Abstract: A rotary amusement device for supporting a child and enabling him to propel himself in a circular path about a vertical axis. The device includes a seat member which is rotatably supported on a base member for rotation about an upstanding vertical post member. A first ratchet gear is non-rotatably attached to the post member. A hollow sleeve member is positioned completely around the post member and houses a second ratchet gear in a slideable non-rotational manner to thereby facilitate ratchetable engagement with the first ratchet gear. A grippable handle member is attached to the sleeve member for effectuating a ratcheting motion of the sleeve member around the upstanding post member.
