<p>PURPOSE:To provide a joint box for wiring in which a perfect insulation cover is obtained by simply applying the joint box which can be easily pulled out by a constitution wherein a plurality of insulating and resilient ON/OFF valves are fixed integrally slightly in the rear of the opening of joint box so that the wire bundle can be disposed at a position spaced apart from a structural member. CONSTITUTION:When a wire bundle is inserted substantially vertically through the opening 2 of a joint box 1 for wiring, an ON/OFF valve 3 advances rearward while being enlarged and abuts on a recess or a level difference of the wire bundle which is thereby dielectrically wrapped. When the joint box 1 is pulled out, the box 1 is pulled substantially vertically to retract the ON/OFF valve 3 toward the opening while enlarging and then the ON/OFF valve 3 is closed to be used again. This structure allows application of joint box by groping even in a limited dark space.</p> |
