<P>PROBLEM TO BE SOLVED: To provide a structure of a lubricating oil inlet capable of preventing loosening of a cap and improving fastening of the cap. <P>SOLUTION: A flat section (20) is formed in an end section (19) of a screw groove (12) in a shaft section (11) of a cap (9). The end section (19) is positioned on a gripping section (10) side of the cap (9) in an axial direction of the shaft section (11). The flat section (20) bends from an angled section (13) that comes into contact with the lower section of a projecting section (16) of an inlet (7) and extends in a direction perpendicular to an axial line (C) of the shaft section (11). The length (L1) of the flat section (20) in the direction perpendicular to the axial line (C) of the shaft section (11) is set to be longer than the length (L2) of the projecting section (16). <P>COPYRIGHT: (C)2012,JPO&INPIT |
