Abstract

PURPOSE:To obtain the title device with high grade and pleasant operating feeling capable of smooth opening/closing action by abutting one edge of the notch part of a rib formed in a single body on a cover at the time of closing the door of the cover to a spring energizing the cover in a door opening direction, and increasing a spring pressure intensity. CONSTITUTION:A cover 2 is freely turnably supported with shafts to a main body 2, a supporting shaft 2a to support a spring 3 in one side surface and a cylindrical rib 2b are provided in a signal body in the circumference, and at the position where a fixed arm 3a and a movable arm 3b of the spring 3 pass through, notch parts 2c and 2d are provided. A rib 2b covers the majority of the coil outer circumference of the spring 3, and even when the rib is looked out of the aperture part of the cover 2, a coil part is not exposed. One edge of the notch part 2c abutted on the root of the movable part 3b and a door is opened at this side of the cover 2, and then, the movable arm 3b is bent and an energizing force extremely rises. Thus, a door opening action is facilitated, thereafter, only the spring pressure due to the twisting of a usual coil is returned, therefore, the device requires only the force sufficient to stand the dead load of the cover 2.
