For providing a waterproof box, which can prevent penetration of liquid like water through a gap between a box main body and a cover member mounted on the box main body, the waterproof box includes the box main body having an opening formed by surrounding with a plurality of side-walls, a lid mounted on the box main body for covering the opening, a grommet, and a seal member formed into a ring shape to be mounted on the lid for waterproofing between the box main body and the lid. A cutout side-wall has a cutout. The grommet to be mounted on the box main body fills the cutout. The seal member has a contact portion to abut on an edge of the cutout side-wall. A thickness of the contact portion is formed thicker than that of the other portion of the seal member.

What is claimed is: 1. A waterproof box comprising: a box main body having an opening formed by a plurality of side-walls surrounding the opening, wherein at least one cutout side-wall from among the plurality of side-walls is provided with a cutout formed by cutting said at least one cutout side-wall to be apart from an edge thereof close to the opening; a lid mounted on the box main body so as to cover the opening by being mounted on the box main body; a rubber seal member formed into a ring shape, and attached on one of the box main body and the lid so as to be deformed elastically for waterproofing between the box main body and the lid by abutting on edges of side-walls; and a cover member mounted on the box main body so as to cover the cutout by being mounted on the box main body, wherein a width of a contact portion of the rubber seal member, which abuts on the edge of the cutout side-wall provided with the cutout, is wider than that of a remaining portion of the rubber seal member other than the contact portion, and wherein the contact portion of the rubber seal member comprises a contact surface, which is slanted both in a vertical mounting direction of mounting the lid upon the box main body and in a perpendicular direction perpendicular to the vertical mounting direction so as to abut both on the edge of the cutout side-wall and the cover member, formed in a full length of said contact portion. 2. The waterproof box according to claim 1, wherein the contact portion of the rubber seal member comprises: a seal main body having a thickness and a width which is the same as a thickness and a width of the remaining portion; a first projecting body projecting from the main body toward the cutout side-wall; and a second projecting body projecting along the perpendicular direction from the first projecting body toward an outside of one of the box main body and the lid. 3. The waterproof box according to claim 2, wherein the contact surface is slant along the perpendicular direction to become closer to the edge of the cutout side-wall in accordance with a position approaching an outside of one of the box main body and the lid. 4. The waterproof box according to claim 3, wherein the contact portion of the rubber seal member comprises: a seal main body having a thickness and a width which is the same as a thickness and a width of the remaining portion; a first projecting body projecting from the main body toward the cutout side-wall; and a second projecting body projecting along the perpendicular direction from the first projecting body toward an outside of one of the box main body and the lid.
