あった。As shown in FIG. 2, a plate-shaped spring 7 is attached to the inner diameter of the body, and the pin-shaped part 3 attached to a part of the body pushes the front lid to apply force to the front lid to open and close the front lid. There was something.
上記のような表ぶた開閉機構では、板状のばねを装着
する部分が限定されたり、形状が限定されたり、板状ば
ねの押動する力の変化量が大きいなどの欠点を有してい
た。The above-described front lid opening / closing mechanism has drawbacks such as a limited portion for mounting the plate-shaped spring, a limited shape, and a large amount of change in the pushing force of the plate-shaped spring. .
上記課題を解決するために、本考案においては、ピン
状部品の押動を板状のばねから、コイルばねにすること
により安定したピン状部品の押動する力を出せるように
した。In order to solve the above-mentioned problem, in the present invention, a pin-shaped component is pushed by a plate-shaped spring instead of a coil spring so that a stable pushing force of the pin-shaped component can be generated.
上記の様な構造によれば、安定した表ぶたの開閉をす

態を維持している。In FIG. 1, 1 is a waterproof packing having a tightening margin,
Reference numeral 2 is a coil spring, and 3 is a pin-shaped component having a head portion 3a, which is slidably mounted in a hole provided in a case body 4 of a watch case via the waterproof packing. Pin-shaped part 3
A coil spring 2 is provided between the inside of the head 3a and the body 4. A front lid 5 is rotatably held by a body 6 on a body 4 to form a hinge portion. Further, the front end of the front lid 5 on which the pin 6 is formed is composed of an inner end A and an outer end B which form 90 ° with each other. The inner end portion A abuts on the portion 3a, and in the closed state, the inner end portion A abuts, and the respective states are maintained by the spring force of the coil spring 2.

閉じた状態に維持される。Next, the opening / closing operation of the front cover will be described. When the front lid is opened, the front lid 5 rotates clockwise around the pin 6, which is the rotation fulcrum. With this rotation, the inner end A of the front lid slides on the surface of the head 3a of the pin-shaped component 3 and pushes the pin-shaped component 3 into the hole of the body 4 against the elasticity of the coil spring 2. Move. When the outer end B of the front cover finally comes into contact with the head 3a of the pin-shaped component 3, the lid opening operation is completed. At this time, the front lid is kept open by the spring force of the coil spring 2. Also, when closing the front lid,
The front lid 5 rotates counterclockwise as opposed to when it is opened, and the outer end B of the front lid slides on the surface of the head 3a of the pin-shaped component 3,
The pin-shaped component 3 moves so as to push it into the hole of the body 4 against the elastic force of the coil spring 2. When the inner end A of the front cover finally comes into contact with the head 3a of the pin-shaped component 3, the lid closing operation ends. At this time, the front lid is kept closed by the spring force of the coil spring 2.

表ぶたの開閉を行なうことができるという効果がある。As described above, the present invention has a simple structure in which a coil spring is used to push a pin-shaped component, which enables stable push-motion of the pin-shaped component. The front lid can be opened and closed in a stable manner because it opens gently against the spring force, and when it closes, it closes quietly due to the restoring force of the spring force.
