PURPOSE:To keep parts in an upright state easily and stable as well as to aim at improvements in assembling efficiency, by setting up a magnet at the backside to a parts supporting surface of an assembled work body, while setting both N and S poles to both sides of a longitudinal shaft of each magnetic material long-size part. CONSTITUTION:A permanent magnet 27 is set up at the side of a back surface 22 of a supporting surface 18 of a base body 14 as an assembled work body, and with both N and S poles of the permanent magnet 27, there can be making attraction operatable, which makes a long-form small coil spring 12 possible to be uprighted. With this constitution, this long-form small coil spring 13 is made holdable in a state of being uprighted so easily and stably to the supporting surface 18 without being turned over, whereby improvements in assembling efficiency in the small coil spring 13 are promotable. Accordingly, automation for assembling of a pushbutton switch for automatically feeding the small coil spring 13, etc., is well promotable so that trouble and time are reduced as compared with the case that setting operation of the small coil spring 13 is carried out with tweezers or the like. |
