It is an energy-saving part letting the lubricant reduces friction and the abrasion of the contact surface for a machine, and a machine become high efficiency. However, environmental pollution by the outbreak of carbon dioxide at the time of the destruction by fire disposal or the toxic substance and influence on human body are concerned a lot about with a lubricant of mineral oil. Therefore I paid attention to the vegetable oil as the substitute of mineral oil. From a past study, as for the sesame oil, deterioration was slower than mineral oil among several kinds of vegetable oil. I paid attention to this sign and am intended to inspect possibility of the vegetable oil and perform a breakdown test of the new grease which assumed sesame oil basis oil. Therefore I design the breakdown test device from the beginning using 3DCAD and I examine it in a more severe state and evaluate grease. I could confirm maintenance of the grease performance for a long time, and, in a normal temperature examination, it followed that I could find utility. However, solidification of the grease by the oxidative degradation happened by the high temperature examination, and a weak characteristic was seen in heat. Therefore I inspect an antioxidant with the ability for adaptation in sesame oil now and finally aim at the development of the environmental harmony type grease with the utility.
