The wire-guiding portion may be provided obliquely downward with respect to a vertical wall of the electrical junction box body.

Abstract: 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 side cover includes third and fourth plate members to be arranged within a same geometrical plane of the outer wall. The third and fourth plate members are provided with flaps projecting from the third and fourth plate members along a widthwise direction of the groove.

Abstract: There is provided an electric junction box 1 for ensuring a watertight performance even when a harness with various thickness is applied, including a box body 2, a tubelar guide portion 6 projecting from the box body 2 and guiding a harness 7 out of the box body 2, wherein the guide portion 6 is provided with a plurality of wall portions 60, 63, divided along the axial direction of the guide portion 6, and at least one of the wall portions 60, 63 is provided with a movable spurtle 65 as a spurtle and a bending portion 64 formed between the movable spurtle 65 and the box body 2 elastically deformable in the outside direction of the guide portion 6, and wherein the inner diameter of the guide portion 6 in neutral state that the bending portion 64 is not in elastic deformation is formed to fit the harness 7 with a minimum outer diameter, and the increase of the outer diameter of the harness 7 leads the bending portion 64 to bend such that the movable spurtle 65 is pushed outward.
