To effectively cool an operation part, in a linear vibrating compressor for sucking and delivering outside air with every vibration of each time, by linear vibrating a driving shaft having a piston fitted in a cylinder in an end part.

This linear vibrating compressor compresses gas sucked in the cylinder in response to reciprocating motion of this piston, by fitting the piston installed in the end part of the electromagnetically linear vibrating driving shaft 12 in the cylinder. A cooling projection is projected around the driving shaft 12.
