<P>PROBLEM TO BE SOLVED: To provide a simple and inexpensive structure for attaching a driving seat to a support socket on a body side. <P>SOLUTION: A support pipe 5, which is made of a pipe material and which is formed to project on the lower surface of the driving seat 3 by jointing a flat plate 3 to the outer surface, is fitted into the support socket 2, which is made of a square pipe material having arc-shaped curved faces at four corners of the inner peripheral surface and which is erected on the upper side of the body, from the upper end of the support socket 2, and attached and supported. By tightening the support pipe 5 with a set bolt 6 penetrating from the outer side of the support socket 2, corner edges of both ends of the flat plate 3 are made to abut to the arc-shaped curved faces of the support socket 2. The seat attaching device of the electric wheelchair is characterized by tightening and fixing the support pipe 5 in this way. <P>COPYRIGHT: (C)2012,JPO&INPIT |
