Abstract

PURPOSE:To secure the degree of strength in a carrier to the full by supporting the resin carrier being supported by each upper end of a symmetrical pair of metallic side stays, in holding it in between from both sides with each of upper ends of both these paired side stays. CONSTITUTION:This carrier 33 being attached to the rear of a body frame is composed of a symmetrical pair of aluminum die casting side stays 44 and a resin carrier 45 being held in between from both sides with each upper end of these paired side stays 44 and supported by these stays 44. The side stays 44 are screwed to both first and second brackets 46, 47 installed each in both rear ends of each of symmetrical back stays 40 and each of symmetrical seat rails 39 by a bolt 48, supporting the carrier 33. A races groove 49 extending in the longitudinal direction is formed on an inner surface of a pinch part 44b of each side stay 44, and after projection strip part 51 formed on the side of a carrier 45 is fitted in this recess groove, these pinch parts 44b, 44b themselves of the symmetrical side stays 44, 44 are clamped together by a clamper 54.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a rear carrier for a motorcycle, which is comprised of a pair of left and right Zydo suspensions and a loading platform supported by both side stays.

(Prior Art) Conventionally, there is a rear carrier for a motorcycle as disclosed in, for example, Japanese Unexamined Patent Publication No. 61-81872.

According to this, a pair of left and right side stays are attached to the rear part of the vehicle body frame, and each side portion of the loading platform is placed on each upper end surface of both side stays. Bolt holes are formed in each side of the cargo receiving platform, and the two cargo receiving platforms are screwed onto the upper end of each side stay by bolts inserted through these bolt holes.

(Problems to be Solved by the Invention) By the way, in the J-type configuration, if the carrier is to be made lighter, it is conceivable to make the loading platform made of resin, but if this is done, the following will occur. cause inconvenience.

That is, firstly, if the loading platform is made of resin and bolt holes are formed on each side thereof as described above, the strength of this portion will be reduced, and there is a risk that the loading platform will be easily damaged by the load. .

Second, since each side of the loading platform is exposed outward,
For example, when loading and unloading cargo from this loading dock,
It is easy for the cargo to collide with the sides of the cargo receiving area (therefore, there is a risk that the sides of the cargo receiving area may be easily damaged). It is easy to see the appearance from the inside and outside, but this is not the same as the gear rear.

(Object of the invention) This invention is based on
Firstly, when the f::jsn stand is made of Todo 1 resin, C= is also made to maintain the strength of 2:1- minutes, and the 24th ．． 2d: When loading and unloading the item i, make sure that the item does not collide with the side ε of the 6:j pedestal, and the damage of the item 5 is 1υ no 11".

A concave groove 4 (4) or bar (6) extending in the direction from the rear of the groove (1) to the groove (6) is formed on the opposing surface of each groove, and within this groove (4)
A pair of engagement holes 50 and 50 are formed at the rear. On the side surface of the loading platform 715 corresponding to the clamping portion 441 of each lead swivel 44, there is formed a concave groove 4L and a convex strip 5]'/J' into which the groove can be removably fitted. , this protrusion 1

Each lead is connected to 44 and ↑ cradle 45:
When assembling, it supports each grommet 53 slidably and functions as a guide during assembly. Also,
When the concave groove 49 and the convex strip 51 fit together, the gap created at the joint between the clamping part 44[) of each guide stay 44 and the side part of the cargo receiving platform 45 is closed. Carrier 3:3 d) It is protected that the carrier can see through the gap.

On the other hand, the rear fender 34 is connected to the base 44) of each rear fender 44 with a pair of poles l-6464 after [111].
Further, the rear fender 34 is supported by the gear rear 33.

Also, on Pax Day 40, the third bracket h 66

The count, 69, is in charge of the luggage straps.11. 3. (Effects of the Invention) According to this invention, the cargo receiving platform is held from both sides by the upper end of the noid slur from the left and right. Therefore, first, it is not necessary to form conventional bolt holes on each side of the loading platform. 11. Low strength of the front rest due to the formation of pores is prevented. be done. .

Moreover, since the clamping L-j of the 1-deployment pedestal can be performed by pressure contact over each side of the front cradle, it is possible to perform the clamping L-j of the 1-deployment pedestal by pressure contacting the front pedestal. Compared to locally tightening the frame, it is possible to prevent unevenness in the strength of the frame and pedestal.

This allows the loading platform to maintain sufficient strength.

Also, secondly, the loading platform is
- Since it is pinched from the stone, (;:f each side of the pedestal is covered with ri 1 ~ sde. Moreover, since this reid slides and the 4th generation is made), t: ri + -!
It will be ensured that it is protected by the 3 (ijllrM) of the M' pedestal.

Therefore, even if the cargo tries to collide with the side of the cargo receiving platform when loading and unloading the cargo onto the receiving platform, this will be prevented by the above-mentioned Zytos Day and damage to the receiving platform will be prevented.
j2 is done.

Thirdly, as mentioned above, there is no need for bolt holes in the cargo receiving platform, so the appearance of the carrier is made to look the same as the conventional bolt holes are not visible.
