The present invention is to solve a problem of a lifting device for a conventional wheelchair, and is to provide a lifting device for a wheelchair with a rotatable riding portion capable of safely rotating without rolling or pitching while having an infinite rotation angle while guiding each other with respect to a rotation support plate installed at the lower portion thereof for the rotation plate installed on the bottom of the riding portion to precisely rotate. The lifting device for a wheelchair with a rotatable riding portion according to the present invention includes a rotation plate which is installed on the bottom of the riding portion, and a rotation support plate which is installed at the lower portion of the rotation plate. The riding portion is stopped at an arbitrary position by rotation of the rotation plate. A support bearing is installed at the center of the rotation support plate, multiple plane guide blocks and side guide blocks are installed along the circumferential direction at a distance separated to the outside with respect to the support bearing, a rotation shaft is installed to rotate with respect to the support bearing at the center of the bottom of the rotation plate positioned at the upper portion of the rotation support plate, and a ring-shaped guide block is installed to come in contact with the plane guide block and the side guide block. |
