Abstract

PURPOSE: To save the material cost, by providing the support point of reel gravity center at the outside of the spring center shaft.
CONSTITUTION: A plate spring consists of a base 1, wings 2, 2, and supports 3, 3. The base 1 is a part to fix the plate spring to the inner bottom of the case 7, and a plurality of small holes 4, 4', 4" are made to fix the plate spring to the case 7. The wings 2, 2 are parts to give a suitable pressure on the reel. The external ends are supports 3, 3. Since this plate spring is narrow in width in comparison with a conventional diamond type reel support spring, the material cost is saved.
