Abstract:
PROBLEM TO BE SOLVED: To provide a frame fastening structure enabling a fastening part to have sufficient strength, even without using welding.SOLUTION: In a frame 40 of a wheel chair 10, pipe members are fastened around bodies 50 positioned on both side portions of the wheel chair 10. In a fastening structure of the frame 40, the pipe members (a backrest pipe member 61, and a footrest pipe member 62) are connected to the body 50 through intermediate members composed of fixing members 51b and 52b of fastening members 51 and 52, so that two or more pipe members can be fastened to the intermediate members, and each of the pipe members can be coupled. Even if sleeve members 51a and 52a are pressed in from the outside, auxiliary members 512 and 522 are pressed in the inside of cylinder portions 511a and 521a to make the cylinders 511a and 521a have sufficient strength for fastening the sleeve members 51a and 52b, so that the pipe members are not deformed inward.SELECTED DRAWING: Figure 4
