Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIG. 1, the throttle grip device according to the first embodiment detects an angle of rotation of a throttle grip G attached to a handle pipe of a motorcycle, and an electronic control device such as an ECU mounted on the motorcycle for detecting the rotation angle. 1 to 10, and includes an interlocking member 1, a magnetic sensor 2 (rotation angle detecting means), a return spring 3, a holding member 4, and a case C, as shown in FIGS. It is configured.

The interlocking member 1 can rotate together with the rotating operation of the throttle grip G of the vehicle, and as shown in FIGS. 5 and 6, is made of a substantially cylindrical resin molded product, and has a fitting portion Ga (see FIG. 2) of the throttle grip G. (Refer to FIG. 3), a receiving recess 1b for receiving the return spring 3, an engaging portion 1c for engaging one end 3a of the return spring 3, and a protruding portion at a predetermined position. A stopper portion 1d is formed.

Further, the interlocking member 1 according to the present embodiment has an arc-shaped magnet m attached to one end surface thereof. The magnet m is configured such that the magnetic field continuously changes in the circumferential direction, and can rotate as the interlocking member 1 rotates. The magnet m may have a helical surface that bends in an arc shape and continuously changes in height. In that case, the magnet m is attached to the interlocking member 1 so as to face the helical surface. It is necessary to dispose the magnetic sensor 2 (rotation angle detecting means).

Further, the accommodating concave portion 1b has a groove shape formed in an annular shape on one end surface of the interlocking member 1, and a locking portion 1c is formed in a part thereof. Then, when the return spring 3 is housed in the housing recess 1b, as shown in FIGS. 7 and 8, the coil portion 3c is fitted in the housing recess 1b, and the one end 3a is fitted in and locked by the locking portion 1c. It is like this. As a result, the return spring 3 is incorporated in the interlocking member 1, and the width dimension can be reduced.

The case C is fixed to the front end side (base end side of the throttle grip G) of the handle pipe H (see FIG. 3) of the two-wheeled vehicle (vehicle), and as shown in FIGS. The case Cb is assembled by a bolt B (see FIG. 3). As shown in FIG. 4, the lower case Ca and the upper case Cb are respectively formed with accommodating recesses. By assembling the lower case Ca and the upper case Cb, an accommodating space is formed inside. Has become.

The magnetic sensor 2 is configured to be attached. As shown in FIG. 4, a screw hole n is formed on the wall surface of the lower case Ca so that the holding member 4 can be screwed to a predetermined position in the lower case Ca.

As shown in FIGS. 2 and 3, the magnetic sensor 2 (rotation angle detecting means) is composed of a sensor disposed at a predetermined position of the lower case Ca, and detects a change in magnetism generated by the magnet m, thereby interlocking members. The rotation angle of the throttle grip G can be detected by detecting the rotation angle of 1. Specifically, the magnetic sensor 2 can obtain an output voltage according to a change in the magnetic field of the magnet m (change in magnetic flux density). For example, a Hall element (specifically, a Hall element that is a magnetic sensor utilizing the Hall effect). Is composed of a linear Hall IC) or the like capable of obtaining an output voltage proportional to the magnetic field (magnetic flux density) of the magnet m. Then, when the magnet m rotates with the rotation of the throttle grip G and the rotation of the interlocking member 1, the magnetism changes.

As a result, the magnetism changes depending on the rotation angle of the interlocking member 1, so that an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 1 (that is, the rotation angle of the throttle grip G is based on the output voltage. ) Is detected. The rotation angle of the throttle grip G detected in this way is transmitted as an electric signal to an ECU (engine control unit) mounted on the two-wheeled vehicle, and the rotation angle of the vehicle is changed according to the transmitted rotation angle of the throttle grip G. The engine can be controlled. In addition, reference numeral h in the drawing indicates a wiring extended from the magnetic sensor 2, and the detection signal is transmitted to the vehicle side via the wiring h.

