PROBLEM TO BE SOLVED: To enable a bed sheet to be securely supported to prevent a build-up of storm water, snow, etc., to be easily and quickly attached/detached to a bed, and to be loaded compactly in the corner of the bed when detached. SOLUTION: A supporting lever 1A is equipped with a long narrow bar lever body 2, a first hook 3 formed on one end of the lever body 2, a second hook 4 formed on the other end of the lever body 2, and length-adjusting mechanism 6, 7 to regulate length. Substantially at the center in a cross direction on the top face of the bed, the supporting lever 1A is laid between a ledge 23a of a frame 23 at the bed front end, and a rear frame wall 21a at the bed rear end, such that the supporting lever is inclined upward toward the front. By covering a sheet on the supporting lever, the sheet is supported in a condition where it is inclined upward toward front with its center portion rising like a spine.
