<P>PROBLEM TO BE SOLVED: To obtain a bearing mechanism for receiving a gear thrust force by a compact power transmission mechanism dispensing with a part for fixing the axial direction of a steel ball or a pressurization mechanism and a part for fixing the radial direction. <P>SOLUTION: In the power transmission mechanism, the thrust force in the gear axial direction generated by an input gear shaft 1 in which a helical gear is cut and a helical gear 2 meshing with each other is supported by a thrust force support plate 14 in a solid cylindrical shape of which the outer diameter face is fixed in the gear case 10 of a casing, and the steel ball 13 which is provided on the shaft end face of a power transmission shaft and is installed in a fixed hole 12 in a shape that drop off is not caused even if the power transmission shaft moves to either of the positive and negative direction of the shaft. <P>COPYRIGHT: (C)2013,JPO&INPIT |
