摘要

PROBLEM TO BE SOLVED: To provide a reinforcement material provided in a hollow part of a resin frame member to reinforce the resin frame member.SOLUTION: A reinforcement material 5 can change between a first state in which first and second reinforcement materials 5a and 5b are brought close to each other by movement means 5c, and a second state in which they are taken away from each other. The reinforcement material 5 in the first state is provided in a hollow part 26 of a resin frame member 2b. The reinforcement material 5 is put into the second state from the outside of the hollow part 26. Thus, the reinforcement material 5 is brought into contact with upper and lower inner surfaces 26a and 26b of the hollow part 26 to reinforce the resin frame member.
