A handle grip 6 is rotatably provided with respect to the handle switch box 4 by a connecting means (not shown).

The handle switch box 4 is provided with a shift indicator 14 that indicates the position of a shift command to an electric transmission (not shown).

An operating portion 18 of a locking mechanism 16 for releasing the locked state of the handle grip 6 and making it rotatable is provided at the base 12 of the handle grip 6 so as to protrude and be slidable in the axial direction of the handle grip 6.

This lock mechanism 16 is located at a location where it can be operated with the thumb of the left hand while grasping the handle grip 6 with the left hand.

On the other hand, the joint surface 4 of the handle switch box 4
In the central part of a, there is a base 1 of the handle grip 6.
A mortise 4 that receives a tenon 20 protruding from the joint surface 12a of the second part and allows the tenon 20 to move freely.
2 is formed.

This mortise 42 includes a circular central receiving part 42a that receives the center part 20a of the tenon 20, and a protruding receiving part that has approximately half the inner peripheral surface of the central receiving part 42a with a slightly larger diameter and that receives the protruding part 20b. 42b. Therefore, the rotation range of the handle grip 6 is
This is regulated by the shapes of the protruding portion 20b of the tenon 20 and the protruding receiving portion 42b of the mortise 42.

Also, the joint surface 4 of the handle switch box 4
On the a side, a locking hole 44-1 which is elongated in the circumferential direction and circular locking holes 44-2 and 44-3 are formed with the same circumference so as to insert the locking rod 26 of the lock mechanism 16. It is perforated on top. The locking rod 26 fits into this locking hole 44.
By inserting the grip into the handle, rotation of the handle grip 6 is prevented. However, by forming the locking hole 44-1 into a long hole shape in the circumferential direction, it is possible to share the locking hole 44-1 between the neutral [N] and drive [D] of the shift indicator 14. Thus, the handle grip 6 can be rotated without operating the lock mechanism 16.

Further, when the locking rod 26 is inserted into the locking hole 44-2, the light emitting diode 40 is located at the second [2] position of the shift indicator 14.

Further, when the locking rod 26 is inserted into the locking hole 44-3, the light emitting diode 40 is located at the first [1] position of the shift indicator 14.

The moderation ball 34 of the moderation mechanism 28 is slightly fitted into the joint surface 4a side of the handle switch box 4, and the first and second moderation balls 34 of the moderation mechanism 28 are inserted into the shift indicator 14 at the locations (four locations in this embodiment) where the shift command position is indicated. , 3, 4 ball hole 46-1, 46
-2, 46-3, and 46-4 are drilled on the same circumference.

Further, as described above, a shift indicator 14 is provided on the outer periphery of the handle switch box 4 and on the joint surface 4a side.

This shift indicator 14 is divided into drive [D], neutral [N], second [2], and first [1] as shift range patterns.

A first cage 48-1 is formed at the drive [D] position, and a second cage 48-1 is formed at the neutral [N] position.
2. The third cage 48- is in the second [2] position.
3, and a fourth cage 48-4 is formed at the first [1] position.

The cage 48 includes first, second, third, and fourth phototransistors 50-1, 50-2, 50-3, and 50-4, which are light-receiving elements that receive visible light from the light-emitting diode 40 provided on the handle grip 6. It is set up to accommodate.

Therefore, the shift command switch section 38 is composed of a light emitting diode 40, a phototransistor 50, and a shift indicator 14.

The phototransistor 50 receives visible light from the light emitting diode 40, converts the optical signal into an electrical signal, and generates a speed change command signal to the electric transmission.
At this time, the signal from the phototransistor 50 is sent through the PNP junction type 52 and the NPN junction type 54 (see FIG. 8).

Said first, second, third, fourth cages 48-1, 48-
2, 48-3, and 48-4 are integrally covered with a protective cover 56 made of a transparent material. As a result, when the visible hole of the light emitting diode 40 is located in either cage 48, the visible light passes through the protective cover 56, allowing the driver to confirm the shift command position.

Next, the operation of this embodiment will be explained.

