Abstract
A vibration type compressor related to the present invention, in which a compressor main body 3 is built into a gastight vessel 2 including a yoke 7-1, a magnetic path member 7 formed from a column-shaped core pole 7-2, a permanent magnet 12 arranged in the magnetic path, an electromagnetic coil 14 which is arranged within an annular magnetic gap 13 between the magnetic path members 7 by being supported by a mechanical vibration system to as to be able to vibrate and is wound around a lead plate to perform the connection treatment of a terminal thereof, a piston 16 connected to the electromagnetic coil 14, and a cylinder block 8 which closes the yoke 7-1 and in the interior of which is formed the cylinder portion 17 housing the piston 16, characterized in that the permanent magnet 12 is formed from a neodymium magnet or a rare-earth magnet and in that the cylindrical permanent magnet 12 is divided into four parts in the axial direction thereof, the four-part divided magnet being bonded and fixed to the side of the core pole 7-2, whereby the vibration type compressor is miniaturized and its efficiency is increased.
