PROBLEM TO BE SOLVED: To provide a wiring bush mounted on an exterior apparatus with a wiring connecting terminal and having a structure for opening a passing hole with a desired diameter without using a tool. SOLUTION: In a wiring bush for an exterior apparatus, a removable tube body 6 is provided at a surrounding wall 4 of a passing hole 3 in a case 1 with a cover 2, and a part of the tube body 6 is closed when the wiring (H) is not connected. When the wiring (H) is connected, a passing hole is opened at the closed part of the tube body 6. The inner diameter of the tube body 6 is made larger than that of the wiring (H). In addition, an elastic annular film 8 along a circumferential direction is provided in the tube body 6 in a way that the inner diameter thereof is made small. A removable knob 10 is provided at the inner circumferential part of the annular film 8 with a thin part 9 in between. Then, the tube body 6 is partly sealed with the annular film 8, the thin part 9, and the knob 10. When the knob 10 is removed, a passing hole a little smaller than the wiring (H) is opened. |
