Patent number: 8932172Abstract: A differential includes a pinion shaft holder, a differential case, a first side gear, a second side gear, a first spring and a second spring. The differential case includes a first side boss portion and a second side boss portion. The first spring is interposed between the first side boss portion and the first side gear. The second spring is interposed between the second side boss portion and the second side gear. A recessed portion is provided on the pinion shaft holder and is configured to avoid interference with an auxiliary tool. The auxiliary tool maintains one of the first spring and the second spring in the compressed state.Type: GrantFiled: February 1, 2013Date of Patent: January 13, 2015Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin AW Co., Ltd.Inventors: Koichi Tanaka, Tatsuya Kawamura, Hiroya Mizuta, Koichi Nakamura, Rikiya Kubo, Yoshihiko Sasaki

Patent number: 8508090Abstract: PROBLEM TO BE SOLVED: A lubrication structure of a power transmission apparatus is provided with a lubricating liquid transport pipe for cooling a rotating electrical machine used to allow a lubricated member positioned axially outwardly of the rotating electrical machine to be lubricated in the axial direction. SOLUTION: A lubrication structure comprises an oil pipe 44 having discharge nozzles 44a, 44c positioned vertically above coil ends 20a, 20b and discharge nozzles 44d, 44e axially outwardly of the discharge nozzle 44c in juxtaposed relationship with each other at the other axial end portion of the oil pipe 44, and a guide member 22 radially extending between the discharge nozzles 44d, 44e in the axial direction of a motor M and having a radially inner peripheral portion covering bearings 24, 42. The guide member 22 has a guide rib extending axially outwardly of a flange portion 22a to guide the oil discharged from the discharge nozzle 44e in the axial direction.Type: GrantFiled: February 19, 2010Date of Patent: August 13, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koichi Tanaka, Terasu Harashima, Rikiya Kubo
