PROBLEM TO BE SOLVED: To provide a marker unit simply assembled in one operation, easy to fold and having good workability. SOLUTION: This marker unit 1 having a nearly equilateral triangular shape is provided with a bottom side member 2 and a first side member 15 and a second side member 23 at both ends of the bottom side member 2. One end of the first side member 15 and one end of the second side member 23 are rotatably arranged at both end sections of the bottom side member 2 so that both side members 15, 23 can be overlappingly folded. A coupling section 19 is provided on the other end side of the shaft 17 of the first side member 15, and a coupling reception section 27 slidably coupled with the coupling section 19 is provided on the second side member 23. When the first side member 15 is rotated, the second side member 23 is interlockingly rotated. |
