PROBLEM TO BE SOLVED: To provide a walking aid vehicle that is stable, safe, and well-designed.SOLUTION: This is a vehicle in which a person walks by coming in between the front wheel and the rear wheel to operate. A tricycle vehicle reduces the price but stability deteriorates, so that four wheels are better depending on the bodily conditions. Even with four wheels, changing directions by casters is likely to cause moving in a zigzag. Operating the front wheels with a handle is therefore preferable even with a higher price. For the prevention of tripping when entering the vehicle, the front and the rear wheels are designed to be connected only on one side of the vehicle.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】安定して安全、かつデザインの良い歩行補助車を提供する。【解決手段】前輪と後輪の間に人が入って操作して歩行する車とする。3輪にすると安価になるが安定が悪くなるので、体の条件によって4輪が良い。4輪でも、キャスターで方向を変えるのはジグザグ移動になりがちなので、高価になってもハンドルで前輪を動かす方法が良い。車に入るに際してつまずかないように、前輪と後輪の連結は車体の片側でのみする構造とする。【選択図】図1
