Embodiments of the present invention will be specifically described below with reference to the drawings.
As shown in FIG. 1, the throttle grip device according to the first embodiment detects the rotation angle of a throttle grip G attached to a handle pipe of a two-wheeled vehicle, and transmits the detection signal to an electronic control device such as an ECU mounted on the two-wheeled vehicle. 1 to 10, it has an interlocking member 1, a magnetic sensor 2 (rotation angle detection means), a return spring 3, a holding member 4, and a case C. It is configured.

The interlocking member 1 can rotate with the rotational operation of the throttle grip G of the vehicle, and is made of a substantially cylindrical resin molded product, as shown in FIGS. ), a housing recess 1b for housing the return spring 3, a locking portion 1c for locking one end 3a of the return spring 3, and a locking portion 1c protruding at a predetermined position. A stopper portion 1d is formed.

Further, the interlocking member 1 according to this embodiment has an arc-shaped magnet m attached to one end surface thereof. The magnet m is configured such that its magnetic field changes continuously in the circumferential direction, and can rotate as the interlocking member 1 rotates. The magnet m may have a helical surface whose height changes continuously while being bent into an arc shape. It is necessary to provide a magnetic sensor 2 (rotation angle detection means).

Further, the housing recess 1b is formed in the shape of a ring-shaped groove on one end surface of the interlocking member 1, and a locking portion 1c is formed in a part of the groove. When the return spring 3 is accommodated in the accommodation recess 1b, the coil portion 3c is fitted into the accommodation recess 1b and the one end 3a is fitted into the locking portion 1c and locked, as shown in FIGS. 7 and 8. It looks like this. Thereby, the return spring 3 is included in the interlocking member 1, and the width dimension can be reduced.

Case C is fixed to the tip side (base end side of throttle grip G) of handle pipe H (see Fig. 3) of a two-wheeled vehicle (vehicle), and as shown in Figs. It is constructed by assembling the case Cb with bolts B (see FIG. 3). As shown in FIG. 4, each of the lower case Ca and the upper case Cb has a housing recess formed therein, so that when the lower case Ca and the upper case Cb are assembled, a housing space is formed inside. It has become.

Further, as shown in FIGS. 2 and 3, the lower case Ca has a sliding surface N on which one end surface of the interlocking member 1 can slide in contact with it, and is located at a position where magnetic changes of the magnet m can be detected. The magnetic sensor 2 is configured to be attached thereto. Note that, as shown in FIG. 4, a screw hole n is formed in the wall surface of the lower case Ca, so that the holding member 4 can be screwed into a predetermined position within the lower case Ca.

As shown in FIGS. 2 and 3, the magnetic sensor 2 (rotation angle detection means) consists of a sensor disposed at a predetermined position on the lower case Ca, and detects changes in magnetism generated from the magnet m. 1 and the rotation angle of the throttle grip G can be detected. Specifically, the magnetic sensor 2 is capable of obtaining an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet m, and is, for example, a Hall element (specifically, is composed of a linear Hall IC (Linear Hall IC) etc. that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnet m. Therefore, when the throttle grip G is rotated and the interlocking member 1 is rotated, the magnet m is rotated, and the magnetism changes.

As a result, the magnetism changes depending on the rotation angle of the interlocking member 1, so it is possible to obtain an output voltage according to the rotation angle, and based on the output voltage, the rotation angle of the interlocking member 1 (i.e., the rotation angle of the throttle grip G). ) can be detected. The rotation angle of the throttle grip G detected in this way is transmitted as an electrical signal to the ECU (engine control unit) mounted on the motorcycle, and the vehicle is controlled according to the transmitted rotation angle of the throttle grip G. The engine can now be controlled. Note that the symbol h in the figure indicates a wiring extending from the magnetic sensor 2, and the configuration is such that a detection signal is transmitted to the vehicle side via the wiring h.

The return spring 3 is a torsion coil spring that biases the throttle grip G and the interlocking member 1 toward the initial position in the rotational direction α when the throttle grip G is rotated, and as shown in FIG. It has one end 3a that is locked to the locking part 1c, the other end 3b that is locked to the locking part 4a of the holding member 4, and a coil part 3c located between the one end 3a and the other end 3b. has been done.

In this way, the return spring 3 is assembled with one end 3a attached to the interlocking member 1 and the other end 3b attached to the holding member 4, and 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 acts to return the throttle grip G and the interlocking member 1 to their initial positions.

