ABSTRACT:
An automatially tiltable small roller structure of slide bearing type for video tape recorders which has a small roller (10) including an elastic rubber cylinder (11) and a sleeve (12) integral with the inner periphery of the cylinder, the sleeve having a lower inside diameter surface (13) and an upper inside diameter surface (14) with a smaller diameter the former to form a stepped portion (15) inside the sleeve (12), an outer race (21) fitted to the stepped portion, a row of bearing balls (23) fitted in the outer race and located at a middle point between the opposite ends of the sleeve, a shaft (30) having a lower shaft portion (31), an upper shaft portion (32) having a smaller diameter than the lower shaft portion and a tapered surface portion (33) extending between the two shaft portions, the bearing balls being provided such that they are brought into rolling contact with the tapered surface, a region of the upper shaft portion adjacent thereto and the inner peripheral surface of the outer race and first and second plastic sleeves (34), (35) pressed onto the opposite end portion of the shaft, respectively and having a small coefficient of friction and a small coefficient of wear. The second sleeve (35) has at an outer end thereof a flange (36) having a larger diameter than the upper inside diameter surface (14). The roller structure also has a lower annular clearance between the first plastic sleeve (34) and the lower inside diameter surface (13) and an upper annular clearance between the second plastic sleeve (35) and the upper inside diameter surface (14).
