Publication number: 20150083655Abstract: Provided is an oil deterioration prevention device with which the trapping effect with respect to oil deteriorated components can be improved and with which the oil passage resistance can be reduced, thereby suppressing a rise in pressure loss. This oil deterioration prevention device is equipped with a filter unit equipped with a filter material that filters oil; and a deterioration prevention unit equipped with a powdery deterioration suppressing agent that suppresses oil deterioration. The deterioration prevention unit contains a mesoporous inorganic material, and of the oil fed from an oil storage unit, the oil filtered by the filter unit is fed to parts which are to be lubricated, and the oil in which deterioration has been suppressed by the deterioration prevention unit is returned to the oil storage unit or is fed to the parts to be lubricated.Type: ApplicationFiled: April 30, 2013Publication date: March 26, 2015Applicants: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHOInventors: Hideto Morishita, Yasuhiro Saito, Ippei Fukutomi, Motoichi Murakami, Katsuichi Miyasaka, Yasuhiro Ohmiya, Hiroshi Moritani, Mamoru Tohyama, Narihito Tatsuda
