Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the floor of a truck bed, which is a vertical joist (11) placed on a chassis frame.
And the horizontal joist (12) passed at a right angle to the vertical joist (11), and the horizontal joist
A floorboard (13) supported by (12) and a floor frame around the floor
It has (14) and a rope hook (17).

The floor frame (14) comprises front and rear side frame members (15) and left and right side frame members (16) made of extruded aluminum (including aluminum alloy). As shown in FIGS. 2 and 3,
The left-right frame member (16) has a main body (21) having a substantially U-shaped cross section, which is composed of an upper wall (21a), a lower wall (21b) and a vertical wall (21c). The wall (21b) is provided with an internal expansion groove (22) extending in the longitudinal direction and opening downward.

The outer wall portion (22a) of the internal expansion groove (22) and the main body (21)
It is flush with the vertical wall (21c) of this and this part acts as a drain for rainwater.

The rope hook (17) has a horizontal base (17a) having a bolt hole (18). This rope hook
When attaching (17) to the left and right side frame members (16), insert the bolt head (23a) into the internal expansion groove (22) and insert it to the position where the rope hook (17) is attached. Insert the bolt shank (23b) into the bolt hole (18) of the horizontal base (17a) of the rope hook (17), and then nut the bolt shank (23b).
Fit (24) and tighten. This allows the rope hook (1
7) is fixed to the left and right frame members (16). Bolt head (23a)
By changing the position to insert the left and right side frame members
The rope hook (17) can be attached at any position of (16). Further, by providing an internal enlarged groove in the rear frame member (15), the rope hook (17) is similarly made to the rear frame member.
Can be attached to (15).

FIG. 4 shows a modified example of the rope hook (31). At the base of the rope hook (31), there is a hook rotation prevention part that is movably fitted into the internal expansion groove (22).
(32) is provided, and the thread is attached to the vertical part of the rope hook (31).
(31a) is provided. The male thread (31a) has a nut (3
3) is screwed.

In this embodiment, the hook rotation preventing portion (32) of the rope hook (31) is a rectangular plate having a screw hole and is detachably attached to the male screw portion (31a). There is. The shape of the hook rotation preventing portion (32) is not limited to a square shape, and may be any other shape as long as it has two sides having a width smaller than the width of the internal expansion groove (22), For example, a hexagon nut may be used. In addition, the hook rotation prevention part (32) of the rope hook (31) is
May be integrally provided in the.

The rope hook (31) is connected to the left and right side frame members.
When attaching to the (16), insert the hook rotation prevention part (32) of the rope hook (31) into the internal expansion groove (22), insert it to the position where the rope hook (31) is attached, and tighten at this position. Tighten the nuts (33). This allows the rope hook
