A support structure carrying a thrust load of a compressor has a swash plate which contributes to a compressing operation by rotating according to rotation of a rotating shaft which is rotatably supported by a housing. The swash plate is rotatably supported with respect to the housing, and the support structure includes a thrust needle roller bearing having double-row needle rollers. The support structure carrying a thrust load of a compressor and the thrust needle roller bearing are thus obtained, with an improvement in inflow and outflow of a lubricating oil, a reduction of the differential slip of the needle rollers, and an improvement in strength durability.
