Abstract

PURPOSE: To easily mold and assemble a protective structure, by incorporating a plastic or flexible protective cover to a main frame made of a flat board frame.
CONSTITUTION: A main frame is arranged by connecting flat board frames 6, 7 made of steel plates by means of stud bolts 16W18 while a protective cover 15 for protecting a taking-up motion 3 from falling water, etc. from upper portions is formed with plastic materials such as plastic or elastic materials such as hard rubber, and both side edges of the protective cover 15 are pushed to the flat board frames 6, 7 under a condition that the cover is supported by means of the stud bolts 16W18. Consequently, since the protective cover 15 is incorporated to the flat board frames 6, 7, the contact plane of the cover 15 can be simplified, and molding work is made easy while only the protective frame 15 may be inserted between two flat board frames 6, 7 by utilizing the stud bolts 16W18, thus easily performing assembly work.
