Abstract
A cylinder-like electromagnetic motor of the present invention is disclosed. When a current is supplied to the electromagnetic element to produce an electromagnetic field, the magnet element and the electromagnetic element mutually repulse or attract to produce a push force against the holder to move the holder forward. When the current is cut off, the electromagnetic field vanishes and the spring piece elastically pushes the holder backward to an initial position in the base.
