PROBLEM TO BE SOLVED: To strongly fix a tube of a cylinder body and a guide member for supporting a protective cover.SOLUTION: On an outer peripheral surface 37H of a tube 37 of an angle cylinder 36, a guide member 42 for movably guiding a protective cover 41 is provided. The guide member 42 includes a protective cover guide part 43 and a tube fixation part 44, and the tube fixation part 44 is provided with an opposed surface 45 which has a circular arcuate surface and faces the tube 37. When welding the tube fixation part 44 to the outer peripheral surface 37H of the tube 37, by bringing the tube fixation part 44 into contact with the outer peripheral surface 37H of the tube 37 at a plurality of contact positions of the outer peripheral surface of the tube separated in a circumferential direction, the guide member 42 can be abutted stably on the outer peripheral surface 37H of the tube 37 and the guide member 42 can be strongly fixed to the outer peripheral surface 37H of the tube 37. |
