In the cap of the present invention, the obstruction has a slope such that the slope is downward from the top of the adhered portion toward the base and has a tapered slop as shown in FIG. hard. Conventionally, as shown in FIGS. 16 and 17, since the closing portion 132 stood at a right angle, a person was liable to trip, which was dangerous, and there was also a problem that the cap was detached due to the trip of the person. The invented cap eliminates the conventional disadvantages.

[0012] Further, if the closing portion is stood at a right angle as in the prior art, as shown in FIG. 18, when the electric wire CB is pulled out, an upward force is applied to the cap 130 and the cap 130 is liable to come off. On the other hand, if the obstruction is inclined as in the present invention, as shown in FIG. 13, even when the electric wire CB is pulled out, an upward force is hardly applied to the cap 3 and the cap 3 is not easily detached. is there.
