It has book protrusions (one protrusion 1a and the other protrusion 1b). The operating means 1 is capable of one rotating operation α and the other rotating operation β about the axis L, and the one rotating operation α enables the vehicle to move forward, and the other rotating operation β moves the vehicle. Retractable.

More specifically, the protrusions 1a on one side and the protrusions 1b on the other side are protrudingly formed with a desired distance in the circumferential direction of the operating means 1, so that the driver's hand gripping the grip G One rotation operation α is enabled by applying a finger (for example, a thumb) to one protrusion 1a and pushing it forward, and the driver can press the finger (for example, index finger) of the hand that holds the grip G. The other rotation operation β is made possible by applying the other protrusion 1b and pulling it rearward.

Further, the lock means 2 is attached to a predetermined portion of the operation means 1 according to this embodiment. The lock means 2 permits one rotation operation α while restricting the other rotation operation β, and can arbitrarily release the restriction on the other rotation operation β. Independent operation (slide operation in the direction of the arrow in FIG. 2) is possible. That is, the lock means 2 is configured to be in a lock position that restricts the other rotation operation β in a normal state, and to be in an unlock position that allows the other rotation operation β by a slide operation.

More specifically, as shown in FIG. 9, the lock means 2 has an operation portion 2a and a projection portion 2b integrally formed, and a pin p and a spring s1 are attached to predetermined portions. The operating portion 2a is made up of a portion that can be operated from a locked position to an unlocked position by a driver's sliding operation of the lock means 2 by placing a finger thereon. It consists of a convex portion on which a wall surface 2bb is formed on each side.

When the locking means 2 is assembled to the operating means 1, the operating portion 2a faces the outside as shown in FIG. Further, when the lock means 2 is assembled to the operation means 1, as shown in FIG. 7, the pin p is inserted into the long hole m formed in the operation means 1, and the lock means 2 can be guided in the operation direction. , and the locking means 2 is held at the locking position by the biasing force of the spring s1.

On the other hand, as shown in FIG. 8, the case C is integrally formed with a projection Ca having a wall surface Ca1 on one side and an inclined surface Ca2 on the other side. 3, the projecting portion Ca of the case C and the projecting portion 2b of the locking means 2 face each other in the operating direction of the operating means 1, as shown in FIG. As a result, when the lock means 2 is in the lock position (non-operating state), the wall surface Ca1 of the protrusion Ca and the wall surface 2bb of the protrusion 2b come into contact with each other to restrict the other rotation operation β of the operation means 1. can. When the lock means 2 is in the lock position, when the operation means 1 is rotated in one direction α, the protrusion Ca of the case C and the protrusion 2b of the lock means 2 do not interfere with each other. will be allowed.

Here, when the lock means 2 is slid from the lock position to the unlock position, the protrusion 2b of the lock means 2 is separated from the protrusion Ca of the case C. Interference between the portion Ca and the projecting portion 2b is avoided, and the rotation operation β of the other is permitted. Further, after the lock means 2 is slid to the unlock position and the other rotation operation β is performed, the lock means 2 returns to the lock position by the biasing force of the spring s1 in the process of returning the operation means 1 to the initial position. Even if the slanted surface Ca2 of the protrusion Ca and the slanted surface 2ba of the protrusion 2b interfere with each other, the locking means 2 escapes in the slide operation direction against the biasing force of the spring s1. It is made movable to a position.

The interlocking member 3 is accommodated in the case member 4 and can be rotated in accordance with the rotating operation α on one side and the rotating operation β on the other side of the operating means 1.

The rotation angle detection means 10 (detection means) is composed of a magnetic sensor capable of detecting the rotation direction and rotation angle of the rotating member 8 by detecting the magnetic change of the magnet 9. As shown in FIG. , a predetermined electric circuit is formed on a printed substrate 11 . When one rotation operation α or the other rotation operation β is performed on the operation means 1, the interlocking member 3 and the rotation member 8 rotate according to the rotation direction and the rotation angle. can be detected by the rotation angle detection means 10 . As a result, the rotation direction and the rotation operation angle of the operation means 1 can be detected based on the detection value detected by the rotation angle detection means 10, and the vehicle can be driven (forward or backward).

According to the present embodiment, the operation means 1 is capable of one rotation operation α and the other rotation operation β. can be reversed, the driver can be made to reliably recognize the accelerator operation when the vehicle is moving forward and the accelerator operation when reversing, and erroneous operation can be prevented. Further, the operating means 1 according to the present embodiment has at least two protrusions (one protrusion 1a and the other protrusion 1b), and by pressing one protrusion 1a forward, Rotating operation α on one side is enabled, and rotating operation β on the other side is enabled by pulling the protrusion 1b toward the rear. When moving forward, it is operated forward, and when retreating, it is operated backward), and operability can be improved.

In spite of this, it is possible to prevent the operation means 1 from being erroneously rotated β in the other direction, thereby improving safety. Further, when the operation means 1 is rotated in one direction α and rotated in the other direction β, the common return spring 5 is provided to urge the operation means 1 toward the initial position. The number of parts can be reduced as compared with the one provided with both the return spring and the return spring for the other rotating operation. By using the common return spring 5, it is possible to easily equalize the operating force required for one rotation operation α during forward movement and the operation force required for the other rotation operation β during backward movement.

Further, since the resistance means 6 is provided which can generate frictional resistance in accordance with the rotation operation α on one side and the rotation operation β on the other side of the operation means 1, the operability of both the rotation operation α on one side and the rotation operation β on the other side is provided. can be improved.
