First, the mounting structure of the grab bar 13 will be explained. The grab bar 13 is constructed by bending a pipe material into a substantially U-shape, and has a hollow support shaft 15 and a sector-shaped locking plate 16 provided at both ends thereof. The respective support shafts 15 are arranged on the same axis, and each locking plate 16 is provided to intersect with each support shaft 15.
A pair of locking holes 17a and 17b are bored in the locking plate 16 on the axis a of both ends of the grab bar 13 and at a portion displaced by 90 degrees with respect to the axis b of the support shaft 15. A U-shaped storage groove 18 in which the grab bar 13 can be stored face down is formed on the upper surface of the rear carrier 10, and the support shafts 15 at both ends of the grab bar 13 are attached to bearing brackets 19 provided at both ends of the storage groove 18.
are supported respectively. The support shaft 15 is fixed to the bearing bracket 19 by a pin 20 inserted therein, a washer 21 and a locking pin 22 attached to the pin 20. The grab bar 13 can be raised or laid down on the rear carrier 10 by rotating around the support shaft 15.

The grab bar 13 can be stopped at various up and down positions by a stopper mechanism 23. That is, the stopper mechanism 23 is
As shown in the figure, there is a support bracket 24 fixed to the inside of the upper wall of the rear carrier 10, an operating lever 26 rotatably attached to the bracket 24 via a pin 25, and a supporting bracket 26 attached to both ends of the operating lever 26, respectively. 1 rotatably connected via a pin 27
A pair of locking rods 28 and each of these locking rods 28

It is composed of: Each of the locking rods 28 of the stopper mechanism 23 faces the locking holes 17a and 17b of the locking plate 16 provided at both ends of the grab bar 13, and the tips of the rods are locked by the elastic force of the tension coil spring 29. Insert into hole 17,
The locking plate 16 and, in turn, the grab bar 13 are prevented from rotating. Rotate the operating lever 26 to move both locking rods 28 in the proximal direction (arrow B
direction), the tip of the rod is pulled out from the locking hole 17, and the grab bar 13 becomes rotatable. Note that the locking holes 17a and 17b are connected to the support shaft 1.
5, the grab bar 1 stands up approximately vertically from the rear carrier 10, and rotates 90 degrees to move into the storage groove 18.
It is set to a position where it is stored face down inside the body, and it can be selectively fixed to each of these positions.

Next, the mounting structure of the rear seat 14 will be explained. The rear seat 14 has a shape that can be combined with the rear part of the front seat 30. A pair of left and right hooks 31 are provided at the lower front end of the rear seat 14, and left and right hooks 31 are provided at the front end of the rear carrier 10.
It is designed so that it can be hooked into a pair of bolt mounting holes 32, respectively. Further, a substantially U-shaped seat lock bar 33 is provided at the bottom of the rear end of the rear seat 14 so as to protrude with its intermediate portion facing downward. This seat lock bar 33 can be inserted into a hole 34 on the rear end side of the rear carrier 10 and is locked into a seat lock mechanism 35 provided inside the rear carrier 10. That is, the seat lock mechanism 35
A lock plate 38 is integrally attached to a shaft 37 supported via a bracket 36, and a hook portion 38a of this lock plate 38 faces the hole 34. And axis 3
7 is designed to lock the inserted seat lock bar 33 by positioning the hook portion 38 of the lock plate 38 in a horizontal position using a locking tool. By rotating a lever 40 provided at one end of the shaft 37, the seat lock bar 33 is released and the rear seat 14 can be pulled upward and removed.

According to the configuration of the above embodiment, the rear seat 14
When installing the grab bar 13, it is sufficient to place the grab bar 13 face down in the storage groove 18 of the rear carrier 10, so there is no problem of the grab bar 13 getting in the way as in the conventional case. Therefore, a sufficiently long rear seat 14 can be used, and a simple structure with a flat seat bottom can be achieved.

Particularly in the case of the embodiment, the grab bar 13 can be fixed and released by rotating the operating lever 26, so there is an advantage that the grab bar can be easily raised and lowered on the rear carrier 10. Further, this stopper mechanism 23 has a compact structure including an operating lever 26, a locking rod 28, a tension coil spring 29, etc., and is mounted by effectively utilizing a narrow space within the rear carrier 10. Therefore, the size of the seat portion does not become unnecessarily large. Moreover, according to the above-mentioned stopper mechanism, one tension coil spring 29 allows the pair of locking rods 2
8 are energized at the same time, the number of parts is small and the configuration is compact.

In addition, if the rear seat 14 is not installed,
The grab bar 13 may be erected above the rear carrier 10, and the locking rods 28 may be inserted into different locking holes 17b of the locking plate 16.

In the above embodiment, both ends of the grab bar 13 are locked by the stopper mechanism 23, but in the present invention, only one end of the grab bar 13 may be locked.

FIG. 7 shows an example of such a configuration, in which a locking plate 16a similar to that of the previous embodiment is provided only on one end side of the grab bar 13. One locking rod 28a connects to the other bearing bracket 19b from one bearing bracket 19a that supports the other end of the grab bar 13 without the locking plate 16a.
It is inserted on the side. This locking rod 28a is provided with a washer 41 and a locking pin 42, and this washer 41 and one of the bearing brackets 19a
