A tiltable roller assembly includes a roller, a sleeve tightly fitted into the roller, a supporting shaft extending through the sleeve, the supporting shaft having a small diameter section and a large diameter section, a rotating member for pivotally carrying the roller and the sleeve about the supporting shaft and a cushion member for allowing the roller and the sleeve to tilt with respect to the supporting shaft. The rotating member has at its periphery an external groove for accommodating the cushion member and a bore through its center and a protruding portion, inwardly extending from an upper end of the bore, for serving to limit the amount of the descent of the rotating member. |
