It is for transmission, and as shown in FIGS. , a magnetic sensor 7 (rotation angle detection means) and a printed circuit board 8 .

The case 1 is arranged in a cover member C (see FIGS. 1 to 3) attached to the tip side of the handlebar H (base end side of the throttle grip G) of a motorcycle (vehicle), and the present throttle grip. It accommodates various parts that make up the device, and also holds the interlocking member 2, the rotating member 6, and the like so as to be rotatable. As shown in FIG. 10, the case 1 is made of a molded component in which a first recess A for rotatably accommodating the interlocking member 2 and a second recess B for rotatably accommodating the rotating member 6 are formed. Reference numeral 5 denotes a lid member for covering the opening side of the case 1. As shown in FIG.

As shown in FIGS. 2 and 3, the cover member C is constructed by assembling an upper half-split member C1 and a lower half-split member C2 together to form the present throttle grip device therein. A notch C2a (see FIG. 3) is formed in the lower half member C2 so as to accommodate various parts. A fixing portion ha and a ridge portion hb (see FIG. 5) integrally formed with the case 1 are fitted into the notch C2a to be assembled.

The throttle grip G extends from the cover member C and is attached to the tip of the handlebar H of the vehicle so that it can be rotated while being gripped by the driver. An engaging portion Ga (see FIG. 9) consisting of a concave portion is formed on the base end side of the throttle grip G, and this engaging portion Ga is the engaged portion 2a of the interlocking member 2 (FIGS. 4, 5 and 5). 6, 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, and can rotate in conjunction with the rotation of the throttle grip G. As shown in FIG. Specifically, as shown in FIG. 11, the interlocking member 2 according to the present embodiment is formed by connecting an engaged portion 2a, an accommodation groove 2b, a flange 2c, a gear 2d, and an accommodation groove 2b. An annular member having an engaging portion 2e and an insertion hole 2f through which the handlebar H can be inserted. In this embodiment, the interlocking member 2 is formed with a sliding surface n1, 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 of the throttle grip G. A base end side of a throttle grip G is connected to the member 2 . As a result, the interlocking member 2 can also rotate as the throttle grip G rotates. The engaged portion 2a is formed on the surface of the interlocking member 2 (one surface that can be exposed to the outside when assembled to the case 1, as shown in FIG. 4), and the other surface of the interlocking member 2. As shown in FIG. 11, the surface is formed with a housing groove 2b, a locking portion 2e, and a sliding surface n1.

The accommodating groove 2 b is formed in the other surface of the interlocking member 2 in a circumferential direction (rotational direction) of the interlocking member 2 , and is configured to accommodate the return spring 4 . A flange 2c is formed in the interlocking member 2 along the circumferential direction, and a gear 2d is formed over a predetermined range. As shown in FIG. 6, this gear 2d is assembled so as to mesh with a gear formed on the outer periphery of the rotating member 6, so that the rotating member 6 rotates as the interlocking member 2 rotates. .

The rotating member 6 can rotate in conjunction with the rotation of the interlocking member 2 as described above, is housed in the second recess B of the case 1, and rotates about the axis L1 (see FIGS. 6 to 8). It is rotatable as Thus, 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 is changed as the rotating member 6 rotates. 7 and 8, reference numeral a indicates a torsion coil spring that biases the rotating member 6 toward the interlocking member 2 side.

As shown in FIG. 8, the magnetic sensor 7 (rotational angle detection means) is composed of a sensor arranged at a position on the extension line of the axis L1 of the rotating member 6, and the magnetism generated by the magnet m attached to the rotating member 6 is (change in the direction of the magnetic field), the rotation angle of the throttle grip G can be detected. Specifically, the magnetic sensor 7 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. The magnetic sensor 7 according to this embodiment is attached to a printed circuit board 8 on which a predetermined electric circuit is formed by printing.

When the interlocking member 2 rotates in the same direction as the throttle grip G rotates, the rotating member 6 also rotates in accordance with the gear ratio (the gear ratio between the interlocking member 2 and the rotating member 6). The magnet m attached to the rotating member 6 also rotates by the same angle. 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.

That is, the return spring 4 is assembled with one end 4a attached to the interlocking member 2 and the other end 4b attached to the case 1. When the throttle grip G is rotated, the biasing force of the return spring 4 is applied. Since the interlocking member 2 rotates against it, the urging force is transmitted to the throttle grip G, and a force acts to return the throttle grip G and the interlocking member 2 to their initial positions.

11 and 13, the locking portion 2e that locks the one end 4a of the return spring 4 is located on the inner diameter side of the housing groove 2b of the interlocking member 2 (the center of the housing groove 2b with respect to the center of the interlocking member 2). position inside the formation position). That is, the accommodation groove 2b according to the present embodiment is formed on the outer diameter side of the engaged portion 2a of the interlocking member 2 (position outside the position where the engaged portion 2a is formed with respect to the center of the interlocking member 2). Therefore, the locking portion 2e can be formed by utilizing the space generated inside the housing groove 2b (the space on the surface opposite to the surface on which the engaged portion 2e is formed). .

Here, as shown in FIGS. 7 and 12, the return spring 4 according to the present embodiment has at least a part of the coil portion 4c accommodated in the accommodation groove 2b and is rotated in the rotation axis direction of the interlocking member 2 (left and right in the figure). direction) offset within dimension α (overlapping dimension t within dimension α). The dimension α in this case indicates the width dimension of the interlocking member 2 and is the dimension of the surface extending in the same direction as the thickness dimension β of the case 1 . In the return spring 4 according to the present embodiment, part of the coil portion 4c is offset by the dimension t within the dimension α of the interlocking member 2 in the rotation axis direction. The interlocking member 2 may be assembled with an offset within the dimension α in the rotation axis direction.

As a result, the torsion coil spring that constitutes the return spring 4 has a coil portion 4c with a large diameter. can do.

That is, when the diameter of the coil portion 4c of the return spring 4 is large as in the present embodiment, the spring constant becomes small and the biasing force becomes small. can be widened, and by reducing the number of turns of the coil portion 4c, the upper limit side of the urging force (set spring load) that can be set can be widened. Thus, the adjustment range of the biasing force of the return spring 4 (the range of spring load that can be set) can be widened, and the degree of freedom in setting the spring load can be improved.
