A resin structure includes a first resin body, and a second resin body. The second resin body is fit to an outer surface of the first resin body while being slid to one side in a sliding direction along the outer surface of the first resin body. The first resin body and the second resin body form a water stop structural unit extending in the sliding direction in a state where the second resin body is fit to the first resin body. The water stop structural unit includes a first water stop structure in a first region located at the one side in the sliding direction, and a second water stop structure in a second region located at the other side in the sliding direction with respect to the first region.

Resin structure

A resin structure includes a first resin body, and a second resin body. The second resin body is fit to an outer surface of the first resin body while being slid to one side in a sliding direction along the outer surface of the first resin body. The second resin body includes a pair of end edge portions. The pair of end edge portions extend in inclined directions that are inclined with respect to the sliding direction, such that a gap between the pair of end edge portions in a width direction gradually decreases toward one side of the sliding direction, the width direction being orthogonal to the sliding direction and extending along the outer surface. The first resin body includes a pair of facing surfaces spaced apart in the width direction and facing each other.

A resin structure includes a first resin body having an annular first side wall portion, a second resin body having a second side wall portion, and a third resin body having a bottom wall portion and an annular third side wall portion connected to the bottom wall portion. The second resin body is assembled to the first resin body, such that an upper edge of the second side wall portion and at least a portion of an annular lower edge of the first side wall portion in a circumferential direction are aligned. The third resin body is assembled to the second resin body, such that an annular upper edge of the third side wall portion and at least a lower edge of the second side wall portion are aligned.

An electrical connection box includes a housing including a frame and a lower cover configured to be fitted to the frame in a fitting direction. At least part of the frame and at least part of the lower cover form a tubular lead-out portion. An axial direction of the lead-out portion extends along the fitting direction, and the lead-out portion allows a wire harness to be pulled out through the lead out portion, the wire harness including an end portion that is to be disposed in an inside of the housing. The lead-out portion includes harness contact portions formed on an inner peripheral surface of the lead-out portion and configured to contact the wire harness. The harness contact portions extend along the fitting direction and are spaced from one another in a circumferential direction of the lead-out portion.

Electrical connection box and wire harness

A wire harness wired to a vehicle has an electrical connection box at a terminal thereof. The electrical connection box includes an electronic component block to which a plurality of electronic components are assembled and a casing to be an assembly destination of the electronic component block. The casing has a structure in which an upper cover rotates and moves to cover an upper opening portion surrounded by an edge of a frame peripheral wall. The casing includes the frame peripheral wall having the upper opening portion, the upper cover covering the opening portion by rotational movement, and a packing to be assembled to the upper cover. The packing is assembled to a packing groove formed in the upper cover. The frame peripheral wall has a position adjusting portion for adjusting the position of the packing groove with respect to the edge of the frame peripheral wall.
