問題点がある。2. Description of the Related Art As a conventional seal structure for preventing rainwater from entering a door lock body, a band-shaped seal member made of a soft synthetic resin material such as rubber is provided on an upper side surface of a resin body of the door lock. Although there is an adhesive stuck with an adhesive or the like, the seal member may be peeled off from the resin body during the assembly process of the door lock, and there is a problem that the workability is reduced.

For example, there is one disclosed in Japanese Utility Model Laid-Open No. 56-84658. That is, over the upper and side portions of the side surface of the resin body of the door lock mounted on the door panel,
An object of the present invention is to improve the workability by continuously and integrally forming an elastically deformable fin piece having an appropriate width which is in close contact with a door panel.

い問題点がある。However, when the fin pieces are formed integrally with the resin body as described above,
Although the workability is improved, the resin body is generally subjected to a large load, so the resilience of the fin pieces is insufficient and the fin pieces are cracked due to the fact that the resin body is molded from a strong and hard synthetic resin material. However, it is difficult to completely adhere to the door panel, and there is a problem that it is impossible to reliably prevent rainwater from entering.
