发明名称 FASTENING STRUCTURE OF PLATE MEMBER AND METHOD OF FIXING PLATE MEMBER
摘要 PROBLEM TO BE SOLVED: To easily and simultaneously insert/fit one side ends of members to be mounted such as blades, which are erected in many with the other side ends held, into inserting small holes or grooves of plate members corresponding to respective members to be mounted. SOLUTION: This fastening structure of plate members and members to be mounted is constituted so that small holes or grooves are pierced to plate members represented by side plates 3 in an impeller, end parts 2-1 of members to be mounted represented by blades 2 in the impeller are inserted into the holes or the grooves and both are held/fixed. To this end, the small holes or grooves are formed as its one side is a louvered part, by bending back the louvered part, the end parts of the member to be mounted fitted into the small holes or grooves are held/fixed. Alternatively, end part small holes are formed in the blade end parts fitted into the small holes or grooves formed in side plates, the tips due to bending back the louvered parts of the side plates are bitten into the end part small holes, thus, holding strength is increased.