The holding member 4 positions and rotatably holds the interlocking member 1, and also locks and holds the other end 3b of the return spring 3. As shown in FIG. It is made of a metal plate-like member having a locking part 4a that locks the interlocking member 1, a guide part 4b that positions and holds the interlocking member 1, and a holding part 4c formed at a predetermined position. Note that a screw hole n is formed at a predetermined position of the holding member 4, so that the holding member 4 can be screwed to a predetermined position within 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 consists of a portion of the holding member 4 that is formed in a protruding annular shape by burring or the like, and as shown in FIG. ), the interlocking member 1 can be rotatably fitted and positioned (especially radial positioning).

The holding portion 4c is held in contact with the stopper portion 1d of the interlocking member 1 which is biased in the rotational direction by the return spring 3. That is, as shown in FIGS. 7 and 8, with the return spring 3 accommodated in the accommodation recess 1b, after the other end 3b of the return spring 3 is engaged with the engagement portion 4a of the holding member 4, the return spring 3 is 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 holding portion 4c of the holding member 4 is brought into contact with the stopper portion 1d of the interlocking member 1. In this contact state, the holding portion 4c of the holding member 4 receives the urging force in the rotational direction α of the return spring 3, so that the holding member 4 holds the interlocking member 1 urged in the rotational direction α by the return spring 3. can do.

As a result, the holding member 4 locks the other end 3b of the return spring 3 accommodated in the accommodation recess 1b and holds the interlocking member 1 with a predetermined urging force in the rotational direction α. As shown in 13, the interlocking member 1 and the return spring 3 are integrally constructed. In this way, the interlocking member 1 and the return spring 3 integrally formed by the holding member 4 form a unit Y, which is attached and fixed at a predetermined position within the case C, as shown in FIG.

Furthermore, the return spring 3 according to this embodiment is configured to bias the interlocking member 1 in the axial direction β in addition to the rotational direction α. Specifically, as shown in FIG. 9, the return spring 3 according to the present embodiment has a coil portion 3c in which a gap is created between adjacent windings, and is integrated with a holding member 4. When the unit Y is housed in the case C as shown in FIG. 2, the coil portion 3c is compressed in a direction that reduces the gap between the windings of the coil portion 3c. 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 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.

When the throttle grip G is rotated, the interlocking member 1 rotates against the urging force of the return spring 3 in the rotation direction α, and one end surface of the interlocking member 1 is pressed against the sliding surface N of the case C. It will slide in this state. On the other hand, when attempting to rotate the throttle grip G from the initial position toward 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 rotated from the initial position. It is designed to prevent rotational operation toward the opposite side.

According to the present embodiment, since the holding member 4 is provided which holds the interlocking member 1 rotatably while positioning it, and holds the other end 3b of the return spring 3 while locking it, the rotation of the interlocking member 1 is stabilized. In addition, the return spring 3 can be locked at an appropriate position. Furthermore, the holding member 4 according to the present embodiment has a guide portion 4b that is formed in a protruding annular shape, and the interlocking member 1 is rotatably fitted to the guide portion 4b for positioning, so that it has a simple configuration. Positioning of the interlocking member 1, especially radial positioning, can be performed reliably.

Further, the holding member 4 according to the present embodiment has a guide portion, a locking portion 4a that locks the other end 3b of the return spring 3, and abuts against the interlocking member 1 urged in the rotational direction α by the return spring 3. Since the holding part 4c is held in contact with the holding part 4c, the guide part 4b can position the interlocking member 1 in the radial direction, the locking part 4a can lock the return spring 3, and the holding part 4c can hold the interlocking member 1. 4 can be performed together. In particular, since the holding member 4 according to this embodiment is made of a plate-like member, it is possible to reduce the thickness of the throttle grip device.

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 rotational direction α, it presses the interlocking member 1 with elasticity in the axial direction β. Backlash can be absorbed, the interlocking member 1 can be rotated stably, and the operability of the throttle grip G can be maintained. Furthermore, since the interlocking member 1 according to the present embodiment is separate from the throttle grip G, it is possible to suppress excessive load applied to the throttle grip G from being transmitted to the interlocking member. The interlocking member 1 or the throttle grip G can be easily replaced.

In addition, according to the present embodiment, the interlocking member 1 has the accommodation recess 1b for accommodating the return spring 3, and is interlocked with the other end 3b of the return spring 3 accommodated in the accommodation recess 1b. Since the holding member 4 is attached to the member 1 and has the interlocking member 1 and the return spring 3 as an integral structure, it is possible to improve the assembly workability by integrating the interlocking member 1 and the return spring 3. The width dimension required for assembling the member 1 and the return spring 3 can be reduced.

