It is for sending to the electronic control device, and as shown in FIGS. 1 urging means 5 , second urging means 6 , and resistance applying means 7 .

The case 1 is arranged in a housing case portion C (see FIGS. 1 and 2) attached to the tip side of the handlebar H of a motorcycle (vehicle) (base end side of the throttle grip G), and is used for the present throttle. It accommodates various parts that make up the grip device, and holds the interlocking member 2 and the rotating member 3 rotatably. Specifically, as shown in FIGS. 7 and 8, the case 1 according to the present embodiment is formed with a first accommodation recess 1a, a second accommodation recess 1b, and a third accommodation recess 1c. Reference numeral 8 denotes a lid member that covers the peripheral portion of the interlocking member 2 and the rotating member 3. As shown in FIG.

As shown in FIGS. 5 and 6, an interlocking member 2 and a rotating member 3 are rotatably assembled in the first accommodation recess 1a and the second accommodation recess 1b. As shown at 8 and 9, a plurality of springs s and resistance applying means 7 are assembled. The resistance applying means 7 is pressed against the surface f of the interlocking member 2 assembled in the first housing recess 1a by the biasing force of the spring s, and slides on the surface f when the interlocking member 2 rotates. It is designed to move and provide resistance.

The throttle grip G can be rotated while being gripped by the driver, and as shown in FIGS. A reverse rotation b of the direction is allowed. As shown in FIG. 15, a pair of engaging portions Ga are formed on the base end side of the throttle grip G, and these engaging portions Ga are engaged with the engaged portion 2a of the interlocking member 2 (see FIG. 15). 3 etc.), the throttle grip G and the interlocking member 2 are connected.

The interlocking member 2 has an engaged portion 2a that can be engaged with the engaging portion Ga formed on the throttle grip G, is connected to the throttle grip G, and rotates the throttle grip G forward and backward. It can rotate in conjunction with b. Specifically, as shown in FIGS. 12 to 14, the interlocking member 2 according to the present embodiment has an engaged portion 2a formed on one surface and a first biasing means 5 on the other surface. and an annular second accommodating portion 2d for accommodating the second urging means 6 are formed.

In addition, in the present embodiment, the second accommodating portion 2d is positioned radially outward from the first accommodating portion 2c, and the second biasing means 6 is arranged radially outward from the first biasing means 5. is set up. Furthermore, in the present embodiment, the first accommodating portion 2c and the second accommodating portion 2d are divided (defined) by the wall portion 2e integrally formed with the interlocking member 2, and the first biasing means 5 and the second The two biasing means 6 are configured to be securely held in the first accommodating portion 2c and the second accommodating portion 2d, respectively.

Further, a side surface of the interlocking member 2 is formed with a gear portion 2b that meshes with a gear formed on the outer peripheral surface of the rotating member 3. As shown in FIG. When the interlocking member 2 is rotated by rotating the throttle grip G, the rotational force is transmitted to the rotating member 3 via the gear portion 2b. The rotary member 3 can rotate in conjunction with the interlocking member 2, and when the interlocking member 2 rotates, it rotates about the axis Lb up to a rotation angle corresponding to the rotation angle. As shown in FIG. 6, a magnet m is attached to the rotating member 3, and the magnetic force generated from the magnet m changes as the rotating member 3 rotates.

As shown in FIG. 6, the magnetic sensor 4 (rotational angle detection means) is composed of a sensor arranged on the extension line of the axis Lb of the rotating member 3, and detects the magnetism generated by the magnet m attached to the rotating member 3. The rotation angle of the throttle grip G can be detected by detecting a change in . Specifically, the magnetic sensor 4 can obtain an output voltage corresponding to a change in the magnetic field of the magnet m (change in magnetic flux density). 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.

Thus, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates in the forward direction a, the rotating member 3 also rotates in conjunction with it, and the magnet m attached to the rotating member 3 also rotates with the rotating member 3. Rotate the same angle in the same direction. As a result, the magnetic field changes depending on the rotation angle, so that an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 2 (that is, the rotation angle of the throttle grip G) is detected based on the output voltage. It is possible to The rotation angle of the throttle grip G thus detected is transmitted as an electric signal to an 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 be controlled.

