Structure is provided whereby the lower leg of a horizontally disposed generally U-shaped leaf spring of a "hobby-horse" is oscillatably supported from its supportive base as opposed to rigidly secured thereto, but with oscillation of the leaf spring of the base limited to a relatively short arc of angular displacement. In addition, the lower leg of the U-shaped leaf spring includes structure whereby the axis of oscillation of the leaf spring relative to the base may be adjusted longitudinally of the lower leg and the base is equipped with spring-type abutment structure for limiting angular displacement of the lower leg of the spring relative to the base in at least one direction.
