According to the present invention having such a configuration, the bicycle is first stopped at a place where a wheelchair can enter, such as a front door or a garden, where a wheelchair can enter. Open the door and then grasp the handle at the center of the side slope plate from the inside and rotate the slope plate to make the upper part touch the ground to form a slope. The locking rod is folded and stuck in by a link function provided in the concave portion of the vehicle body bottom plate.

For this reason, the wheelchair that has been raised from the side plate of the side body and locked between the main wheel and the front wheel of the wheelchair is in a state where the wheelchair can be mounted on the wheelchair. When the rider mounts on the slope plate near the specified position of the vehicle body on the push-up side, then, when the slope plate is rotationally tightened again, the rear door is closed and the tightening device is completely tightened.

[0008] The rotation of the slope plate again raises the locking bar of the link mechanism between the main wheel and the front wheel of the wheelchair to lock the wheelchair. When the above operation is completed, a safety band having one end fixed to the bicycle side of the side car body is mounted near the abdomen of the care receiver, and the other end is tightened to the other side of the side car body with a fastener.

Since the preparation for departure has been completed as described above, the operator, that is, the caregiver may activate the auxiliary power while depressing the bicycle pedal to run the vehicle, or may perform a shift change by appropriately determining the road conditions. When arriving at the destination or taking a break, the caregiver stops the bicycle in a safe position and then gets off, pulls out the storage seat at the tip of the side body, and sits down to enjoy dialogue at the same eye elevation as the care recipient. You can also.