On the other hand, when the interlocking member rotates in the same direction as the throttle grip G reversely rotates b, the rotating member 3 also rotates in conjunction with it, and the magnet m attached to the rotating member 3 also rotates in the same direction. rotates by the same angle. As a result, since the magnetic field changes according to the rotation angle, an output voltage corresponding to the rotation angle can be obtained, and the reverse rotation b of the throttle grip G can be detected.

In this way, when the reverse rotation b of the throttle grip G is detected, a predetermined function of the two-wheeled vehicle can be activated or deactivated. This embodiment is applied to a two-wheeled vehicle equipped with a constant vehicle speed holding device (auto-cruise device) that holds the traveling speed constant, and the throttle grip G is rotated in reverse b (forward rotation a in which the throttle is fully opened from the initial position). ), the constant vehicle speed holding control can be stopped (cancelled).

The first biasing means 5 biases the interlocking member 2 and the throttle grip G toward their initial positions when the throttle grip G rotates forward (a). and the other end 5c. 8 and 14, the coil portion 5a of the first biasing means 5 is accommodated in the first accommodation portion 2c of the interlocking member 2, and the other end 5c is engaged with the locking portion 2g of the interlocking member 2. It is designed to be locked.

The second biasing means 6 biases the interlocking member 2 and the throttle grip G toward their initial positions when the throttle grip G rotates in the reverse direction b. As shown in FIG. and the other end 6c. As shown in FIGS. 8 and 14, the second urging means 6 has the coil portion 6a housed in the second housing portion 2d of the interlocking member 2, and the other end 6c of the interlocking member 2 at the engaging portion 2f ( Specifically, it is adapted to be locked to the other side surface 2fb) of the locking portion 2f.

In the present embodiment, the diameter (wire diameter) of the wire constituting the second biasing means 6 is larger than the diameter (wire diameter) of the wire constituting the first biasing means 5, and The number of turns of the coil portion 6a constituting the second biasing means 6 is smaller than the number of turns of the coil portion 6a constituting the first biasing means 5. As shown in FIG. Therefore, since the biasing force (stress) generated by the second biasing means 6 can be set to be greater than the biasing force (stress) generated by the first biasing means 5, the rotational operation of the throttle grip G with respect to the forward rotation a can be prevented. can be performed smoothly, and the unintentional reverse rotation b of the throttle grip G can be suppressed.

On the other hand, as shown in FIGS. 7 and 8, the case 1 according to the present embodiment has a locking portion 1e that locks one end 5b of the first biasing means 5 and one end 6b of the second biasing means 6. A locking portion 1d for stopping is formed. Accordingly, the locking portion 1e locks one end 5b of the first biasing means 5 against the direction of reverse rotation b while locking one end 5b of the first biasing means 5 against the direction of forward rotation a. While being in a non-locking (free) state, the locking portion 1d is in a non-locking (free) state to the one end 6b of the second urging means 6 in the direction of the forward rotation a, and in the direction of the reverse rotation b. One end 6b of the second urging means 6 is locked against.

In addition, the locking portion 2f of the interlocking member 2 according to the present embodiment is formed integrally with the interlocking member 2 and is formed of a projecting portion having one side surface 2fa and the other side surface 2fb. When the rotation a is performed, one side surface 2fa of the locking portion 2f presses the one end 6b of the second biasing means 6 locked by the locking portion 1d so that the one end 6b follows the rotation of the interlocking member 2. When the interlocking member 2 rotates in the reverse direction b, the other end 6c of the second biasing means 6 locked to the other side surface 2fb of the locking portion 2f follows the rotation of the interlocking member 2. As shown in FIG.

As a result, when the throttle grip G rotates forward (a), one end 5b of the first biasing means 5 is locked to the locking portion 1e and fixed to the case 1, while the other end 5c is locked to the locking portion 2g. Since the coil portion 5a is twisted to follow the rotation of the interlocking member 2, the interlocking member 2 and the throttle grip G are urged toward the initial positions. On the other hand, when the throttle grip G reversely rotates b, the other end 5c of the first biasing means 5 follows the rotation of the interlocking member 2 with the other end 5c being locked by the locking portion 2g, but the one end 5b is in a free state ( Since the coil portion 5a is not locked, the coil portion 5a is rotated together with the interlocking member 2 without being twisted, and no urging force is generated.

