っている。2. Description of the Related Art In a vehicle equipped with a chassis frame, if a towing hook is attached to the center of a rear cross-end pipe extending in the vehicle width direction and connected to the left and right chassis frames, the strength of the chassis frame is increased. Although it is possible to increase the pulling load of the hook by using a monocoque body structure for off-road vehicles in recent years, the monocoque body structure has to be thinner than the chassis frame made of thick plates. Because of the laminating structure used, the strength of the hook attachment portion and the like is relatively weak, and thus it is difficult to attach a pintle hook having a large traction force.

シャシフレームと比較して低くなりすぎる欠点がある。A hook mounting device for a vehicle body having a monocoque structure exemplified in Japanese Patent Application Laid-Open No. 7-17430 discloses a hook bracket having a substantially U-shaped cross section. The bottom wall portion and the bottom wall portion of the rear end cloth constitute a closed cross-sectional structure, and an L-shaped hook bracket of the towing hook is arranged from one side surface to the bottom surface of the hook bracket. In this case, , A hook bracket having a substantially U-shaped cross section is connected to one of the rear side members and the rear end cross located on the left side of the vehicle, and the connection portion is limited to a narrow range, so that the strength of the attached towing hook is small. However, there is a disadvantage that it is too low as compared with the chassis frame.

れている。Therefore, a vehicle hook mounting device according to the present invention comprises a pair of frames respectively disposed on the left and right sides of the vehicle and extending in the vehicle front-rear direction.
In a vehicle having a cross member extending in the vehicle width direction and having both ends connected to respective ends of both frames, and a floor panel connected to upper surfaces of both frames,
Left and right support members connected to the inside of the left and right frames in the vehicle width direction and the lower surface of the floor panel and extending rearward from below the cross member, and the left and right support members extending in the vehicle width direction and having both left and right ends. A cross member connected to an end of the member is provided, and a towing hook is attached to an intermediate portion of the cross member in the vehicle width direction.

とができる。As described above, the left and right support members are connected to the inside of the left and right frames in the vehicle width direction and to the lower surface of the floor panel, respectively. Since the connection range is wide, the holding strength of the support members is large. The cross member having both ends connected to the end of the support member is firmly supported by the left and right support members, and the cross member is disposed between the left and right frames, and the span in the vehicle width direction is relatively small. Since it is small, the strength of the cross member is relatively large with respect to the load acting on the intermediate portion in the vehicle width direction, so that the traction load of the hook attached to the cross member can be easily increased.

重支持剛性を効率よく高めることができる利点がある。That is, the left and right support members 3 respectively support the load in the vehicle front-rear direction by being connected to the rear end cross member lower surface 11 from the rear, and then shear the vertical load by being connected to the rear end cross member front surface 10. To support the load and moment in the vehicle front-rear direction by connecting to the lower surface of the floor panel 6, and to support the load in the vertical direction by connecting to the inner side surface of the left and right rear frames 1 in the vehicle width direction. And the supporting member 3
The overall length of the connecting portion between the vehicle and the vehicle body can be made relatively large, and each of the connecting portions has a load support in the vehicle front-rear direction and a load support in the vertical direction alternately arranged, so that the rear portion of the support member 3 There is an advantage that the load support stiffness in the vehicle front-rear direction and the vertical direction can be efficiently increased.

たせることが可能となる。Further, since the left and right support members 3 are connected to the lower surface of the floor panel 6, the upper flanges 5 which extend from the left and right rear frames 1 and extend toward the rear end cross member 2 are relatively wide. Due to the plane portion of the range, the load acting on the support member 3 can be efficiently supported, and therefore the support member 3 can have sufficient support force without increasing the thickness of the support member 3 and the like.

荷に対する強度が相当に大きくなっている。For this reason, the cross pipe 15 whose both ends are fixed to the left and right support members 3 is very firmly supported by the left and right support members 3 and the like, while the right and left ends of the cross pipe 15 are respectively left and right supported. Since the support span of the cross pipe 15 in the vehicle width direction is fixed to the rear end portion of the member 3 and the support span of the cross pipe 15 in the vehicle width direction is relatively short, the load of the towing hook 17 attached to the central portion of the cross pipe 15 via the attachment plate 16 is reduced. The strength is considerably higher.
