<p>A vibrator for therapy is disclosed which can apply fine vibration of high frequency to a human body for medical treatment of such physical disorder as bruise. The vibrator includes a base frame (10) with top and underside surfaces, a vibratory head (12) mounted on the top surface of the base frame for reciprocating movement across the base frame, and a spindle (28) rotatably fitted through the base frame (10) in a perpendicular relationship with respect to the vibrator head (12), the spindle having an eccentric cam shaft (34) protruding toward the vibratory head (12). An electric motor (38) is attached to the underside surface of the base frame (10) for rotatingly driving the spindle (28) so that the eccentric cam shaft (34) can be subjected to turning movement about a longitudinal axis of the spindle. Provided between the base frame (10) and the vibratory head (12) is a motion converter (44) capable of converting the turning movement of the eccentric cam shaft (34) into the reciprocating movement of the vibratory head (12).</p> |