Further, the holding member 4 according to the present embodiment is held by being in contact with the locking portion 4a that locks the other end 3b of the return spring 3 and the interlocking member 1 urged in the rotational direction α by the return spring 3. Since the holding portion 4c has a holding portion 4c, the urging force of the return spring 3 can be reliably applied to the interlocking member 1, and the integral structure of the interlocking member 1 and the return spring 3 can be reliably held. Furthermore, since the holding member 4 according to the present embodiment is attached to the interlocking member 1 with the accommodation recess 1b closed, it is possible to avoid foreign objects etc. from entering the accommodation recess 1b, and the return spring 3 It is possible to reliably apply the biasing force to 1.

When the slide member 5 with the return spring 6 for reverse rotation held in the accommodation recess 5a is accommodated in the accommodation recess 1i of the interlocking member 1, one end of the return spring 6 for reverse rotation is held in the spring receiving portion 5b of the slide member 5. At the same time, the other end of the return spring 6 for reverse rotation is brought into contact with the wall of the accommodation recess 5a. As a result, when the throttle grip G is rotated in the reverse direction α2, the slide member 5 moves in the circumferential direction relative to the interlocking member 1 and compresses the return spring 6 for reverse rotation. 6 is applied to the throttle grip G, so that a force is applied to return the throttle grip G and the interlocking member 1 to their initial positions.

Further, when the slide member 5 is assembled into 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 moved in the reverse direction α2. When the rotating operation is performed, the protruding portion 5d moves along the guide groove 1g, so that the movement of the slide member 5 is guided by the guide groove 1g. Thereby, the slide member 5 can be moved smoothly and accurately.

As shown in FIGS. 15 and 16, the magnetic sensor 2 (rotation angle detection means) consists of a sensor disposed at a predetermined position on the lower case Ca, and detects changes in the magnetism generated from the magnet m. 1 and the rotation angle of the throttle grip G can be detected. Specifically, the magnetic sensor 2 is capable of obtaining an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet m, and is, for example, a Hall element (specifically, is composed of a linear Hall IC (Linear Hall IC) etc. that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnet m. Therefore, when the throttle grip G is rotated and the interlocking member 1 is rotated, the magnet m is rotated, and the magnetism changes.

As a result, the magnetism changes depending on the rotation angle of the interlocking member 1, so it is possible to obtain an output voltage according to the rotation angle, and based on the output voltage, the rotation angle of the interlocking member 1 (i.e., the rotation angle of the throttle grip G). ) can be detected. The rotation angle of the throttle grip G detected in this way is transmitted as an electrical signal to the ECU (engine control unit) mounted on the motorcycle, and the vehicle is controlled according to the transmitted rotation angle of the throttle grip G. The engine can now be controlled. Note that the symbol h in the figure indicates a wiring extending from the magnetic sensor 2, and the configuration is such that a 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 rotational operations of the throttle grip G in the forward direction α1 and the reverse direction α2. As a result, when the driver holds the throttle grip G and rotates it in the positive direction α1 from the initial position, the engine E can be controlled according to the rotation angle of the throttle grip G, and driving at any speed is possible. By rotating the throttle grip Gw in the reverse direction α2 from the initial position, it is possible to activate or deactivate electrical components installed in the vehicle (for example, a cruise control cancel function, etc.).

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

As in the first embodiment, the holding member 4 positions and rotatably holds the interlocking member 1, and also locks and holds the other end 3b of the return spring 3, as shown in FIG. , a metal plate having a locking part 4a that locks the other end 3b of the return spring 3, a guide part 4b that positions and holds the interlocking member 1, and a holding part 4c formed at a predetermined position. It consists of a shaped member. Note that a screw hole n is formed at a predetermined position of the holding member 4, so that the holding member 4 can be screwed to a predetermined position within 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 protruding a part of the holding member 4 into an annular shape by burring or the like, and as shown in FIG. ), the interlocking member 1 can be rotatably fitted and positioned (especially radial positioning).