It has one end 3a locked to the locking portion 1c, the other end 3b locked to the locking portion 4a of the holding member 4, and a coil portion 3c located between the one end 3a and the other end 3b. Has been done.

As described above, the return spring 3 has one end 3a attached to the interlocking member 1 and the other end 3b attached to the holding member 4, and is assembled. When the throttle grip G is rotated, the return spring 3 Since the interlocking member 1 rotates against the urging force, the urging force is transmitted to the throttle grip G, and a force for returning the throttle grip G and the interlocking member 1 to the initial position acts.

The holding member 4 holds the interlocking member 1 rotatably while positioning it, and holds the other end 3b of the return spring 3 while locking it. As shown in FIG. 10, the other end 3b of the return spring 3 is held. It is composed of a metal plate-shaped member in which a locking portion 4a that locks, a guide portion 4b that holds the interlocking member 1 while positioning it, and a holding portion 4c formed at a predetermined position are formed. A screw hole n is formed at a predetermined position of the holding member 4 so that the holding member 4 can be screwed at a predetermined position inside the lower case Ca.

The locking portion 4a is formed by bending a part of the holding member 4, and is configured to reliably lock the other end 3b of the return spring 3. The guide portion 4b is formed by a portion of the holding member 4 that is formed in an annular shape by burring or the like, and as shown in FIG. 2, the annular wall portion 1e (FIG. 8) integrally formed with the interlocking member 1 (FIG. 8). The interlocking member 1 is rotatably fitted and positioned (especially, radial positioning) by inserting (see).

That is, as shown in FIGS. 7 and 8, after the return spring 3 is accommodated in the accommodation recess 1b, the other end 3b of the return spring 3 is engaged with the engaging portion 4a of the holding member 4 and then the return spring 3 is engaged. The holding member 4 and the interlocking member 1 are relatively rotated by a certain angle in a direction in which the coil portion 3c is twisted and a predetermined biasing force is generated, and the stopper portion 1d of the interlocking member 1 is brought into contact with the holding portion 4c of the holding member 4. In this abutting state, the holding portion 4c of the holding member 4 receives the urging force of the return spring 3 in the rotation direction α, so that the holding member 4 holds the interlocking member 1 urged by the return spring 3 in the rotation direction α. can do.

As a result, the interlocking member 1 is biased in the axial direction β. As a result, the interlocking member 1 is assembled with one end surface thereof being pressed against the sliding surface N of the case C by the urging force of the return spring 3 in the axial direction β.

Then, when the throttle grip G is rotationally operated, the interlocking member 1 rotates against the biasing force of the return spring 3 in the rotational direction α, and one end surface of the interlocking member 1 presses the sliding surface N of the case C. It will slide in the state where it was kept. On the other hand, when an attempt is made to rotate the throttle grip G from the initial position to the opposite side, the stopper portion 1d of the interlocking member 1 is in contact with the holding portion 4c of the holding member 4, so the throttle grip G is moved from the initial position. It is possible to prevent rotation operation toward the opposite side.

In particular, since the holding member 4 according to the present embodiment is made of a plate-shaped member, it is possible to make the throttle grip device thinner.

Furthermore, since the return spring 3 according to the present embodiment biases the interlocking member 1 in the axial direction β in addition to the rotation direction α, the interlocking member 1 is pressed in the axial direction β while having elasticity. The backlash can be absorbed, the rotation of the interlocking member 1 can be stably performed, and the operability of the throttle grip G can be maintained. Further, since the interlocking member 1 according to the present embodiment is provided separately from the throttle grip G, it is possible to prevent an excessive load applied to the throttle grip G from being transmitted to the interlocking member. Exchange of the interlocking member 1 or the throttle grip G can be facilitated.

In addition, according to this embodiment, the interlocking member 1 has the accommodation recess 1b for accommodating the return spring 3 and interlocks with the other end 3b of the return spring 3 accommodated in the accommodation recess 1b being locked.

