PROBLEM TO BE SOLVED: To obtain a rotatable and displaceable side guard for bed which has no projection for operation and can be safely and reliably operated.SOLUTION: A fixing guard frame 11 and a movable guard frame 12 are rotatably connected by a connection structure 13. The connection structure 13 are provided such that a fixing side connection cylindrical body 16, a movable side connection cylindrical body 18, and a joint cylindrical body 25 are outwardly fitted to a vertical axis 14 around the vertical axis 14. Also, the joint cylindrical body 25 is covered with a cylindrical grip 30, and a stopper structure 31 for preventing the grip 30 from carelessly moving to an axial direction is provided. Thereby, the connection structure has no projection for operation, and it is possible to safely operate the connection structure only when needed and rotate the movable guard frame 12.
