PURPOSE:To obtain an oscillating implement for sliding smoothly a slide plate by providing two pieces of slide shafts so as to be positioned horizontally right under a foot placing base in the vicinity of the ceiling surface of a main body case, and forming a connecting projecting line on the center line of the slide plate. CONSTITUTION:A driving mechanism 4 consists of a pair of slide shafts 5, 5 provided in parallel to the reciprocating motion direction of a foot placing base 2 and a slide plate 6, a driving motor 3, and a reduction gear 31 attached to the driving motor 3, and to the output shaft of the speed reducer 31, a crank arm 32 is attached and a pulley 33 is fitted loosely thereto. Two pieces of slide shafts 5, 5 are provided horizontally in a position being right under the foot placing base 2 in the vicinity of the ceiling surface of a main body case 1. To the slide shafts 5, 5, the slide plate 6 is attached so as to be freely slidable. Since the slide plate 6 and the foot placing base 2 are adjacent to each other, a twist tendency is scarcely generated between the slide shafts 5, 5 and the slide plate 6, and the slide plate 6 executes a reciprocating motion smoothly along the slide shafts 5, 5. |
