Summary:PROBLEM TO BE SOLVED: To provide a damper that can either increase a regeneration efficiency or further preferably control damping force at least, and to provide a method for controlling a damper.SOLUTION: A control device 36 for the damper 22 controls a switching element 80 using a duty factor where an electromagnetic motor 66 exerts the best regeneration efficiency or duty ratio where the regeneration efficiency is a variable value or fixed value that exceeds a prescribed efficiency threshold when a prescribed frequency input vibration is input to a damper body 30 from an unsprung member.SELECTED DRAWING: Figure 1 【課題】回生効率を向上すること及び減衰力の制御をより好適に行うことの少なくとも一方が可能なダンパ及びダンパの制御方法を提供する。【解決手段】ダンパ２２の制御装置３６は、所定周波数の入力振動がばね下部材からダンパ本体３０に入力されたときにおける電磁モータ６６による回生効率が最大となるデューティ比又は回生効率が所定の効率閾値を上回る可変値又は固定値であるデューティ比を用いてスイッチング素子８０を制御する。【選択図】図１
