The handle cover 23 enters the sliding end receiving hole 222 from a position retracted by a predetermined amount from the contact peripheral edge of the cover 231 with the outer panel. A key cylinder support portion 232 having a shape that can be inserted is extended and formed. The key cylinder 13 is integrally attached to the key cylinder support portion 232, and the key insertion hole side of the key cylinder 13 is formed to face the key hole h of the cover 231. A release lever 25 is attached to the inner end of the key cylinder 13 and connected to a link system that functions to maintain the door lock by causing the door lock release operation of the latch 5 of the door lock mechanism 4 to idle. A locking control rod (not shown) is pin-coupled.

  The key cylinder support portion 232 is shaped so as to fit closely into the fitting chamber 223 of the base member 22. The fitting chamber 223 of the base member 22 is surrounded by the annular wall portion 224. In particular, the rear end side is formed as an inclined wall 224s. The key cylinder support portion 232 is formed as an inclined wall at an opposing portion that contacts the inner surface of the inclined wall 224s, and both the inclined walls are fastened by the fastening bolts 26 and integrated.

  Here, the fastening bolt 26 is disposed to be inclined with respect to the vehicle body longitudinal direction X, and a work hole 15 is formed at a site where the fastening bolt 26 contacts the bent peripheral edge 901 of the inner panel 9 on the extension of the center line L1. ing. Here, the work hole 15 is formed in such a size that a driver K as a tightening tool can be easily fitted from the direction along the center line L1.

  In order to assemble the door handle 12 of FIG. 1 to the outer panel 8, first, the base member 22 is overlapped with the back surface of the handle facing recess 17 of the outer panel 8, and then the pivot hole 212 of the pivot extension portion 211 of the lever member 21. Is fitted to a hinge protrusion 222 formed on the base member 22 to set the rotation center position O, and the hook portion 213 of the lever member 21 is pivotally supported on the base member 22 on the back side of the outer panel 8. Then, the key cylinder support portion 232 is fitted into the fitting chamber 223 through the sliding end through hole 19. Then, a screwdriver K, which is a tightening tool, is inserted from the outside of the working hole 15 in the bent peripheral edge portion 901, meshed with the fastening bolt 26, tightened with the fastening bolt 26, and fitted to the fitting chamber 223. Portions 232 can be joined together. Thereafter, the plug body 141 of the hole closing plug 14 is pushed into the work hole 15 and can be fitted in a state in which detachment is restricted. At this time, the buffer portion 11 formed integrally with the plug main body 141 via the extending portion 142 is attached so as to be superimposed on the back surface of the vertical sliding end 101 of the panel portion D.

  Thereafter, the connecting end of the bending lever 27 pivotally supported by the base member 22 is connected to the latch 5 of the door lock mechanism 4 via a control rod (not shown). Further, a locking control rod (not shown) is connected to the release lever 25 at the protruding end of the key cylinder 13. Furthermore, the attachment member is assembled to the other front door 1 to complete the assembly of the front door 1.

  Since the front door 1 and the rear door 2 adopt a door end overlapping structure, the vertical sliding end 101 of the front door 1 faces the vertical base end 201 of the rear door 2 with a predetermined gap tx in the front-rear direction X, A substantially continuous outer surface fd can be maintained. In addition, the front end overlapping edge 202 of the vertical base end 201 of the rear door 2 is arranged on the vehicle inner side through the gap ty in the door thickness direction Y with respect to the vertical sliding end 101 of the front door 1. For this reason, while making the outer surface fd of the front and rear doors 1 and 2 into a continuous surface, running resistance can be reduced.

  In particular, it is assumed that an overrun of the front door 1 occurs during the door closing operation due to poor installation adjustment of the front door 1 or deterioration over time. In this case, the vertical sliding end 101 of the front door 1 tries to come into contact with the front end overlapping edge 202 of the rear door 2 from the door thickness direction Y, but the meat disposed on the back surface of the vertical sliding end 101 of the front door 1. Since only the thick buffer portion 11 abuts against the front end overlapping edge 202 of the front door 1 and elastically deforms, overrun of the front door 1 is prevented. In addition, it is possible to reliably prevent the rear surface of the vertical sliding end 101 of the front door 1 from contacting the front end overlapping edge 202 of the rear door 2 and making noise or peeling the coating film on the door.

The buffer portion 11 here is supported by the gap T between the back surface of the longitudinal sliding end 101 of the front door 1 and the front end overlapping edge 202 of the rear door 2 without misalignment by the hole closing plug 14, and thus for a long period of time. The buffer function can be demonstrated with high durability.
In particular, the buffer portion 11 here is not manufactured as a single product, nor is a special mounting member used, so that it can be integrated (one component) without impairing the function of the hole closing plug 14. The increase in the number of parts can be suppressed, the installation work can be simplified, and the increase in cost can be prevented.

  In the above description, the hole closing plug 14 is described as being attached to the work hole 15 used in the fastening work of the fastening bolt 26 of the door handle. However, the work hole in the present invention is not limited to this. That is, it may be a work hole of an assembly member used for assembling the key cylinder when the key cylinder is mounted on the outer panel independently with respect to the door handle, and the door lock mechanism and a set of control rods connected thereto. The working holes required for finding may be used, and the present invention can be applied to the hole closing plugs for closing these working holes. In these cases, the same effect as the hole closing plug of FIG. 1 can be obtained.
