A bracket (20) that is fixed to a band (10) mounted on an outer peripheral surface (2a) of a cylinder tube (2) supports a pipe (4). The band (10) includes a first tab (11a) projecting outward in a radial direction and a second tab (11b) projecting outward in the radial direction. The bracket (20) supporting the pipe (4) is formed with an inverted U-shaped cross-section constituted by a pair of leg plate portions (20a) and a top plate portion (20b) formed integrally with the leg plate portions (20a) to join the leg plate portions (20a). The pair of leg plate portions (20a) are fixed to the first tab (11a) and the second tab (11b) by a bolt, and a small and lightweight pipe fixing structure is thus realized.
