Document Type and Number:
Japanese Patent JPS5740115
Kind Code:
A
Abstract:
PURPOSE:To enable assembly in one direction at the time of securing, by placing a screw, which has a head of larger diameter than a threaded part, so that the screw extends through a secured hollow shaft and by thread-engaging the end of the screw in a frame which is provided with a recess for fitting the secured shaft and with female threads for engaging the screw. CONSTITUTION:A screw 3, which has at one end a head 3a of larger diameter than a threaded part and has at said end a flange 3b of larger diameter of a secured hollow shaft 2, is placed so that the screw 3 extends through the shaft 2. The end of the screw 3 is thread-secured in a frame 1 which is provided with a recess 6 in which the secured shaft 2 is fitted and with female threads 7 with which the screw 3 is engaged. According to this constitution, assembly at the time of securing of the shaft 2 is facilitated and the accuracy of the securing is kept high. Since the dimensional accuracy of the shaft 2 needs to be made high only as to the outside diameter, the shaft 2 is made economic.
