BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare tire carrier device for arranging a spare tire at a rear gate of a vehicle.

[0002]

2. Description of the Related Art Recently, with the popularity of auto camps and the like, the popularity of four-wheel drive vehicles has been increasing. The four-wheel drive vehicle is most suitable for traveling on a rough road such as a mountain road, and the wheels (tires) of the four-wheel drive vehicle are designed to secure running performance on a rough road. The diameter and width of the tires are larger than those of ordinary passenger car tires, and the weight of the tire itself is considerably heavy. In addition, this kind of vehicle is equipped with spare tires similar to the wheels mounted on the vehicle body, and it is very large and it is difficult to secure the accommodation space in the vehicle body. For that reason, the spare tire is generally located at the rear gate of the vehicle. If the rear gate of the vehicle is open horizontally, the spare tire is directly mounted on the rear gate. Therefore, a frame-shaped carrier that can be opened and closed in the front-rear direction of the vehicle is provided on the rear bumper, and a spare tire is mounted on the carrier.

A conventional example of a carrier device for a spare tire will be described with reference to FIGS. Vehicle 1 shown in FIG.
Has a rear gate 2 which can be rotated up and down, and a carrier for a spare tire is arranged in the rear gate portion. As shown in FIG. 1, the carrier device for a spare tire includes a pipe frame 3 curved in an arc shape. Both ends of the pipe frame 3 are directed downward, and an auxiliary pipe 4 is passed between these ends to connect them.

[0004] One end of the pipe frame 3 is connected to a bracket 6.
The bracket 6 is provided inside the rear bumper 5. According to FIG. 2, one end of the pipe frame 3 is inserted into the bracket 6 and is fixed from below by bolts 8 via washers 7. On the other hand, the other end of the pipe frame 3 is connected to the rear bumper 5 via a lock device (not shown). The lock device includes a fork pin type lock mechanism, and is detachable from a striker (not shown) provided on the rear bumper 5. In the center of the pipe frame 3,
A bracket 9 is provided, and a spare tire is mounted on the bracket 9.

[0005] Therefore, the spare tire carrier can be opened and closed between an open position opened toward the rear of the vehicle and a closed position along the rear bumper. When the carrier is opened from the closed position, the locking device is unlocked with a key, and then the pipe frame of the carrier is pulled directly by hand.

[0006]

However, in the case of the above-described carrier device for a spare tire, it is merely a combination of a pipe frame and a lock device, which is not very desirable in appearance, and the carrier is opened from a closed position. In some cases, the lock device must be released with a key, and then the pipe frame of the carrier must be directly held by hand and pulled.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a carrier device for a spare tire which has a good appearance and can be opened and closed by a simple operation.

[0008]
