PURPOSE:To realize the tilting actions utilizing the oscillating motions and to attain the easy handling and easy production by securing a contact between a 1st oscillating foot and a 1st oscillating surface and setting a 1st inserting wall into a 1st groove. CONSTITUTION:When an oscillator 401 is set on a base 402, a sleeve 450 covers a sleeve 424 together with tabs 404 and 445 fitted into tab grooves 409 and 448 respectively. An oscillating foot 437 has a contact with an oscillating surface 446 with an oscillating foot 444 having a contact with an oscillating surface 447. A gear foot 405 is meshed with a gear 410 and a gear foot 443 is meshed with a gear 416 respectively. The inserting walls 438-442 are put into grooves 411-415 respectively. The friction springs 435 and 436 give the spare load to the groove walls 425-434 and apply the frictional compression force to the insides of the grooves 412 and 414. The foot 405 is bent to a rack gear 410. Thus the sure oscillating motions are secured with no sliding action. |
