Front door 2 and sliding door 3
The center pillar 5 of the vehicle body 1 is arranged between the two.
Between this center pillar 5 and the front end of the sliding door,
A lock mechanism (not shown) is provided for locking the slide door 3 when the slide door 3 is closed, and the slide door 3
A position regulating device 6 shown in detail in FIG. 1 is arranged so as to regulate the position of the slid door 3 in a direction orthogonal to the opening / closing direction when the door is closed.

In FIG. 1, the position regulating device 6 is composed of a receiving body 7 fixed to a rear mounting surface of the center pillar 5 and an engaging body 8 fixed to a front end surface of the slide door 3. As shown in FIGS. 1 and 3, the receptor 7 has a vertically elongated elongated oval shape that opens rearward, and has a substantially trapezoidal shape in which the horizontal and vertical cross-sectional shapes are tapered toward the front. Engagement recesses 9 are formed, and a plurality of mail terminals 10 are vertically projected from the rear end surface 9a toward the rear at appropriate pitch intervals. On the engagement surface 11 formed of the inner peripheral side surface of the engagement recessed portion 9, projections 12 formed of projections having a triangular cross section and extending in the front-rear direction are provided at appropriate intervals in the circumferential direction. The height of the protrusion 12 is, for example, about 0.5 mm. Reference numeral 17 denotes a mounting flange that abuts on the mounting surface 5a at the rear end of the center pillar 5, and 18 denotes mounting holes formed at the upper and lower ends thereof.

The engaging body 8 has a substantially trapezoidal engaging projection 13 whose base has a lateral cross-sectional shape that is vertically elongated and oval, and whose horizontal and vertical cross-sectional shapes are tapered toward the front. When the engaging protrusion 13 is fitted into the engaging recess 9 and engaged,
The engagement surface 14 formed of the outer peripheral side surface abuts on the top of a projection 12 provided on the engagement surface 11 of the engagement recess 9, and the projection 1
It engages with the engagement surface 11 via 2. Also, the engaging protrusion 13
A female terminal 15 into which the female terminal 10 is fitted is provided from the front end surface of the female terminal 15 toward the rear.

As the material of the receiving body 7 and the engaging body 8, for example, the receiving body 7 is made of polyacetal resin, the engaging body 8 is made of nylon resin, and the engaging projection 13 of the engaging body 8 receives the large load of a predetermined amount or more. When strongly pushed into the engagement recess 9 of the body 7, the projection 12 is crushed by the engagement surface 14 on the outer periphery of the engagement projection 13 and plastically deformed.

In the above construction, when the sliding door 3 is closed, the engaging projection 13 of the engaging body 8 on the sliding door 3 side is fitted into the engaging concave portion 9 of the receiving body 7 on the center pillar 5 side to engage with each other. The position is regulated.

At this time, due to the manufacturing and assembling tolerances of the vehicle body 1 and the slide door 3, with the slide door 3 closed and locked, the receiving body 7 and the slide door 3 on the vehicle body 1 side.
It is inevitable that variations occur in the distance between the side engaging body 8 and the variation of ± α in the mounting distance L between the receiving body 7 and the engaging body 8 as shown in FIG. . In addition,
α is, for example, about 1.5 mm.

However, as shown in FIG. 2A, even when the mounting distance is L + α, the engaging surface 14 of the engaging projection 13 is the projection 1.
By closely engaging with 2, the position of the slide door 3 is surely regulated, and there is no fear of generating abnormal noise.

Further, when the mounting distance is an appropriate distance L as shown in FIG. 2B, when the slide door 3 is closed and locked after the slide door 3 is assembled, the engaging projection 13 is engaged with the engaging recess 9. The engaging surface 14 of the engaging protrusion 13 is pushed into the inside.
Is pressed against the protrusion 12 with a load larger than a predetermined value, the protrusion 12 is plastically deformed so as to be crushed, and in that state, the engaging surface 14 closely engages with the protrusion 12 to thereby slide the slide door. The position of 3 is surely regulated, and there is no fear of generating abnormal noise.

Further, as shown in FIG. 2 (c), when the mounting distance is L-α, the engaging surface 14 of the engaging projection 13 is located on the projection 12 as in the case of FIG. 2 (b). The protrusion 12 is pressed by a load of a predetermined value or more, and the protrusion 12 is plastically deformed so as to be crushed and compressed. In this state, the engagement surface 14 closely engages with the projection 12, so that the slide door 3 is surely regulated in its position, and there is no fear of generating abnormal noise. Moreover, even in this case, the pressing load generated between the engaging recess 9 of the receiving body 7 and the engaging projection 13 of the engaging body 8 is alleviated by crushing the projecting portion 12, so that the engagement of the receiving body 7 is reduced. There is no fear that an excessive load will act on both sides of the mating recess 9 to cause cracks and damage.

Although FIG. 2 used in the above description shows the horizontal cross section in the present embodiment, the same action occurs in the vertical cross section. That is, according to the slide door position regulating device of the present embodiment, the position of the slide door 3 is properly regulated with respect to the vehicle body 1 not only in the horizontal direction but also in the vertical direction. Of course, the protrusion 12 may be provided only on the side surface of the engagement surface 11, and the upper and lower surfaces may be omitted.

In this embodiment, the protrusion 12 is crushed and plastically deformed. However, if the combination of the materials of the receiving body 7 and the engaging body 8 is appropriately selected, the engaging protrusion 1 can be formed by the protruding portion 12.
It is also possible that the engaging surface of the outer periphery of 3 is scooped and plastically deformed.

A combination of materials of the receiving body 7 and the engaging body 8 is such that the outer peripheral surfaces of the projecting portion 12 and the engaging projecting portion 13 are press-contacted with each other so that they are plastically deformed and closely fitted to each other. Can be selected. If the protrusion 12 is a protrusion extending in the front-rear direction as in the present embodiment, the engaging recess of the receiving body and the fitting engagement accompanied by plastic deformation of the engaging recess of the engaging body are smoothly performed, and The contact area of the pressure contact portion can be increased, and wear of the pressure contact portion due to vibration during traveling of the vehicle can be suppressed.
