The Hall IC element 8 is composed of a sensor capable of detecting whether the clutch lever 2 is at the initial position, and is turned off electrically by the magnetic force of the magnet M when the clutch lever 2 is at the initial position. When the clutch lever 2 is in the swing position, it is electrically turned on, and the clutch lever 2 in the initial position can be detected. In this way, the magnetic sensor 7 and the Hall IC element 8 according to this embodiment are attached to the common substrate 6.

The first biasing means 9 and the second biasing means 10 bias the clutch lever 2 toward the initial position, and as shown in FIGS. Each of the springs is made of a torsion coil spring having a coil portion c at each end thereof, and the coil portion c is inserted into the swing shaft La via a locking member 4 and attached to the swing shaft La. Specifically, the first biasing means 9 is attached to the first locking member 4a by inserting the coil portion c, one end a of which is locked to the locking portion 4aa, and the second The biasing means 10 is attached to the second locking member 4b by inserting the coil portion c therethrough, and one end portion a thereof is locked to the locking portion 4ba. That is, as shown in FIGS. 3 and 4, the first biasing means 9 is attached to one end of the swing shaft La, and the second biasing means 10 is attached to the other end of the swing shaft La. The clutch levers 2 and 2 can each apply biasing forces to the clutch levers 2 via the swing shafts La.

Here, the first biasing means 9 according to the present embodiment is assembled so as to generate a biasing force during the process of the clutch lever 2 rocking from the initial position (immediately after the start of rocking), and the second biasing means 10 is assembled so as to generate an urging force in the process of further swinging of the clutch lever 2 from the swinging position where the clutch lever 2 has been swinged by a predetermined angle. That is, as shown in FIG. 11, during the entire process in which the clutch lever 2 swings from the initial position, the biasing force by the first biasing means 9 is applied to the clutch lever 2, and the clutch lever 2 swings by a predetermined angle α. After that, in addition to the urging force by the first urging means 9, the urging force by the second urging means 10 is applied.

The second biasing means 10 applies a biasing force when the clutch lever 2 swings from the initial position. 10, the other end b is spaced apart from the second contact portion 3ab formed on the holder portion 3 (first holder portion 3a) by a distance t, and the clutch lever 2 is When the clutch lever 2 swings to a swinging position (a position that has been swung by a predetermined angle), the other end b comes into contact with the second contact portion 3ab, and a biasing force is applied as the clutch lever 2 further swings from the swinging position. is configured to do so.

As a result, as shown in FIG. 11, until the clutch lever 2 is swung from the initial position to the predetermined angle α, the energizing force of the first energizing means 9 is applied to the clutch lever 2 via the oscillating shaft La. This makes it possible to reproduce the operation resistance due to the play of the operation wire in a conventional clutch device operated by an operation wire, and when the clutch lever 2 is further swung from the predetermined angle α, the first biasing means 9 The biasing forces of both the second biasing means 10 and the second biasing means 10 are applied to the clutch lever 2 via the swing shaft La, and it is possible to reproduce the operating resistance of operating the clutch using a conventional operating wire.

In this embodiment, the biasing forces of the first biasing means 9 and the second biasing means 10 are approximately the same, but different biasing forces may be used, for example, depending on the number of turns of the torsion coil spring, the diameter of the wire, etc. It may be something that can be given. Furthermore, in this embodiment, although the configuration includes two urging means, the first urging means 9 and the second urging means 10, in addition to these urging means, other urging means may be used. (In other words, it may be equipped with three or more plurality of biasing means).

According to the present embodiment, the clutch lever 2 is provided with a plurality of (two in this embodiment) biasing means that bias the clutch lever 2 toward the initial position, and the plurality of biasing means include at least the clutch lever 2. A first biasing means 9 generates a biasing force when the clutch lever 2 swings from the initial position, and a second biasing means 9 generates a biasing force when the clutch lever 2 further swings from the swinging position where the clutch lever 2 swings by a predetermined angle. Since the clutch device includes the force means 10, it is possible to reproduce the operational feeling when operating the clutch device with the operating wire, and it is possible to suppress the discomfort during operation and improve the operability.

Further, the first biasing means 9 and the second biasing means 10 according to the present embodiment are each made of a torsion coil spring having a coil portion c between one end a and the other end b, and the coil portion c Since the clutch lever device 1 is inserted into the swing shaft La and attached to the clutch lever device 1, the clutch lever device 1 can be further downsized.

Furthermore, locking portions (4aa, 4ba ), the first biasing means 9 and the second biasing means 10 can be stably and reliably attached to the swing shaft La. Moreover, the swing shaft La, the locking member 4, the first biasing means 9, and the second biasing means 10 can be integrated to improve ease of assembly.

