The seat portion 32 is where a child's buttocks that rides on the child seat 31 is placed, and the backrest portion 33 is where the child leans back. Both side walls 34 and 34 protect the child's side body from the outer periphery, and the handle 35 is where the child holds the hand. The foot protection cover 36 prevents the child's foot from being caught in the rear wheel 4.

  As described above, the bicycle carrier 1 according to the present embodiment includes the carrier main body 12, the front support member 13, the rear support member 14, and the intermediate support member 15, and includes the front support member 13 and the frame 3 in the vicinity of the saddle 5. The rear support member 14 and the rear wheel axle 11 are connected, and the intermediate support member 15 and the intermediate portion of the back fork 10 are connected.

For this reason, since the bicycle carrier 1 is supported by the bicycle 2 by the front support member 13, the rear support member 14 and the intermediate support member 15, for example, a child seat 31 is mounted on the bicycle carrier 1, and a child is placed on the child seat 31. Even in a loaded state, it can sufficiently withstand the load.
Further, the cargo bed body 12 includes a reinforcing frame 21 at the lower part thereof. The reinforcing frame 21 is fixed to the lower side of the outer peripheral frame 16 by welding at the top portion 23 and both side end portions 24 and 24 of the handle portion 22. Since the reinforcing frame 21 is supported by the intermediate support member 15 from below, the load applied to the bicycle carrier 1 is supported by the back hawk 10 via the intermediate support member 15, and the bicycle carrier 1 is much larger. It can withstand the load.

  Further, the reinforcing frame 15 integrally has a handle portion 22 at the rear portion thereof. Therefore, even when a child is placed on a heavy load on the bicycle carrier 1, for example, a child seat 31 attached to the bicycle carrier 1, the rear portion of the bicycle 2 can be lifted in a stable state so that the fingers can be easily put on the handle portion 22. It can be made safe and easy when the stand 2a of the bicycle 2 is upright (5b), and can be made safe and easy even when the stand 5a is jumped up from the upright state (5b). For this reason, even when heavier things are placed on the bicycle carrier 1, it can be used to withstand the load.

Furthermore, as shown in FIG. 5, the upper surface of the bicycle carrier 1 on which the child seat 31 is mounted is blocked by the child seat 31, but fingers can be put on the handle portion 22 of the auxiliary frame 21. For this reason, the rear part of the bicycle 2 can be lifted in a stable state where it is easy to put a finger on the handle portion 22, and the stand 5a of the bicycle 2 can be safely and easily raised (5b). It is possible to make it safe and easy even in a state of jumping up from the state (5b) where the head is standing.
Furthermore, since the fingers can be hung on the auxiliary frame 21, the bicycle 2 can be maintained in a stable state, and the child can get on and off the child seat 31 safely.
As described above, the bicycle 2 fitted with the bicycle carrier 1 can withstand safe and easy use even if the child seat 31 is attached to the bicycle carrier 1.
