2. Description of the Related Art The muffler mounting angle in conventional motorcycles and the like is fixed.
In the case of a model that is also used as an off, the muffler is generally attached at an angle that flips up rearward and upward for reasons of off-road running performance or its image.
For this reason, when installing a trunk as a side case for touring, the muffler side trunk interferes with the muffler, so either install it on the outside of the muffler or configure the exhaust pipe joint with a flexible joint to install the muffler. The muffler was held in a substantially horizontal direction by changing the angle, and the trunk was attached above it.

When the trunk is attached to the outside of the muffler as described above, the entire width of the vehicle body is widened, which may increase wind resistance during traveling, and the exhaust pipe and the muffler may be installed. With a structure in which the flexible joint connects the muffler downwards and the trunk is arranged above it, not only is the flexible joint itself a small angle at which it can be mounted, but it also has a structure that ensures sealing performance. There is a problem that it has to be complicated, and further, when the muffler is on only one side of the vehicle, the trunk mounting width becomes asymmetrical and there is a problem in stability during running etc. Was seen. The present invention was devised to solve the above-mentioned drawbacks, and an object of the present invention is to provide a variable muffler whose mounting angle can be easily changed according to the usage situation of a motorcycle or the like. .

The muffler body 4 of the motorcycle 1 is connected to the exhaust pipe 2 by a joint 3 having a bent portion. The rear end of the exhaust pipe 2 and the joint 12 of the joint 3 are fixed by tightening with a tightening bolt 13. In the normal mounting state, the muffler body 4 is inclined rearward and upward as shown in FIG. The muffler body 4 is fixed to the bracket 6 attached to the vehicle body frame via the bracket 5. On the other hand, when the side case is attached, since the side case 7 is attached to the side surface of the vehicle body, the tightening bolt 13 that fastens the joint 12 of the joint 3 and the rear end of the exhaust pipe 2 is loosened to join the joint 3. By rotating around the axis of the portion 12 and tightening the tightening bolts 13 again, it is held in a substantially horizontal position below the side case 7. When the tail pipe 11 faces downward, the joint 3 is detached from the muffler body 4, rotated around the axis of the joint 12 of the joint 3, and then rejoined to the muffler body 4. In this case, a stay 8 is attached between the bracket 6 of the vehicle body frame and the bracket 5 of the muffler body 4 to be attached.

Here, how to change the attachment angle of the muffler body 4 is geometrically shown in FIGS. 2 (a), (b), (c) and FIG.
A description will be given based on (a), (b), (c), and (d). (i) When the axis of the joint between the exhaust pipe and the joint and the axis of the muffler body are on the same plane: In the joint of the exhaust pipe 2 and the joint 3 in Figs. 2 (a), (b) and (c). The muffler body 4 is normally attached (solid line) and the side case is attached with the axis of rotation of the joint 3 rotating at the joint with the exhaust pipe 2 being l 1 and the axis of the muffler body 4 being l 2. The exhaust pipe is designed so that it is on the same plane at the time (dotted line), and in that case, the bisector of the mounting angle when the muffler body 4 is normally mounted and when the side case is mounted is made to coincide with the axis l 1. The rear end of 2 and the joint portion 12 of the joint 3 are fastened and fixed by the tightening bolt 13. Under such a condition, the muffler body 4 is rotated 180 ° around the axis l 1 at the joint between the exhaust pipe 2 and the joint 3 to move the muffler body 4 downward to change the mounting angle. In this case,
When the tail pipe 11 faces downward, the lid 9 of the muffler body 4 integral with the joint 3 is attached to the muffler body 4.
The muffler body 4 from the joint 12 of the joint 3
After rotating around the axis l 1 , the muffler body 4 and the lid 9 integral with the joint 3 are fixed with bolts to integrally couple the muffler body 4 and the joint 3.

(Ii) When the axis at the joint between the exhaust pipe and the joint and the axis of the muffler body are not on the same plane, an arbitrary point on the axis l 1 at the joint between the exhaust pipe 2 and the joint 3 in FIG. in the last bending point vicinity of the axis l 1 on a and exhaust pipe 2 and a, the axes of l 1 and the muffler main body 4 at the junction between the exhaust pipe 2 and the joint 3 the intersection of the l 2 b , The axis of the muffler body 4 is l 2, and the point a when the point b is the origin is shown in FIG.
Two-dimensional coordinates on a plane perpendicular to the (axis l 2 ), where the vehicle body width direction is the X axis and the direction perpendicular thereto is the Y axis, and the coordinates (X 2 , X 2 ) are the coordinates, the muffler is normally attached. 3 (b) as viewed in the direction of arrow A (axial direction of the muffler body) in FIG. 3 (c), and when the side case is attached, the X and Y axes in FIG. When the vehicle body width direction is represented by the X-axis and the direction orthogonal thereto is represented by the Y-axis in the two-dimensional coordinates at, the state of FIG. 3D in the direction of arrow B in FIG. X 1 ,
-X 2 ). Here, if X 1 = X 2 is designed, the point a does not move even when rotated 90 °, and the muffler body 4
Are located above and below the same plane when viewed from the top. In this case, in order to move the position of the muffler body 4 from the position of the normal mounting state to the state of mounting the side case, the joint 12 of the rear end of the exhaust pipe 2 and the joint 3 is moved.
Loosen the tightening bolt 13 that is tightening, and rotate 90 ° around the axis of the joint 12 of the joint 3, move the muffler body 4 downward to change the mounting angle, and then tighten the bolt 1 again.
The muffler body 4 is fixed by tightening 3.
When the tail pipe 11 faces downward, the lid 9 of the muffler body 4 integral with the joint 3 is removed from the muffler body 4 and the muffler body 4 is rotated 90 ° around the axis l 1 of the joint 12 of the joint 3. After the rotation, the muffler body 4 and the lid 9 that is integral with the joint 3 are fixed with bolts to integrally couple the muffler body 4 and the joint 3. At that time, the muffler body 4 moves to the position when the side case is attached. In that state, when the hole of the lid 9 of the muffler body 4 is aligned with another mounting hole in the muffler body 4 and the bolt 10 is retightened to complete the attachment, the mouth of the tail pipe 11 comes to a position facing downward. It goes without saying that the same can be done in the opposite case.
