(Elastic piece 80 (biasing means))
The elastic piece 80 is a female member 20 or a male member 30, and in this embodiment, as shown in FIGS. 7 and 8, is provided integrally with the female member 20 and is inclined obliquely toward the engaging direction. It is.
Although the elastic piece 80 is integrally provided on the female member 20 side, the elastic piece 80 is not limited to this, but although not illustrated, the elastic piece 80 may be provided on the male member 30 side or an engagement protrusion 60 described later of the male member 30. .
The main features of the elastic piece 80 will be described next.
The first feature is that the elastic piece 80 is bent in contact with the male member 30 in the connected state.
First, referring to FIG. 3, the elastic piece 80 is located at the upper edge of the opening 40 in the drawing, and is located substantially at the center in the left-right width direction. The left and right sides of the elastic piece 80 can be cut and bent by a pair of left and right slits extending from the opening 40 halfway upward. The upper end side of the elastic piece 80 is at least partially overlapped with a first surface 42a to be described later of the guide surface 42 in the vertical direction of FIG. Further, the lower end portion of the elastic piece 80 slightly protrudes into the opening 40.
Next, the cross-sectional direction will be described with reference to FIG. 7. The elastic piece 80 projects obliquely downward toward the opening 40 toward the opening 40 in FIG.
Further, in the connected state, that is, in a state where the engagement protrusion 60 is inserted into the opening 40, the elastic piece 80 abuts on a later-described abutment portion 62 of the engagement projection 60, and is pressed by the abutment portion 62, When the right side in FIG. 7 is regarded as the front direction, the direction is opposite to the engagement direction, and the direction is bent forward.
At this time, since the elastic piece 80 protrudes obliquely, the urging force in two directions acts on the engaging protrusion 60 by the elastic restoring force of the bent elastic piece 80.
The first urging force causes the engagement protrusion 60 to move in the opening 40 via a contacted portion 81 (see FIG. 7) described later formed on the upper surface of the elastic piece 80 by the elastic restoring force of the elastic piece 80. It is an urging force that tries to push back toward the rear.
The second urging force tries to kick up the engaging protrusion 60 in the opening 40 in the opening 40 via the contacted portion 81 by the elastic restoring force of the elastic piece 80. It is an energizing force. As shown in FIG. 8, the second urging force in the connected state will be described later, but the convex stepped portion 61 a (engagement portion 61) on the engagement protrusion 60 side and the opening 40 side will be described later. Since the concave step portion 41a (the engaged portion 41) is fitted to each other, it is received by both portions. On the other hand, when removed, that is, when the male member 30 is pushed to the right in FIG. 7, the engagement between the step portion 61a (engaging portion 61) and the step portion 41a (engaged portion 41) is released. The action of the second urging force on the engaging protrusion 60 becomes remarkable, and the engaging protrusion 60 is kicked upward toward the opening 40.
The second feature is that the elastic piece 80 or the contacted portion 81 thereof is at least partially overlapped with a first surface 42a, which will be described later, of the guide surface 42 located on both the left and right sides in FIG.
