PROBLEM TO BE SOLVED: To solve a problem of taking great trouble in putting an arrowhead in an arrow used for Japanese archery by striking the arrow with all the strength to mount the arrowhead or inserting hemp, and a problem of rusting the arrowhead if the arrow is used in a practice or the like in rain due to an aluminum material. SOLUTION: The arrowhead is structured to be smoothly put in and hard to come off by forming the internal structure of the arrowhead in tapered shape in mounting the arrowhead to the arrow for Japanese archery. The arrowhead is hard to rust and resistant to wear by forming it of stainless steel. COPYRIGHT: (C)2009,JPO&INPIT
