Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a fuel tank mounting structure.

<Prior Art> Conventional fuel tank mounting structures include, for example, those shown in FIGS. 8 and 9.
-93521 gazette).

Numeral 1 is a fixed pin, and both ends of it are heads to prevent falling.
Have 1a. And 2 is a fixed bracket,
It has a pair of left and right bracket plates 3 and 4 facing each other. The left and right bracket plates 3 and 4 are respectively formed with horizontal notches 3a and 4a for inserting the fixing pin 1 and diagonal notches 3b and 4b continuous with the horizontal notches 3a and 4a. Then, the horizontal notches 3a, 4a for insertion in the left and right bracket plates 3, 4
Are arranged in different steps from the standpoint of preventing falling. And
Reference numeral 5 is a belt member, one end of which is locked to the fixing bracket 2 by the above-mentioned fixing pin 1 and the other end of which is attached to the vehicle body by a fastening means such as a bolt.
To the underside of the vehicle.

Further, another conventional example is shown in FIG.
2625 gazette).

6 is a fixing pin, a through hole for inserting and fixing a head 6a at one end and a split pin 7 for preventing the drop at the other end
6b is formed. Reference numeral 8 denotes a fixed bracket, and a pair of left and right bracket plates 9 and 10 facing each other have round holes 9a and 10a through which the fixed pin 1 is inserted. Further, 11 is a belt member, and the fuel tank F is attached to the lower surface of the vehicle body by this belt member 11 as in the above-mentioned example.

<Problems to be Solved by the Invention> However, in the first example described above, the fixing pin 1 is inserted in an incomplete state (indicated by a chain double-dashed line in FIG. 9), though it has the advantage of being inexpensive and having good workability. Since it is difficult to find the fixed pin 1 even if it is in a state), there is a problem that it takes man-hours to check whether or not the fixing pin 1 is completely inserted.

In addition, in the following example, although the imperfect insertion of the fixing pin 6 can be prevented, the fixing pin 6 must be inserted into the round holes 9a and 10a that are difficult to insert, and the split pin 7 for preventing the falling must be attached. Since it does not happen, workability was poor.

Therefore, the present invention solves the above-described problems and provides a fuel tank mounting structure in which a reliable belt member can be easily mounted and the mounting state of the belt member can be easily checked.

<Means for Solving the Problems> In order to achieve the above object, the fuel tank mounting structure according to the present invention has a pair of bracket plates mounted in a state of facing the vehicle body, each having an insertion hole for inserting a fixing pin. And a fixing hole for preventing the fixing pin from falling off are continuously formed, and one end of the belt member inserted between the brackets is locked by the fixing pin inserted into the insertion hole, and the fixing pin is fixed to the fixing hole. The other end of the belt member that is rotated around the fixing pin and is locked to the vehicle body,
In a fuel tank mounting structure in which a fuel tank is mounted on a lower surface of a vehicle body with the belt member, a claw portion protruding in a width direction beyond a distance between the pair of fixed bracket plates is provided near one end of the belt member, and The distance from the center of the fixing pin inserted into one end of the belt member to the claw portion is within the rotation range of the belt member from the center of the fixing pin located in the fixing hole to the farthest point of the bracket plate. It is slightly larger than the distance.

<Operation> According to the fuel tank mounting structure of the present invention,
A claw portion protruding in the width direction of the belt member is provided near the fixing pin attachment position of the belt member, and the width of the belt member is formed to be larger than the bracket plate interval. Then, only when the fixing pin is located in the fixing hole and only when it is completely inserted, the claw portion of the belt member does not get caught on the bracket plate and can be rotated in the regular belt member mounting direction from the insertion direction, so that the fixing pin to the claw portion can be rotated. The interval was set. Therefore, the fixing pin is incompletely inserted (the fixing pin is not in the fixing hole)
At this time, since the claw portion of the belt member is caught on the bracket plate, the belt member makes a detour from the regular mounting position, and the end of the belt member opposite to the fixing pin does not reach the mounting position on the vehicle body. This makes it possible to easily detect that the fixing pin is in the incompletely inserted state.

<Examples> A preferred example of the present invention will be described below with reference to FIGS. 1 to 7.

