Then, when the water level in the pipeline is increased, and as shown in FIG. 10, when the lifting body 381 is in an elevated state, the lifting permanent magnet 360 and the odor blocking permanent magnet 365 These are close to each other, compared to the attractive force between the pair of the odor blocking-side permanent magnets 365, the attractive force between each of the lifting permanent magnets 360 and the odor blocking-side permanent magnets 365 facing each other is relatively stronger. As a result, each of the lifting permanent magnets 360 facing each other and the respective odor blocking permanent magnets 365 are attracted to each other, and accordingly, the first contact portion 327 and the second contact portion 328 are each The contact between the first contact part 327 and the second contact part 328 is released while being spaced apart from each other in a direction that is relatively distant from each other, so that the odor blocking member 320 is opened.

First, until the rainwater is supplied by a certain amount or more, as shown in FIG. 9, the lifting member 380 is maintained in a lowered state, and by the attraction between the pair of the permanent magnets 365 on the odor blocking side The first contact part 327 and the second contact part 328 are brought into contact with each other, so that the odor blocking member 320 is in a closed state, and thus, the odor coming up from the pipe is prevented from the odor blocking member 320 ) To block it and prevent it from radiating to the outside of the grating.

Then, the rainwater flowing from the outside of the grating flows down along the upper surface of the odor blocking member 320 and accumulates on the upper surface of the odor blocking member 320, and is accumulated on the upper surface of the odor blocking member 320. When the accumulated rainwater is accumulated by a certain amount or more, the contact between the first contact portion 327 and the second contact portion 328 is released by the weight of the rainwater, and the odor blocking member 320 is opened. Rainwater can fall and flow into the pipeline.

On the other hand, while the odor blocking member 320 remains closed, when the rainwater fills up in the pipeline and the rainwater flows back from the pipeline due to excessive rain such as a rainy season, the water level in the pipeline rises. As shown in FIG. 10, the lifting member 380 is raised while being guided by the lifting guide member 370, and accordingly, the lifting permanent magnets 360 facing each other and the respective odor blocking sides The permanent magnets 365 are attracted to each other, so that the contact between the first contact part 327 and the second contact part 328 is released, and the odor blocking member 320 is opened and flows back from the pipeline. The rainwater can be discharged to the outside of the grating.
