Description

[Detailed Description of the Invention] The present invention relates to a silencer support device for a motorcycle, which supports a silencer stay using a pillion step mounting bolt.

In a general motorcycle, a stay 2 for suspending a silencer 1 is located near a pillion step 3, as shown in FIG. Conventionally, however, the stay 2 and pillion step 3 are attached to the step holder 4 using different bolts and nuts.
Since the two parts were attached to each other, it took time and effort to attach them, and the structure of the parts to which they were attached became complicated, detracting from the aesthetics. Furthermore, since the stay 2 is directly fixed to the step holder 4, the vibrations of the muffler 1 are propagated to the vehicle body, which may cause discomfort to the driver.

An object of the present invention is to provide a silencer support device for a motorcycle that can eliminate such drawbacks. Therefore, in the present invention, a stay is inserted and fixed between the step bracket for installing the pillion step and the step holder, and the silencer is suspended from the stay via an elastic member to reduce vibrations to the vehicle body. The present invention provides a muffler support device for a motorcycle as described above.

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, the same elements as those shown in FIG. 1 are given the same reference numerals.

In FIG. 2, the pillion step 3 includes a step portion 3a and a bracket 3c connected to the portion 3a by a pin 3b, and a rotation prevention plate 5 shown in FIG. 3 is fixed to the side surface of the bracket 3c. be. This plate 5 is provided to prevent a collar washer 6 (to be described later) from rotating, and a bolt hole 5a in the center thereof is oval, and one half of the plate 5, for example, the right half 5c, is attached to the collar washer 6, which will be described later. A claw 6a protruding from the tip of the collar part of 6
(See FIG. 3), and the left half 5d is formed to have a smaller diameter than the right half.

The device according to the present invention performs the above pillion step 3.
A cylindrical elastic member 7 is interposed between the bracket 3c and the step holder 4, and the elastic member 7 and the bracket 3c are attached to the step holder 4 with a pillion step mounting bolt 8. There is.

In this embodiment, the elastic member 7 is made of rubber, and the collar washer 6 is fitted into the inner periphery of the elastic member 7, and a groove 7 is provided on the outer periphery of the elastic member 7.
A support ring 9 to which the stay 2 of the silencer 1 is attached is fitted into the support ring 9a.

The color washers 6, as shown in FIG.
It has a cylindrical body part 6a having a substantially oval cross section and a washer part 6b forming an end surface of this cylindrical body part 6a,
The hole 5a of the plate 5 is provided at the tip of the cylindrical body 6a.
A claw 6c that fits into the right half 5c of the washer part 6b is formed, and a guide 6d is formed upright on one half of the peripheral edge of the washer part 6b, for example, on the left half peripheral edge. This guide 6d is adapted to engage with the arcuate end 4a of the step holder 4, and is adapted to prevent rotation during installation. The cylindrical portion 6a of the collar washer 6 has the pawl 6c fitted into the right half 5c of the bolt hole 5a of the plate 5, and both end portions of the pawl 6c are connected to the hole 5c of the bolt hole 5a. The plate 5 is fitted into the plate 5 in a manner that it is locked to the stepped portions 5b, 5b at the border with the plate 5, and the bolt 8 is inserted through the plate 5. In addition, the above color washers 6
The length l of the washer portion is set to be approximately equal to the width of the elastic member 7.

Now, when the bolt 8 is tightened with the nut 10, the step bracket 3c is fixed to the step holder 4 via the collar washer 6. The collar washer 6 is prevented from rotating by the cooperation of the claw 6c of the cylindrical body part 6a and the hole 5a of the step bracket 3c, and by the cooperation of the guide 6d of the washer part 6b and the arcuate end part 4a of the step holder 4. It is fixed to the step holder 4. On the other hand, the elastic member 7 is held between the plate 5 and the washer portion of the collar washer 6 without being deformed by pressure due to the action of the collar portion 6b of the collar washer 6. In this way, the collar washer 6 is fixed between the bracket 3c of the pillion step 3 and the step holder 4 using the pillion step mounting bolt 8, and the silencer 1 is suspended from the collar washer 6 via the elastic member 7. Support below.

As explained above, the support device for a silencer according to the present invention is configured so that the stay of the silencer is suspended and supported by the step holder using the mounting bolt of the pillion step as described above. The structure is simple, the assembly is easy, the appearance around the step holder can be improved, and vibrations of the silencer can be absorbed by the elastic member.
