Problems solved by technology

[0005] However, since the descaling pipe 77 is extended to the vehicle body rear, and its front end is arranged above the rear wheel 13, foreign matter such as dust rolled up by the rear wheel 13 may invade from the front end of the descaling pipe 77.
For this reason, the technology in Patent Document 1 has a problem in that it is necessary to provide a cooling air cleaner 70 to prevent the intrusion of foreign matter, which leads to an increase in the cost of the vehicle.

Embodiment Construction

[0022] The best mode for carrying out the present invention will be described below based on the drawings. In the drawings, "front", "rear", "left", "right", "up", and "down" are directions seen from the driver's side. In addition, the attached drawing is a figure seen from the direction of a symbol.

[0023] Fig. 1 is a partial cross-sectional side view of a motorcycle equipped with a power transmission device of the present invention. A motorcycle 10 is mounted on the vehicle so that a power unit 15 can swing freely through a link mechanism 14 comprising a pivot 12 at the rear of a vehicle frame 11. Vehicles on rack 11.

[0024] The power plant 15 is composed of an engine 16 and a power transmission device 17 provided behind the engine 16 . The power transmission device 17 is composed of a unit case 18 and an unillustrated transmission. The power of the engine 16 is transmitted to the rear wheels 19 by swingably mounting the unit case 18 on the vehicle frame 11 .

Abstract

The invention provides a power transmitter for a motorcycle capable of suppressing a foreign body from invading and reducing the cost. The power transmitter (17) for a motorcycle, on a assemble housing (18) thereof, is provided with an opening (33) which connecting with a guiding pipe (34) for exterior air then supplied to the assemble housing (18) by the guiding pipe (34), so that the power transmitter (17) is cooled, where, a pedal supporting member (72) is equiped substantially over the opening (33), while an front end part (34a) of the guiding pipe (34) for exterior air is fixed on the pedal supporting member (72). In addition, an umbrella-shaped member (81) is arranged near the front end part (34a) of the guiding pipe (34).

Description

technical field [0001] The present invention relates to a power transmission device of a motorcycle that cools the power transmission device by supplying external air into an assembly housing of the power transmission device. Background technique [0002] The unit case of the power transmission device is mounted on the frame so that it can swing freely, and an opening is provided in the unit case, and external air is supplied into the unit case from the opening to cool the power transmission of a motorcycle such as the power transmission device. The device is well known (for example, refer to Patent Document 1). [0003] Patent document: Patent No. 3064389 (2nd figure) [0004] In Fig. 2 of Patent Document 1, a combined swing engine 11 is swingably mounted on the vehicle frame 10, and a descaling pipe 77 is connected to the transmission case 12 constituting a part of the combined swing engine 11 and extends obliquely upward. A cooling air cleaner 70 is connected to the fro...
