たものである。[Means for Solving the Problems] However, the present invention has a structure in which the lid is attached to the main body case via the pivot shaft and the opening spring force is applied to the lid. An arc-shaped stay base end that engages the tip side with the main body case when the lid is fully opened is installed near the biasing position, and when the lid is fully closed, the arc-shaped stay inner peripheral edge centering on the rotation fulcrum shaft has a substantially entire length. An arc-shaped guide having substantially the same length as the stay extending along is formed in the main body case.
「作用」 従って本考案によれば、蓋全閉時は開放バネ力が最大に

動作を行い得るものである。[Operation] Therefore, according to the present invention, the opening spring force becomes maximum when the lid is fully closed, but at this time, the line contact length between the stay and the guide becomes the longest, and this maximum opening spring force is applied to the entire stay. Since it can be easily prevented from being deformed by being constantly urged to open, the lid can be closed and held stably and securely without rattling, while the lid approaches the fully open position when the lid is opened. However, the length of the line contact between the stay and the guide is shortened accordingly, and it can be pulled out satisfactorily without obstructing the action of opening the spring lid, allowing smooth opening and closing of the lid. It can be done.

果を奏するものである。[Advantages of the Invention] As is apparent from the above embodiments, according to the present invention, the lid (5) is attached via the pivoting fulcrum shaft (7) of the main body case (3) and the opening spring ( 8) In a structure for urging a force, an arcuate stay (around the opening of the lid (5) near the urging position of the lid (5) for engaging the distal end side with the main body case (3) when the lid (5) is fully opened ( 14) While installing the base end,
When the lid (5) is fully closed, an arc-shaped guide (17) having substantially the same length as the stay (14) along the substantially entire length at the inner peripheral edge of the arc-shaped stay (14) centered on the rotation fulcrum shaft (7). ) Is formed on the main body case (3), and the force of the opening spring (8) becomes maximum when the lid (5) is fully closed, but at this time, the line contact between the stay (14) and the guide (17). Since the length is the longest, and this maximum opening spring (8) force is received by the entire stay (14), it is possible to easily prevent deformation of the lid (5) which is always urged to open, and at the same time, It can be kept stable and secure without rattling. On the other hand, when the lid (5) is opened, the force of the opening spring (8) becomes smaller as the lid (5) approaches the fully open position. The length of the line contact between the stay (14) and the guide (17) is also shortened, and the action of opening the lid (5) of the spring (8) is not obstructed, which is favorable. Can be pulled out, lid (5)
It has a practical effect such that the smooth opening / closing operation can be performed.
