On the inner side in the vehicle width direction, a throttle housing 82 which is a case covering the base end portion of the throttle 81 is provided.
In the throttle housing 82, one end of a throttle cable CT (see FIG. 1) is connected to the throttle 81, and the rotation operation of the throttle 81 is transmitted to the throttle valve in the carburetor 63 via the throttle cable CT. As a result, the driver can manually change the throttle opening, change the intake amount of the engine 12A (amount of fuel-air mixture), and adjust the engine output.
Further, the throttle housing 82 is provided with a switch (idle control switch described later) 83 that is operated by the driver with the thumb of the right hand. The throttle housing 82 is provided above the power unit 12 by a predetermined operation of the idle control switch 83. The starter motor 85 thus driven can be rotationally driven to start the engine 12A.

A clutch lever 86 that is operated by the driver with the left hand is provided at the left end portion of the handle bar 21, and the operation of the clutch lever 86 is transmitted to the clutch 12C via the clutch cable CC (see FIG. 1).

To the front wheel brake. Specifically, when the occupant pulls the brake lever 92 forward, the front wheel brake is activated.
The operation of the brake pedal 93 is transmitted to the rear wheel brake via the brake cable, and when the brake pedal 93 is depressed, the rear wheel brake is activated. When the brake lever 92 and the brake pedal 93 are operated, the brake light in the tail light 56 is turned on.
As described above, the motorcycle 1 is configured manually by adjusting the throttle opening, switching the clutch 12C, switching the gear position (including neutral), and operating the brake. In this configuration, a driving device such as an actuator is not used. For this reason, the vehicle body structure is simple and inexpensive (advantageous for cost reduction).

As shown in FIG. 2, a kick pedal 95 that is operated by the driver with the right foot is provided to be retractable and rotatable on the right side of the power unit 12 and behind the brake pedal 93. When the kick pedal 95 is rotated in the direction indicated by the arrow in FIG. 2, the driver can step on the kick pedal 95. When the engine is started, when the kick pedal 95 is pressed, the engine 12A is started. In other words, the motorcycle 1 can start the engine with either the starter motor 85 or the kick pedal 95. However, the configuration is not limited to this, and the engine may be started only by the starter motor 85.
In FIG. 2, reference numeral 96 denotes a pair of left and right side mirrors attached to the inside of the left and right grips (throttle 81, handle grip 87), more specifically, in the vicinity of the inside of the throttle housing 82 and the switch housing 89. .

FIG. 3 is a view showing the throttle 81 together with the peripheral configuration, and FIG. 4 is a view showing the internal structure thereof. In FIG. 3, the symbol RH indicates the right hand of the driver, and in FIG. 4, the symbol LT indicates the rotation axis of the throttle 81 (= the axis of the handle bar 21).
As shown in FIGS. 3 and 4, the throttle 81 includes a throttle pipe 81A (see FIG. 4) that is rotatably attached to the handle bar 21, and a grip portion 81B that is integrally attached to the outer periphery of the throttle pipe 81A. I have. The throttle pipe 81A extends from the grip portion 81B to the left and right center side of the handle (center side in the vehicle width direction), enters the throttle housing 82, and has a large diameter drum 81C formed integrally with the base end portion of the throttle pipe 81A. Is stored in the throttle housing 82. When one end of the throttle cable CT is attached to the drum 81C, the throttle cable CT is wound around the drum 81C according to the rotation of the throttle 81, or pulled out of the drum 81C, so that the throttle cable CT A throttle valve attached to the other end is opened and closed. In addition, the throttle housing 82 is formed in a split tightening structure that sandwiches the handle bar 21 from front to back or from above and below.
Here, the direction indicated by the arrow in FIG. 3 indicates the direction of rotation to close the throttle, and the opposite direction is the direction of rotation to open the throttle. This direction is the same as the conventional throttle opening / closing direction.

