(Example) An example of the present invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, a motorcycle 1
A cargo such as a trunk 4 is placed on a cargo platform 2 fixed to the rear of the vehicle via an intermediate cargo platform 3. This trunk 4 has a substantially rectangular parallelepiped shape, and bolt holes 4a to 4d are bored in the four corners of the bottom of the trunk 4, and each of the bolt holes 4a to 4d is bored in each of the stays 5 provided at the four corners of the inner loading platform 3. They are formed corresponding to the provided bolt holes 5a to 8a, respectively. Then, insert the bolts 6 to 9 into the bolt holes 4a to 4d, 5a to 5d, respectively, and
By screwing nuts 10 to 13, respectively, the trunk 4 and the middle cargo bed 3 are integrally fastened.

The middle loading platform 3 has a substantially rectangular frame 14, and a pair of substantially parallel vertical members 15, 16 are installed at a substantially central portion of the frame 14 at a predetermined distance. A hook portion 17 with an alligator-shaped front end is fixed to the front end of the hook 16, and a bracket 1 made of a plate is attached to the rear of both vertical members 15 and 16.
8 is fixed. The bracket 18 is formed into a step-like shape with a downwardly concave portion approximately in the center thereof.
A mounting screw hole 18a is provided in this bent step.

Here, the hook portion 17 engages with the front horizontal member 2a installed in the left-right width direction of the outer frame 2A of the loading platform 2, and the bracket 18 engages with the front horizontal member 2a when engaged.
A rear horizontal member 2 installed on the outer frame body 2A behind a.
Located behind b.

Further, a mounting member 19 made of a plate material is attached to the rear side member 2b and the bracket 18 from below, and this mounting member 19 has a front bent portion 19a and a horizontal portion 19b connected to the front bent portion 19a. , and a rear bent portion 19c continuous to this horizontal portion 19b. The front bent portion 19a is raised substantially perpendicularly to the horizontal portion 19b, while the rear bent portion 19c is raised upward relative to the horizontal portion 19b and is inclined rearward. On the other hand, a long hole 19d is bored in the horizontal portion 19b substantially in the center thereof. A threaded portion 20a of a fastening bolt 20 is inserted through the elongated hole 19d of the mounting member 19, and this threaded portion 20a is screwed into the mounting screw hole 18a of the bracket 18 by rotation of the knob portion 20b.

With this structure, the following steps are required to secure the trunk 4 to the cargo platform 2.

First, after integrally fastening the middle loading platform 3 to the bottom side of the trunk 4 as described above, the hook portion 17 on the bottom side of the middle loading platform 3 is engaged with the front horizontal member 2a of the loading platform 2 from behind, and the trunk 4 and the middle loading platform 3 are placed on the loading platform 2. Next, the mounting member 19 is held so that its inner surface side faces the bracket 18, and the front end of the rear cross member 2b of the loading platform 2 is brought into contact with the inner surface of the front bent portion 19a of the mounting member 19, so that the bracket 18
The rear lower end edge 18e of the rear bent portion 19c is brought into contact with the inclined inner surface of the rear bent portion 19c. In this way, the fastening bolt 20
The threaded portion 20a is loosely inserted into the elongated hole 19d of the mounting member 19, and the threaded portion 20a is screwed into the mounting screw hole 18a of the bracket 18 by rotating the knob portion 20b. Due to this screwing, the rear lower edge 18e of the bracket 18 is connected to the rear bent portion 1.
It slides downward along the inclined inner surface of 9c. In response to this sliding, the front horizontal member 2a of the loading platform 2 is strongly pushed deep into the hook portion 17. That is, the trunk 4 and the middle cargo platform 3 are firmly fixed to the cargo platform 2 when the threaded portion 20a and the mounting screw hole 18a are properly screwed together. The loosening of the threaded engagement between the threaded portion 20a and the mounting screw hole 18a due to vibrations, etc., occurs due to the sliding movement of the front horizontal member 2a and the hook portion 17 along the inner surface of the rear bent portion 19c of the rear lower edge 18e. Absorbed by engagement.

To remove the trunk 4 from the cargo platform 2, rotate the knob 20b of the fastening bolt 19 in the opposite direction to loosen the screwed state, separate the mounting member 19 from the bracket 18, and separate the hook part 17 from the front side. What is necessary is to release the engagement with the member 2a. in this case,
The separation between the mounting member 19 and the bracket 18 and the disengagement between the hook portion 17 and the front horizontal member 2a are easily and naturally performed without any resistance.

In addition, in this embodiment, the cargo such as a trunk and the middle cargo bed 3 are integrally attached, and the middle cargo bed 3
Although the hook part 17 and the bracket 18 are attached to the lower surface side, the same effect as in the above embodiment can be obtained even if the hook part 17 and the bracket 18 are attached directly to the lower surface side of the cargo such as a trunk. It is something.

(Effects of the invention) As described above, the invention has a hook part with an alligator-shaped front opening, and a rear end edge provided at a predetermined distance behind the hook part and extending in the left-right width direction. and a bracket having a mounting screw hole is provided on the lower surface side of the load, so that when the hook portion engages with the front horizontal member of the loading platform from the rear, the bracket is attached to the rear of the rear horizontal member of the loading platform. a front bent part whose inner surface is raised up so as to come into contact with the front end of the rear transverse member, a horizontal part connected to the front bent part and having a through hole, and a rearwardly inclined part connected to the horizontal part. A mounting member consisting of a rear bent portion whose inner surface is raised up so as to come into contact with the rear end edge of the bracket is provided, the mounting member is inserted into the through hole of the mounting member in a loosely fitted state, and is inserted into the mounting screw hole of the bracket. Since the structure is such that a fastening bolt is provided that is screwed into the horizontal part of the mounting member from the lower side, the load can be firmly fixed by simply attaching the hook part and the mounting member, which have a simple structure, to the lower surface of the load. Easy to remove.

Further, there is no need for troublesome setups for positioning the hook portion or the mounting member, and there is no need to require strict manufacturing accuracy or assembly accuracy.

Furthermore, even if the fastening bolts become loose after the loaded cargo is fixed to the loading platform, this loosening is caused by the sliding between the rear edge of the bracket and the rear bend of the mounting member, and by this sliding. Since it is absorbed by the engagement between the hook part and the front horizontal member, it does not affect the firm fixation of the loaded cargo in any way.
