LOWER RUNNER FOR UMBRELLA AND RESIN-MADE UMBRELLA USING THE LOWER RUNNER

摘要

PROBLEM TO BE SOLVED: To constitute all parts with resin so that it can be disposed of by burning even when they are not divided into combustible and noncombustible ones.

SOLUTION: A resin-made plate spring 9 including a pair of pressing pieces 9a extending along the periphery of a lower runner body a is provided at a part of a lever L corresponding to a stop part 8. When the lever L is rotated in a direction in which the stop part 8 is detached from a recessed part or a protruding part formed on a shaft 1, distal ends of both the pressing pieces 9a of the plate spring 9 are opened along the outer circumference of the lower runner body a by the rotation force of the lever L so that spring force is exerted.
