<P>PROBLEM TO BE SOLVED: To allow a sealing member for closing an opening end of a machined hole to be prevented from coming off reliably with a simple structure using an auxiliary machine approaching a pump casing, even if the machined hole opened to an outer end surface of the pump casing for forming an intake oil path and/or a discharge oil path is drilled in the pump casing, in an oil pump structure. <P>SOLUTION: For forming at least either of the intake oil path Li and the discharge oil path Lo, the machine hole H to be opened to the outer end surface of the pump casing C is drilled in the pump casing C. In the machined hole H, a sealing member P for closing an outer opening end Ha of the machined hole is liquid-tightly filled. On an outer end of the sealing member P, an outer end surface Bmf of the auxiliary machine B to be closely arranged to the pump casing C and connected to a transmission housing M is opposed. With the auxiliary machine B, the sealing member P is prevented from coming off from the machined hole H. <P>COPYRIGHT: (C)2012,JPO&INPIT |
