PROBLEM TO BE SOLVED: To provide an apparatus for loading vibration capable of changing a mechanical behavior inside a biological body.SOLUTION: An apparatus for loading vibration of an embodiment includes: a contact unit provided so as to be in contact with a living body which pulsates or beats in a contact state of a first contact condition； a first vibration unit for giving self-excited vibrations to the living body through the contact unit； a storage unit for storing a second contact condition for synchronizing the pulsation or beat with the self-excited vibrations； and a control unit for controlling the contact state of the contact unit in a direction bringing the first contact condition closer to the second contact condition.【課題】生体内の力学的な挙動を変化させることが可能な振動負荷装置を提供する。【解決手段】実施形態の振動負荷装置は、脈動または拍動する生体に対して、第１接触条件の接触状態で接触可能に設けられる接触部と、前記接触部を介して前記生体に対して自励振動を与える第１振動部と、前記脈動または拍動と前記自励振動とを同期させる第２接触条件を記憶する記憶部と、前記第１接触条件を前記第２接触条件に近づける方向に前記接触部の前記接触状態を制御する制御部とを備える。【選択図】図１
