FIELD OF THE INVENTION The present invention relates to a door handle, in particular for motor vehicles.

2. Description of the Related Art A door handle for an automobile has a bracket fixed to a door panel of the automobile and a handle body pivotally attached to the bracket. For example, as disclosed in Japanese Utility Model Publication No. 62-21635, a bracket that also serves as an escutcheon is provided with a pair of rectangular holes and a pair of arm portions adjacent to the rectangular holes on the back surface of the bracket. A circular through hole is provided at the tip of each arm. Further, the bracket is formed with a circular hole into which the key cylinder of the lock device is mounted, if necessary.

Further, a pair of arm portions are integrally formed on the handle body, and a through hole is formed adjacent to the tip of each arm portion.
One of the handle bodies has a connecting hole in the arm,
A rod which is operatively connected to a lock device provided in the door is connected to the connecting hole through a connector. Pins are attached to the through holes of the bracket and the arm portion of the handle body so as not to fall off, and the handle body is rotatably supported with respect to the bracket. Two adjacent arm portions of the handle body and the bracket are pivotally attached by pins. The handle body is pressed by the spring in a direction toward the door panel.

In the above structure, when the handle body is pulled up by hand, the handle body rotates outward around the pin, the rod connected to the arm part of the handle body moves downward, and the lock device is activated to operate the door. Can be opened. When the hand is released from the handle body, the handle body is automatically rotated by the spring toward the door panel and returned to the original position.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the case where a pin is permanently attached to a through hole of an arm portion of a bracket and a handle main body, conventionally, the pin is knurled to penetrate an arm portion having an inner diameter slightly smaller than the diameter of the pin. The pin was pressed into the hole. Therefore, a step of knurling the pin and a step of press-fitting into the hole of the arm portion are required. These steps require processing jigs,
When the two pins are press-fitted into the holes of the arm, the manufacturing time of the automobile door handle is increased. Further, even if the pin is press-fitted into the hole of the arm portion, there is a risk that the pin may come off due to a machining accuracy error, vibration of the automobile, or the like.

Therefore, an object of the present invention is to provide an automobile door handle that has a small number of parts and is easy to manufacture.
