LUBRICANT COMPOSITION, SEIZURE-PREVENTING AGENT, SENSOR AND SENSOR-ATTACHING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a lubricant composition applicable to a metallic component having possibility to be exposed to a high temperature of≥500°C without using a metal such as copper, aluminum and nickel, and boron nitride; and to provide a seizure-preventing agent using the composition, a sensor with the seizure-preventing agent applied thereto, and a sensor-attaching structure. SOLUTION: The lubricant composition contains a first solid lubricant comprising one or more of bismuth and a bismuth compound, and a lubricant base oil, or the lubricant base oil and a thickener, regulated so that the content A of the first solid lubricant and the content B of the lubricant base oil and the thickener may satisfy the relations: 15 mass%
