As shown in FIG. 7, each backlash filling portion 21 has a small rib shape extending from the front end of the hood portion 11 to the front surface of the back wall 12, and as shown in FIG. In order to fill a gap between the inner surface of the wall 16 and the outer surface of the ceiling wall 38 of the lever accommodating portion 35, the protrusion 16 has a protruding dimension that is the same as or slightly larger than the vertical width of the gap. Further, on the left and right sides of the inner surface of the upper wall 16 of the hood portion 11, there are provided square rib-shaped entry protrusions 22 extending in the front-rear direction. The protrusion dimension of the approach protrusion 22 is sufficiently larger than the protrusion dimension of the backlash filling part 21.

  Furthermore, a plurality of inclination regulating portions 80 are provided on the inner surface of the upper wall 16 of the hood portion 11 so as to protrude from the left and right central portions. The inclination restricting portions 80 are arranged in parallel to each other in the vicinity of the cam follower 17. The backlash filling unit 21 is disposed on both the left and right sides of each inclination regulating unit 80.

  As shown in FIG. 6 and FIG. 7, each inclination restricting portion 80 is disposed on the left and right sides of the middle inclination restricting portion 81 disposed at the left and right center of the upper wall 16 of the hood portion 11 and the middle inclination restricting portion 81. And a pair of end side inclination restricting portions 82. The middle side inclination restricting portion 81 is disposed at a position overlapping the cam follower 17 in the front-rear direction, and is configured in a small rib shape extending in the front-rear direction in front of the cam follower 17 on the inner surface of the upper wall 16 of the hood portion 11. Has been. The middle side inclination regulating portion 81 has a rectangular cross section, and the tip is a flat surface 83 along the left-right direction. The front end of the middle side tilt restricting portion 81 faces the front end side of the upper wall 16 of the hood portion 11, and the rear end of the middle side tilt restricting portion 81 is integrally connected to the front end at the left and right center of the base end portion 19 of the cam follower 17. Has been.

  The pair of end-side inclination restricting portions 82 is configured in a small rib shape extending elongated in the front-rear direction on both sides of the cam follower 17. Each end-side inclination restricting portion 82 has a rectangular cross section, and the tip is a flat surface 83 along the left-right direction. The front end of each end side inclination restricting portion 82 faces the front end side of the upper wall 16 of the hood portion 11, and the rear end of each end side inclination restricting portion 82 is integrally connected to the front surface of the back wall 12 of the hood portion 11. ing. Further, middle portions in the front-rear direction of each end-side tilt restricting portion 82 are disposed on the left and right sides of the base end portion 19 of the cam follower 17 at a distance from the cam follower 17.

  The left-right width of the middle-side tilt restricting portion 81 is larger than the left-right width of the end-side tilt restricting portion 82, and the left-right width of the end-side tilt restricting portion 82 is larger than the left-right width of the backlashing portion. The projecting dimension of the middle-side tilt regulating part 81 is the same as the projecting dimension of the end-side tilt regulating part 82, and is the same as the projecting dimension of the backlash filling part 21 or larger than the projecting dimension of the backlash filling part 21. That is, the inclination restricting portion 80 has a function of closing a gap between the inner surface of the upper wall 16 of the hood portion 11 and the outer surface of the ceiling wall 38 of the lever accommodating portion 35. In addition, the front end of each inclination control part 80 is the slope 84 which inclines continuously with the guide surface 24 in the front end of the hood part 11. As shown in FIG.

The above is the structure of the first embodiment, and subsequently, the fitting operation of the first and second housings 10 and 30 will be described.
Prior to performing the fitting operation of the first and second housings 10 and 30, the lever 50 is retained in the initial position with respect to the second housing 30. In the initial position, the operation portion 53 of the lever 50 is disposed so as to protrude rearward of the housing body 31, and the inlet of the cam groove 55 is disposed facing forward.

  Subsequently, as shown in FIG. 2, the housing main body 31 of the second housing 30 is shallowly fitted into the hood portion 11 of the first housing 10. Then, the cam follower 17 is inserted into the entrance of the cam groove 55 through the introduction portion 44. Further, when the entry protrusion 22 enters the entry portion 45 and interferes with the tip of the elastic arm 56, the elastic arm 56 is bent and deformed in a direction away from the holding portion, and the lever 50 is rotated to the fitting position. It becomes ready to move. Here, the lever 50 is rotated toward the fitting position while holding the operation portion 53. In the turning process of the lever 50, the main body 18 of the cam follower 17 slides on the groove surface of the cam groove 55, and a cam mechanism is exhibited between the lever 50 and the second housing 30, and the first and second housings 10. , 30 fitting operation proceeds.

