It is composed of a molded part in which a recess 1c for accommodating (see 13) and a fitting recess 1d for fitting a protrusion 3a (see FIG. 13) of the resistance means 3 are formed. Reference numeral 9 indicates a lid member for closing the opening side of the case 1.

The throttle grip G extends from the cover member S and can be rotated while being gripped by the driver, and can be rotated in a predetermined direction around the axis from the initial position. As shown in FIG. 2, the base end portion of the throttle grip G has an engaging portion Ga having a pair of groove shapes, a flange portion Gb protruding in the radial direction, and a pressed portion formed on the flange portion Gb. Gba is formed, and the engaging portion Ga engages with the engaged portion 2a (see FIGS. 3, 4, 9, 10, etc.) of the interlocking member 2 in the rotational direction, thereby engaging with the throttle grip G. The interlocking member 2 is connected to the interlocking member 2.

More specifically, as shown in FIG. 2, the collar portion Gb according to the present embodiment is composed of a portion integrally protruding from the side surface of the base end portion of the throttle grip G in the radial direction. A pressed portion Gba that comes into contact with the tip 10aa of the pressing means 10 and receives a pressing force is formed on a part (end portion). The thickness dimension (dimension of the handle grip G with respect to the axial direction) of the pressed portion Gba is set to be larger than that of other portions of the collar portion Gb, and the pressed portion Gba can be reliably contacted with the tip 10aa of the pressing means 10. ..

The interlocking member 2 has an engaged portion 2a that can engage with the engaging portion Ga formed on the throttle grip G, and can rotate in the case 1 in conjunction with the rotation operation of the throttle grip G. is there. Specifically, as shown in FIGS. 9 and 10, the interlocking member 2 according to the present embodiment includes the engaged portion 2a, the accommodating portion 2b, the accommodating portion 2c, the gear 2d, and the engaging groove 2e. It is composed of an annular member having. In the present embodiment, the interlocking member 2 is formed with a sliding surface N, which will be described in detail later.

The engaged portion 2a has a convex shape formed at a position corresponding to the engaging portion Ga (groove shape) of the throttle grip G, and the engaged portion 2a is fitted into and engaged with the engaging portion Ga. In this state, the base end side of the throttle grip G is connected to the interlocking member 2. As a result, the interlocking member 2 can also rotate with the rotation of the throttle grip G. The engaged portion 2a is formed on the surface of the interlocking member 2 (one surface that can be faced to the outside as shown in FIGS. 3 and 4 when assembled to the case 1) and is formed on the other surface. Is formed with a housing portion 2b.

Further, as shown in FIGS. 9 and 10, the engaged portion 2a of the interlocking member 2 has a wall surface 2aa and a wall surface 2ab with respect to the rotation direction of the interlocking member 2, and the wall surface 2aa and the wall surface 2ab have a wall surface 2aa. The engaging portion Ga can be fitted. Then, when the throttle grip G rotates from the initial position, the engaging portion Ga presses the wall surface 2ab to rotate the interlocking member 2 in the same direction, and when the force of the hand holding the throttle grip G is relaxed, the interlocking member 2 moves. The urging force of the urging means 4 causes the throttle grip G to rotate toward the initial position, and the throttle grip G returns to the initial position while maintaining the state in which the engaging portion Ga is in contact with the wall surface 2ab.

The accommodating portion 2b has a groove shape formed in an arc shape toward the circumferential direction of the interlocking member 2, and the pressing means 10 described in detail later can be accommodated therein. Further, the accommodating portion 2b has a concave shape formed on the back surface of the interlocking member 2, and is communicated with the front surface side of the interlocking member 2 via the insertion hole 2ba. The tip 10aa side of the pressing means 10, which will be described later, is inserted into the insertion hole 2ba so that it can freely appear and disappear with respect to the surface side of the interlocking member 2.

