PROBLEM TO BE SOLVED: To improve strength and safety in a joint member.SOLUTION: A joint member 1 for joining n bar-shaped members includes n cylindrical parts 1a and connection parts 1d. Each of the cylindrical parts has at a front end thereof an insertion opening 1c which permits insertion of the bar-shaped member. The connection parts are designed to connect a front end of an n-2th cylindrical part and a rear end of an n-1th cylindrical part 1a, connect a front end of the n-1th cylindrical part 1a and a rear end of an nth cylindrical part 1a, and connect a front end of the nth cylindrical part 1a and a rear end of a first cylindrical part 1a. Here, n is a natural number of 3 or more.SELECTED DRAWING: Figure 4
