Abstract

PURPOSE:To make the waterproofness between a cable cover and a signal transmitting cable perfect by providing an annular clamp bringing the cover and the cable to a pressure contact state to the outer periphery of the part exposed from the case main body in the cable cover of the signal transmitting cable. CONSTITUTION:A cable 9 is inserted in and arranged to the lower opening end of a case main body 2 and a clamp 18 is provided to the part exposed from the main body 2 of the cable cover 10 made of a waterproof material protecting the cable 9. Since the annular contact part 18a of the clamp 18 is brought into contact with the cover 10 under pressure and the inner peripheral part 10b of the cover 10 comes into close contact with the outer periphery of the cable 9, the waterproofness between the cover 10 and the cable 9 becomes perfect. Further, the outer periphery of the contact part 18a is opened only by simple operation grasping a pair of the grasping pieces 18b, 18c of the clamp 18 and a clamped state can be released. By this simple constitution, the waterproofness between the cable 9 and the cover 10 can be perfectly achieved. Further, the cable 9 is fixed at a constant position by the clamp 18 and the core of the cable 9 can be set to an immovable state.
