    • A shock absorber (10) includes a damper case (15) provided to hold an outer tube (21) and an inner tube (20) such that an upper end of the outer tube (21t) is positioned closer to a side on which a piston rod (13) is disposed than an upper end (20t) of the inner tube (20). The damper case (15) includes a damper housing portion (29) that houses a damper unit (41), a compression-side communication path (102) through which an inner side of the inner tube (20) and the damper housing portion (29) communicate with each other, an extension-side communication path (105) through which an annular passage (101) and the damper housing portion (29) communicate with each other, and a passage opening (104) which is formed on the opposite side to the piston rod (13) of the outer tube (21). The extension-side communication path (105) and the annular passage (101) communicate with each other through the passage opening (104).
    • 本发明的冲击吸收装置(10)具备:为了保持外管(21)和内管(20)而设置的阻尼器壳体(15),以使外管(21t)的上端位于靠近 活塞杆(13)设置成比内管(20)的上端(20t)更远。 该减震器壳体15具有:收纳减震器单元41的减震器收纳部29;压缩侧连通路102,该内侧管20的内侧和减震器收纳部 29)彼此连通;环形通道(101)和阻尼器容纳部分(29)通过其相互连通的延伸侧连通路径(105);以及形成在相对侧的通路开口(104) 侧面与外管(21)的活塞杆(13)连接。 伸长侧连通路径105和环状通路101经由通路开口104连通。
