The present invention relates to a wheel carrier holding device for a bicycle carrier used by being fixed to an automobile.

As a wheel holding structure in a bicycle carrier used by being fixed to a conventional automobile, for example, as disclosed in US Pat. No. 5,570,825, a U-shaped support member 300 for receiving a bicycle wheel from below, A wheel holding device is known that includes a belt 301 that presses a bicycle wheel downward so that the bicycle wheel does not detach from the support member, and a lock mechanism 302 of the belt 301. (Fig. 39)

In addition, as a stand for fixing the wheel 310 of an automobile (for example, a motorcycle), the inclined plate 311 pivotally supported on the lower surface is rotated by the operation of inserting the wheel 310 in the front-rear direction, and interlocked with the operation. US Pat. No. 5,735,410 is known as a mechanism for actuating the front tire engagement support 312 and the rear tire engagement support 313 in the sandwiching direction of the wheel 310 from the left and right. (Fig. 40)

However, in the technique disclosed in the above-mentioned US Pat. No. 5,570,825, when the bicycle is loaded on the carrier, the belt 301 disposed on the upper portion of the U-shaped support member 300 becomes an obstacle, and the work is performed. The performance was significantly reduced. Further, when passing the belt 301 through the wheel, it is necessary to pass the belt 301 from the opposite side of the wheel or from the front side of the wheel to the back side, so that it takes time to work, and by touching the wheel during the work, There was a problem of getting hands and clothes dirty. In addition, since the U-shaped support member 300 is formed with a width of about 60 mm so that it can be loaded even on a bicycle with a large wheel diameter such as a mountain bike, it is used when holding a bicycle with a small wheel diameter such as a road bike. Occasionally, the bicycle wheel moved in the left-right direction with respect to the U-shaped support member 300, resulting in a lack of stability, and there was a risk that the bicycle holding state was loosened due to repeated left-right movement.

In the technology disclosed in the above-mentioned US Pat. No. 5,735,410, since it is fixed in conjunction with the vehicle's own weight, when this technology is used for a carrier, it may be caused by factors such as vehicle shaking. There is a concern that the sandwiched state of the wheel 310 between the rear tire engagement support 312 and the rear tire engagement support 313 may be released.
