Abstract
To provide electronic device, which is easily assembled and disassembled. A cup-shaped introduction tube made of a rubber type member is inserted in an introduction hole provided in a watch case. On an outer peripheral surface of the introduction tube, a convex portion having a uniform semi-arch shape in cross-section in an axial direction is integrally formed. A metal pipe is inserted into the introduction tube, and an outer diameter of the metal pipe and an inner diameter of the introduction tube have a relationship of close fit before insertion. Furthermore, at an end portion of the metal pipe, a brim-shaped edge portion is formed. A ring groove is formed on a cup bottom surface of the introduction tube. In the ring groove, an annular O-ring made of a rubber type member is sandwiched. The O-ring has substantially the same inner diameter as the diameter of a shield line, and the O-ring forms a seal surface among the shield line, the metal pipe, and the ring groove in a crushed state. Furthermore, the shield line is inserted in the watch case while passing through the introduction tube, the rigid pipe, and the O-ring.