F is a fuel tank, and 20 is a belt member.
As shown in FIG. 2, the belt member 20 is made of a rigid material that does not expand or contract and has a shape corresponding to the shape of the lower surface of the fuel tank F. And the fixing pin 21
There is a winding part 20a for use, and both bracket plates 22, 22 which will be described later and project in the width direction of the belt member 20 near the winding part 20a.
A claw portion 23 for restricting the rotation of the belt member 20 is provided so as to be wider than the interval. The other end of the belt member 20 is formed with a through hole 20b for bolting to the mounting bracket 24 of the vehicle body. The fixed pin 21 has heads 21a and 21b at both ends thereof, and one head 21b
Has a thin tip so that the belt member 20 can be easily inserted into the winding portion 20a (see FIG. 3).

25 is a fixing bracket fixed to the lower surface of the vehicle body. The fixing bracket 25 has the pair of opposed bracket plates 22 and 22 described above, and the bracket plate 22 has an insertion hole for inserting a fixing pin having a diameter larger than at least the head 21b of the fixing pin 21. 22a and a fixing hole 22b which is continuously provided and has a diameter smaller than the head portions 21a and 21b but larger than the shaft portion 21c are formed through an introduction portion 22c (length m). Here, m is the fixed pin 21
Is set to be sufficiently longer than α (indicating the gap between the edge of the bracket plate 22 and the claw portion 23) so as not to fall off (see FIGS. 5 and 6). Then, the belt member between the inserting direction of the belt member 20 (direction A in FIG. 3) and the regular mounting direction of the belt member 20 (direction B in FIG. 4).
In the rotation range R of 20, a claw portion 23 is formed at a position L from the center of the fixed pin 21 so as to satisfy the relationship of L = 1 + α (see FIGS. 5 and 6). Here, 1 represents the distance from the fixed pin 21 in the completely inserted state to the farthest point of the bracket plate 22 in the rotation range (between the belt member 20 insertion direction and the regular belt member 20 mounting direction) R. .

Next, the procedure for attaching the fuel tank F using the belt member 20 will be described.

One end of the belt member 20 is inserted between both bracket plates 22 of the fixed bracket 25, and the fixing pin 21 is inserted into the winding portion 20a of the belt member 20 through the insertion hole 22a of the bracket plate 22.
Then, the fixing pin 21 is pulled down from the insertion hole 22a to the fixing hole 22b through the introduction portion 22c, and the belt member 20 is set in a completely inserted state (a state in which the fixing pin 21 is located in the fixing hole 22b) (FIG. 3). And FIG. 4). In this way, when the fixing pin 21 is pulled down to the fixing hole 22b, it is in a completely inserted state, so as shown in FIG. 4, from the position indicated by the chain double-dashed line to the position indicated by the solid line (regular belt member mounting position). It becomes rotatable. Next, the other end of the belt member 20 is bolted to the mounting bracket 24 of the vehicle body.

In this way, the claw portion 23 is provided in the vicinity of the mounting position of the fixing pin 21 of the belt member 20, and only when the fixing pin 21 is completely inserted, the belt member 20 is inserted from the insertion direction (direction A in the figure) to the normal mounting direction ( Since the fixing pin 21 is incompletely inserted, the claw portion 23 of the belt member 20 is caught by the bracket plate 22 and makes a detour (see FIG. 7). , The opposite end of the belt member does not reach the mounting bracket 24 of the vehicle body. As a result, it is easily recognized that the fixing pin 21 is in the incompletely inserted state, so that the check process is unnecessary and the number of steps can be reduced.

In the above embodiment, the belt member 20 is made of a rigid and rigid material as the belt member 20, but the invention is not limited to this, and if the claw portion 23 is rigid, the other portions are not elastic and flexible. The same effect can be obtained by using a member.

<Effects of the Invention> The fuel tank mounting structure according to the present invention has the contents described above, and the belt member is provided near the fixing pin mounting position of the belt member only when the fixing pin is completely inserted. The claw portion for restricting the rotation of the belt member is provided at a position where it can rotate in the regular belt member mounting direction from the insertion direction. Therefore, when the fixing pin is in the incompletely inserted state, the claw portion of the belt member is caught on the edge of the bracket plate, and the other end portion of the belt member does not reach the fixing position to the vehicle body. As a result, it is possible to easily confirm whether or not the fixing pin is in the completely inserted state, so that the check process is unnecessary and the number of steps can be reduced.