When the throttle grip G is rotated in the forward direction α1, Since the interlocking member 1 rotates against the urging force of the return spring 3, the urging force is transmitted to the throttle grip G, and a force for returning the throttle grip G and the interlocking member 1 to the initial position acts.

The reverse rotation return spring 6 is composed of a coil spring that biases the throttle grip G and the interlocking member 1 in the rotational direction toward the initial position when the throttle grip G is rotated in the reverse direction α2. It is stored in the formed storage recess 1i (see FIG. 17). Further, as shown in FIGS. 19 and 20, the slide member 5 is attached to the accommodation recess 1i of the interlocking member 1, and the reverse rotation return spring 6 is compressed by the movement of the slide member 5 to generate a biasing force. It is like this.

As shown in FIGS. 19 and 20, the slide member 5 is formed of an arc-shaped component that extends in the circumferential direction of the interlocking member 1, and as shown in FIGS. 24 to 27, a housing recess 5 a that holds the reverse rotation return spring 6. , A spring receiving portion 5b that receives one end of the reverse rotation return spring 6, an abutting portion 5c that abuts the holding portion 4c of the holding member 4 (see FIG. 23), and a guide groove 1g formed in the interlocking member 1 (FIG. 22). The protrusion 5d that is inserted into the reference portion) is integrally formed.

When the slide member 5 in which the reverse rotation return spring 6 is held in the storage recess 5a is housed in the storage recess 1i of the interlocking member 1, one end of the reverse rotation return spring 6 is attached to the spring receiving portion 5b of the slide member 5. And the other end of the reverse rotation return spring 6 comes into contact with the wall of the accommodation recess 5a. Accordingly, when the throttle grip G is rotationally operated in the reverse direction α2, the slide member 5 moves in the circumferential direction with respect to the interlocking member 1 to compress the reverse rotation return spring 6, and the reverse rotation return spring. Since the urging force generated by the compression of 6 is applied to the throttle grip G, a force that returns the throttle grip G and the interlocking member 1 to the initial position acts.

Further, when the slide member 5 is assembled in the accommodation recess 1i of the interlocking member 1, the protrusion 5d of the slide member 5 is configured to be inserted into the guide groove 1g of the interlocking member 1, and the throttle grip G is in the reverse direction α2. When rotated, the protrusion 5d moves along the guide groove 1g, so that the movement of the slide member 5 is guided by the guide groove 1g. As a result, the slide member 5 can be moved smoothly and accurately.

As shown in FIGS. 15 and 16, the magnetic sensor 2 (rotation angle detecting means) is composed of a sensor disposed at a predetermined position of the lower case Ca, and detects a change in magnetism generated by the magnet m, thereby interlocking members. The rotation angle of the throttle grip G can be detected by detecting the rotation angle of 1. Specifically, the magnetic sensor 2 can obtain an output voltage according to a change in the magnetic field of the magnet m (change in magnetic flux density). For example, a Hall element (specifically, a Hall element that is a magnetic sensor utilizing the Hall effect). Is composed of a linear Hall IC) or the like capable of obtaining an output voltage proportional to the magnetic field (magnetic flux density) of the magnet m. Then, when the magnet m rotates with the rotation of the throttle grip G and the rotation of the interlocking member 1, the magnetism changes.

As a result, the magnetism changes depending on the rotation angle of the interlocking member 1, so that an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 1 (that is, the rotation angle of the throttle grip G is based on the output voltage. ) Is detected. The rotation angle of the throttle grip G detected in this way is transmitted as an electric signal to an ECU (engine control unit) mounted on the two-wheeled vehicle, and the rotation angle of the vehicle is changed according to the transmitted rotation angle of the throttle grip G. The engine can be controlled. In addition, reference numeral h in the drawing indicates a wiring extended from the magnetic sensor 2, and the detection signal is transmitted to the vehicle side via the wiring h.