As shown in FIGS. 3 and 4, the throttle housing 82 is provided with an idle control switch 83 for setting prohibition / permission of idling of the engine 12A. Since the throttle housing 82 is close to the throttle 81, the driver can easily hold the throttle 81 with the right hand and the thumb of the right hand can easily reach the idle control switch 83. The switch 83 can be easily operated.
More specifically, as shown in FIG. 4, the idle control switch 83 is disposed using a dead space between the drum 81C of the throttle pipe 81A and the grip portion 81B, and further, than the drum 81C. Since it is arranged near the grip part 81B, it is not necessary to provide a separate space for securing a switch space, and the switch 83 can be arranged in a compact and easy-to-operate position.

  The idle control switch 83 is formed of a seesaw switch that pushes one end of the switch 83 in the longitudinal direction (pressing portions 83A and 83B (see FIG. 3)) with a finger of a hand. The two pressing portions 83A and 83B are arranged in order along the rotation direction of the throttle 81, and the pressing portion 83A on the throttle closing side functions as an idle stop switch that prohibits idling of the engine 12A. Portion 83B functions as a start switch that permits idling of engine 12A. Hereinafter, in order to make the explanation easy to understand, they are expressed as an idle stop switch 83A and a start switch 83B.

In this motorcycle 1, when a key is inserted into the key cylinder 22 (see FIG. 1) and the main switch (main SW) is turned on, if the idle control switch 83 is operated, the motorcycle 1 A control unit (also referred to as an electronic control unit (ECU)) that centrally controls each unit performs corresponding control. That is, when the idle stop switch 83A is operated, the idle stop control is performed and the engine 12A is stopped. When the start switch 83B is operated, the idle permission control is performed and the engine 12A is started. In this case, in the motorcycle 1, control for stopping ignition of the engine 12A is performed as idle stop control.
Since the motorcycle 1 has a configuration including a manual transmission and a manual clutch, the engine 12A is not started even when the start switch 83B is operated when the engine start condition is not satisfied. Specifically, the engine 12A is not started when the transmission 12B is in-gear (a state in which any gear position is selected) and the clutch 12C is connected. As this type of engine start condition, known engine start conditions can be widely applied.

By the way, the motorcycle 1 is provided with a cover member 151 that interlocks with the rotation of the throttle 81 and covers the idle control switch 83 when the throttle is open and exposes the idle control switch 83 when the throttle is closed. ing. Hereinafter, the cover member 151 will be described.
5A is a diagram showing the throttle 81 when the throttle is closed together with the peripheral configuration, and FIG. 5B is a diagram showing the throttle 81 when the throttle is opened along with the peripheral configuration. 6A is a side sectional view showing the cover member 151 when the throttle is closed together with the peripheral configuration, and FIG. 6B is a side sectional view showing the cover member 151 when the throttle is opened and the peripheral configuration. is there.
The cover member 151 is integrally formed with the grip portion 81B of the throttle 81, and the throttle 81 is covered so as to cover the surface of the throttle housing 82 from a flange portion 81D (see FIG. 4) whose diameter is enlarged at the proximal end portion of the grip portion 81B. Is formed on a curved plate-like cover extending along the circumferential direction centering on the rotation axis LT.

As shown in FIGS. 5 (A) and 6 (A), the idle control switch 83 is disposed below the rotation shaft LT of the throttle 81, and the cover member 151 is a rotation shaft when the throttle is closed. Since it is arranged on the upper rear side of the LT, the idle control switch 83 is exposed rearward and can be operated with the finger of the hand holding the throttle 81 (see FIG. 3).
In this case, as shown in FIG. 6 (A), the cover member 151 is located above the idle control switch 83, and thus covers the idle control switch 83 from above, and covers the idle control switch 83 and its peripheral parts. It can make it hard to get rainwater. More specifically, the cover member 151 is positioned at a position along the horizontal line L1 with the rear end 151R passing through the rotation axis LT, and the front end 151F is positioned forward of the vertical line L2 through the rotation axis LT. It functions as an upward convex covering member that covers the idle control switch 83 in a side view. For this reason, it is possible to efficiently avoid rainwater falling from above on the idle control switch 83 and its surroundings when parking or waiting for a signal.