In the fitting process of the first and second housings 10 and 30, the bearing portion 52 slides on the outer periphery of the support shaft 41, and the plate surface of the cam plate 51 is displaced along the main body wall surface 36 of the lever housing portion 35. It is done.
Further, in the process of fitting the first and second housings 10 and 30, the backlash filling portions 21 provided on the left and right sides of the upper wall 16 of the hood portion 11 slide on the outer surface of the ceiling wall 38 of the lever accommodating portion 35. The backlash between the hood portion 11 and the housing body 31 is performed in the vertical direction perpendicular to the front-rear direction.

  By the way, since the backlash filling portion 21 is not provided in the left and right center portion of the upper wall 16 of the hood portion 11, conventionally, the operating force of the lever 50 acts on the fitting shaft in the front-rear direction passing through the support shaft 41. By doing so, the left and right center portions of the ceiling wall 38 of the lever accommodating portion 35 are elastically displaced toward the inner surface side of the upper wall 16 of the hood portion 11, and the cam plate 51 may be tilted so as to be lifted with its front end portion as a substantial fulcrum. was there.

  However, in the case of the first embodiment, in the process of fitting the first and second housings 10 and 30, the inclination regulating portion 80 protruding from the inner surface of the hood portion 11 is moved back and forth on the outer surface of the ceiling wall 38 of the lever housing portion 35. By sliding along the direction, lifting of the cam plate 51 on the operation portion 53 side is suppressed. Specifically, as shown in FIG. 1, the right and left center on the outer surface of the ceiling wall 38 of the lever accommodating portion 35 at a position immediately above the tip (flat surface 83) of the middle side inclination regulating portion 81 faces the tip of the support shaft 41. And the front end (flat surface 83) of the end side inclination restricting portion 82 abuts on both the left and right sides of the contact area of the middle side inclination restricting portion 81 on the outer surface of the ceiling wall 38 of the lever accommodating portion 35. Lifting of the cam plate 51 on the operation portion 53 side is restricted. As a result, the second housing 30 is also prevented from being inclined with respect to the first housing 10, and the fitting posture of the first and second housings 10 and 30 is stabilized.

  When the lever 50 is rotated to the fitting position and the main body portion 18 of the cam follower 17 reaches the rear end side of the cam groove 55, the lock portion 54 elastically locks the lock receiving portion, and the first and second housings. 10 and 30 are held in the fitted state. During the turning operation of the lever 50, the state in which the tilt restricting portion 80 is in contact with the outer surface of the ceiling wall 38 of the lever accommodating portion 35 is maintained, and the cam plate 51 is prevented from being lifted. As a result, the first and second housings 10 and 30 are brought into the mating positions in the normal state, and the front surface of the housing body 31 faces the rear wall 12 of the hood portion 11 substantially in parallel as shown in FIG. Arranged. Note that the operation portion 53 of the lever 50 is disposed so as to reduce the amount of rearward protrusion from the housing main body 31 in the process of moving to the fitting position, and to contact the rear end of the housing main body 31 at the fitting position.

  As described above, in the case of the first embodiment, the inclination regulating portion 80 projecting from the inner surface of the upper wall 16 of the hood portion 11 comes into contact with the outer surface of the ceiling wall 38 of the lever accommodating portion 35, so that the cam plate Since the inclination of 51 is suppressed, the inclination fitting of the first and second housings 10 and 30 can be prevented. In particular, since the tilt restricting portion 80 is installed between the cam plate 51 and the inner surface of the hood portion 11 and in a region facing the support shaft 41 in the vertical direction, the tilt of the cam plate 51 is more effectively suppressed. The

  In addition, although a gap is provided between the inner surface of the upper wall 16 of the hood portion 11 and the outer surface of the ceiling wall 38 of the lever housing portion 35, the backlash filling portions 21 are provided on both the left and right sides of the outer surface of the ceiling wall 38 of the lever housing portion 35. The gap is filled, and the inclination regulating portion 80 fills the gap at the left and right central portions on the outer surface of the ceiling wall 38 of the lever accommodating portion 35. If the tilt restricting portion 80 is not provided, a gap is interposed between the left and right central portions of the inner surface of the ceiling wall 38 of the lever accommodating portion 35 and the inner surface of the hood portion 11 to induce the tilt of the cam plate 51. Since there is concern, the merit of restricting the inclination of the cam plate 51 by the inclination restricting portion 80 is great.

  In addition, since the tilt regulating portions 80 extend in a plurality in the front-rear direction, the cam plate 51 can be more reliably prevented from tilting, and manufacturing dimensional management is facilitated. . And since the inclination control part 80 is protrudingly provided by the inner surface of the food | hood part 11, the form of the inclination control part 80 can be maintained stably.

