Title:
SCREW FIXING DEVICE AND METHOD OF MANUFACTURING SCREW FIXING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/007593
Kind Code:
A1
Abstract:
A screw fixing device (1) has a flange part (13) capable of being fixed to a flat plate
(body frame (50)) by staking (45) of the flange part to a hole (51) formed in the
flat plate (body frame (50)), and also has a circular tube part (10) contiguous to
the flange part (13) and having a space (15) in it. One turn of a screw groove (20) is
formed by press working in that top face (11) of the circular tube part (10) that closes
the tube part on the opposite side of the flange part. Thus, a series of manufacturing steps
including the step of forming the screw groove can be performed by press working.
The construction enables the series of steps, including the step of forming the
screw groove, for manufacturing the screw fixing device to be performed by press
working. This in turn prevents a worker from forgetting screw thread cutting
to provide a product definitely provided with a screw thread.
