The object of the present invention is to provide a wheelchair whose width can be adjusted. Said wheelchair having a pair of side frames connected to each other by one or more X-frame(s) ( 11 ) wherein said X-frame ( 11 ) consists of a pair of rotatable arms connected rotatably to each other at their respective centers, the lower ends of each rotatable arm being fixed to said side frame, and the fixing position of each rotatable arm to said side frame is vertically adjustable. In said wheelchair ( 1 ), when said rotatable arm(s) ( 11 A, 11 A) of said X-frames(s) ( 11 ) rotate around the centers C of said rotatable arms ( 11 A, 11 A), the width between said side frames ( 3,3 ) can be adjusted. When said rotatable arm(s) ( 11 A, 11 A) are respectively rotated, the height of said X-frame(s) ( 11 ) is changed, however, since the lower part(s) of said X-frame(s) ( 11 ) is(are) fixed to said left and right side frames ( 3,3 ), and are vertically adjustable, said left and right side frames ( 3,3 ) can be connected by said X-frames(s) ( 11 ) to correspond to the change of the height of said X-frame(s) ( 11 ).
