<；P>；PROBLEM TO BE SOLVED: To provide a pet tray holding a sheet in such a state wherein the sheet is always extended over the pet tray while preventing occurrence of breakage etc., of the sheet caused by scratching etc., with a pet as much as possible. <；P>；SOLUTION: The sheet 3 extended over a top surface 22 of the tray is held with clipping means 41. Furthermore, each clipping means is connected through a connecting string 43 to a reel means 42. A housing recessed part 23 for the clipping means is formed in a bank part 21 on the periphery of the top surface of the tray, and a recessed receiving part 24 is formed in the base of the housing recessed part. The shift of the sheet is permitted by winding and urging the connecting string with a spiral spring 421 of the reel means, and drawing out the clipping means onto the top surface of the tray by receiving scratching force. Meanwhile, if the scratching force is eliminated, the clipping means is brought back by winding and urging force, and automatically returned to a reference position where a fitting part 414 is internally fitted into a receiving part, touched and stopped. <；P>；COPYRIGHT: (C)2010,JPO&INPIT
