherein
the grip comprises an engaging portion between the first side face and the second side face, and
the engaging portion engages with the lever main body.

5. The traveling vehicle of claim 1 , further comprising:
a guide plate that regulates an operation of the lever main body, wherein
the guide plate comprises a guide groove into which one end of the lever main body is inserted.

6. The traveling vehicle of claim 1 , wherein
the first curved portion comprises a first recessed portion that is recessed from a base of the protruding portion in a diagonally upward manner and bores the base portion, and
the second curved portion comprises a second recessed portion that is recessed from a base of the protruding portion in a diagonally upward manner and bores the base portion.

7. The traveling vehicle of claim 1 , wherein
the first side face comprises a plurality of first ribs arranged in a depth direction of the grip, and
the second side face comprises a plurality of second ribs arranged in the depth direction.

8. A traveling vehicle comprising:
a body;
a steering wheel that is attached to the body and rotates around a rotating shaft; and
a forward-reverse switching lever that switches between a forward position, a neutral position, and a reverse position; wherein
the forward-reverse switching lever comprises:
a lever main body that is pulled up at the neutral position and swings forward or rearward in a pulled-up state; and
a grip mounted to an upper portion of the lever main body,

the grip comprises:
a base portion comprising an upper face; and
a protruding portion protruding downward from the base portion,

the protruding portion comprises:
a distal face that is opposite a rotating-shaft side of the protruding portion;
a first side face that is on a first side in a swinging direction of the forward-reverse switching lever and continues to the distal face; and
a second side face that is on a second side in the swinging direction and continues to the distal face, the first side face and the second side face gradually approaching each other as the first side face and the second side face go to a lower side,

the first side face comprises a first curved portion that is recessed toward a second-side-face side as the first curved portion moves downward,
the second side face comprises a second curved portion that is recessed toward a first-side-face side as the second curved portion moves downward,
the first curved portion comprises a first recessed portion that is recessed from a base of the protruding portion in a diagonally upward manner and bores the base portion, and
the second curved portion comprises a second recessed portion that is recessed from a base of the protruding portion in a diagonally upward manner and bores the base portion.

9. The traveling vehicle of claim 8 , wherein the protruding portion extends over an entire length in a depth direction of the grip, the depth direction being along a direction from one side of the protruding portion opposite the rotating-shaft side to the rotating-shaft side.

10. The traveling vehicle of claim 8 , wherein
the first side face has a first constricted portion that is recessed toward a second-side-face side viewed from a bottom side, and
the second side face has a second constricted portion that is recessed toward a first-side-face side viewed from the bottom side.

11. The traveling vehicle of claim 8 , wherein
the grip comprises an engaging portion between the first side face and the second side face, and
the engaging portion engages with the lever main body.

12. The traveling vehicle of claim 8 , further comprising:
a guide plate that regulates an operation of the lever main body, wherein
the guide plate comprises a guide groove into which one end of the lever main body is inserted.

13. The traveling vehicle of claim 8 , wherein
the first side face comprises a plurality of first ribs arranged in a depth direction of the grip, and
the second side face comprises a plurality of second ribs arranged in the depth direction.

14. A traveling vehicle comprising:
a body;
a steering wheel that is attached to the body and rotates around a rotating shaft; and
a forward-reverse switching lever that switches between a forward position, a neutral position, and a reverse position; wherein
the forward-reverse switching lever comprises:
a lever main body that is pulled up at the neutral position and swings forward or rearward in a pulled-up state; and
a grip mounted to an upper portion of the lever main body,

the grip comprises:
