PROBLEM TO BE SOLVED: To provide a storage type top plate in which a top plate is prevented from falling suddenly by simple constitution. SOLUTION: The storage type top plate is provided with a roller part 3 which is provided in a storage part 2 to be in contact with the top plate 1 and is rotated by slide moving of the top plate 1 with respect to the storage part 2, and a unidirectional rotary damper 4 connected with the roller part 3 for generating resistance force to the rotation of the roller part 3 caused by moving the top plate 1 in a storing direction.
