Problems solved by technology

[0004] However, in the muffler 10, since the muffler main body 11 is formed in a cylindrical shape having an axis in the direction along the exhaust pipe 17, it is easy to increase the outer diameter of the muffler main body 11 when securing a necessary capacity.
Thus, when the muffler 10 having a large outer diameter is mounted on a motorcycle, there is a problem that the muffler 10 protrudes in the vehicle width direction from the rear of the motorcycle, thereby increasing the vehicle width.

Embodiment 1

[0038] First, Embodiment 1 of the present invention will be described based on the drawings.

[0039] Such as figure 1 As shown, the two-wheeled motor vehicle 10 is equipped 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; 12, a lower tube (lower tube) 13 extending horizontally to the rear at the lower end of the lower tube; And the motorcycle 10 also has: a front fork 16, the front fork 16 is rotatably mounted 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 on the upper end of the front fork 16; a unit swing (described in detail later) 22, the unit swing 22 is provided on the connecting member in a vertically rotatable manner via a pivot 21 19, the connecting member 19 further extends rearward from the rea...

Embodiment 2

[0090] Next, Embodiment 2 of the present invention will be described based on the drawings.

[0091] exist Figure 7 in, for with figure 2 The same symbols are used for the same structure and descriptions are omitted. In addition, for the convenience of description, the muffler support brace 51 is shown with a dashed-two dotted line.

[0092] exist Figure 7 In the figure (a), the muffler 50B is equipped with the drum 145 integrally formed with the side wall part 143 which is an ellipse cylindrical shape in side view, and the ellipse-shaped first bottom part 144. Let W1 be the minimum width of the side wall portion 143 when viewing the drum 145 (viewing from a direction perpendicular to the first bottom portion 144 ).

[0093] Figure 7 Figure (b) is along the Figure 7 In the cross-sectional view of line b-b in (a), the interval between the first bottom 144 and the elliptical second bottom 147 combined by the first partition 145 and the second partition 146 is H1. In ...

Abstract

The present invention provides a flat silencer. In the silencer (50B), A clearance (H1) between a first bottom (144) and a second bottom (147) is configured to be less than a minimum width (W1) of a side wall portion (143) viewing from a direction orthogonal to the first bottom (144). The flat silencer (50B) is formed in the direction orthogonal to the first bottom (144). Thereby, the flat silencer (50B) is formed.

Description

technical field [0001] The present invention relates to a muffler provided in the middle of an exhaust pipe extending from an engine. Background technique [0002] In the past, as a device for reducing the exhaust sound from an engine, a muffler is known (for example, refer to Patent Document 1 ( figure 1 )). [0003] As in Patent Document 1 figure 1 As shown, in the inside of the muffler main body 11 of the muffler 10 (the number described in Patent Document 1. The same below), the first partition 12 is provided at a position close to the upstream, and the second partition 13 is provided at a position close to the downstream, so that Three chambers of the first expansion chamber 14 , the second expansion chamber 15 , and the third expansion chamber 16 are partitioned. [0004] However, in the muffler 10 , since the muffler body 11 is formed in a cylindrical shape having an axis along the exhaust pipe 17 , it is easy to increase the outer diameter of the muffler body 11 t...
