Waterproof structure
First Claim
1. A waterproof structure for a casing of a portable device, the waterproof structure comprising:
- a first casing;
a second casing to be put together with the first casing, the second casing having a recess; and
a waterproof member formed of an elastic material to prevent water from penetrating between the first casing and the second casing,wherein the waterproof member comprises a peripheral part laid out all around a space between the first casing and the second casing, when the peripheral part is brought into contact with the recess, the peripheral part being press fitted in the recess in a horizontal direction without exerting an elastic force to the second casing in a vertical direction;
wherein the first casing comprises a restriction part configured to prevent the peripheral part from coming out of the recess, the restriction part being located at a position opposite to the peripheral part, after the peripheral part is pressed fitted in the recess of the waterproof member;
wherein the waterproof member comprises a circumferential wall part and a metal plate, the circumferential wall part bending inwardly from the peripheral part and standing upright toward the first casing, the metal plate being formed integrally in the waterproof member and bent inside the waterproof member from a flat part of the waterproof member in a direction toward the second casing, the flat part placed between the first casing and the second casing; and
wherein the circumferential wall part is guided by the first casing and the second casing.

Abstract
A waterproof structure for a casing has a first casing, a second casing to be put together with the first casing, and a waterproof member formed of an elastic material to prevent water from penetrating between the first casing and the second casing. The second casing has a recess. The waterproof member has a peripheral part which, when fitted into the recess, prevents penetration of water. The peripheral part is provided at the periphery of the waterproof member, which is laid out all around space between the first casing and the second casing. A projection engages with a dent. A restriction part of the first casing, provided at a position facing the peripheral part and protruding toward the second casing, prevents the peripheral part from coming out.

7. A waterproof structure for a casing of a portable device, the structure comprising:
-
a first casing; a second casing to be put together with the first casing, the second casing having a recess with a dent in which a projection is insertable; and a waterproof member formed of an elastic material to prevent water from penetrating between the first casing and the second casing, the waterproof member having a protruding seal part which, when fitted into the recess, prevents penetration of water and has a projection engageable with the dent when being inserted in the dent; wherein the waterproof member has a circumferential wall part standing upright toward the first casing from the protruding seal part, and partially has a metal plate provided at a position extending approximately horizontally from the circumferential wall part, wherein the metal plate has a first hook which is bent toward the second casing at a position inward of an end portion of the metal plate by a predetermined distance, and is bent toward the first casing at a position slightly outward of the inward-bent position, the first hook having an end portion protruding from the circumferential wall part; and wherein the second casing has a second hook engageable with the first hook. - View Dependent Claims (8, 9, 10, 11)
