[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an easy closer device for an automobile door.

[0003]

2. Description of the Related Art A door opening for an automobile and the periphery of the door are sealed with a weather strip.
In order to improve the sealing property, it is desirable that the weather strip has a large pressure contact force. However, when the pressure contact force is increased, a large operation force is required especially when the door is closed, in a large door such as a slide door.

Therefore, an easy-closer device for a door is used, which includes a fixing member fixed to an automobile body, a striker projecting from an opening edge panel of an automobile door and engaging with a latch, and a fixing member. It has a movable part of the striker guided movably in and out of the door opening, and a drive means for moving the striker in and out of the door opening. Detects that the latch is engaged with the striker in the outer position when the door is open, and drives the striker to pull inward.If you close it with a light touch, the door will be automatically pulled in afterwards and it will be high. A sealing force can be obtained.

[0005]

However, the above-mentioned device has a structure in which a resin piece having a U-shaped cross section having good slidability is fitted on the sliding surface between the movable portion and the fixed member of the striker. Therefore, a gap may occur between the movable part of the striker and the resin piece and between the fixed member and the resin piece, which causes play between the movable part of the striker and the fixed member.
As a result, the striker rattles in the vertical direction of the vehicle.

Therefore, the present invention has as its technical problem the solution of the above problems.

[0007]

[Constitution of the invention]

[0008]

The technical means taken in the present invention to solve the above technical problems is to provide an internal structure between one of the movable part and the fixed member of the striker and the other member. A substantially concave guide groove provided so as to form a space, a slide block arranged in the internal space so as to slide relative to the other member, and a slide block attached to the inside and outside directions of the door opening. A biasing elastic means, and an inclination that spreads in the direction opposite to the biasing direction of the elastic means on one of the inner bottom surface of the guide groove and the side surface of the other member facing the internal space or on one side surface of the slide block. A surface is formed, one side surface of the slide block is brought into contact with the one surface by the urging force of the elastic means, and the other side surface of the slide block is either the inner bottom surface of the guide groove or the side surface facing the inner space of the other member. Or other side It is to be abutted.

[0009]

According to the above technical means, the slide block is interposed between the movable portion of the striker and the fixed member, and is slid between the slide block and any member. The slide block moves in a direction to eliminate the gap on the sliding surface by the urging force inward and outward of the door opening. As a result, the gap on the sliding surface of the slide block is reliably absorbed, which prevents the striker from rattling in the vertical direction of the vehicle.
