Beschreibung
Zusammenfassung:	This abstract replaces all prior versions of abstract in the application. The linear vibration motor comprises a movable element that is equipped with a magnet portion and a weight portion; a frame that contains the movable element; a coil that is secured to the frame and that drives the magnet portion along an axial direction; an elastic member that is disposed within the frame and that applies, to the movable element, an elastic force that repels the driving force that is applied by the magnet portion; and a guide shaft 8 that is borne on the frame and that guides reciprocating motion of the movable element along the axial direction, wherein: the elastic member rotationally biases the movable element in one direction around the guide shaft 8, and the frame comprises a slide bearing portion (a slide plate) for bearing slidably a portion of the rotationally biased movable element.
