Description

[Detailed description of the invention] The present invention aims to solve the following problems.

(Industrial Application Field) This invention provides a rotatable connecting portion formed by bending the tip of a rod to a long connecting hole provided in a part of a lever in an automobile door lock. It is used to attach a rod to a car door lock.

(Prior Art) A conventional mounting device of this type has a connecting hole of a lever, as disclosed in FIGS. The cylindrical fitting part is divided into two fitting pieces, and locking claws are provided at the tips of the fitting pieces, and the two fitting pieces are elastically moved toward the center. After deforming and inserting the locking pawl into the long hole for connection, the fitting piece is restored and the locking pawl prevents the rod from being pulled out, and then the connecting portion of the rod is inserted into the hole of the fitting portion. Therefore, if the rod is twisted during transportation and a tilting force is applied to the mating piece in the direction along the cut groove, the mating piece will not be stopped by the locking pawl and will tilt greatly and its mating will be interrupted. There was a problem with the pieces being bent. In order to solve the above problem, it has also been proposed to fit a washer 30 into the fitting part as shown in Fig. 14, but in such a case, the number of parts is reduced by the washer. Along with this increase, the number of assembly steps also increased, and there was also the problem of forgetting to assemble the washer.
