Claims

[Scope of utility model registration request]

A permanent magnet and a pole piece that forms an annular gap between the permanent magnet and the permanent magnet are fixedly disposed in a casing consisting of a cylindrical yoke with one end closed and the other end closed with a closing member. A drive coil energized by alternating power is disposed in the gap so as to be movable in the axial direction of the casing, and a piston that is substantially integral with the coil is slid into a cylinder portion provided in the closing member. In the vibratory compressor, the yoke includes a mounting groove bored all around the inner surface of the other end of the yoke, a protrusion forming a side surface of the mounting groove on the other end of the yoke, and A ring-shaped disk made of an elastic material that is attached to the mounting groove and has a plurality of screw holes is formed in the form of a cutout, and positioning holes are provided at respective positions close to both ends in the circumferential direction. and an arcuate mounting plate having an arc-shaped mounting plate, and the closing member is configured to be fixed to the other end of the yoke by a screw member that passes through the closing member and is screwed into a screw hole of the mounting plate, The mounting plate is caulked by the protrusion in a state in which the distance between the positioning holes is expanded and the entire outer peripheral surface of the mounting plate is brought into close contact with the bottom surface of the mounting groove. Vibratory compressor.
