The handle switch device according to the present embodiment is a device that is fixed to a handlebar of a two-wheeled vehicle and can operate various electrical components included in the two-wheeled vehicle. As shown in FIGS. 1 to 3, switch knobs 1a, 1b, etc. It is mainly composed of a formed switch case 1 and a guide pipe 2 attached to the switch case 2 and capable of guiding the throttle wire W.

  The switch case 1 is disposed in the vicinity of the throttle grip G at the right end of the handlebar H. For example, the switch case 1 is formed of a molded product having an upper and lower halved shape, and these half-shaped components are tightened with bolts or the like. It is comprised so that it may fix to the said handle bar H. The throttle grip G is for opening and closing the throttle valve of the two-wheeled vehicle in accordance with the turning operation by the driver. As shown in FIG. 5, a tube guide 7a is formed inside the throttle grip G.

  An interlocking portion 7 is integrally formed on the base end side (left end side in the figure) of the tube guide 7a, and the interlocking portion 7 has a drum-like locking formed at the tip of the throttle wire W. A groove 7b that can be inserted and locked through the piece T (see FIG. 8) is formed. Note that the proximal end side of the tube guide 7 a reaches the inside of the switch case 1, and the interlocking portion 7 is rotatably arranged in the switch case 1.

  The throttle wire W is composed of a metal wire having one end fixed to the interlocking portion 7 via a locking piece T and the other end connected to a throttle valve opening / closing operation portion (not shown) of the motorcycle. The opening operation side and the closing operation side are formed as a pair. However, when the driver rotates while holding the throttle grip G, the interlocking portion 7 also rotates, pulls one throttle wire W, opens the throttle valve, and can obtain any output of the engine, When the throttle grip G is returned, the other throttle wire W is pulled so that the throttle valve can be closed.

  Further, a lid 1c is fixed to the lower portion of the switch case 1 with a bolt BT (see FIG. 8), and a pair of guide pipes 2 are attached to the mounting position of the switch case 1 covered with the lid 1c. ing. As shown in FIGS. 3 and 4, a bent surface 1d that is bent upward from a substantially horizontal direction is formed at the mounting position of the guide pipe 2, and the interlocking portion 7 is provided in a substantially extending direction of the bent surface 1d. It is arranged.

  Furthermore, a positioning projection 3, a pair of left and right projections 4, 5, and a boss 6 are integrally formed at the mounting position of the guide pipe 2. Among these, the positioning protrusion 3 is composed of a protrusion formed in a rectangular shape in plan view, and convex portions 4 and 5 are formed on the left and right sides thereof (up and down in FIG. 4), respectively. The opposing surfaces of these convex portions 4 and 5 form substantially planar positioning wall surfaces 4a and 5a, respectively. The boss portion 6 has a bolt hole 6a through which a bolt BT for fixing the lid portion 1c to the switch case 1 can be inserted. The positioning projection 3 and the pair of convex portions 4, 5 Similarly, it protrudes downward from the switch case 1.

  On the other hand, the guide pipe 2 is made of a resin molded product that extends to the outside of the switch case 1 while being bent in an arc shape, and guides the tip end side of the throttle wire W that is interlocked with the throttle grip G. More specifically, as shown in FIGS. 6 and 7, the guide pipe 2 includes a tip portion A bent in an arc shape and an extending portion B extending in a substantially horizontal direction from the tip portion A. A throttle wire W is inserted from the tip end portion A to the extended portion B. The throttle wire W is formed of an integrally molded member. Note that a locking portion K for locking the guide pipe 2 and the switch case 1 is formed in the extending portion B of the one guide pipe 2.

An upper surface (an inner surface formed in an arc shape) of the tip end portion A forms a mounting surface 2a of the guide pipe 2 with respect to the switch case 1, and is a surface following the bent surface 1d at the mounting position of the guide pipe 2 (FIG. 7). See). Of the outer edges of the guide pipe 2 having a radial cross-sectional shape , the guide pipe 2 has a straight portion on the mounting surface 2a side with respect to the switch case 1 . Accordingly, the guide pipe 2 is in a state of being in surface contact with the bent surface 1 d of the switch case 1 in a state where the guide pipe 2 is assembled to the switch case 1.

  An insertion hole 2 b is formed at the tip end A of the guide pipe 2. The insertion hole 2b is formed by matching a U-shaped notch formed at the tip A of the pair of guide pipes 2, and is a positioning formed at the mounting position of the guide pipe 2 in the switch case 1. It is comprised so that the process protrusion 3 can be inserted. That is, in the state where the guide pipe 2 is attached to the switch case 1, the positioning projection 3 is inserted into the insertion hole 2b and positioning is performed.

  Further, as shown in FIG. 7, a portion 2 c formed by matching the pair of guide pipes 2 has an arc shape that follows the outer peripheral surface of the boss portion 6 formed at the mounting position of the guide pipe 2 in the switch case 1. In the state where the guide pipe 2 is attached to the switch case 1, the portion 2 c comes into contact with the boss portion 6 and is positioned in the extending direction of the guide pipe 2.

