PROBLEM TO BE SOLVED: To provide a safety traveling device for solving problems in which a wheelchair retreats when climbing a slope in the wheelchair and a user stops its motion, however a conventional retreat prevention device cannot be operated easily, and also a sharp turn is not made in the turning.SOLUTION: A traveling safety device of the present invention includes an engaging teeth member mounted to a drive wheel, a swinging claw member provided in the vicinity of an armrest, and an operating lever arranged up of the swinging claw member. The traveling safety device swings the swinging claw member by the operating lever, and changes an engagement state of the engaging teeth member and the swinging claw member, and thereby the retraction when climbing a slope is prevented. Further, a drive wheel can be braked by the operating lever. Also, the traveling safety device of the present invention has the engaging teeth rotating along with a differential case in the differential gear, and a swinging claw arranged to the engaging teeth, and also is connected to the axle of the left and right drive wheels, and therefore is superior in turning performance.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】車椅子等において坂を登るときに利用者が動作を止めると後退してしまう。従来の後退防止装置は容易に操作することができない。また、旋回時に小回りができない。【解決手段】本発明の走行安全装置は、駆動輪に装着される係合歯部材と、アームレスト近傍に設けられた揺動爪部材と、前記揺動爪部材の上方に配される操作レバーを備え、前記操作レバーにより前記揺動爪部材を揺動させて前記係合歯部材と前記揺動爪部材の係合状態を変化させることにより、坂を登るときの後退を防止する。さらに操作レバーにより駆動輪を制動することができる。また、本発明の走行安全装置は、差動歯車におけるデフケースとともに回転する係合歯と、前記係合歯に対して配される揺動爪を有し、左右の駆動輪の車軸に接続し、旋回性に優れる。【選択図】図1
