An electrical wire jacketing configuration used in an electrical junction box herein has a body portion in which a recess is formed. The electrical wire jacketing configuration includes a gutter-shaped portion configured to pass an electrical wire therethrough, a slidable engaging portion formed in both end portions of the gutter-shaped portion in the across-the-width-direction, and is slidingly engabeable with a guide portion of the recess, and a projection extending from the gutter-shaped portion toward the recess so as to prevent possible erroneous or wrong attachment of the electrical wire jacketing configuration to the recess. The recess may have a secondary guide portion configured to proceed the projection into the recess such that the projection can engage with the recess. The electrical wire jacketing configuration to which the electrical wire is fixed slidably moves toward the recess in a longitudinal direction of the electrical wire, and thereby mates with the recess.

The present invention provides a waterproof box which has small size, high workability in its assembling, and high waterproof character. The waterproof box includes a body including a peripheral body wall which has an annular convex rim defining an opening, and a first fulcrum portion which is provided on the peripheral body wall; and a cover covering the opening and including a peripheral cover wall which has an annular chase defined by a inner wall and an outer wall and engaged with the annular convex rim, and a second fulcrum portion which is provided on the peripheral cover wall and engaged with the first fulcrum portion so that the cover rotates about the fulcrum portions. A height of a first edge of the inner wall corresponding to the second fulcrum portion is lower than that of a second edge of the inner wall adjacent to the first edge.

A wire guiding out portion structure for winding a tape includes: a gutter-shaped or inverted-gutter-shaped wire guiding wall; and a plate-shaped wire supporting wall opposed to the wire guiding wall. At least two ribs for preventing a tape from slipping arranged parallel to each other in a wire guiding out direction are provided on at least one of the wire guiding wall and the wire supporting wall. A leading rib of the wire guiding wall or the wire supporting wall is projected longer in a wire radial direction than a second rib of the wire guiding wall or the wire supporting wall. At least two ribs arranged parallel to each other in a wire guiding out direction are provided on the wire guiding wall and the wire supporting wall. The ribs of the wire guiding wall are projected in the same height in the wire radial direction.

A wire-guiding portion includes a rib protruding from an outer surface of the wire-guiding portion for tape slippage prevention. At least a rear end face of the rib defines a sloping surface intersecting at an acute angle with the outer surface at the edge of the electrical wire guiding portion. The wire-guiding portion may be provided obliquely downward with respect to a vertical wall of the electrical junction box body.

The present invention is to provide an electric junction box having an enhanced watertight performance by easily winding a fixing member from a guide portion to a plurality of electric wires. The electric junction box includes a box main body and a tubular guide portion projecting from the box main body and guiding the electric wires to an outside of the box main body. A fixing member is continuously wound from the guide portion to the electric wires after the electric wires are passed through the inside of the guide portion. The guide portion includes a rib projected outward from the guide portion for preventing displacement of the fixing member. The rib is separated from the end portion of the guide portion away from the box main body.