Further, the magnetic sensor 2 according to the present embodiment is capable of detecting the rotational operation of the throttle grip G in the forward direction α1 and the reverse direction α2. As a result, the driver can control the engine E according to the rotation angle of the throttle grip G by rotating the driver in the forward direction α1 from the initial position while gripping the throttle grip G, so that the vehicle travels at an arbitrary speed. In addition to this, the throttle grip Gw can be operated in the reverse direction α2 from the initial position to activate or deactivate the electrical component mounted on the vehicle (for example, the cruise control cancel function).

Further, in the interlocking member 1 according to the present embodiment, as shown in FIGS. 17 to 20, the return spring 3 is attached to the inner diameter side, and the reverse rotation return is provided at a portion on the outer diameter side from the attachment position of the return spring 3. The spring 6 is attached, and the magnet m and the slide member 5 are arranged side by side in the circumferential direction of the interlocking member 1. Further, in the interlocking member 1 according to the present embodiment, the spring 7 and the pressing component 8 are attached in the circumferential direction in which the magnet m and the slide member 5 are arranged side by side, and the pressing component 8 is held by the biasing force of the spring 7. It is configured to be biased toward the member 4. As a result, when the interlocking member 1 is rotated, a desired frictional force is applied to improve the operational feeling.

Similar to the first embodiment, the holding member 4 holds the interlocking member 1 rotatably while positioning it, and holds the other end 3b of the return spring 3 while locking it. As shown in FIG. A metal plate having a locking portion 4a that locks the other end 3b of the return spring 3, a guide portion 4b that holds the interlocking member 1 while positioning it, and a holding portion 4c formed at a predetermined position. It consists of a member. A screw hole n is formed at a predetermined position of the holding member 4 so that the holding member 4 can be screwed at a predetermined position inside the lower case Ca.

The locking portion 4a is formed by bending a part of the holding member 4, and is configured to reliably lock the other end 3b of the return spring 3. The guide portion 4b includes a portion formed by projecting a part of the holding member 4 into a ring shape by a burring process or the like, and as shown in FIG. 15, a ring-shaped wall portion 1e integrally formed with the interlocking member 1 (FIG. 20). The interlocking member 1 is rotatably fitted and positioned (especially, radial positioning) by inserting (see).

As shown in FIGS. 22 and 23, the holding portion 4c is composed of a portion that abuts on the abutting portion 5c of the slide member 5 and holds it in the circumferential direction, and the throttle grip G is rotationally operated in the reverse direction α2. When the interlocking member 1 rotates in one direction, the interlocking member 1 and the slide member 5 can be relatively moved by locking the slide member 5 and restricting the rotation in the same direction. As a result, when the throttle grip G is rotationally operated in the reverse direction α2, the interlocking member 1 and the slide member 5 relatively move to compress the reverse rotation return spring 6 and the reverse rotation return spring 6 moves. The biasing force generated by the compression is applied to the throttle grip G. When the throttle grip G is rotated by a predetermined angle in the reverse direction α2, the stopper portion 1d of the interlocking member 1 comes into contact with the contact portion 5c locked by the holding portion 4c, and further rotation operation is performed. Regulated.

On the other hand, when the throttle grip G is rotationally operated in the reverse direction α2, the biasing force of the return spring 3 is generated in the opposite direction to the biasing force generated by the reverse rotation return spring 6, but the reverse rotation return spring 6 is generated. Is set to be larger than the biasing force of the return spring 3, only the biasing force of the reverse rotation return spring 6 is applied to the interlocking member 1 and the throttle grip G. When the throttle grip G is rotationally operated in the forward direction α1, the contact portion 5c of the slide member 5 moves in the direction away from the holding portion 4c, so that the slide member 5 rotates together with the interlocking member 1 and reversely rotates. The return spring 6 does not generate an urging force.

In addition, in the present embodiment, after the return spring 3 is accommodated in the accommodation recess 1b, the other end 3b of the return spring 3 is engaged with the engaging portion 4a of the holding member 4, and then the coil portion of the return spring 3 is provided. The holding member 4 and the interlocking member 1 are relatively rotated by a certain angle in a direction in which the predetermined biasing force is generated by twisting 3c, and the holding portion 4c of the holding member 4 is brought into contact with the abutting portion 5c of the slide member 5.