As shown in FIGS. 22 and 23, the holding part 4c is composed of a part that contacts the contact part 5c of the slide member 5 and holds it in the circumferential direction, and when the throttle grip G is rotated in the opposite direction α2, When the interlocking member 1 rotates in the direction, the interlocking member 1 and the slide member 5 can be moved relatively by locking the slide member 5 and restricting rotation in the same direction. As a result, when the throttle grip G is rotated in the reverse direction α2, the interlocking member 1 and the slide member 5 move relatively, compressing the return spring 6 for reverse rotation, and compressing the return spring 6 for reverse rotation. The biasing force generated by compression is applied to the throttle grip G. Note that 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 that is locked by the holding portion 4c, and further rotation operation is prevented. Regulated.

On the other hand, when the throttle grip G is rotated in the reverse direction α2, although 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, the reverse rotation return spring 6 Since the biasing force of the return spring 3 is set larger than that of the return spring 3, only the biasing force of the return spring 6 for reverse rotation is applied to the interlocking member 1 and the throttle grip G. Note that when the throttle grip G is rotated in the forward direction α1, the contact portion 5c of the slide member 5 moves in a direction away from the holding portion 4c, so the slide member 5 rotates together with the interlocking member 1 and rotates in the reverse direction. No urging force is generated by the return spring 6.

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

However, since the return spring 3 according to the present embodiment has an initial setting load lower than that of the return spring 6 for reverse rotation, when the contact portion 5c and the holding portion 4c are in contact with each other, the return spring for reverse rotation 6 is not compressed, the holding portion 4c of the holding member 4 receives the urging force of the return spring 3, and the holding member 4 can hold the interlocking member 1 urged by the return spring 3.

As a result, the holding member 4 locks the other end 3b of the return spring 3 accommodated in the accommodation recess 1b and holds the interlocking member 1 with a predetermined biasing force, as shown in FIGS. 21 to 23. , the interlocking member 1, the return spring 3, and the return spring 6 for reverse rotation are integrally constructed. In this way, the interlocking member 1, the return spring 3, and the reverse rotation return spring 6, which are integrally constructed by the holding member 4, are formed into a unit Y, which is attached to a predetermined position in the case C, as shown in FIG. Fixed.

Furthermore, as in the first embodiment, the return spring 3 according to the present embodiment is capable of moving the interlocking member 1 in the axial direction in addition to the rotational direction (direction toward the initial position when the throttle grip G is rotated in the positive direction α1). It is supposed to bias β. Specifically, as shown in FIG. 9, the return spring 3 according to the present embodiment has a coil portion 3c in which a gap is created between adjacent windings, and is integrated with a holding member 4. When the unit Y is housed in the case C as shown in FIG. 15 in the state shown in FIGS. 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 being pressed against the inner circumferential surface of the case C by the biasing force of the return spring 3 in the axial direction β. Therefore, when the throttle grip G is rotated, the interlocking member 1 rotates against the biasing force of the return spring 3 or the return spring 6 for reverse rotation, and one end surface of the interlocking member 1 contacts the inner peripheral surface of the case C. It will slide while being pressed.

Next, a third embodiment according to the present invention will be described.
As shown in FIG. 28, the throttle grip device according to this embodiment detects the rotation angle of a throttle grip G attached to a handle pipe H of a two-wheeled vehicle, and sends the detection signal to an electronic control device such as an ECU mounted on the two-wheeled vehicle. As shown in FIGS. 28 to 37, it includes an interlocking member 1, a magnetic sensor 2 (rotation angle detection means), a return spring 3, a holding member 4, a slide member 5, and a component for reverse rotation. It includes a return spring 6, a case C, and a microswitch S.

The interlocking member 1 can rotate with the rotational operation of the throttle grip G of the vehicle, and is made of a substantially cylindrical resin molded product, as shown in FIGS. ), a housing recess 1b for housing the return spring 3, a locking portion 1c for locking one end 3a of the return spring 3, and a locking portion 1c protruding at a predetermined position. A stopper portion 1d is formed.

Further, the interlocking member 1 according to this embodiment has an arc-shaped magnet m attached to one end surface thereof. The magnet m is configured such that its magnetic field changes continuously in the circumferential direction, and can rotate as the interlocking member 1 rotates. The magnet m may have a helical surface whose height changes continuously while being bent into an arc shape. It is necessary to provide a magnetic sensor 2 (rotation angle detection means).

Further, the housing recess 1b is formed of a groove formed in an annular shape on one end surface of the interlocking member 1, and a locking portion 1c continuous with a part of the groove is formed. When the return spring 3 is accommodated in the accommodation recess 1b, the coil portion 3c is fitted into the accommodation recess 1b and the one end 3a is fitted into the locking portion 1c and locked, as shown in FIGS. 35 and 36. It looks like this. Thereby, the return spring 3 is included in the interlocking member 1, and the width dimension can be reduced.

