Zusammenfassung:PROBLEM TO BE SOLVED: To provide a chain visually confirming device for a chain gate formed in an extremely simple structure and economical since the running cost is not needed. SOLUTION: This chain visually confirming device 10 for a chain gate comprises: a cylindrical body 30; a recursive reflective film 40 stamped on the outer surface of the cylindrical body 30; and cap members 50 secured to both ends of the cylindrical body 30, respectively. The outer diameter of the cylindrical body 30 is smaller than the lateral width of a chain storage groove. The cap member 50 is formed by combining a pair of cap pieces 51 with each other. A chain 21 is inserted into the cylindrical body 30. The chain 21 is held by the cap pieces 51. COPYRIGHT: (C)2009,JPO&INPIT