As shown in FIGS. 5B and 6B, when the throttle is opened, the cover member 151 rotates downward and behind the rotation axis LT of the throttle 81 to cover the rear side of the idle control switch 83. Therefore, the idle control switch 83 becomes inoperable.
Here, the cover member 151 is formed in a shape that covers the idle control switch 83 when the throttle 81 is opened by a certain amount except for the throttle being closed (a state in which the throttle 81 is completely closed). The operation of the idle control switch 83 is prohibited within the range.

In this way, in this embodiment, the idle control switch 83 for prohibiting / permitting idle can be operated with the finger of the hand holding the throttle 81 when the throttle is closed, and cannot be operated when the throttle is open. It is formed. Thus, with a simple configuration, the operation of the idle control switch 83 can be prohibited when the throttle 81 is opened and the vehicle is traveling, and the idle control switch 83 can be easily operated when the throttle is closed. .
If the idle control switch 83 can be operated only when the throttle is closed, it is possible to stop the idle at an arbitrary timing when the driver does not intend to start, such as waiting for a signal, and then start the start. You can start idle when you do.

  In addition, since the motorcycle 1 has a configuration in which fuel is supplied by the carburetor 63, there may be a delay in the sudden stop of fuel supply as compared to the case where an injector (fuel injection device) is used. When the engine is stopped (idle stop), a complicated countermeasure structure such as fuel cut is required. However, by applying the present invention, the idle control switch 83 can be operated only when the throttle is closed. it can.

Further, the idle control switch 83 is provided on the throttle housing 82 attached to the handlebar 21 on the base end side of the throttle 81, and the cover member 151 is provided integrally with the throttle 81, so that an existing member is used. Thus, the switch 83 and the cover member 151 can be provided, and space can be used efficiently and an increase in the number of parts can be suppressed. Further, since the cover member 151 extends along the circumferential direction so as to cover the surface of the throttle housing 82 including the idle control switch 83 in the throttle opening range, the cover member 151 can be formed easily and compactly. Therefore, it is possible to provide an idle stop mechanism at low cost without using complicated electronic control, suppressing an increase in cost due to an increase in the number of parts.
Further, the idle control switch 83 is formed by a seesaw switch, and the two pressing portions 83A and 83B of the seesaw switch are sequentially arranged along the rotation direction of the throttle 81, and the pressing portion 83A on the throttle closing side is The idle stop switch for prohibiting idling of the engine 12A is used, and the pressing unit 83B on the throttle opening side is used as a starting switch for permitting idling of the engine 12A. The start switch can be operated up to a state in which a certain amount of opening that cannot be operated), and the startability can be improved.

  Further, in this configuration, the idle control switch 83 is provided below the rotation axis LT of the throttle 81, and the cover member 151 is positioned above the rotation axis LT of the throttle 81 when the throttle is closed. Thus, the cover member 151 can prevent rain water from being applied to the idle control switch 83 when the vehicle is parked or when the vehicle is stopped, such as waiting for a signal.

More specifically, it is provided at a position corresponding to the front upper side or the upper side of the rotation axis LT of the throttle 81, which is an area that is easy for the driver to visually recognize. Similarly to the idle control switch 83, the engine kill switch 84 is provided at a position away from the drum 81C (see FIG. 4) in the throttle housing 82 in the direction of the rotation axis LT of the throttle 81.

  With this configuration, the engine kill switch 84 is arranged using the space covered by the cover member 151 when the throttle is closed (see FIG. 7A), and the engine kill switch 84 can be easily operated in an emergency even when the throttle is open. Then, the engine can be stopped (see FIG. 7B). As a result, the engine kill switch 84 and the idle control switch 83 can be arranged with a simple configuration, and the ease of operation can be ensured.

