<p>A coupling bar (10,47) couples upper ends of a pair of upwardly extending upright bars (3,4,45) with each other, to define a prescribed space between the pair of upright bars (3,4,45). Base members (5,6,46) are provided on lower end portions of the upright bars (3,4,45) respectively, while plural wheels (8,9,43) are mounted on the base members (5,6,46) to roll on a floor face (7,51). A support member (11,48) for supporting a human body is mounted to be movable along the upright bars (3,4,45) and stoppable at a moved position. The support member (11,48) comprises two parallel side bars (12,13) extending across the pair of upright bars (3,4,45) respectively. <IMAGE></p> |
