Abstract (en)
[origin: JPH02112212A] PURPOSE: To form and arrange a sufficiently stable bearing for a drive shaft by extending rods in a lateral direction with respect to a lengthwise direction of an insulating cylindrical member, through the bearing and through the wall of the insulating cylindrical member with both rod ends, thus wedging slits at the both rod ends to the wall of the insulating cylindrical member. CONSTITUTION: A bearing bush 2, provided at the center of an insulating cylindrical member 1, is held by pipe rods 3 and 4 crossing each other. The rods are formed from a rolled insulating material. The rods 3 and 4 are inserted into holes 5 and 6 of the bearing bush 2 in different planes. Ends 7 and 8 of the rods 3 and 4 are inserted into corresponding holes, provided on the wall of the insulating cylindrical member 1. The ends 7 and 8 of the pipe rods 3 and 4 have slits 9 and driven wedges 11. Thus, the rod ends are fixed on the wall of the insulating cylindrical member 1. The wedges 11 are held by projections 13, so as not to slip and fall away from the wall.
