[Action]

 In the present invention, a supporting piece 3 having a long groove 2 is provided on one side surface of the frame 1 fixed to the upper portion of the snow drift groove M in a substantially horizontal manner, while a rim 4 of the upper portion of the frame 1 is provided. In the lid body 5 to be covered, a pivot support piece 6 having a rectangular cross section is horizontally fixed to a side portion 5a corresponding to the support piece 3, and a pivot support hole 8 provided in advance at an upper end of the connecting movable rod 7 is provided. A tongue-shaped engaging end portion 9 that is rotatably connected to the pivotal support piece 6 and protrudes from the lower end of the connecting movable rod 7 is allowed to pass into the long groove 2, and the engaging end portion 9 is formed in the long groove 2. On the other hand, the locking groove 10 for engaging the pivot piece 6 is provided in the pivot hole 8 at a phase of approximately 90 degrees, and the operation of the present invention is as follows. That is, as shown in FIG. 1, when the left side of the lid 5 shown in the figure is lifted to rotate the lid 5 closed to release the closed lid 5, the pivotal support piece 6 of the lid 5 is connected. Movable rod 7 Since the pivot piece 6 is engaged in the locking groove 10 above the pivot hole 8 while rotating in the pivot hole 8 at the upper end of the movable rod 7, together with the connecting movable rod 7, When the lid body 5 is tilted integrally, and the lid body 5 is tilted slightly from the vertical state to the right side in the drawing as shown in FIG. 2, the released state of the lid body 5 is maintained. This is because the connecting movable rod 7 is locked by the left inner edge 2a of the long groove 2 of the support piece 3 in the figure. When the lid 5 in the half-open state is to be fully opened horizontally to the right as shown in FIG. 4, when the connecting movable rod 7 is pulled upward, the pivot support piece 6 becomes rotatable with the pivot support hole 8. The lid 5 can be fully opened horizontally as shown. Further, even if the lid body 5 in this state is rotated leftward in the figure by an unexpected external force, the lower end portion 9 of the connecting movable rod 7 is engaged with the inner right side surface 1a of the frame body 1 in the figure as shown in FIG. Since it is stopped, the tilted state is maintained while the lid 5 is slightly tilted to the left in the drawing. Next, when the frame body 1 is completely covered with the lid body 5, first, the lid body 5 is held while the connecting movable rod 7 is pulled upward, and the pivot support piece 6 and the pivot support hole are formed. Since 8 can be rotated again, the frame body 1 can be completely covered with the lid body 5 as shown in FIG.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. In this example, a supporting piece 3 having a long groove 2 is substantially horizontal on one side surface of a frame body 1 fixed to an upper portion of a snow drift groove M. On the other hand, the lid 5 for covering the rim 4 on the upper part of the frame 1 is provided with a pivotal support piece 6 having a rectangular cross section with respect to the side portion 5a corresponding to the support piece 3 in a horizontal manner. A pivot hole 8 which is fixed and is previously provided at the upper end of the connecting movable rod 7 is rotatably connected to the pivot piece 6, and a tongue-shaped engaging end portion 9 protruding at the lower end of the connecting movable rod 7 is provided in the long groove 2. By allowing the engaging end portion 9 to be phased with the long groove 2 at an angle of approximately 90 degrees, a retracting groove 10 for retracting the pivotally supporting piece 6 is provided in the pivoting hole 8. is there. In addition, 1a is a right inner side surface of the lid 1, 2a is a left inner edge of the long groove 2 of the support piece 3, and 7a is a finger hook portion at an upper end of the connecting movable rod 7, which can pull up the rod 7. .. The operation of this embodiment is as described above.

[0007]

[Effect of device]

 This invention has as its gist the construction described in the section of the utility model registration claim, and the above-mentioned operation is performed by the unique construction (a) When the lid 5 is opened as shown in FIG. The lid 5 is a kind of warning plate that has the effect of warning the third party of the open state of the snowdrift basin M, and (b) the lid 5 opened due to an unexpected accident is closed in the closing direction (shown in the figure). Even if the lid 5 is rotated, the lid 5 is stopped in the state shown in FIG. 3, so that there is a remarkable effect that the danger of being completely closed can be prevented from rotating to the left.
