PROBLEM TO BE SOLVED: To provide a damping structure capable of reducing vibration transmitted to a frame from an excitation source such as a motor.SOLUTION: Vibrational energy for vibrating a driving frame 101 is converted into heat energy by distorting a damping material 112 compressed and held between the driving frame 101 and a pin member 114. As a constitution for the same, a damping pin 110 for compressing and holding the damping material 112 and transmitting vibration of the driving frame 101 to a face at a side opposite to a face kept into contact with the driving frame 101, of the damping material 112, is disposed between the driving frame 101 and a main frame 102. Thus, the vibration of the driving frame 101 is efficiently transmitted to both faces at a front side and a back side of the damping material 112, and the damping material 112 is easily distorted. By disposing the damping pin 110, the vibration is efficiently reduced, and radiation noise caused by vibration can be remarkably reduced.SELECTED DRAWING: Figure 3 【課題】モータなどの加振源からフレームに伝達される振動を低減可能な制振構造体の提供。【解決手段】駆動フレーム１０１とピン部材１１４との間に圧縮保持した制振材１１２を歪ませて、駆動フレーム１０１を振動させる振動エネルギーを熱エネルギーに変換させる。そのための構成として、制振材１１２を圧縮して保持すると共に、制振材１１２の駆動フレーム１０１に接する面と反対側の面に駆動フレーム１０１の振動を伝える制振ピン１１０を、駆動フレーム１０１とメインフレーム１０２との間に設けた。こうすると、駆動フレーム１０１の振動が制振材１１２の表面側と裏面側の両面に効率的に伝えられ、制振材１１２に歪みが生じやすくなる。このように、制振ピン１１０を設けたことで、振動を効率よく低減して振動起因の放射音を大幅に低減することができる。【選択図】図３
