Therefore, each of the operating lever bodies 43 and 44 is provided so as to share the same rotation center, that is, in this embodiment, to rotate around the center of the through hole 23, and They are arranged circumferentially apart from each other around the center of rotation. The operating levers 45, 52 are arranged so that when the grip 17 is gripped with the left hand, the operating levers 45, 52 can be operated with the thumb of the left hand. In particular, as shown in FIG. 3, the operating lever 52 is arranged so that it can rotate within an angular range such that it is tilted slightly toward the grip 17. This reduces the distance between the operating lever 52 and the thumb, allowing for operation in the depressing direction. It can be easily rotated in the low beam display direction (described later) by force, and can also be easily rotated in the high beam operation direction (described later) by diagonally upward pushing force, making operation of the control lever 52 with the thumb easier and more reliable. be.

Further, in the center of the through hole 23 of the switch main body 22, there is provided a push button 58 made of hard synthetic resin, which serves as the central axis of rotation of each of the operating levers 45, 52. The push button 58 is inserted through the center hole 48 of the operating lever body 43 and the recess 53a of the other operating lever body 44 from the back side.
It is engaged with hook portions 59 and 60 of each operating lever body 43 and 44 to prevent it from coming off. A contact 61 directly facing the contact 38 is housed within the push button 58, and a metal biasing body 62 such as a coil spring is interposed between this and the terminal plate 37. For example, a horn switch C is formed by these. Therefore, this switch C depresses the push button 58 to open the contact 61 which is electrically connected to the terminal board 37 via the biasing body 62.
The contact point 38 is brought into contact with the contact point 38 to close the contact point 38.

In addition, D and E in FIG. 3 indicate the above-mentioned switch operation surface 2.
Arrow display for selecting the left and right flasher lamps 15 provided on 2a, F and G are also on the switch operation surface 22
A is a display showing the beam direction of the headlamp 13 provided, and H is a schematic display of a horn provided on the upper surface of the push button 58. Another handle switch device 21 adjacent to the grip 18 is a push-button switch 64 for operating a starter (not shown) for starting the engine.
It also has a lever type switch 65 for turning on and off the power to the head lamp 13, tail lamp, etc.

Therefore, since the operating levers 45 and 52 of the plurality of switches A and B share the same rotation center as in the above configuration, and are arranged circumferentially apart from each other around this rotation center, Although the switch device 1 is provided with a plurality of switches A and B, the entire switch device 1 can be made compact, and thus the switch device is suitable for use with the handle 5. The operation levers of the plurality of switches A and B are arranged in a small area for easy viewing, and the rotation operations of the operation levers 45 and 52 are unified around a common push button 58. Therefore, if you are aware of this, even beginners can avoid accidentally pushing, pushing up, or pulling the operating levers 45, 52.
Misoperation such as sliding can be further prevented. Moreover, in the case of this embodiment, the operating lever 52
The relationship between the upward and downward displacement accompanied by the rotation of the operating lever 45 matches the beam switching direction, and the displacement in the left and right direction accompanied by the rotation of the operating lever 45 and the flash lamp 15
Since the positions of the control levers 45 and 52 match, it is easy to recognize the operating direction of the operating levers 45 and 52, and further erroneous operation can be prevented. In addition, in this embodiment, there is a push button 58 at the center of rotation of the operating lever.
Since the pushbutton 58 can be checked with a finger without looking at the handle switch, the user can easily move the finger from there to the desired operating lever, which is particularly convenient for beginners. .

On the other hand, in the above configuration, a circular through hole 23 is formed in the switch operation surface 22a of the switch device main body 22, and the neck portions 43a, 44a of the operation lever bodies 43, 44 are brought into contact with the opening inner circumference of the through hole 23. At the same time, since the push button 58 serving as the center axis of rotation is inserted from the back side into the sliding parts 46, 53 located on the switch operation surface 22a, the operation lever bodies 43, 44 can be moved without dividing the switch device main body 22. can be rotatably supported,
It is possible to eliminate the need for a special switch lid and its attachment means as in the past.

Therefore, the number of parts can be reduced to that extent and the structure can be simplified, making assembly work easier, and making it possible to reduce weight and cost.

Although this embodiment is configured as described above, the present invention is not limited to the above embodiment. For example, horn switch C may be omitted. In the above embodiment, the push button 58 of the horn switch C is used as the rotation center axis of the operation levers of the plurality of switches, but the rotation center axes of the operation levers are arranged concentrically so that they are mutually guided. It may also be configured to rotate. In addition, in the embodiments of the present invention, the specific structure, shape, position, material, etc. of the switch device main body, a plurality of switches, the operating lever, the rotation center, etc. are the same as those described above, unless it goes against the gist of the invention. It goes without saying that the present invention is not limited to the embodiments and can be implemented with various configurations.

According to the present invention described in detail above, the operating lever body can be rotatably mounted without dividing the main body of the switch device, and a special switch lid and its mounting means as in the prior art are not required. Therefore,
Accordingly, the number of parts can be reduced and the structure can be simplified, making assembly work easier and contributing to weight reduction and cost reduction.