However, since the return spring 3 according to the present embodiment is set to have an initial load lower than that of the reverse rotation return spring 6, the reverse rotation return spring is in the contact state of the contact portion 5c and the holding portion 4c. 6 is not compressed, the holding portion 4c of the holding member 4 receives the biasing force of the return spring 3, and the holding member 4 can hold the interlocking member 1 biased by the return spring 3.

As a result, the holding member 4 holds the interlocking member 1 with a predetermined biasing force by locking the other end 3b of the return spring 3 housed in the housing recess 1b, as shown in FIGS. The interlocking member 1, the return spring 3, and the reverse rotation return spring 6 are integrally configured. In this way, the interlocking member 1, the return spring 3, and the reverse rotation return spring 6 which are integrally configured by the holding member 4 are a unit Y and are attached to a predetermined position in the case C as shown in FIG. Fixed.

Further, in the return spring 3 according to the present embodiment, as in the first embodiment, in addition to the rotational direction (direction toward the initial position when the throttle grip G is rotated in the forward direction α1), the interlocking member 1 is axially moved. It is supposed to be biased to β. Specifically, as shown in FIG. 9, the return spring 3 according to the present embodiment is a coil portion 3c in which a gap is formed between adjacent windings, and is integrally configured by the holding member 4. In the closed state (the state of the unit Y shown in FIGS. 21 to 23), as shown in FIG. 15, when it is housed in the case C, it is compressed in the direction in which the gap between the windings of the coil portion 3c becomes smaller. Therefore, the interlocking member 1 is biased in the axial direction β.

As a result, the interlocking member 1 is assembled with one end surface thereof being pressed against the inner peripheral surface of the case C by the urging force of the return spring 3 in the axial direction β. Therefore, when the throttle grip G is rotationally operated, the interlocking member 1 rotates against the urging force of the return spring 3 or the reverse rotation return spring 6, and one end surface of the interlocking member 1 becomes the inner peripheral surface of the case C. It will slide in the pressed state.

The magnet m is configured such that the magnetic field continuously changes in the circumferential direction, and can rotate as the interlocking member 1 rotates. The magnet m may have a helical surface that bends in an arc shape and continuously changes in height. In that case, the magnet m is attached to the interlocking member 1 so as to face the helical surface. It is necessary to dispose the magnetic sensor 2 (rotation angle detecting means).

Further, the accommodating recessed portion 1b has a groove shape formed in an annular shape on one end surface of the interlocking member 1, and a locking portion 1c continuous with a part thereof is formed. When the return spring 3 is housed in the housing recess 1b, as shown in FIGS. 35 and 36, the coil portion 3c is fitted in the housing recess 1b and one end 3a is fitted in and locked by the locking portion 1c. It is like this. As a result, the return spring 3 is incorporated in the interlocking member 1, and the width dimension can be reduced.

Further, the interlocking member 1 according to the present embodiment has a protruding portion 1h integrally formed in the outer diameter direction as shown in FIGS. The protruding portion 1h has an inclined surface Q formed on one surface thereof, and as shown in FIG. 40, the operating portion Sa of the micro switch S mounted on the upper case Cb can be pressed by the inclined surface Q. ing. That is, the attachment part T is fixed to the attachment part Cb1 formed at a predetermined position of the upper case Cb with the attachment bolt f, and the microswitch S is attached to the attachment part T.

It is attached so as to be orthogonal to the direction. Then, when the interlocking member 1 rotates in the reverse direction α2, the operating portion Sa of the micro switch S is pressed by the inclined surface Q and retracts, so that the switch is electrically turned on.

The case C is fixed to the tip end side (base end side of the throttle grip G) of the handle pipe H (see FIG. 30) of the two-wheeled vehicle (vehicle), as in the first and second embodiments. As shown in, the lower case Ca and the upper case Cb are assembled by bolts B (see FIG. 30). As shown in FIG. 32, housing recesses are formed in the lower case Ca and the upper case Cb, respectively. By assembling the lower case Ca and the upper case Cb, a housing space is formed inside. Has become.

