To provide a compressor where an oil supply hole communicating with an oil supply mechanism in a shaft-hollow part and that improves reliability and performance by supplying oil to upper and lower sliding parts through different channels.

A lubricant 103 is supplied to the upper sliding part 184 and the lower sliding part 188 from the oil supply hole 190 provided in the hollowed part 186. Accordingly, a time until the lubricant 103 is supplied to each sliding part from at the start can be shortened and reliability is improved. Moreover, since independent fuel inlet grooves 192, 194 can be provided in the upper and lower sliding parts 184, 188, the fuel inlet grooves 192, 194 can be arranged by aiming at a portion having a smaller load at operation. Accordingly, a sliding loss can be reduced.
