1. A compressor for an automobile air conditioning device comprising:
a compressor body;
a pipe connected to a flange portion that protrudes from an outer surface of the compressor body;
a connection block fixed around the pipe and fastened to the flange portion; and
an acoustic cover disposed around the compressor body,
wherein the acoustic cover has an insertion hole through which the pipe is inserted, and which is indirectly brought into close contact with the pipe, and an inner surface of the acoustic cover has a shape that follows the outer surface of the compressor body, the outer surface of the compressor body and the inner surface of the acoustic cover defining a gap therebetween, and
the insertion hole comes into contact with the flange portion, the connection block, and the outer surface of the compressor body, and
the acoustic cover has an annular inclined portion that extends toward the compressor body around the insertion hole as the acoustic cover extends toward the insertion hole, and
wherein the acoustic cover is a porous foam material.
