き、使い勝手が良好となる。As described above, according to the first aspect of the present invention, the lid for opening and closing the opening of the storage main body is rotatably connected to the frame of the storage main body via the hinge. In the underfloor storage, the lid is automatically opened in a direction to open from a closed position at a predetermined angle from the fully opened state in which the lid is upright, and in a direction to close from a position opened by a predetermined angle than the fully closed state with the lid down. Lid opening and closing means for automatically closing the lid,
Braking means for applying a predetermined braking force to the lid opening / closing means, wherein the lid opening / closing means has a first link member pivotally supported at one end by a support fitting attached to the storage main body;
A second link member one end of which is pivotally supported by the other end of the first link member and the other end of which is pivotally supported at a position above the hinge portion of the lid; a substantially central portion of the first link member; And a tension spring that is biased in a direction to always open the first link member in a direction to open the first link member. The spring force of the tension spring and the braking force of the braking unit are equal to or greater than a predetermined angle. At this time, the tension spring automatically opens the lid gently against the braking force of the braking means, and when the lid is at a predetermined angle or less, the lid is closed against the spring force of the tension spring and the braking force of the braking means. Because it is set to close automatically by its own weight,
The lid can be automatically opened and closed from a predetermined angular position by the lid opening / closing means, respectively, so that the burden on the user can be reduced, and when the lid is fully opened with the lid upright, the fall of the lid is prevented by the spring force of the tension spring. Therefore, there is no fear of the cover accidentally falling, and safety is ensured. Moreover, by applying a constant braking force to the lid opening / closing means by the braking means, the speeds of the automatic opening and the automatic closing of the lid become slower, respectively. Since it does not open well and does not vigorously close when closing the lid, it is possible to prevent the lid and the frame from colliding with each other and to generate a loud noise, thereby improving usability.
