Zusammenfassung:	To provide a method for manufacturing a damper that can reduce a shaft length of a junction part between a piston rod and a piston mechanism.SOLUTION: A method for manufacturing a damper includes the steps of: providing a nickel-based amorphous alloy 37 to a connection part 21 between a piston rod 3 and a piston mechanism 11; and joining the piston rod 3 to the piston mechanism 11 at the connection part 21 with pulse energization while compressing them in an axial direction, thereby joining the piston rod 3 to the piston mechanism 11. Thus, the method can reduce a shaft length of the connection part 21 as compared to existing manufacturing methods using a screw.SELECTED DRAWING: Figure 4 【課題】ピストンロッドとピストン機構との接合部の軸長を短くすることが可能な緩衝器の製造方法を提供する。【解決手段】ピストンロッド３とピストン機構１１との結合部２１にニッケル系アモルファス合金３７を設ける工程と、ピストンロッド３とピストン機構１１とを軸方向へ加圧した状態で結合部２１をパルス通電接合させる工程と、を含む製造方法により、ピストンロッド３とピストン機構１１とを接合させる。これにより、ねじを用いた従来の製造方法と比較して、結合部２１の軸長を短くすることができる。【選択図】図４
