PROBLEM TO BE SOLVED: To obtain a technology which can effectively reduce drag torque during the execution of an electric traveling mode.SOLUTION: A friction engagement device CL comprises: at least a single piece of a first friction plate 31B having friction abutment faces on which friction materials 3 are placed at both sides in an axial direction L; a plurality of pieces of second friction plates 31A which have friction abutment faces on which the friction materials 3 are not placed at both sides, and are arranged so as to sandwich the first friction plate 31B from both the sides in the axial direction L; a first support member 40 which rotates integrally with the first friction plate 31B; and a second support member 90 which rotates integrally with the second friction plate 31A. Grooves extending to a radial direction R are formed at friction abutment faces at both sides of the first friction plate 31B in the axial direction L. The first support member 40 is drive-connected to a rotating electric machine MG, and the second support member 90 is drive-connected to an input shaft.SELECTED DRAWING: Figure 4
【課題】電動走行モードの実行中における引き摺りトルクを効果的に低減することが可能な技術を実現する。【解決手段】摩擦係合装置CLは、摩擦材3が設けられた摩擦当接面を軸方向Lの両側に有する少なくとも1枚の第一摩擦板31Bと、摩擦材3が設けられていない摩擦当接面を軸方向Lの両側に有すると共に第一摩擦板31Bを軸方向Lの両側から挟むように配置される複数枚の第二摩擦板31Aと、第一摩擦板31Bと一体回転する第一支持部材40と、第二摩擦板31Aと一体回転する第二支持部材90とを備える。第一摩擦板31Bの軸方向Lの両側の摩擦当接面に、径方向Rに延びる溝部が形成されている。第一支持部材40が、回転電機MGに駆動連結されると共に、第二支持部材90が、入力部材に駆動連結される。【選択図】図4
