Claims

[Scope of utility model registration request]

A box having a profile slightly smaller than the area of the lid is provided on the lower surface of the lid with a tatami mat fixed to the upper surface, and the lid is supported so that it can be opened with one side end facing upward. A pair of movable brackets protruding into the inside of the box are provided on both sides of the opening/closing base end of the lid body, and a pair of movable brackets protruding from the opening/closing base end of the lid body toward the open end side are provided on the opposite side walls of the box body. A second fixed bracket of the first fixed bracket corresponding to the movable bracket is attached to the movable bracket, and two long and short upper and lower links are arranged and connected in parallel between the movable bracket and the first fixed bracket. A telescopic gas cylinder is connected between the movable bracket and the second fixed bracket, and the two links and one gas cylinder work together to connect the pivots on the first and second fixed bracket sides. This opening/closing device for an under-tatami storage is characterized in that a cover body is supported diagonally upward along with a tatami mat so as to be openable and closable, using a fitting part as a fixed fulcrum and a pivoting part on a movable bracket side as a movable fulcrum.
