The guard body disclosed in Patent Document 1 can alert the driver of a vehicle including a passerby or a light vehicle such as a bicycle that there is a gutter near the road, and the passerby or the like falls into the gutter. We are trying to prevent accidents by doing this,
(1) Obstacles that overflow from the gutters along with the turbid flow during heavy rain may flow out onto the road over the guard body and hinder vehicle driving.
(2) The mesh body is supported by the support part of the support material attached to the gutter at regular intervals in the longitudinal direction of the gutter. Easy to stay in
(3) If the support material is omitted, it will be somewhat difficult for obstacles to stay inside the mesh, but the strength of the mesh alone is weak, and light vehicles such as bicycles can pass over it as well as vehicles. It is impossible or difficult, and if you try to pass by force, the mesh body may bend and deform or be damaged.
(4) In order to prevent the arched or mountain-shaped mesh body from protruding onto the road and obstructing the passage of vehicles, the guard body must be tilted to some extent toward the gutter, and the guard body must be attached to the gutter. The angle is limited,
(5) It is necessary to process the mesh body into an arch shape or a mountain shape.

(2) The grating has a plate-like lattice shape and is projected from the side wall on the road side, and has a simple structure, and it is possible to make the height from the gutter higher than that of the mesh body described in Patent Document 1. As a result, even if the bulk of the muddy flow that overflows from the gutter during heavy rain becomes considerable, obstacles will be filtered by the grating unless the muddy flow exceeds the grating , and will flow out onto the road surface and hinder vehicle running. That there is no
(3) Obstacles filtered by grating are easily washed away by turbid flow and subsequent washing, and are unlikely to stay on the grating .
(4) Since the glazing is plate-shaped and mounted at a perpendicular or blunt angle to the road surface, it does not hinder the passage of vehicles, and if the mounting strength to the gutter is increased, the vehicle will collide. Even if this is the case, the pavement can serve as a guide to return the vehicle to the road side, preventing the vehicle from derailing into the gutter, and light vehicles such as pedestrians and bicycles will fall into the gutter. Can be prevented,
And so on.

If the grating is attached to the gutter by using the attachment means and the doglegged bracket as in the invention of claim 3, the attachment can be easily performed .
