PROBLEM TO BE SOLVED: To provide a structure of a new insert for trimming capable of preventing branch flows of bone particles at the time of integral-molding with resin, by improving the rigidity and strength of the insert, especially the rigidity of the bone particles without making a thickness of the insert heavier. SOLUTION: This insert 10 for trimming made of a metal plate is embedded in a rubber or synthetic resin material, and has a large number of bone particles 11 parallely arranged via gaps 13 at predetermined intervals in a width direction, and bond parts 15 connecting the bone particles in a longitudinal direction. Joint parts 16 of the bone particles to the bond parts are formed as wide parts 20. COPYRIGHT: (C)2003,JPO