Further, when the throttle grip G reversely rotates b, one end 6b of the second urging means 6 is locked to the locking portion 1d to be fixed to the case 1, and the other end 6c of the second biasing means 6 is locked to the other side of the locking portion 2f. Since it is pressed by 2fb and follows the rotation of the interlocking member 2, the coil portion 6a is twisted and urges the interlocking member 2 and the throttle grip G toward the initial positions. On the other hand, one end 6b of the second biasing means 6 is pressed by one side surface 2fa of the locking portion 2f when the throttle grip G rotates in the forward direction (a) to release the locking by the locking portion 1d of the case 1. Since the rotation of the interlocking member 2 is followed and the engagement of the other end 6c with respect to the other side surface 2fb of the engaging portion 2f is maintained, the coil portion 5b is not twisted (the second biasing means 6) and the interlocking member 2 so that no biasing force is generated.

Here, the first urging means 5 and the second urging means 6 according to this embodiment are composed of torsion coil springs as described above, and as shown in FIGS. and the coil portions (5a, 6a) of the second biasing means 6 are arranged on a coaxial circle (on a concentric circle with the axis La as a common center) while overlapping in the direction of the axis La of the interlocking member 2. . That is, the first urging means 5 is accommodated in the first accommodating portion 2c located on the inner diameter side of the interlocking member 2, and the second urging means 6 is accommodated in the second accommodating portion 2d located on the outer diameter side of the interlocking member.

Further, the interlocking member 2 according to the present embodiment includes an annular first accommodating portion 2c that accommodates the first biasing means 5 and an annular second accommodating portion 2d that accommodates the second biasing means 6. Since the first accommodating portion 2c and the second accommodating portion 2d are separated by the wall portion 2e formed integrally with the interlocking member 2, the first urging means 5 and the second urging means 6 can be accurately positioned. can be assembled.

Furthermore, since the rotating member 3 that can rotate in conjunction with the interlocking member 2 is provided, and the interlocking member 2 is formed with the gear portion 2b for transmitting the rotational force of the throttle grip G to the rotating member 3, The interlocking member 2 can have both the function of accommodating the first biasing means 5 and the second biasing means 6 and the function of transmitting the rotational force to the rotating member 3 .

In particular, the second biasing means 6 according to this embodiment, when the throttle grip G reversely rotates b, the coil portion 6a is twisted to bias the interlocking member 2 and the throttle grip G toward the initial position, and the throttle grip G rotates. When the grip G rotates in the forward direction (a), the coil portion 6a is not twisted and rotates together with the interlocking member 2, thereby reliably preventing the biasing force from being generated by the second biasing means 6 when the throttle grip G rotates in the forward direction (a). can do.

In particular, the second biasing means 6 according to the present embodiment, when the throttle grip G reversely rotates b, twists the coil portion 6a to bias the interlocking member 10 and the throttle grip G toward the initial position, When the grip G rotates in the forward direction (a), the coil portion 6a is not twisted and is maintained in a stationary state. can be prevented.

Although the present embodiment has been described above, the present invention is not limited to this. The rotation angle may be detected, in which case the rotation member 3 can be eliminated. In addition, in the present embodiment, the second biasing means 6 is disposed radially outward from the first biasing means 5, but the second biasing means 6 is radially inner than the first biasing means 5. It may be arranged.

Furthermore, in the present embodiment, when the throttle grip G is rotated in reverse, the constant vehicle speed holding control of the constant vehicle speed holding device (auto-cruise device) is stopped (cancelled). It suffices if a predetermined function of the vehicle is activated or deactivated upon detection of direction rotation. For example, by rotating the throttle grip G in the reverse direction, authentication may be started in an immobilizer system or smart entry system, a starter for starting the engine, or an emergency lighting means such as a hazard may be activated. The applicable vehicle is not limited to a two-wheeled vehicle as in the present embodiment, and may be applied to other vehicles having a handlebar H (for example, an ATV, a snowmobile, etc.).

The first urging means and the second urging means are composed of torsion coil springs, and the coil portions of the first urging means and the second urging means overlap in the axial direction of the interlocking member and extend coaxially. The second biasing means is arranged to bias the interlocking member and the throttle grip toward the initial position by twisting the coil portion when the throttle grip rotates in the reverse direction, and when the throttle grip rotates in the forward direction. Also, as long as the coil portion is not twisted and rotates together with the interlocking member, it can be applied to a throttle grip device having a different external shape or having other functions added thereto.