Further, the interlocking member 1 according to the present embodiment has a protrusion 1h that is integrally formed to protrude in the outer diameter direction, as shown in FIGS. 33 to 37. The protruding portion 1h has an inclined surface Q formed on one surface, and as shown in FIG. 40, the operating portion Sa of the microswitch S attached to the upper case Cb can be pressed by the inclined surface Q. ing. That is, a mounting part T is fixed to a mounting part Cb1 formed at a predetermined position of the upper case Cb with a mounting bolt f, and a microswitch S is attached to the mounting part T.

The microswitch S according to this embodiment includes an actuating part Sa that can be operated by protruding and retracting, and as shown in FIG. It is attached so that it is perpendicular to the direction. When the interlocking member 1 rotates in the opposite direction α2, the actuating portion Sa of the microswitch S is pressed by the inclined surface Q and retreats, so that the switch is electrically turned on.

Like the first and second embodiments, the case C is fixed to the tip side (base end side of the throttle grip G) of the handle pipe H (see FIG. 30) of a two-wheeled vehicle (vehicle), and is As shown in FIG. 30, it is constructed by assembling a lower case Ca and an upper case Cb with bolts B (see FIG. 30). As shown in FIG. 32, each of the lower case Ca and the upper case Cb has a housing recess formed therein, so that when the lower case Ca and the upper case Cb are assembled, a housing space is formed inside. It has become. Note that, as shown in FIG. 32, a screw hole n is formed in the wall surface of the lower case Ca, so that the holding member 4 can be screwed into a predetermined position within the lower case Ca.

Note that the magnetic sensor 2 (rotation angle detection means), return spring 3, holding member 4, slide member 5, return spring 6 for reverse rotation, spring 7, and pressing part 8 are the same as those in the first and second embodiments. This is a component, and detailed explanation will be omitted. Further, as in the second embodiment, the throttle grip G according to the present embodiment can be gripped by the driver and can be rotated with respect to the handle pipe H (see FIG. 30) of the two-wheeled vehicle. As shown in , it is possible to perform both a rotation operation in the forward direction (α1), which rotates it in a direction toward the driver, and a rotation operation in the reverse direction (α2), which rotates it in a direction away from the driver. has been done.

However, like the second embodiment, the return spring 3 according to the present embodiment has an initial setting load lower than that of the return spring 6 for reverse rotation, so that the contact state of the contact portion 5c and the holding portion 4c is In this case, the return spring 6 for reverse rotation is not compressed, and the holding portion 4c of the holding member 4 receives the urging force of the return spring 3, and the holding member 4 moves the interlocking member 1 urged by the return spring 3. can be retained.

As a result, the holding member 4 locks the other end 3b of the return spring 3 housed in the housing recess 1b and holds the interlocking member 1 with a predetermined biasing force, as shown in FIGS. 35 to 39. , the interlocking member 1, the return spring 3, and the return spring 6 for reverse rotation are integrally constructed. In this way, the interlocking member 1, the return spring 3, and the reverse rotation return spring 6, which are integrally constituted by the holding member 4, are made into a unit Y, and are placed at a predetermined position in the case C as shown in FIGS. installed and fixed.

Furthermore, as in the first and second embodiments, the return spring 3 according to the present embodiment not only rotates in the rotational direction (direction toward the initial position when the throttle grip G is rotated in the positive direction α1) but also rotates the interlocking member 1. It is assumed that the force is applied in the axial direction β. Specifically, as shown in FIG. 9, the return spring 3 according to the present embodiment has a coil portion 3c in which a gap is created between adjacent windings, and is integrated with a holding member 4. In the state (unit Y shown in FIGS. 35 to 39), when it is housed in the case C as shown in FIGS. 29 and 31, the gap between the windings of the coil portion 3c is This causes the interlocking member 1 to be compressed in the axial direction β.

As a result, the interlocking member 1 is assembled with one end surface being pressed against the inner circumferential surface of the case C by the biasing force of the return spring 3 in the axial direction β. Therefore, when the throttle grip G is rotated, the interlocking member 1 rotates against the biasing force of the return spring 3 or the return spring 6 for reverse rotation, and one end surface of the interlocking member 1 contacts the inner peripheral surface of the case C. It will slide while being pressed.

