Claim Text:
1. A vibration reducing apparatus having a vibration damping unit which comprises: a dynamic mass; an elastic member configured to apply elastic force to said dynamic mass such that said dynamic mass vibrates in parallel to a vibration damping direction to a vibration damping object; a control mass; an actuator coupled to said dynamic mass at a first position of said dynamic mass, to drive said control mass by elongating and contracting in an operation direction of said actuator as a direction of elongation or contraction of said actuator; and a motion direction converting mechanism configured to couple said control mass to said dynamic mass at a second position of said dynamic mass which is different from the first position and to move said control mass to said dynamic mass into the vibration damping direction through elongation and contraction of said actuator, wherein said actuator is supported by said dynamic mass such that the operation direction of said actuator is not parallel to the vibration damping direction.
