By the way, small electronic devices such as mobile phones are often used in places that are easily exposed to water, such as outdoors, outdoors, and bathrooms. Therefore, it is particularly important to ensure a waterproof structure for internal devices. It has become one of.

For this reason, techniques related to a waterproof structure of a small electronic device such as a portable telephone have been proposed. For example, a waterproof handset structure disclosed in Japanese Utility Model Laid-Open No. 62-146350 and Japanese Patent Laid-Open No. Sho 62-177152. There are various types such as a telephone having a waterproof structure and a wireless handset for telephone set of Japanese Utility Model Publication No. 3-9407.

[0012] The waterproof structure described in these publications has a structure in which internal equipment is provided by disposing a waterproof packing or a waterproof cloth in a fitting portion, a transmitting / receiving portion, or an operation button portion of the upper and lower casings constituting the telephone. It was to keep it confidential from the outside and ensure waterproofness.

Such a waterproof structure is also used in flip-type portable telephones, but in the case of flip-type telephones, the waterproof structure of the button portion becomes a problem. That is, as described above, in a flip-type telephone, the hook portion must be configured to be movable by a button, whereas a waterproof structure for such a movable portion is generally difficult.