The magnetic sensor 2 (rotation angle detecting means), the return spring 3, the holding member 4, the slide member 5, the reverse rotation return spring 6, the spring 7 and the pressing component 8 are the same as in the first and second embodiments. Since these are components, detailed description thereof will be omitted. Further, the throttle grip G according to the present embodiment is, like the second embodiment, capable of being gripped by the driver and rotationally operated with respect to the handle pipe H (see FIG. 30) of the motorcycle. As shown in FIG. 3, both a forward rotation operation (α1) for rotating the driver toward the front side and a reverse rotation operation (α2) for rotating the driver away from the driver are possible. Has been done.

However, in the return spring 3 according to the present embodiment, as in the second embodiment, the initial setting load is set lower than that of the reverse rotation return spring 6, so that the contact state of the contact portion 5c and the holding portion 4c is in the contact state. In the above, the reverse rotation return spring 6 is not compressed, the holding portion 4c of the holding member 4 receives the biasing force of the return spring 3, and the holding member 4 moves the interlocking member 1 biased by the return spring 3. Can be held.

As a result, the holding member 4 holds the interlocking member 1 with a predetermined biasing force by locking the other end 3b of the return spring 3 housed in the housing recess 1b, as shown in FIGS. The interlocking member 1, the return spring 3, and the reverse rotation return spring 6 are integrally configured. As described above, the interlocking member 1, the return spring 3, and the reverse rotation return spring 6 which are integrally configured by the holding member 4 are set as a unit Y and are placed at a predetermined position in the case C as shown in FIGS. Installed and fixed.

Further, the return spring 3 according to the present embodiment is similar to the first and second embodiments in that the interlocking member 1 is added in addition to the rotation direction (direction toward the initial position when the throttle grip G is rotated in the forward direction α1). It is supposed to bias in the axial direction β. Specifically, as shown in FIG. 9, the return spring 3 according to the present embodiment is a coil portion 3c in which a gap is formed between adjacent windings, and is integrally configured by the holding member 4. 29 and 31, in the closed state (the state where the unit Y is the unit Y shown in FIGS. 35 to 39), the gap between the windings of the coil portion 3c becomes smaller when housed in the case C. By being compressed, the interlocking member 1 is biased in the axial direction β.

As a result, the interlocking member 1 is assembled with one end surface thereof being pressed against the inner peripheral surface of the case C by the urging force of the return spring 3 in the axial direction β. Therefore, when the throttle grip G is rotationally operated, the interlocking member 1 rotates against the urging force of the return spring 3 or the reverse rotation return spring 6, and one end surface of the interlocking member 1 becomes the inner peripheral surface of the case C. It will slide in the pressed state.

Here, in the throttle grip device according to the present embodiment, when the throttle grip G is rotationally operated from the initial position in the forward direction α1, the engine of the vehicle according to the rotation angle of the throttle grip G detected by the magnetic sensor 2. When the throttle grip G is rotated in the reverse direction α2 from the initial position, electrical components (for example, a cruise control cancel function) mounted on the vehicle are activated or deactivated. ing.

Specifically, the magnetic sensor 2 according to the present embodiment is capable of detecting the rotational operation of the throttle grip G in the forward direction α1 and detects the rotational operation of the throttle grip G in the reverse direction α2 by the microswitch S. This is possible, and the micro switch S is electrically connected to the electrical equipment mounted on the vehicle. When the micro switch S detects that the throttle grip G has rotated in the reverse direction α2 from the initial position, the detection signal is output to activate or deactivate the electric components mounted on the vehicle. Has been done.

