A position regulating tool for returning the portion to the reference position is provided between the lid plate and the frame.

In the present invention, both of the position restricting members comprise a contact portion between a spring supported by the frame body and the lid plate, and at the reference position, the spring contacts the contact portion on both the left and right sides while the lid is in contact with the contact portion. When the plate is held and the left portion of the lid plate is pushed downward from the reference position, the contact portion of the lid plate abuts on the spring at the left portion, and the downward rotation of the left portion of the lid plate is elastically performed. A position restricting tool having a spring that allows the downward rotation of the cover plate to a predetermined range while receiving the same, and that returns the left portion of the cover plate to the reference position when the pressing force is removed, and a right portion of the cover plate. When pushed downward from the reference position, the contact portion of the lid plate abuts on the spring at the right portion, elastically receiving the downward rotation of the right portion of the lid plate and allowing the downward rotation to a predetermined range. When the pushing force is removed, the right side of the lid plate is When the configuration in which a position restricting mechanism having a spring for restoring moving to a position, which is preferable.

Further, in the present invention, both of the position restricting members are constituted by a spring provided on the cover plate side and a contact portion provided on the frame body side.

According to the present invention, the cover plate is pivotally supported by the frame so as to be rotatable around a center line that divides the cover plate into two right and left parts. The body opening is closed. When discarding dust and the like into the swinging pawl, pushing one of the right and left sides of the lid plate downward opens that side, and the dust and the like can be discarded. At the time of this opening, the lid plate is elastically received by the downward pushing of the lid plate because the upward biasing force is exerted by the elasticity of the position restricting device provided between the lid plate and the frame. Here, basically, the rotation of the lid plate does not need to exceed 90 degrees from the reference position, and the opening can be made within a certain range due to the elastic limit of the elastic body and the like. Thereafter, when the downward pushing force is removed, the lid plate rotates upward due to the urging force of the elastic body and attempts to return to the reference position. Here, if one side of the lid plate is rotated upward beyond the reference position, the other side of the lid plate is rotated downward, and the downward rotation of the other side is the other side. Since the biasing force acts upward at the same time as being elastically received by the position restricting device, one side of the former of the lid plate is eventually pushed back downward, and the biasing force of the left and right elastic bodies acting on the lid plate Are balanced, and the lid plate stably and early closes the opening of the frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention is shown in FIGS.
This will be described with reference to FIG. In FIG. 1, reference numeral 1 denotes a container, and 2 denotes a lid. The cover 2 includes a cover plate 20, a frame 10, and a leaf spring 70. The cover plate 20 has a top surface 20a of an arcuate curved surface, and a pair of front and rear reinforcing walls 20b, 20b hanging from a front line and a back line of the top surface 20a. The frame 10 has an upper surface opening 10a that accommodates the lid plate 20 and serves as a dust inlet. The top surface 10b of the frame body 10 located around the upper surface opening 10a is formed in a curved surface so as to be flush with the top surface 20a of the lid plate 20 at a reference position where the lid plate 20 is in a horizontal state. . Pivot holes 12 are provided in the vicinity of the upper end of the center portion in the left-right direction of the front and rear inner surfaces 10c, 10c of the frame body 10, respectively. On the other hand, each of the reinforcing walls 20b, 20b at the front and rear of the cover plate 20 is formed with a pivot shaft 23 which fits into the pivot support hole 12 at the center in the left-right direction. As shown in FIGS. 1 and 3, by attaching the cover plate 20 to the frame body 10, the cover plate 20 is pivotally supported by the frame body 10 so as to rotate around a center line bisected to the left and right. You. Further, as shown in FIG. 2, below the pivot hole 12 on the front inner surface of the frame 10, there is provided a support base 60 projecting in the horizontal direction, and a slit 60 a is provided at the center of the support base 60. These are formed integrally with the frame 10. The leaf spring 70 has, at its center, a fixed portion 70a that fits into the slit 60a, a right extension 71 extending diagonally upward from the right side, and a left extension portion extending diagonally upward from the left side. 7

The cover plate 20 rotates downward to the elastic tolerance of the leaf spring 70. When the downward pressing force is removed, the cover plate 20 attempts to return to the reference position by the elastic force of the left extension 72. However, at this time, the left side of the lid plate 20 may rotate upward from the reference position due to the recoil of the spring, and the flat portion 72a may be separated from the contact portion 21 on the left side of the lid plate 20. In this case, on the contrary, the right side of the cover plate 20 rotates downward, and the rotation is elastically received by the flat portion 72a of the right extension 71 similarly to the left side. Is restrained from turning upward. Of course, the same applies to the case where the right side of the cover plate 20 is pushed downward.

That is, in order to open the swing pawl, one side of the lid plate 20 is pushed down, and then when the downward pressing force is removed, the lid plate 20 is resiliently moved by the elastic force of the right extension 71 or the left extension 72. 20 attempts to return to the reference position at which the cover plate 20 is closed, and the right extension 71 or the left extension 72 on the other side plays the role of a damper.
Can be quickly and stably converged to the reference position, and the right extension 71 or the left extension 72 acts as a position restricting tool for the cover plate 20.
