Of the ribs 91 formed on the first wall 90, the ribs 91B that constitute the upper side of the front end portion of the first guide part 84 and the ribs 91C that constitute the lower side are both inclined forward and downward. doing. As described above, the width in the vertical direction 7 at the front end portion and the rear end portion of the guide portion 84 is narrower than the width in the vertical direction 7 at the center portion in the front-rear direction 8 of the guide portion 84. In other words, the first guide portion 84 has a downstream end (the front end portion) and an upstream end (the rear end portion) in the pull-out direction, and a portion other than the downstream end and the upstream end (the central portion). A narrow portion 92 having a narrow width is provided.

  As shown in FIG. 7A, the first guide portion 84 includes a rising guide portion 93 described in detail below. As shown in FIGS. 2 (A) and 6 (B), when the second receiving member 82 is pulled out from the first receiving member 81, the ascending guide portion 93 is located at the front side of the second receiving member 82. The second protrusion 85 is guided in the pulling direction, that is, in the forward direction so as to be on the upper side than the side. In the present embodiment, the ascending guide portion 93 is provided in the first guiding portion 84, but the ascending guiding portion 93 may be provided in the second guiding portion 84, or the first guiding portion 84 and the first guiding portion 84. The two guide portions 85 may be provided on both sides.

  As shown in FIG. 7A, the ascending guide portion 93 is provided continuously with the ribs 91B and 91C described above and the front end of the rib 91B on the front side of the rib 91B, and forward from the front end of the rib 91B. And a rib 91D extending obliquely upward. Further, the ascending guide portion 93 is separated from the rib 91D and includes a rib 91E at a position on the front side of the rib 91D. The ribs 91B, 91C, and 91D are examples of the lower inclined portion of the present invention. Further, the rib 91D is provided at the front end portion (downstream end portion in the drawing direction) of the rib 91B, and is an example of the upper inclined portion of the present invention.

  As described above, the rib 91B is inclined toward the front diagonally downward. That is, the rib 91 </ b> B extends so that the downstream side (front side) of the first guide portion 84 in the pulling direction is located below the upstream side (rear side).

  Further, the rib 91B is separated from the first wall 90 on the front side of the support portion 98 that reinforces the connection of the rib 91B to the first wall 90. Thereby, the front side (downstream side in the drawing direction) of the support portion 98 of the rib 91B can be elastically deformed in the direction of the arrow 99. Here, the distance between the front end of the rib 91B and the rib 91C is slightly narrower than the second protrusion 85 described later. Therefore, when the second protrusion 85 enters between the rib 91B and the rib 91C, the rib 91B is elastically deformed in the direction of the arrow 99. When the second protrusion 85 is separated from the rib 91B, the elastically deformed rib 91B is elastically deformed in the direction opposite to the arrow 99 and returns to the state shown in FIG.

  Like the rib 91B, the rib 91D is separated from the first wall 90, and is elastically deformed in the direction of the arrow 99 when the second protrusion 85 is brought into contact therewith. The rib 91D is also elastically deformed by the elastic deformation of the rib 91B in the direction of the arrow 99 even when the second protrusion 85 is not in contact with the rib 91D. The interval between the rib 91D and the rib 91C is slightly wider than the size of the second protrusion 85. Therefore, when the second receiving member 85 is pulled out to the position of the rib 91D after the second projecting portion 85 exceeds the front end of the rib 91B, the elastic deformation of the rib 91B is eliminated. Therefore, when the second protrusion exceeds the tip of the rib 91B, the user feels a click.

  Further, as described above, the first guide portion 84 is provided on the rear side of the first projection portion 83.
