  When the second transmission member 2 rotates clockwise, the second pressing surface 720 of the second transmission member 2 presses the slide end 610 of the first biasing member 61 leftward. Accordingly, the slide end 610 slides to the left in the long groove 510 of the lid driving member 5, and the first biasing member 61 compresses and accumulates the biasing force.

  When the pressing operation member 4 is pressed further downward than the position shown in FIG. 12, the second transmission member 2 further rotates clockwise. For this reason, the second pressing surface 720 of the second transmission member 2 further presses the slide end 610 of the first biasing member 61 leftward. The slide end 610 presses the first pressing surface 710 of the first transmission member 1 leftward. For this reason, the 1st transmission member 1 rotates clockwise.

  When the slide end 610 moves to the left from the predetermined position, the first urging member 61 rotates clockwise toward the closed urging position to release the urging force. The lid driving member 5 urged by the first urging member 61 rotates clockwise. For this reason, the 2nd cover body 32 rotates counterclockwise, and the 1st cover body 31 rotates clockwise. Accordingly, the first lid body 31 and the second lid body 32 move toward the closed position to close the accommodation space 93. At this time, the lid driving member 5 is disposed at the closed driving position. The first transmission member 1 urged by the first urging member 61 is disposed at the exit position. The second transmission member 2 pressed by the pressing operation member 4 is disposed at the entry position. The pressing operation member 4 is urged by the third urging member and moves to the pressing start position (FIG. 9).

  In the opening / closing device of the second embodiment, a part of the first transmission member 1 and a part of the second transmission member 2 constitute a part of the driving means. In other words, a part of the drive means is integrated with the first transmission member 1 and the second transmission member 2.