Furthermore, the locking member 4 according to the present embodiment has a magnet M attached thereto, and the angle detection means (magnetic sensor 7) detects the swing angle of the clutch lever 2 by detecting a change in the magnetic force from the magnet M. Therefore, in addition to the first biasing means 9 and the second biasing means 10, the locking member 4 includes a magnet M that allows the angle detection means (magnetic sensor 7) to detect changes in magnetic force. These parts can be integrated to improve ease of assembly.

In addition, when the clutch lever 2 is in the initial position, the first biasing means 9 is brought into a state in which the other end b is in contact with the first contact part 3aa formed in the holder part 3, and the clutch lever 2 The second biasing means 10 applies a biasing force during the process of swinging from the initial position, and the second biasing means 10 has the other end b formed in the holder part 3 when the clutch lever 2 is in the initial position. When the clutch lever 2 swings to the swinging position, the other end b contacts the second contacting part 3ab, and the clutch lever 2 further moves from the swinging position. Since the biasing force is applied during the swinging process, the operational feeling when operating the clutch device using the operating wire can be reproduced with a simple configuration.

In addition, since the Hall IC element 8 (initial position detection means) capable of detecting whether or not the clutch lever 2 is at the initial position is provided, the detection result of the Hall IC element 8 (initial position detection means) and the magnetic sensor 7 (angle By monitoring together with the detection results of the detection means), defects such as failures can be detected early, and safety can be improved. For example, if the Hall IC element 8 (initial position detection means) indicates that the clutch lever 2 is not at the initial position, but the magnetic sensor 7 (angle detection means) does not detect the swing angle, it may be determined that there is a malfunction such as a malfunction. In addition, safety can be improved by allowing the vehicle engine to start on the condition that the Hall IC element 8 (initial position detection means) detects that the clutch lever 2 is not in the initial position.

Furthermore, since the magnetic sensor 7 (angle detection means) and the Hall IC element 8 (initial position detection means) according to the present embodiment are attached to the common substrate 6, compared to the case where they are attached to separate substrates, The number of parts can be reduced and maintenance can be facilitated. Note that the magnetic sensor 7 (angle detection means) and the Hall IC element 8 (initial position detection means) may be attached to separate substrates, respectively.

The magnetic sensor 7 (angle detection means) detects the rotation angle of the rotating member 12 to detect the rotation of the clutch lever 2. Since the movement angle can be detected and the first biasing means 9 and the second biasing means 10 are housed in the case member 14 while being attached to the rotating member 12, a conventional clutch lever can be used. In addition, it is possible to reproduce the operational feeling when operating the clutch device using the operating wire, and it is possible to suppress the discomfort during operation and improve the operability.

Further, the first biasing means 9 and the second biasing means 10 according to the present embodiment are each made of a torsion coil spring having a coil portion c between one end a and the other end b, and the coil portion c Since the mounting member 11 is inserted into the rotating member 12 (specifically, the annular protrusion 12ac of the first rotating member 12a) and attached to the mounting member 11, the mounting member 11 can be made smaller.

Furthermore, the rotating member 12 according to the present embodiment includes a first rotating member 12a connected to the tip Wb of the operating wire W, and a state in which the first rotating member 12a is rotated by a predetermined angle. The first biasing means 9 is attached to the first rotating member 12a and applies a biasing force as the first rotating member 12a rotates. Since the second biasing means 10 is attached to the second rotating member 12b and applies a biasing force as the second rotating member 12b rotates, the operational feeling when operating the clutch device with the operating wire is simplified. It can be reproduced with.

In addition, a magnet M is attached to the first rotating member 12a according to the present embodiment via an interlocking member 13, and the magnetic sensor 7 (angle detection means) detects changes in magnetic force from the magnet M. Since the swing angle of the clutch lever 2 can be detected, the rotation angle of the first rotating member 12a can be detected with high precision, and the swing angle of the clutch lever 2 can be detected with high precision.

Although the present embodiment has been described above, the present invention is not limited thereto, and the first biasing means 9 and the second biasing means 10 may be a biasing member of the same type (such as a coil spring) different from a torsion coil spring, Alternatively, different types of biasing members including torsion coil springs (coil springs, torsion coil springs, etc.) may be used. Further, the angle detection means according to the present embodiment is configured to detect the swing angle of the lever 2 by detecting changes in the magnetic force of the magnet M rotating together with the swing shaft La and the rotating member 12. Other types of detection sensors (including non-contact type and contact type) may be used. In this embodiment, the present invention is applied to a clutch lever of a two-wheeled vehicle, but it may be applied to other types of vehicles as long as it is provided on the tip side of a handlebar H included in the vehicle.

A plurality of biasing means are provided for biasing the clutch lever toward an initial position, and the plurality of biasing means include at least a first biasing unit that generates a biasing force in the process of swinging the clutch lever from the initial position. As long as the clutch lever device includes a biasing means and a second biasing means that generates a biasing force in the process of further rocking the clutch lever from the rocking position where the clutch lever has rocked at a predetermined angle, the clutch lever device may have a different external shape or a different shape.
