Abstract:
To save the space and to securely maintain a locked state of a lid through simple operation.SOLUTION: A locking device 6 for a lid 3 covering an opening of a container 2 from above comprises: a clamp 10 which fits a flange part 4 from the outside; a clamp shaft 25 around which the clamp 10 rotates; a clamp bearing 20 which rotatably supports the clamp 10 through the clamp shaft 25; a slide part 14 which moves together with the clamp 10; and a flat plate-like circumferential movement plate 30 which is arranged at a distance around an outer periphery of the flange part 4, is movable in a circumferential direction of the container 2, and also has a guide part 31 guiding movement of the slide part 14. The clamp 10 has a channel-sectioned fitting part 11. The circumferential movement plate 30 moves toward one side in a circumferential direction to locate the slide part 14 at one end part 31a of the guide part 31, thereby bringing the clamp 10 into a fitted state, and moves toward the other side in the circumferential direction to locate the slide part 14 at the other end part 31b of the guide part 31, thereby releasing the clamp 10 from the fitted state.SELECTED DRAWING: Figure 1
