Baseball practice bat for batting practice

摘要

PROBLEM TO BE SOLVED: To provide a practice bat used by a batter for batting practice, which assists the batter to efficiently practice hitting a ball against the impact center of the bat using the practice bat. SOLUTION: A practice bat 10 is formed by substantially fully molding a core material 12 extending in the longitudinal direction with a tubular exodermis member 14. The core material 12 is locally attached to the core rod 40 having a bending rigidity lower than that of the production bat and the core rod 40 at a position corresponding to the impact center of the production bat in the longitudinal direction, and the practice is performed. The bat 10 includes an impact center simulator 42 that simulates the impact characteristics of the production bat. The exodermis member 14 has a flexural rigidity lower than that of the core material 12 and has an outer shape similar to that of a production bat. [Selection diagram] Fig. 1
