To provide a transformer in which an iron core and windings that reduce vibration of an enclosure are housed in the enclosure.SOLUTION: A transformer 1 includes an enclosure 4 that houses an iron core 2 and winding 3, and a vibration reduction mechanism 10 that reduces the vibration of the enclosure. The vibration reduction mechanism 10 includes a coupling member 11 fixed outside the enclosure 4 and vibrating in the same direction as the vibration of the enclosure 4, and a friction member 12 sliding with the coupling member 11 when the coupling member 11 vibrates. The vibration of the enclosure 4 is suppressed by frictional damping caused by sliding between the coupling member 11 and the friction member 12.SELECTED DRAWING: Figure 1 【課題】筺体の振動を低減する鉄心及び巻線が筐体に収容される変圧器を提供する。【解決手段】鉄心２及び巻線３を収容する筐体４と、筐体の振動を低減する振動低減機構１０と、を備えた変圧器１であって、振動低減機構１０は、筐体４の外部に固定されて筐体４の振動と同方向に振動する連結部材１１と、連結部材１１の振動にて連結部材１１と摺動する摩擦部材１２と、を備えている。連結部材１１と摩擦部材１２との摺動による摩擦減衰によって筐体４の振動を抑制している。【選択図】図１
