PURPOSE:To polish the through-field at the shaft bearing section efficiently, in a bearing structure where the shaft bearings are located at the opposite has, by equalizing the basic diameter of shaft while differentiating the substantial gaps between the shaft and said bearings. CONSTITUTION:A plain bearing 2 and an oil seal 3 are contained in a housing 1. A portion of fixing table 5 of a weight for leading a governor will bite into a groove having a knurling in the shaft 4 while the weight support 7 is secured to the weight fixing table 5. Furthermore, the outercircumference of the ball bearing 8 is fixed through a stopper board 9 and a screw 10 to the housing 1 while the ball bearing 8 is pressure inserted over plural projections 13 machined through rolling upon polishing of through-field. The shaft fitting section of the weight fixing table 5 is made similar with the basic circle of the shaft 4 and the fitting section of plain bearing 2. |
