<P>PROBLEM TO BE SOLVED: To provide a thrust bearing structure and a supercharger in which, even if a rotation direction of a rotary shaft is different, increase in the number of part items and in the number of assembly man-hours can be suppressed. <P>SOLUTION: A thrust bearing structure 5 includes: a thrust collar 51 which is held by a rotary shaft 3 and rotated together with the rotary shaft 3; and a pair of thrust bearings (compressor-side thrust bearing 52 and turbine-side thrust bearing 53) disposed at both sides in an axial direction of the rotary shaft 3 of the thrust collar 51. On a pressure receiving surface 51a confronted with the thrust bearings 52, 53 of the thrust collar 51, a plurality of tapered surfaces 511 tilted with respect to a plane defining the rotary shaft 3 as a perpendicular and land surfaces 512 continued to the tapered surface 511 and parallel to the plane defining the rotary shaft 3 as the perpendicular are disposed alternately in a circumferential direction of the rotary shaft 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
