<P>PROBLEM TO BE SOLVED: To easily check clogging of a sorting net body, and prevent interference between a guide cylinder and an inner wall part of a base body in assembling the guide cylinder on the base body. <P>SOLUTION: Window parts 60 for checking the inside of the base body are formed on both sides of the base body 2. A see-through bulging cover 61 which is curved so as to bulge to the outside is attached on the window part 60. Thereby, the clogging of the sorting net body 20 can be checked from the bulging cover 61, and by utilizing a space part of the bulging cover 61, a space for rotating an upper part side flange part 14 can be secured when the guide cylinder 10 needs to be inserted in the base body 2 in a horizontally laid state in relation to dimensions of an outer diameter R of the upper part side flange part 14 of the guide cylinder 10 and an opening width W1 of the base body 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