In a state where a gear change operation is not performed, the lock mechanism 16 provided at the base 12 of the handle grip 6 is not operated. Therefore, the locking rod 26 of the locking mechanism 16
is pressed by the lock spring 24 to lock the elongated locking hole 44- provided in the handle switch box 4.
1, the handle grip 6 cannot be rotated. However, between the neutral [N] position and the drive [D] position, the locking hole 44-
By forming the handle 1 in the shape of a long hole in the circumferential direction, the handle grip 6 can be rotated without operating the lock mechanism 16.

On the other hand, when changing gears, the locking mechanism 16 is operated with the thumb of the left hand, and the locking rod 26 is moved into the locking hole 44 against the pressing force of the lock spring 24.
When the handle grip 6 is pulled out from 1 and released from the locked state, the handle grip 6 can be rotated.

Further, when the handle grip 6 is rotated, the moderation ball 34 resists the pressing force of the moderation spring 32 and comes out of the ball hole 46-1.

Next, for example, the gear change command is set to first [1].
If you wish to do so, rotate the handle grip 6 until the locking rod 26 is inserted into the locking hole 44-3 while releasing the locked state, and then insert the locking rod 26 into the locking hole 46-3. This prevents the handle grip 6 from rotating, thereby preventing the handle grip 6 from rotating unnecessarily.

Also, at this time, the moderation ball 34 is inserted into the ball hole 46.
-4, it is possible to moderate the rotational operation of the handle grip 6 relative to the shift command position, and to provide a click feeling to the driver.

Further, the phototransistor 50-4 receives visible light from the light emitting diode 40, and as shown in FIG. becomes low, and generates a signal for shifting command to the shifting position.

As a result, the light emitting diode 40 becomes the phototransistor 50-1, 50-2, 50-3, 50-4.
When the handlebar grip 6 is located at either of the positions, the moderation mechanism 28 can moderate the rotational operation of the handle grip 6 and provide a click feeling at the shift command position.

Further, the driver can sense the matching position of the light emitting diode 40 and the phototransistor 50.

Furthermore, the driver can cover the protective cover 56 which is a transparent material.
The shift command position can be easily confirmed by the visible light from the light emitting diode 40 illuminating the shift command position. This allows the driver to concentrate on safe driving and improves safety while driving.

Furthermore, a tenon 20 formed on the joint surface 12a of the base 12 of the handle grip 6 and a tenon 20 formed on the joint surface 12a of the base 12 of the handle grip 6 are
Due to the shape of the mortise hole 42 formed in the joint surface 4a of the handle switch box 40 that receives the shift lever, the upper and lower limits of the gear shift operation position can be regulated within a desired range, and excessive rotation of the handle grip 6 can be prevented. .

In addition, the locking mechanism 16 of the handle grip 6
Since the thumb of the left hand is in a position where it can reach a predetermined location on the base 12 without moving the left hand, operation of the locking mechanism 16 becomes extremely easy.

Furthermore, since the shift command switch section 38 is provided using the existing handle switch box 4 and handle grip 6, the configuration can be simplified.

Furthermore, since the lock mechanism 16 and the light emitting diode 40 are provided on the handle grip 6, and the phototransistor 50 is provided on the handle switch box 4, assembly of each component is facilitated.

In addition, since the gear change command signal is transmitted using visible light,
No waterproofing measures are required, and the configuration can be simplified.

Further, the light emitting diode 40 and the phototransistor 50 are arranged in a large radial area (outside) of the handle grip 6 and the handle switch box 4.
Since it can be embedded in a large area, it is possible to increase the operating angle and reduce malfunctions.

Therefore, by providing an indicator that displays the shift command position, when the handle grip is rotated, the light receiving element corresponding to the shift command position receives visible light from the light emitting element and sends a shift command signal to the electric transmission. This makes it possible to simplify the gear shifting operation and improve operability, as well as to improve safety during driving.

Further, since no mechanical contact is required, the durability of the shift command switch section is improved, and the reliability of the shift operation can be improved.

Furthermore, since a shift indicator is provided to display the position of the gear change command to the electric transmission, the visible light from the light emitting element illuminates the position of the gear change command on the shift indicator, making it possible to confirm the position of the gear change command. This can provide a sense of security to the driver, especially when the transmission is indirectly operated by a human, such as an electric transmission.