<Third Embodiment>
8A and 8B show a third embodiment. More specifically, FIG. 8A shows the throttle 81 when the throttle is closed together with the peripheral configuration, and FIG. 8B shows the throttle 81 when the throttle is opened along with the peripheral configuration.
In the third embodiment, even when the cover member 151 covers the idle control switch 83, the width of the cover member 151 is narrow so that a part of the idle control switch 83 is exposed in the rotation axis direction of the throttle 81. Is formed. The rest is the same as in the first embodiment.
If a part of the idle control switch 83 is exposed in the rotation axis direction of the throttle 81, a part of the idle stop switch 83A and the start switch 83B are exposed. Therefore, the switches 83A and 83B are operated in an emergency even when the throttle is opened. Can be used as a conventional engine kill switch.
In the present embodiment, the case where the idle stop switch 83A and the start switch 83B are partially exposed has been described. However, at least a part of the idle stop switch 83A may be exposed, and the shape of the cover member 151 is within that range. Can be appropriately changed.

<Fourth embodiment>
9A and 9B show a fourth embodiment. More specifically, FIG. 9A shows the throttle 81 when the throttle is closed together with the peripheral configuration, and FIG. 9B shows the throttle 81 when the throttle is opened along with the peripheral configuration.
In the fourth embodiment, the idle control switch 83 is disposed at a position where the index finger of the hand holding the throttle 81 can reach when the throttle is closed, and where the hand holding the throttle 81 cannot reach when the throttle is open. ing.
More specifically, the idle control switch 83 is provided in the vicinity of the front end of the base end portion 92A on the upper surface of the base end portion 92A of the brake lever 92, thereby being disposed at a position as far as possible from the throttle 81, It can be operated with the index finger of the right hand only when the throttle is closed. Further, the idle control switch 83 is disposed at a position avoiding the pivot 92B penetrating the base end portion 92A and the one end CB1 of the brake cable CB attached to the base end portion 92A.

  The idle control switch 83 is formed as a small push-type switch. For example, when the switch is pressed once, it functions as an idle stop switch that prohibits the engine 12A from being idle. It functions as a start switch that permits idling of 12A, and when pressed again, it functions as an idle stop switch.

  According to this configuration, it is possible to prohibit the operation of the idle control switch 83 when the throttle 81 is opened and the vehicle is traveling with a simple configuration, and the idle control switch can be easily operated when the throttle is closed. can do. In addition, since the idle control switch 83 is provided on the brake lever 92, a switch can be provided using existing members, space can be used efficiently, and an increase in the number of components can be suppressed. Further, it is not necessary to provide the cover member 151 on the throttle 81, and a conventional throttle can be used.

The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.
For example, in the above-described embodiment, the idle control switch 83 is an idle control switch that can both prohibit and permit idling of the engine 12A. However, the present invention is not limited to this, and the engine 12A is prohibited from idling. An idle control switch or an idle control switch that permits idling of the engine 12A may be used. Further, a starter switch for starting the engine 12A or other switches may be separately provided in the vicinity of the throttle 81, or a switch box having this type of switch may be disposed.
In the above embodiment, the case where the idle control switch 83 is provided on the throttle housing 82 or the brake lever 92 has been described. However, the present invention is not limited thereto, and the finger of the hand holding the throttle 81 reaches when the throttle is closed. The position of the idle control switch 83 may be changed within a range that does not reach when the throttle is open.

Moreover, although the said embodiment demonstrated the case where this invention was applied to the motorcycle 1 provided with the starter motor 85, it is not restricted to this. For example, the present invention can be applied to a case where an idle control switch for manually prohibiting idling of the engine 12A is provided for a motorcycle that does not include the starter motor 85 and starts the engine only by the kick pedal 95. is there.
