I have. That is, the locking portion 6e is composed of locking claws formed on both side surfaces of the base member 6, and when the base member 6 is inserted into the housing member 3, the locking portion 6e is in a bent state, and When reaching the position of the locking portion 3d, the locking portion 6e is restored and can be locked to the locked portion 3d. Note that the snap-fit is a type of mechanical joining means used for a joining portion of a metal, a resin, or the like, and refers to a joining mode in which the fitting is performed by fitting using the elasticity of a material.

  The magnetic sensor 4 (rotation angle detecting means) is composed of a sensor disposed at a position on the extension of the rotation axis of the interlocking member 1, and is mounted inside the handle pipe H and is attached to the interlocking member 1. The rotation angle of the interlocking member 1 and the throttle grip G can be detected by detecting a change in magnetism resulting from the rotation. Specifically, the magnetic sensor 4 can obtain an output voltage corresponding to a magnetic field change (change in magnetic flux density) of the magnetic member M, and is, for example, a Hall element (specifically, a magnetic sensor using the Hall effect). Are configured by a linear Hall IC that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnetic member M.

  The magnetic member M is a member that generates magnetism, is attached to the interlocking member 1, and is rotatable with the interlocking member 1. The magnetic member M according to the present embodiment is held by the holding member 8 and attached to the attachment portion 1d of the interlocking member 1 via the holding member 8. More specifically, as shown in FIGS. 27 and 28, the magnetic member M is formed of a cylindrical resin component having at least a distal end magnetized, and has an insertion hole Mc formed through the shaft portion 3b formed in the center. A first locked portion Ma and a second locked portion Mb are formed on the base end side. The magnetic member M may be a permanent magnet in addition to the resin component magnetized as in the present embodiment.

  On the other hand, as shown in FIGS. 29 and 30, the holding member 8 is formed of a cylindrical component having substantially the same diameter as the magnetic member M, and has an insertion hole 8d for inserting the shaft portion 3b formed in the center. A first locking portion 8a is formed which can be fitted with the mounting portion 1d of the interlocking member 1 and locked to the interlocking member 1. In addition, the holding member 8 is capable of fitting and locking the second locked portion Mb of the magnetic member M and locking the first locking portion Ma of the magnetic member M. It has a locking projection 8c. The locking concave portion 8b and the locking convex portion 8c constitute a second locking portion that can be locked to the magnetic member M.

  Then, the second locked portion Mb of the magnetic member M is fitted into the locking concave portion 8b of the holding member 8 while the locking projection 8c of the holding member 8 is fitted into the first locked portion Ma of the magnetic member M. This allows the holding member 8 to hold the magnetic member M as shown in FIGS. As described above, by fitting the mounting portion 1d of the interlocking member 1 into the first locking portion 8a of the holding member 8 holding the magnetic member M, as shown in FIGS.

Further, the shaft portion 3b of the housing member 3 is inserted and assembled into the insertion hole 1b of the interlocking member 1, the insertion hole 8d of the holding member 8, and the insertion hole Mc of the magnetic member M. Thus, the interlocking member 1, the holding member 8, and the magnetic member M are integrally rotatable about the shaft 3b.

  Thus, when the interlocking member 1 rotates in the same direction as the throttle grip G rotates forward, the magnetic member M attached to the interlocking member 1 via the holding member 8 also rotates in the same direction. As a result, the magnetic field changes according to the rotation angle, so that an output voltage of the magnetic sensor 4 corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 1 (ie, the rotation of the throttle grip G) can be obtained based on the output voltage. Angle) can be detected. 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 rotation angle of the throttle grip G is transmitted according to the transmitted rotation angle of the throttle grip G. The engine (drive source) can be controlled.

  On the other hand, when the interlocking member 1 rotates in the same direction with the reverse rotation of the throttle grip G, the magnetic member M attached to the interlocking member 1 via the holding member 8 also rotates in the same direction. As a result, the magnetic field changes according to the rotation angle, so that the output voltage of the magnetic sensor 4 corresponding to the rotation angle can be obtained, and the reverse rotation of the throttle grip G can be detected. As described above, when the reverse rotation of the throttle grip G is detected, the predetermined function of the motorcycle can be activated or deactivated. In the present embodiment, the present invention is applied to a motorcycle equipped with a constant vehicle speed holding device (auto cruise device) for maintaining a constant traveling speed, and rotates the throttle grip G in the reverse direction (the direction of normal rotation for fully opening the throttle from the initial position). (Rotation operation in the direction opposite to the above), the control for maintaining the constant vehicle speed can be stopped (canceled).

  Further, in the flexible board 5 according to the present embodiment, at least the boundary between the first part 5a and the third part 5c and the boundary between the second part 5b and the third part 5c are bent, so that the shape of the base member 6 ( (A shape extending from the end surface 6aa to the extension surface 6ba via the connection surface 6ab). Further, as shown in FIG. 18, a plurality of wirings h (electric cords) capable of transmitting a detection signal of the magnetic sensor 4 to the outside are connected to the second portion 5b of the flexible substrate 5 by soldering or the like. Holding portions 6c and 6d that can guide and hold the wiring h are formed integrally with the extension surface 6ba of the base member 6.
