<p>PURPOSE:To provide a protection cover with which an installed electric wire bent in an arcuate shape is easily covered by a method wherein a bellows-form cylinder made of synthetic resin is longitudinally divided, bellows-form guide protrusions are openably positioned facing each other at the outside along a division end and the tips thereof are nipped by a hook-form part. CONSTITUTION:Large protrusion parts 2 and small recessed parts 3 are alternately arranged to form a bendable bellows-form cylinder body 1 longitudinally bendable. The cylinder body 1 is longitudinally linearly divided and bellows-form guide protrusions 5 and 6 to introduce an electric wire are positioned facing each other at the outside of the cylinder body 1 extending along the division end 4. A lock protrusion piece 7 is extended to the lower end of one bellows guide protrusion 6, a hook-form part 8 to nip the tips of the guide protrusions 5 and 6 is erected from the tip of the lock protrusion piece 7 to manufacture an electric wire protection cover A. This constitution spreads the bellows-form guide protrusions 5 and 6 by unhooking of the hook-form part 8, facilitates insertion of an electric wire by spreading the division end 4, and prevents entrance of branches and leaves by closing together the guide protrusions 5 and 6.</p> |