Further, the interlocking member 2 according to the present embodiment has an accommodating portion 2c formed in an annular shape on the back surface side thereof, and as shown in FIGS. 5 to 7, the accommodating portion 2c is urged by the urging means 4 It is said that a part of the can be accommodated. Further, a gear 2d is formed on the interlocking member 2 over a predetermined range, and as shown in FIGS. 14 and 15, the gear 2d is assembled in a state of being meshed with a gear formed on the outer periphery of the rotating member 6. The rotating member 6 rotates as the interlocking member 2 rotates.

The rotating member 6 can rotate in conjunction with the interlocking member 2 as described above, is housed in the accommodating portion 1a of the case 1, and is rotatable about the axis L (see FIGS. 5, 14 and 15). It is said that. Therefore, when the interlocking member 2 rotates, the rotating member 6 rotates at a rotation angle corresponding to the rotation angle. A magnet m is attached to the rotating member 6, and the direction of the magnetic field generated from the magnet m changes with the rotation of the rotating member 6.

As shown in FIG. 5, the magnetic sensor 7 (rotation angle detecting means) includes a sensor arranged at a position on an extension line of the axis L of the rotating member 6, and magnetism generated from a magnet m attached to the rotating member 6. The rotation angle of the throttle grip G can be detected by detecting the change (change in the direction of the magnetic field). Specifically, the magnetic sensor 7 can obtain an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet m. For example, a Hall element (specifically, a Hall element) which is a magnetic sensor utilizing the Hall effect. Is composed of a linear Hall IC) or the like that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnet m. The magnetic sensor 7 according to the present embodiment is formed on a printed circuit board 8 on which a predetermined electric circuit is printed.

Then, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates, the rotating member 6 also interlocks and rotates according to the gear ratio (the gear ratio of the interlocking member 2 and the rotating member 6). The magnet m attached to the rotating member 6 also rotates in the same direction by the same angle. As a result, since the magnetic field changes depending on the rotation angle, 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 do. The rotation angle of the throttle grip G detected in this way is transmitted as an electric signal to the ECU (engine control unit) mounted on the motorcycle, and the rotation angle of the throttle grip G is transmitted according to the rotation angle of the vehicle. The engine can be controlled.

The urging means 4 is composed of a torsion coil spring, and is a return spring for urging the interlocking member 2 toward the initial position when the throttle grip G rotates. That is, one end 4b of the urging means 4 is locked in the engaging groove 2e of the interlocking member 2, and the other end 4a is locked in the engaging groove 1e (see FIGS. 14 and 15) of the case 1. When the throttle grip G is rotated, the interlocking member 2 rotates against the urging force of the urging means 4, so that the urging force is transmitted to the throttle grip G and the force to return the throttle grip G to the initial position. Works.

The resistance means 3 can generate a resistance force when the throttle grip G rotates to generate a rotational load. As shown in FIG. 13, the resistance means 3 is formed on a sliding surface N formed over the circumferential direction of the interlocking member 2. On the other hand, it is composed of an annular friction member assembled in a contact state. The resistance means 3 is assembled by pressing the protrusion 3a against the sliding surface N of the interlocking member 2 by the urging force of the spring s while fitting the protrusion 3a into the fitting recess 1d of the case 1. When 2 rotates, it slides on the sliding surface N to generate a frictional force, and a desired rotational load can be generated.

Then, the case 1 in which the necessary parts are assembled constitutes the unit 5 as shown in FIGS. 3 and 4, and is fixed in the cover member S with screws or the like as shown in FIGS. 5 to 7. It is housed while being housed. The cover member S can be fixed to the handlebar H of the vehicle while accommodating the case 1 (unit 5), and as shown in FIGS. 5 to 7 and 11, the base end portion of the throttle grip G is inserted. An opening Sa to be inserted, a positioning protrusion whose tip abuts and supports the handlebar H, and an opening Sc through which the handlebar H is inserted are formed.

The flange portion Gb according to the present embodiment interferes with the inner edge portion of the opening Sa so that the base end portion of the throttle grip G can be prevented from coming off from the opening Sa. That is, when the throttle grip G is engaged with the interlocking member 2 assembled to the case 1 in the cover member S, as shown in FIG. 7, the flange portion Gb formed at the base end portion of the throttle grip G becomes the cover member. Since it is located at the inner edge of the opening Sa of S, the flange Gb interferes with the inner edge of the opening Sa even if a pulling load is applied to the throttle grip G on the right side in the figure. It is possible to prevent it from coming off.

