Further, the pressing portion HS1 can come into contact with the pin receiving portion CP2 of the connecting component CP, as shown in FIGS. 4 and 7. Therefore, when the horizontal slide member HS slides forward, the pressing portion HS1 presses the pin receiving portion CP2 of the connecting component CP forward, and rotates the connecting component CP forward about the lever pin Pn2. Further, the pressing portion HS1 is indirectly biased rearward by the front coil spring Sf2 via the opening/closing lever component OP and the connecting component CP (see FIG. 4). As shown in FIGS. 4, 7, 8, and 10, the pin receiving portions HS2 are formed in pairs on the left and right sides below the pressing portion HS1, and extend in the front-rear direction. Note that, as shown in FIGS. 4, 8, and 10, a long hole HS2a through which the lever pin Pn2 is inserted is formed at the upper end of the pin receiving portion HS2. Note that since the lever pin Pn2 is fixed within the lid body 120, the horizontal slide member HS can slide in the front-rear direction along the elongated hole HS2a. The bottom wall portion HS3 extends inward from the lower end of the pin receiving portion HS2, as shown in FIGS. 4, 8, and 10. As shown in FIGS. 4 and 10, the front wall portion HS4 is a pair of left and right portions, and extends diagonally upward from the left and right portions of the front end of the bottom wall portion HS3 (biasing direction of the rear coil spring Sf1).