As a result, the driver can control the engine E according to the rotation angle of the throttle grip G by rotating the driver in the forward direction α1 from the initial position while gripping the throttle grip G, so that the vehicle travels at an arbitrary speed. In addition to this, the throttle grip Gw can be operated in the reverse direction α2 from the initial position to activate or deactivate the electrical component mounted on the vehicle (for example, the cruise control cancel function).

According to the second and third embodiments, the throttle grip G can be rotated in the forward direction α1 and the reverse direction α2, and when the throttle grip G is rotated in the forward direction α1 from the initial position, The throttle grip G and the interlocking member 1 are urged in the rotational direction toward the initial position by the return spring 3, and when the throttle grip G is rotationally operated in the reverse direction α2 from the initial position, the throttle grip G Since the reverse rotation return spring 6 for urging the G and the interlocking member 1 in the rotation direction toward the initial position is provided, the throttle grip G is operated during the rotation operation in the forward direction α1 and the reverse direction α2. The feeling can be made different, and an appropriate biasing force can be applied during each operation.

Further, in the interlocking member 1 according to the second and third embodiments, the return spring 3 is attached to the inner diameter side, and the reverse rotation return spring 6 is attached to the outer diameter side portion from the attachment position of the return spring 3. Therefore, the return spring 3 and the reverse rotation return spring 6 can be arranged in the radial direction of the interlocking member 1, and it is possible to prevent the dimension in the width direction from increasing.

Furthermore, when the slide member 5 holding the reverse rotation return spring 6 is attached and the throttle grip G is rotationally operated in the reverse direction α2, the interlocking member 1 according to the second and third embodiments is concerned. The slide member 5 moves with respect to the interlocking member 1 to compress the reverse rotation return spring 6, and the biasing force generated by the compression of the reverse rotation return spring 6 is applied to the throttle grip G. The rotational force in the reverse direction α2 can be smoothly and reliably transmitted to the slide member 5, and the biasing force of the reverse rotation return spring 6 can be efficiently applied to the throttle grip G.

In addition, the slide member 5 according to the second and third embodiments is composed of an arc-shaped component extending in the circumferential direction of the interlocking member 1, and when the throttle grip G is rotationally operated in the reverse direction α2, the interlocking member 1 is moved. Since the return spring 6 for reverse rotation can be compressed by moving in the circumferential direction, the slide member 5 and its moving range can be easily formed with respect to the interlocking member 1.

Further, the magnetic sensor 2 (rotation angle detecting means) according to the second and third embodiments described above rotates the interlocking member 1 by detecting a change in magnetism generated from the magnet m attached to a predetermined position of the interlocking member 1. Since the magnet m and the slide member 5 are arranged side by side in the circumferential direction of the interlocking member 1, it is possible to suppress an increase in the radial dimension of the interlocking member 1 while being composed of a sensor capable of detecting an angle. Therefore, the throttle grip device can be downsized.

Further, according to the second embodiment, the rotational operation of the throttle grip G in the forward direction α1 and the reverse direction α2 can be detected by the magnetic sensor 2 (rotation angle detecting means), so that the reverse direction α2 of the throttle grip G is detected. It is possible to eliminate the need for a separate switch for detecting the rotation operation of, and to reduce the number of parts. On the other hand, according to the third embodiment, the rotational operation of the throttle grip G in the forward direction α1 can be detected by the magnetic sensor 2 (rotation angle detecting means), and the rotational operation of the throttle grip G in the reverse direction α2 can be detected.

In this case, the number of parts can be reduced and the assembling workability of the throttle grip device can be improved as compared with the case where the interlocking member 1 is provided separately from the throttle grip G.

Further, instead of the magnetic sensor 2 that detects the rotation angle of the throttle grip G, other general-purpose sensors (not limited to those that detect the magnetism of a magnet, but not limited to non-contact sensors, contact sensors, etc.) Also included). Further, instead of the magnet m, the magnet may be magnetized in the circumferential direction of the interlocking member 1. The vehicle to be applied is not limited to the two-wheeled vehicle as in the present embodiment, but may be applied to other vehicles having the handlebar H (for example, ATV, snowmobile, etc.).