Here, in the present embodiment, when the throttle grip G is in the initial position, the pressing means that can press the pressed portion Gba formed on the flange portion Gb to press the engaging portion Ga against the engaged portion 2a. It is provided with 10. As shown in FIG. 12, the pressing means 10 urges the contact portion 10a capable of contacting the pressed portion Gba of the throttle grip G and the contact portion 10a to press the engaging portion Ga against the engaged portion 2a. It is configured to include an urging means 10b that can be made to be urged, a contact portion 10a and an urging means 10b, and a storage case 10c that is attached to the housing portion 2b of the interlocking member 2 and is formed on the interlocking member 2. It is housed in the storage section 2b.

As shown in FIG. 12, the contact portion 10a is composed of a pin-shaped member, and its tip 10aa (a portion in contact with the pressed portion Gba) is formed to form a spherical surface, and an insertion formed in the interlocking member 2 is formed. It is assembled by inserting it through the hole 2ba (see FIG. 3). That is, the insertion hole 2ba is composed of a hole for communicating the accommodating portion 2b formed on the back surface side of the interlocking member 2 and the front surface side of the interlocking member 2, and when the pressing means 10 is accommodated in the accommodating portion 2b, it comes into contact. The tip 10aa side of the portion 10a is located on the surface side of the interlocking member 2 through the insertion hole 2ba, and the tip 10aa is configured to be able to come into contact with the pressed portion Gba.

A spring receiving portion 10ab is integrally formed on the side of the contact portion 10a opposite to the tip 10aa. The spring receiving portion 10ba is composed of a portion that receives the urging force of the urging means 10b housed in the housing case 10c and transmits the urging force to the pressed portion Gba that comes into contact with the tip 10aa to press the spring receiving portion 10ba. The urging means 10b is composed of a coil spring whose one end is in contact with the spring receiving portion 10ab and assembled, and is accommodated in the accommodating case 10c, and the contact portion 10a can be urged in the rotational direction of the interlocking member 2. It has become.

As a result, the pressing means 10 presses against the pressed portion Gba in the rotation direction of the throttle grip G. Further, the contact portion 10a urged by the urging means 10b urges the pressed portion Gba in the rotation direction of the interlocking member 2, so that the pressed portion Gba is pressed in the same direction, thereby causing the throttle grip. The engaging portion Ga of G is pressed against the wall surface 2ab of the engaged portion 2a. As a result, the pressing means 10 according to the present embodiment presses the throttle grip G at the initial position toward the interlocking member 2 and the rotation side of the throttle grip G.

Then, when the throttle grip G is in the initial position, as shown in FIG. 14, the contact portion 10a is in contact with the pressed portion Gb, and the pressed portion Gb is moved to the interlocking member 2 by the urging force of the urging means 10b. Since it is pressed toward the rotation direction (rotation side in the a direction in the figure), the engaging portion Ga is pressed against the wall surface 2ab of the engaged portion 2a and is positioned. As a result, it is possible to eliminate the gap between the engaging portion Ga of the throttle grip G and the engaged portion 2a (wall surface 2ab) of the interlocking member 2 and eliminate the play between the two members.

Further, when the throttle grip G is rotated from the initial position (rotation in the a direction in FIG. 14), as shown in FIG. 15, the engaging portion Ga presses the wall surface 2ab of the engaged portion 2a to press the interlocking member 2. While rotating in the same direction, the contact between the tip 10aa of the contact portion 10a and the pressed portion Gb is maintained. When the force of the hand holding the throttle grip G is relaxed, the interlocking member 2 is rotated toward the initial position by the urging force of the urging means 4, and the engaging portion Ga is maintained in contact with the wall surface 2ab. While doing so, the throttle grip G returns to the initial position.

