Description

[Detailed description of the invention] [Industrial application field] This invention relates to motorcycles, and particularly to a pillion suitable for so-called up-muffler type motorcycles, which is disposed on the side of the upper part of the rear wheel. Regarding the step mounting structure.

[Prior Art] Some two-wheeled motorcycles are equipped with a pillion step on a step holder supported by the vehicle body. Additionally, a muffler may be installed on the side above the rear wheel. In this case, a dedicated muffler guard may be provided to cover the sides of the muffler. One such example is the one described in Japanese Utility Model Publication No. 52-25539.

[Problems with the Prior Art] However, if a muffler guard is provided in addition to the step holder, the number of parts installed on the side of the vehicle body on the side of the rear wheels increases, and the weight and the number of installation steps also increase. Moreover, the appearance tends to become complicated and design processing becomes difficult.

Therefore, the present invention solves these problems, reduces the number of parts and installation man-hours, reduces weight, and improves the appearance.

[Means for Solving the Problems] The motorcycle of the present invention is a motorcycle equipped with a muffler on the upper side of the rear wheel, the outer part of the muffler being supported by a body frame and extending downward. The feature is that a pillion step is attached to the muffler guard that covers the muffler.

[Operation of the invention] The up-muffler type muffler according to the invention is provided with a muffler guard on the outside, one end of which is supported by the vehicle body frame, and a pillion step is arranged laterally at the bottom of the muffler guard. It is set up. Therefore, this muffler guard is
It is an integrated step holder, and in addition to the original function of a conventional muffler guard, it is a multifunctional part that also functions as a step holder.

[Embodiment] FIGS. 1 to 4 show an embodiment of the present invention. Figure 1 shows the rear appearance of the vehicle body as seen diagonally from the rear, and Figure 2 shows the mounting structure of the muffler guard. Further, FIG. 3 is a schematic view of the vehicle body as viewed from the rear, and FIG. 4 is a side view of the master cylinder portion.

Figures 1 and 2 are attached to the rear of the motorcycle.
As shown in the figure, a muffler 2 is attached below a pillion seat 1. Muffler 2 is rear wheel 3
This is an up-muffler type installed on the upper side of the seat, and is located above the pillion step 4 on which the foot of the pillion seat 1 is placed. Further, a muffler guard 5 is provided on the outside of the muffler 2. This muffler guard 5 is provided so as to wrap around the outer circumference of the muffler 2.
It consists of a main body part 6 disposed along the outside in the longitudinal direction of the muffler, and a step holder part 7 that intersects with the muffler 2. The main body part 6 is bolted to the seat rail 8 at its end by bolts 6a, and the step holder part 7 is bolted to the down frame 10 connecting the seat rail 8 and the main frame 9 by bolts 7a and 7b. It is stopped. Further, a lower portion of the step holder portion 7 extends below the muffler 2, and a pillion step 4 is provided thereto to protrude toward the side of the vehicle body. Therefore, the step holder portion 7 functions as a step holder for attaching the pillion step 4, and at the same time functions as a muffler guard for the muffler 2. Therefore, by simply attaching the muffler guard 5, which is a single component, to the seat rail 8 and down frame 10 with three bolts 6a, 7a and 7b, the muffler guard and step holder can be formed at the same time. Therefore, compared to the case where the muffler guard and step holder are configured separately and attached, the number of parts is reduced, which is advantageous in terms of parts management and weight, and moreover, it is easy to install. Moreover, since the muffler guard 5 forms a single member in which the main body part 6 and the step holder part 7 are integrated, the rigidity can be increased. In addition, muffler 2 is down frame 1
0 via an L-shaped bracket 11 (see FIG. 2), one of which is fastened together with the muffler guard 5. By directly attaching the muffler 2 to the down frame 10, which is a part of the vehicle body frame, the support of the muffler 2 is ensured, and even if the pillion step 4 is used, the load of the occupant is supported by the down frame 10. Does not affect muffler 2. Moreover, since these attachment parts are located inside the side cover C, the appearance is good.

Note that FIG. 3 shows the arrangement of the muffler 2, etc. In other words, the muffler 2 is placed on the right side of the figure, sandwiching the rear wheel 3 supported on one side of the cantilevered swing arm A, and the sprocket S and damper D are placed on the left side.
are arranged. When the cantilevered swing arm A is used in this way, the muffler 2 can be moved closer to the center of the vehicle body, and the pillion step 4 can also be placed closer to the center of the vehicle body, thereby reducing the amount of protrusion toward the side of the vehicle body.

In addition, as shown in FIG. 1, the collective exhaust pipe 12 connected to the muffler 2 has a
It is housed inside the hem (not shown) of the fairing 14. The collective exhaust pipe 12 is provided within the fairing 14 with a joint portion 16 that connects with exhaust pipes 15 coming from each cylinder side of the V-type engine. The muffler 2 and the collective exhaust pipe 12 are made of a stainless steel alloy, and their surfaces are colored with a temper color through heat treatment. Therefore, when the joint portion 16 is disposed inside the fairing 14 in this manner, color matching of the exhaust gas pipes 12 becomes easy. In other words, conventionally joint part 1
6 is provided at a location visible from the outside on the outside of the felling 14, it is also necessary to apply color to the range visible from the outside on the joint portion 16 and exhaust pipe 15 side. However, when tempering, heat treatment is required for each part, and the color development is extremely subtle. This made color matching extremely difficult. However, in this embodiment, the joint portion 16
Since there is no need for color matching with the exhaust pipe 15 side,
You will be freed from such difficult work.

Further, as shown in FIGS. 1 and 3, a master cylinder 18 for a hydraulic brake operated by a rear brake pedal 17 is provided near the front step 13. That is, the front step 13 is a member that projects toward the side of the vehicle body from a step holder 19 attached to the lower part of the main frame 9, and a brake pedal 17 is provided near this member. This brake pedal 17 is connected by a link 20 to a master cylinder 18 disposed behind the front step 13. A cylinder guard 21 is provided on the external surface side of the master cylinder 18, and a hydraulic hose 22 is connected thereto. As shown in FIG. 3, the cylinder guard 21 is attached to the step holder 19 so that one side thereof covers the outer surface of the master cylinder 18. Master cylinder 18 is located at front step 1
Because it is located directly behind the feet of the occupant riding on the vehicle, it is in a position where the wind from the vehicle is likely to be drawn toward the center of the vehicle (as indicated by the dotted line arrow). However, when the cylinder guard 21 is provided in this way, the wind coming from the front of the vehicle body is not drawn in from behind the occupant's feet into the interior of the vehicle body on the master cylinder 18 side, but is guided rearward as shown by the solid line arrow. The guard 21 performs a rectifying action. Therefore, it contributes to noise prevention.

[Effects of the invention] A pillion step is attached to the muffler guard according to the invention. Therefore, the muffler guard becomes a multifunctional component that can also function as a step holder for the pillion step. Therefore, the number of parts and the number of installation steps can be reduced. Moreover, weight reduction can be achieved and appearance can be improved.
