摘要

PROBLEM TO BE SOLVED: To provide a pachinko ball shooting device capable of varying the tension of a ball shooting spring using the most simple adjusting mechanism without a fine adjustment unit causing an increase of the cost for disassembling and separation in recycling complicatedly incorporated structure or metal parts. SOLUTION: In this pachinko ball shooting device having variable tension of the ball shooting spring, a screw screwed inside the ball shooting spring is fitted to at least one of hooks of the ball shooting spring to thereby vary the tension of the ball shooting spring, so that the springing force of the ball is made adjustable.
