Embodiment 1

[0035] First, Embodiment 1 of the present invention will be described based on the drawings.

[0036] Such as figure 1As shown, the two-wheeled motor vehicle 10 is provided with a vehicle frame 15, and the vehicle frame 15 is composed of the following components: a steering standpipe 11, a down tube (down tube) 12 extending obliquely downward from the steering stand tube 11, a down tube extending from the down tube 12, a lower tube (lower tube) 13 extending horizontally rearward from the lower end of the lower tube 13, and a seat rail 14 extending obliquely upward from the rear end of the lower tube 13 and supporting a seat 34 indicated by a two-dot chain line, And the two-wheeled motor vehicle 10 also has: a front fork 16, the front fork 16 is rotatably installed on the steering standpipe 11; a front wheel 17, the front wheel 17 is rotatably arranged at the lower end of the front fork 16; handle 18, the handle 18 is provided at the upper end of the front fork 16; a unit swin...

Embodiment 2

[0084] Next, Embodiment 2 of the present invention will be described based on the drawings.

[0085] exist Figure 7 in, for with Figure 6 The same symbols are used for common structures and descriptions are omitted.

[0086] The container 132B of the muffler 50B is composed of the outer container half body 52 and the inner container half body 59B. The inner container half body 59B is provided with an inner side wall portion 76B and an inner bottom portion 75B to close the opening 131 of the outer container half body 52. left-right direction), the inner bottom portion 75B is connected to the outer edge of the inner side wall portion 76B.

[0087] Also, the inner bottom portion 75B is bent so as to protrude toward the outer bottom portion 66 . Since the inner bottom portion 75B is bent so as to protrude toward the outer bottom portion 66 , rigidity can be improved compared to the case where the inner bottom portion 75B is formed straight. Since the rigidity of the inner b...

Embodiment 3

[0091] Next, Embodiment 3 of the present invention will be described based on the drawings.

[0092] exist Figure 8 in, for with figure 2 The same symbols are used for common structures and descriptions are omitted.

[0093]The muffler 170 is disposed on the right side of the rear wheel 23 and is supported by the engine 35 via a muffler support stay 171 . In addition, the muffler 170 is composed of the following components: a front side cover 172 connected to the exhaust pipe 46; a cylindrical main body 173 integrally formed with the front side cover 172 and extending in the left-right direction in the drawing; The rear end of the main body portion 173 is integrally formed and includes a rear side cover 175 of a tail pipe 174 .

[0094] Also, the muffler 170 is configured to be used in a two-wheeled motor vehicle ( figure 1 The symbol 10) overlaps with the rim 116 of the rear wheel 23 in side view. Next, the positional relationship between the muffler 170 and the wheel ...

Abstract

The present invention provides a configuration of a muffler for a combined swinging part which can be compactly configured in the width direction of vehicle. A back wheel (23) is provided with a dent part (176) which dents inwards in the vehicle width direction relatively to rim width (W1). The muffler (170) is provided with a projection (177) which projects from a body part (173) to the back wheel correspondingly with the shape of the dent part. The projection (177) can get close to the back wheel while a clearance (L2) between the muffler (170) and the rim is kept. Besides, if the volume ofthe muffler (170) is same with that of the muffler (200), the muffler (170) can reduce the dimension of the extension to outside in the vehicle width direction for a width (W2) correspondingly with the volume of the projection (177) compared with the muffler (200). Therefore, the muffler for the combined swinging part which can be compactly configured in the vehicle width direction can be provided.

Description

technical field [0001] The present invention relates to an arrangement structure of a muffler for a combined swinging part in which a muffler is arranged on the side of a wheel attached to the rear part of the combined swinging part. Background technique [0002] In the past, various two-wheeled motor vehicles with a combined swing portion structure have been proposed (for example, refer to Patent Document 1 ( figure 1 , figure 2 )). [0003] As in Patent Document 1 figure 1 As shown, in the motorcycle 1 (symbols described in Patent Document 1; the same below), the combined swing type power unit 5 is arranged in the middle part of the frame so as to be able to swing up and down using the front part as a fulcrum. Furthermore, an engine 6 is provided at the front of the power unit 5 , and an exhaust pipe 21 is bent and extended rearward from the engine 6 . Furthermore, a muffler 22 is connected to the rear of the exhaust pipe 21 , and the muffler 22 is arranged on the sid...