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

Specifically, the magnetic sensor 2 according to the present embodiment is capable of detecting a rotational operation of the throttle grip G in the forward direction α1, and detects a rotational operation of the throttle grip G in the reverse direction α2 using the microswitch S. This microswitch S is electrically connected to electrical equipment mounted on the vehicle. When the microswitch S detects that the throttle grip G has rotated in the opposite direction α2 from the initial position, the detection signal is output, and the configuration is configured such that the electrical components mounted on the vehicle are activated or deactivated. has been done.

As a result, when the driver holds the throttle grip G and rotates it in the positive direction α1 from the initial position, the engine E can be controlled according to the rotation angle of the throttle grip G, and driving at any speed is possible. By rotating the throttle grip Gw in the reverse direction α2 from the initial position, it is possible to activate or deactivate electrical components installed in the vehicle (for example, a cruise control cancel function, etc.).

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 biased in the rotational direction toward the initial position by the return spring 3, and when the throttle grip G is rotated in the opposite direction α2 from the initial position, the throttle grip G is rotated in the opposite direction α2 from the initial position. Equipped with a return spring 6 for reverse rotation that biases G and the interlocking member 1 in the rotational direction toward the initial position, the throttle grip G can be rotated in the forward direction α1 and in 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, a return spring 3 is attached to the inner diameter side, and a return spring 6 for reverse rotation is attached to a portion on the outer diameter side from the attachment position of the return spring 3. Therefore, the return spring 3 and the return spring 6 for reverse rotation can be disposed in the radial direction of the interlocking member 1, and an increase in the width direction dimension can be suppressed.

Furthermore, the interlocking member 1 according to the second and third embodiments has the slide member 5 holding the return spring 6 for reverse rotation attached thereto, and when the throttle grip G is rotated in the reverse direction α2, the corresponding The slide member 5 moves relative to the interlocking member 1 and compresses the return spring 6 for reverse rotation, and the biasing force generated by the compression of the return spring 6 for reverse rotation is applied to the throttle grip G. The rotational force in the opposite direction α2 can be smoothly and reliably transmitted to the slide member 5, and the biasing force of the return spring 6 for reverse rotation 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 rotated in the opposite direction α2, the slide member 5 of the interlocking member 1 is rotated. Since the return spring 6 for reverse rotation can be compressed by moving in the circumferential direction, the slide member 5 and its movement range can be easily formed with respect to the interlocking member 1.

Further, the magnetic sensor 2 (rotation angle detection means) according to the second and third embodiments described above detects the rotation of the interlocking member 1 by detecting changes 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 composed of a sensor capable of detecting an angle and 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. This makes it possible to downsize the throttle grip device.

Further, according to the second embodiment, since the rotation 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 detection means), the rotation operation of the throttle grip G in the reverse direction α2 can be detected. It is possible to eliminate the need for a separate switch for detecting the rotational operation of the motor, and the number of parts can be reduced. 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 detection means), and the rotational operation of the throttle grip G in the reverse direction α2 can be detected. Since the microswitch S is provided, the rotational operation of the throttle grip G in the reverse direction α2 can be reliably detected by the microswitch S, and the operability at the time of starting the engine can be further improved.

In particular, according to the third embodiment, the microswitch S includes an actuating portion Sa that can be operated by protruding and retracting, and the interlocking member 1 has a protruding portion 1h having an inclined surface Q on one surface. and the microswitch S is attached so that the operating direction of the actuating part Sa is perpendicular to one surface of the protruding part 1h of the interlocking member 1, and when the interlocking member 1 rotates in the opposite direction α2, Since the actuating portion Sa is turned on by being pressed by the inclined surface Q, when the interlocking member 1 rotates in the opposite direction α2, the actuating portion Sa of the microswitch S can be pressed within an appropriate stroke range.

Although the present embodiment has been described above, the present invention is not limited thereto. For example, as shown in FIGS. 42 and 43, the interlocking member 1 It may be integrated with the material Gb). The interlocking member 1 is held by a holding member 4 and integrated with the return spring 3, as in the above embodiment. In this case, compared to a case where the interlocking member 1 is separate from the throttle grip G, the number of parts can be reduced, and the workability of assembling the throttle grip device can be improved.

Furthermore, 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, and not limited to non-contact type sensors but also contact type sensors, etc.) may be used. ) may also be used. Furthermore, instead of the magnet m, a magnet magnetized in the circumferential direction of the interlocking member 1 may be used. Note that the vehicle to which the present invention is applied is not limited to a two-wheeled vehicle as in this embodiment, and may be applied to other vehicles having a handlebar H (for example, an ATV or a snowmobile).
