PROBLEM TO BE SOLVED: To simplify the structure of a vibration compressor for making it compact and improvement of the accuracy of assembling. SOLUTION: A yoke for transmitting magnetic flux of a permanent magnet 13 forming a linear drive unit 9 with a vibrator coil 11, and a cylinder and a pressure container body 26 are integrally formed with each other as a body block 28. A piston 3, which is to be inserted into the cylinder 1, is supported in a cantilever manner by two pairs of support springs 7 and 8 at an end opposite to an operating gas compression space 5, and the linear drive part 9 is arranged in parallel, in the radial direction of the piston. As compared to the structure of the linear drive part 9 being arranged in series in the axial direction of the piston, the longitudinal dimension of the piston part is reduced, and since a plurality of parts are arranged collectively in the body block 28, the number of parts items is reduced to improve the assembling accuracy.
