Abstract: A foot massage device capable of augmenting or restoring function of the transverse metatarsal ligament and alleviating foot pain felt by a user has increased massage effect on a user foot and is configured to be capable of imparting various stimuli to the user foot. A foot massage device includes: a cover body; a footrest including a footrest plate, a left/right rotary shaft, and a front/rear rotary shaft; an air bag including an inner instep air bag, a sole air bag, an outer instep air bag, and an ankle air bag; an air supply/exhaust device; a front/rear oscillation drive mechanism; and a base. The footrest plate oscillates left and right about the left/right rotary shaft in response to expansion and contraction of the air bag, and oscillates forward and backward about the front/rear rotary shaft in response to driving of the front/rear oscillation drive mechanism.

Abstract: The portable massaging apparatus has a pair of driving shafts, 11 and 12, each of which is placed opposite and slant each other so that the distance between center axes of the driving shafts increases along with the distance from the root position to the top position of each driving shaft. A pair of slant shafts, 5 and 6, are extended from the top position of the each driving shaft keeping each angle between the center axis of the slant shaft and the center axis of the driving shaft to an approximately same constant value. A pair of massaging balls, 3 and 4, are attached to the tops of the slant shafts so that each massaging ball rotates freely around the center axis of each slant shaft. A driving mechanism rotates the pair of driving shafts at the same speed in the opposite direction so that each of the slant shafts moves synchronously and mirror symmetrically each other.
