PROBLEM TO BE SOLVED: To install a brush for massage with a brush for scraping stains out, and to allow motions respectively appropriate to each brush.SOLUTION: A high-speed shaft with a high rotation rate, a low-speed shaft with a low rotation rate and a motor M are provided in a gear case. While each shaft is linked to the motor through a gear, a plurality of swivel rods are raised on one side of the gear case, and base ends of the swivel rods are fixed on each shaft in a condition to be inclined to rotation axes of the high-speed shaft and the low-speed shaft. In addition, a flexible brush board integrally formed with a plurality of arranged hollow columnar brushes is put over one side of the gear case. The gear case is sealed by passing the swivel rods through each hollow part of the columnar brushes.COPYRIGHT: (C)2011,JPO&INPIT【課題】揉み用のブラシと汚れ掻き出し用のブラシを併設すると共に、各ブラシをそれぞれに適した動きにする。【解決手段】ギアケース内に回転速度の速い高速軸と遅い低速軸及びモータMを設け、各軸とモータとをギアを介して連結する一方、ギアケースの一側面には複数本の旋回ロッドを起立し、これら旋回ロッドの基端を前記高速軸及び低速軸の回転中心に対し傾斜した状態で各軸に固定し、そして内部が中空の柱状ブラシを複数本並べて一体的に成形した柔軟な材質のブラシ板を前記ギアケースの一側面に被せ、これら柱状ブラシの各中空部に旋回ロッドを挿通することによりギアケースをシールする。【選択図】図3
