自己保持しうるから、アルミ箔を巻く作業を従来
に比べて能率的に行える。 Furthermore, the protective cover of this invention is made of plastic foam and has good heat insulation properties, so it is particularly suitable as a heat insulation cover. When used as a heat insulating cover, aluminum foil is often wrapped around the outer circumference of the protective cover to block radiant heat from the outside, but the protective cover of this invention can self-hold onto the pipe by itself. The work of wrapping aluminum foil can be done more efficiently than before.
さらに、この考案の保護カバーは、耐久性があ

全体に分散され、局部的にかからないことが挙げ
られる。 Furthermore, the protective cover of this invention is durable and resistant to damage. The reason for this is that since the cylindrical segments are joined by fitting the engaging convex portion and the engaging concave portion, the degree of fitting will not deteriorate even if there is a slight dimensional change. Since the concave portion and the engaging convex portion are provided perpendicularly to the direction of separation/coupling, the force during separation/coupling is dispersed over the entire cylindrical body and is not applied locally.
