Abstract
A compressor of an embodiment includes: a piston that is housed in a case and moves back and forth in an axis direction inside the case; a main shaft that i) extends in the axis direction inside the case, and ii) guides the piston to move in the axis direction; and a drive that drives the piston to move along the axis direction. The piston includes: a main shaft bush through which the main shaft passes in the axis direction; and a compression board that has an outer diameter greater than an outer diameter of the main shaft bush, and that is fixed to an end portion of the main shaft bush on a side in the axis direction. Fluid inside the case is compressed, and then is ejected to an outside of the case. The drive is arranged between the compression board and an end portion of the case.
