PROBLEM TO BE SOLVED: To provide a safety fence of a belt conveyor, in which parts are prevented from being lost at an assembly/disassembly operation time.SOLUTION: An attachment bracket 20 is constituted of an outer part 20A and an inner part 20B, and a U-shaped engaging ring 20E is protruded outward from the outer part. A cotter 21 shaped to have a side face narrowed downward is inserted into the engaging ring, and a release stop pin 21A is disposed at a lower end part of the cotter. A wide portion of an upper end part is auctioned with a U-shaped groove side edge of the engaging ring thereby to stop a downward release so that they can be inclined around the release stop pin at a lower end abutting against the U-shaped groove side edge of the engaging ring.SELECTED DRAWING: Figure 4 |
