Abstract
An object of the present invention is to provide a linear motor and a compressor which are effective against a non-fixed structure in which end portions of a resonant spring are not fixed and are capable of restraining loads in an up-down direction and a left-right direction which act on a slider. A linear motor includes a slider () which is driven in a first direction, a resonance spring () which is capable of vibrating in the first direction, and a permanent magnet () which is provided at the slider () and is magnetized in a second direction perpendicular to the first direction. The linear motor includes a bearing () that is movable against both forces of a force in the second direction and a force in a third direction perpendicular to the first direction and the second direction, and an elastic-body support member () which connects the resonant spring () and the bearing () to each other.
