  • Patent number: 10316956
    Abstract: A flange portion of a reservoir plate is provided with a holding portion that holds a working oil supply pipe disposed on a converter housing and that is composed of an overhanging portion formed so as to overhang toward the converter housing and a dented portion formed in the overhanging portion along the working oil supply pipe. Consequently, it is possible to reduce the number of components and achieve better assembly compared to a configuration in which another member such as a clamp member is used to hold the working oil supply pipe. Since the holding portion is formed in a complex shape from the overhanging portion and the dented portion with recesses and projections, moreover, the strength of the holding portion against bending etc. can be enhanced.
