It is preferable to sandwich it between the lower end and the bottom plate 24 that seals the inner bottom portions of the pair of cylindrical bodies 20a and 20b. Then, by using the elastic force of the spring material 50, the leg portions 12a, 12 on both sides of the fence body are
A point 8 where b is to be lifted up inside the pair of cylinders 20a, 20b and the upper part of the fence body 10 should be blocked from traffic.
It is preferable to allow it to be easily projected above 0 without effort. Then, the spherical body 60 is caused to enter the cylindrical bodies 20a, 20b by using the elastic force of the elastic body 62, and the tip of the spherical body 60 is made into the leg portions 12a, 12 on both sides of the fence body.
It is preferable that the recess 28 of the lower side wall of b can be fitted and locked. Then, the lower portions of the legs 12a and 12b on both sides of the fence main body are connected to the pair of cylindrical bodies 20a and 20b.
It is good to be able to lock each inside so that it does not move.

Further, as described above, the upper portion of the fence main body 10 protruding above the portion 80 where the traffic should be cut off is pressed downward to make the spherical body 60 resist the elastic force of the elastic body 62. It is advisable to be able to retract the inside of the through hole 26. Then, the tip end of the spherical body 60 is disengaged from the recess 28 in the lower side wall of the legs 12a, 12b of the fence main body, and the legs 12a, 12b on both sides of the fence main body are locked in the pair of cylinders 20a, 20b. It is advisable to be able to release the locked state of the lower part of. It is preferable that the leg portions 12a and 12b on both sides of the fence main body can be made to invade the inside of the pair of cylindrical bodies 20a and 20b against the elastic force of the spring material 50. Then, the spherical body 60 is moved to the cylindrical body 20a by using the elastic force of the elastic body 62.
20b again, and the tip of the sphere 60 is made into a recess 2 in the side wall on the upper side of the legs 12a, 12b on both sides of the fence body.
It is better to be able to fit in and lock with 8.
The leg portions 12a and 12b on both sides of the fence body may be housed in the pair of cylindrical bodies 20a and 20b so as not to move.

Further, in the fence of the present invention, the concave portion 30 may be formed by using cement or the like in the peripheral portion of the portion where the pair of cylindrical bodies 20a and 20b are embedded.

[0055]

As described above, according to the fence of the present invention, the upper portion of the inverted U-shaped rod-like fence main body is easily held at a position where traffic should be cut off without any trouble. it can. And at the top of the fence body,
It is possible to prevent cars, etc. from passing through places where traffic should be blocked.

Further, the fence main body can be easily housed inside the place where the traffic should be cut off without trouble. At the same time, it is possible to fill the inside of the recess provided in the place where the traffic should be blocked with the joint portion of the fence main body. Then, the place where the traffic should be cut off can be made passable without being obstructed by the fence body or the recess.
