おそれがあった。That is, the rear floor (1) of the car is recessed to form a storage area (3) for the spare tire (2), and a projection weld nut is installed on the top surface (4υ) on the bottom surface (01) of the storage area (3). (5) is fixed, leg +421.(47
A holding bracket (4) with a curved mounting surface (4 widths and 4 stories) is fixed by spot welding to the lower end of J.Then, a holding bolt (6) inserted through the spare tire wheel (211) The spare tire (2) is held by being screwed onto the nut (5) of the holding bracket (4). , (B) is a fuel tank. However, in the conventional spare tire holding structure described above, when an impact is applied from the rear of the vehicle (in the direction of arrow (C) in Figure 1), the energy is transferred to the storage section (3). ) even if the spare tire (2) is firmly held by the holding bracket (4), the spare tire (2) will not fit into the housing (3).
) and remains in the storage part (3), and when the storage part (3) deforms, the spare tire (2) acts as a rigid body, preventing the storage part (3) from deforming effectively. There was a possibility that sufficient energy absorption would not be possible. Therefore, the impact is directly transmitted to the seat retainer and the fuel tank (3) disposed in front of the storage section (3), which may cause damage to the occupants or damage such as fuel leakage.
本発明は、上記従来の問題点に着目して４ｆされたもの

ヤが収納部から脱出できるようにしたものである。In order to achieve this object, in the present invention, the rear floor of the vehicle body is recessed to form a storage section, and a retaining bolt that is screwed into a nut of a retaining bracket fixed to the bottom of the storage section is provided as a spare. In a structure in which a spare tire is held by being inserted through and fastened to a tire wheel, the holding bracket is formed with a nut holding part that is opened toward the front of the vehicle body, and the nut is attached to the nut holding part so that the nut is not attached to the vehicle body. The spare tire is held in place by a structure that allows it to be held in the front in a removable manner.In the event of a rear impact, the nut holding part separates from the nut, causing the spare tire to be released from the holding bracket and the spare tire to be removed. It is designed to allow escape from the storage section.
以下、図示実施例に基づき本発明を説明する。The present invention will be explained below based on illustrated embodiments.

、切欠孔（４５１の開放側より挿入されている。3 and 4 show a first embodiment of the present invention, in which the positional relationship between the storage section (3) and the holding bracket (4) is the same as that of the conventional example, but the upper surface of the holding bracket (4) (4]) is formed with a nut holding part (46) with a notch hole (46) that opens at the front. On the other hand, a nut (5) is fixed to the lower surface of the lower piece (7). At the same time, the upper piece (71) and the lower piece (7) are bent into a substantially U-shaped cross section, and a bolt insertion hole (73) is bored in the upper piece qυ and the lower piece (7). ) and the lower piece (72), the clamp (7) whose tip side is closed by the spring action, clamps the upper surface (4I) of the holding bracket (4) between the upper piece (71) and the lower piece ff2), and the notch hole (451 and bolt insertion hole (7 (support)
and the screw hole 5] of the nut (5) are inserted from the open side of the notch hole (451).

is formed, a holding plate (62) is fixedly installed in the middle part, and a handle (63) is provided at the rear end. When holding the spare tire (2), the holding bolt (6) is attached to the spare tire wheel. (Insert into the 2+1 insertion hole (221, Il;j, bolt insertion hole (73) of the clamp (7),
The bolt part (61) is screwed into the screw hole 61 of the nut (5) through the notch holes (6) of the nut (5), and is tightened by being rotated by the handle (63). The spare tie-rt2) is held by pressing the spare tire wheel (21). This pressing force is applied to the handle (

る。When the spare tire (2) is held in place, if a force is generated that moves the spare tire (2) forward due to an impact caused by a rear collision of a car, etc., the force is transferred from the spare tire wheel (21) to the spare tire (21). The force is transmitted to the holding bolt 6 through the insertion hole (731 edge) of the tire wheel c21), and the holding bolt (6) attempts to push the nut (5) and clamp (7) forward. The tightening force of the nut (5) is about human power and is not very large, so the force moves forward with the holding bolt (6), the nut (5), and the clamp (the force moves forward. Therefore, the bolt part (6])
When they move, there is no hooking force, and they eventually separate from the nut holding part (46). Now, the spare tire (2) is no longer held, so it escapes from the storage section (3) and no longer restricts the deformation of the storage section (3).
The storage portion (3) is effectively deformed and the impact energy is absorbed.

。5 and 6 show a second embodiment of the present invention, in which a notch hole (45) opened forward is bored in the upper surface (4I) of the retaining bracket (4), and the nut retaining portion is The structure is similar to that of the first embodiment, but the nut (5) is fixed to the lower surface of the insertion plate (8), and the nut holding part (
46), an inward cut is made on the lower side of the upper surface (41) in 471. (47) is formed, a forward-facing claw portion (48) is formed on the lower side of the rear end, and the nut (5) is attached to the insertion plate (
8) is cut downward from the top surface (41) and 47), (47
), and is held by being supported and inserted by the claw portion (48). The spare tire (2) is held by a holding bolt (6) as in the first embodiment.