According to the present embodiment, it is formed on the flange portion Gb formed at the base end portion of the throttle grip G and protruding in the radial direction, and formed on the interlocking member 2 and formed on the flange portion Gb when the throttle grip G is in the initial position. Since the pressing means 10 capable of pressing the pressed portion Gba to press the engaged portion Ga against the engaged portion 2a is provided, the throttle grip G and the interlocking member 2 are separated from each other to replace the throttle grip G. While facilitating, it is possible to suppress backlash between the throttle grip G and the interlocking member 2.

In particular, in the present embodiment, since the pressing means 10 presses the pressed portion Gba formed on the flange portion Gb of the throttle grip G to suppress backlash, the pressing means 10 presses the engaging portion 2a. Compared with the one, the pressing force on the throttle grip G can be efficiently applied, and the degree of freedom in design can be improved by making the size and shape of the flange portion Gb arbitrary. Further, in the present embodiment, since the pressing means 10 presses the pressed portion Gba formed on the flange portion Gb of the throttle grip G to suppress backlash, the unit 5 can be made thinner.

Further, it is assumed that the cover member S is provided so as to be able to be fixed to the handlebar H of the vehicle while accommodating the case 1 and to have an opening Sa through which the base end portion of the throttle grip G is inserted. Is able to prevent the base end portion of the throttle grip G from coming off from the opening Sa by interfering with the inner edge portion of the opening S, so that the flange portion Gb causes backlash between the throttle grip G and the interlocking member 2. It can have both a function of suppressing the cover member S and a function of preventing the cover member S from coming off from the opening Sa.

Further, since the thickness of the pressed portion Gba according to the present embodiment is set to be larger than that of other portions of the flange portion Gb, the pressing force by the pressing means 10 can be reliably received, and the pressure is interlocked with the throttle grip G. The backlash between the member 2 and the member 2 can be suppressed more reliably and stably. Further, since the pressing means 10 according to the present embodiment presses the pressed portion Gba in the rotation direction of the throttle grip G (interlocking member 2), when the throttle grip G is rotated, the interlocking member 2 is pressed. It rotates without idling, and the driver can operate the throttle grip G without any discomfort.

In addition, the pressing means 10 according to the present embodiment has a contact portion 10a capable of contacting the pressed portion Gba of the throttle grip G and an urging means 10b capable of urging the contact portion 10a to press the pressed portion Gba. Therefore, the urging force of the urging means 10b can provide mechanical play of the throttle grip G, and the throttle grip G can be smoothly attached to and detached from the interlocking member 2 to replace the throttle grip G. It can be done easily.

In particular, in the contact portion 10a according to the present embodiment, at least the portion in contact with the pressed portion Gba forms a spherical surface, so that the contact portion 10a can be point-contacted with the pressed portion Gba and with respect to the pressed portion Gba. The contact portion 10a can be pressed stably, and the throttle grip G can be more smoothly attached to and detached from the interlocking member 2. The contact portion 10a according to the present embodiment has a tip 10aa (that is, a portion in contact with the pressed portion Gba) forming a spherical surface, but may have another shape.

Although the present embodiment has been described above, the present invention is not limited to this, and for example, the urging means 10b in the pressing means 10 may be another urging means different from the coil spring. Further, the urging means 4 may be another general-purpose elastic body (spring of another form such as a coil spring or a leaf spring, or resin, rubber, or the like). Further, although the throttle grip according to the present embodiment can be rotated only in one direction from the initial position, it may be rotated from the initial position to forward rotation and reverse rotation.

Further, the flange portion Gb according to the present embodiment interferes with the inner edge portion of the opening Sa in the cover member S, and the base end portion of the throttle grip G can be prevented from coming off from the opening Sa. It may be a non-functional part. Further, instead of the magnetic sensor 7, another sensor (such as a sensor that does not use magnetism) that can detect the rotation angle of the throttle grip G may be used. The vehicle to be applied 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, ATV, snowmobile, etc.).

A flange formed at the base end of the throttle grip and protruding in the radial direction, and an interlocking member formed on the interlocking member. When the throttle grip is in the initial position, the pressed portion formed on the flange is pressed to engage the engaging portion. As long as it is a throttle grip device provided with a pressing means capable of pressing the engaged portion, it can be applied to a device having a different appearance shape or a device to which other functions are added.