  Furthermore, the side surface 2d of the tip end portion A of the guide pipe 2 is flat, and when the guide pipe 2 is attached to the switch case 1, each of the positioning wall surfaces 4a and 5a of the convex portions 4 and 5 is provided. The side surface 2d abuts, and the guide pipe 2 is configured to be positioned in the left-right direction (direction substantially orthogonal to the extending direction). That is, in the assembled state of the guide pipe 2, the plane formed by the positioning wall surfaces 4a and 5a and the plane formed by the side surface 2d are brought into contact with each other by substantially surface contact.

  That is, the tip A of the guide pipe 2 has a flat mounting surface 2a and side surface 2d and a rectangular cross section (rectangular shape). The mounting surface 2a is a bent surface 1d and the side surface 2d is positioned. It is in a state of being in contact with the wall surfaces 4a and 5a for substantial surface contact, and is positioned. In particular, when the mounting surface 2a and the bent surface 1d are in contact with each other by surface contact, when the guide pipe 2 is held at the mounting position of the switch case 1 with a finger or the like, the guide pipe 2 rolls. And it can suppress that a position shifts.

Next, an operation of attaching the guide pipe 2 to the switch case 1 in the handle switch device will be described.
The switch case 1 is fixed at a position adjacent to the throttle grip G in the handle bar H, and the interlocking portion 7 is disposed in the switch case 1. Then, after removing the lid portion 1c of the switch case 1, the mounting surface 2a of the guide pipe 2 is matched with the bent surface 1d, and the guide pipe 2 is temporarily pressed with a finger or the like. At this time, the guide pipe 2 is in a state where the flat mounting surface 2a is in contact with the bent surface 1d, so that the guide pipe 2 is prevented from rolling and being displaced, and with a slight force. The guide pipe 2 can be reliably held down.

  Further, when the guide pipe 2 is matched with the bent surface 1d, the positioning projection 3 is inserted into the insertion hole 2b, and the side surface 2d is in contact with the boss portion 6 while the side surface 2d is the positioning wall surface of the convex portions 4 and 5. 4a and 5a are brought into contact with each other. As a result, when the guide pipe 2 is attached, the guide pipe 2 is positioned with respect to the switch case 1, and the displacement can be prevented more reliably.

  That is, the contact between the portion 2c and the boss portion 6 enables positioning in the extending direction of the guide pipe 2, and the contact between the side surface 2d and the positioning wall surfaces 4a and 5a causes the guide pipe 2 in the left-right direction. Positioning is achieved. In addition, by positioning the positioning projection 3 into the insertion hole 2b, it is possible to position both the extending direction of the guide pipe 2 and the left-right direction.

  In this state, after the locking piece T at the tip of the throttle wire W is locked in the groove 7d of the interlocking portion 7, the bolt BT is inserted into the bolt hole 6a and the lid portion 1c is attached to the switch case 1. Thereby, the guide pipe 2 is fixed at a predetermined position of the switch case 1, and the mounting operation is completed. In addition, after attaching the cover part 1c to the switch case 1, you may make it lock the locking piece T in the groove | channel 7d of the interlocking | linkage part 7. FIG.

As described above, according to the present embodiment, the mounting surface 2a of the guide pipe 2 with respect to the switch case 1 is a surface that is assembled in surface contact with the switch case 1, so that the guide pipe 2 is attached to the switch case 1. At the time of mounting work (temporary fixing to the switch case 1, etc.), it is possible to suppress misalignment and improve workability. In addition, since a flat surface that can come into contact with the positioning wall surfaces 4a and 5a is formed on the side surface of the guide pipe 2, it is possible to reliably perform the contact, and when the guide pipe 2 is attached to the switch case 1. In such a case, the horizontal displacement of the guide pipe 2 can be prevented.

  Furthermore, according to the above-described embodiment, it is possible to improve the workability at the time of attaching the guide pipe 2, and it is possible to reliably maintain the positioning of the guide pipe 2 even after the lid portion 1c is attached. When the motorcycle is used, the operability of the throttle wire W can be maintained well over a long period of time.

Having described the present embodiment, present invention is not limited thereto, for example, the mounting surface 2a of the distal end portion A of the guide pipe 2 so long as it is capable of surface contact with the bending curved 1d, the side surface 2d, etc. The other surface may not be a flat surface. Further, instead of the pair of guide pipes 2, these may be integrally formed so that the guide pipe is a single component.

The guide pipe has a linear portion on at least a part of the outer surface of the radial cross-sectional shape on the mounting surface side with respect to the switch case, and is a surface to be assembled in a state where the mounting surface is in surface contact with the switch case. As long as the handle switch device is capable of suppressing rolling when the guide pipe is attached to the switch case, it can also be applied to devices having different external shapes or those having other functions added. .