  Furthermore, since the middle side inclination restricting portion 81 is disposed at a position overlapping the cam follower 17 in the front-rear direction, the cam follower 17 can be used as a reference for the formation position of the middle side inclination restricting portion 81, and the inclination of the cam plate 51 can be reduced. The structure to regulate can be secured.

  Furthermore, the second housing 30 is provided with a lever accommodating portion 35 that accommodates the cam plate 51, the support shaft 41 projects from the inner surface of the lever accommodating portion 35, and the tilt restricting portion 80 is connected to the outer surface of the lever accommodating portion 35. Unlike the case where the cam plate 51 is provided with the tilt regulating portion 80, the tilt regulating portion 80 is not affected by the rotation of the lever 50 because the gap with the inner surface of the hood portion 11 is filled. The reliability which prevents the inclination fitting of the 1st, 2nd housings 10 and 30 can be improved.

And a pair of end side inclination regulating portions 82A. 81 A of middle side inclination control parts are arrange | positioned on the outer surface of the ceiling wall 38 of the lever accommodating part 35 behind the introduction part 44 so that it may overlap with the introduction part 44 in the front-back direction. The rear end of the middle side inclination regulating portion 81 </ b> A is integrally connected to the front end of the reinforcing rib 42. The front end of the middle side inclination regulating portion 81 </ b> A faces the rear end at the center of the left and right of the introduction portion 44.

  The pair of end side inclination restricting portions 82 </ b> A are arranged so as to extend in the front-rear direction so as to extend along the left and right side edges of the introduction portion 44. The front end of each end side inclination restricting portion 82 </ b> A is disposed so as to face the front end of the ceiling wall 38 of the lever accommodating portion 35 that becomes the opening end of the introduction portion 44. Further, among the end-side tilt regulating portions 82A, those located on the left and right sides (the right side in FIG. 9) are integrally connected to the front ends of the reinforcing ribs 42 at the rear end and the other left and right sides (the left side in FIG. 9). Is located so that the rear side is along the side edge of the notch 43.

  The left-right width of the middle side inclination restricting portion 81A is larger than the left-right width of the end-side inclination restricting portion 82A. The projecting dimension of the middle side tilt restricting part 81A is the same as the projecting dimension of the end side tilt restricting part 82A, and is formed between the inner surface of the upper wall 16 of the hood part 11 and the outer surface of the ceiling wall 38 of the lever accommodating part 35. The vertical width of the gap is the same as or slightly larger than the vertical width of the gap. In other words, the inclination restricting portion 80A has a function of closing a gap between the inner surface of the upper wall 16 of the hood portion 11 and the outer surface of the ceiling wall 38 of the lever accommodating portion 35. This is the same as in the first embodiment.

  In the fitting process of the first and second housings 10 and 30, the backlash filling portion 21 provided on the upper wall 16 of the hood portion 11 slides on both the left and right sides of the outer surface of the ceiling wall 38 of the lever accommodating portion 35. The backlash between the portion 11 and the housing body 31 is made. In addition, the tilt restricting portion 80A provided at the left and right center portion on the outer surface of the ceiling wall 38 of the lever accommodating portion 35 slides on the inner surface of the upper wall 16 of the hood portion 11, so Lifting is suppressed. Specifically, as shown in FIG. 8, the front end (flat surface 83 </ b> A) of the middle side inclination regulating portion 81 </ b> A contacts the inner surface of the upper wall 16 of the hood portion 11 at a position directly above the front end of the support shaft 41. The tip (flat surface 83A) of each end-side tilt restricting portion 82A comes into contact with the left and right sides of the contact area of the middle-side tilt restricting portion 81A on the inner surface of the upper wall 16 of the hood portion 11, thereby lifting the cam plate 51. Is regulated. Further, each inclination regulating portion 80A is maintained in a state where it can abut on the inner surface of the upper wall 16 of the hood portion 11 throughout the entire rotation process of the lever 50. As a result, the fitting posture of the first and second housings 10 and 30 is stabilized, and the tilt fitting of the first and second housings 10 and 30 is effectively prevented.

  In the case of the second embodiment, since the inclination restricting portion 80A protrudes from the outer surface of the ceiling wall 38 of the lever accommodating portion 35, the form of the inclination restricting portion 80A can be easily confirmed. Further, since the middle side inclination restricting portion 81A is disposed at a position overlapping the introduction portion 44 in the front-rear direction, the introduction portion 44 can be used as a reference for the formation position of the middle side inclination restricting portion 81A. A structure that regulates the inclination can be secured.
