If necessary, a second cargo carrier 94 having the same structure and spaced apart from the cargo carrier 92 may be rotatably provided on the cargo shelf 40 of each of the 2 vehicle tailracks C1, C2.

Fig. 4 is a perspective view showing an application example when the second cargo holder 94 is added. As shown in the drawing, after the cargo holder 92 and the second cargo holder 94 are spread apart from each other, the front wheel and the rear wheel of the bicycle are clamped to the cargo holders on both sides, and the frame of the bicycle is fixed by the clamp 72 of the fixing unit 70, which will be described later, so that the bicycle can be safely set to the tail stock device.

Further, at a position between the cargo bracket 92 and the second cargo bracket 94, an inverted L-shaped fixing unit 70 is rotatably provided to each cargo shelf 40, and a clip 72 is provided at an end of the fixing unit 70. In this case, as shown in fig. 4, the bicycle can be fixed using the clip 72, or, as described below, one side of a snowboard fixed with a double-board or a snowboard fixed with a single board can be clamped by the clip 72, thus being very convenient. When the goods are not loaded, the fixing unit 70 may be laid down (see fig. 1).

As shown in fig. 2A and 2B, at the location of the pivotal connection of the cargo brackets 92 of the tailstocks C1, C2, the linear handle crossbar 60 can be coupled to the cargo shelves 40 on either side by traversing each cargo shelf 40 at right angles to each cargo shelf 40. The handlebar crossbar 60 acts as a stop to prevent further rotation of the cargo carrier 92 when the cargo carrier 92 is upright, supporting the handlebar of the bicycle when the bicycle is inverted. If a plurality of handle fixing units 62 for coupling with the handle bars of the bicycle are provided at the handle bar 60, the handle bar portion of the bicycle can be tightly clamped by the fixing units 62.

Further, a linear crossbar 80 may be provided laterally at one end position of the cargo shelf 40 of each of the 2 vehicle tailstocks C1, C2.

Round wheels 82 made of an impact absorbing material are rotatably provided on both sides of the

crossbar

80, 2 cushioning materials 84 made of an impact absorbing material are rotatably provided between the round wheels 82 provided on both sides on the crossbar 80, one end of each cushioning material 84 is formed with a concave-convex surface, and a suction unit 86 is provided on the opposite side of the concave-convex surface. As shown in fig. 5B, when the light article is mounted on the tailstock apparatus, the uneven surface of the cushion material 84 faces the ceiling of the vehicle. In this case, the cushioning material 84 and the round wheels 82 are both spaced from the ceiling of the vehicle due to the light weight of the article. As shown in fig. 5C, when a heavy article is loaded on the tail stock, if the suction unit 86 is directed to the ceiling of the vehicle by rotating the cushion material 84 by 180 degrees, the suction unit 86 is sucked to the ceiling of the vehicle, and the article can be supported more stably without rattling.
