Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pulling device provided on a steel panel body used as a front panel of a drawer or an opening / closing door of a cabinet, and more particularly to driving a latch for opening / closing the panel body. The present invention relates to a pulling device having a function.

[0002]

2. Description of the Related Art Conventionally, there have been provided various kinds of pulling devices provided on a panel body used as a front plate of a drawer or an opening / closing door of a cabinet.

For example, as a pulling device provided on a steel drawer front plate, as disclosed in Japanese Utility Model Publication No. 60-23412, the front plate is composed of a front plate and a back plate, and the front plate is notched. A synthetic resin pull member is formed by cutting and forming a bearing part that pivotally supports a latch drive shaft that has an opening and a pull plate fixed to the back plate, and then welds a guide frame formed as a separate member. Is fitted to the notch opening of the front plate from the back side, the front plate is connected to the back plate, and the pull tab member is sandwiched between the front plate and the back plate. However, the front plate of this structure is complicated in processing of the steel plate and requires a welding process for fixing the guide frame of another member, resulting in high cost.
