Temperature sensor of automobile brake-oil

摘要

PURPOSE: A temperature sensor of brake oil for a vehicle is provided to prevent disconnection of a reed wire when the air of an oil tank is exhausted. CONSTITUTION: A temperature sensor of brake oil for a vehicle comprises a body(22) inserted in an air exhaust port of an oil tank filled with brake oil, to detect the temperature of the brake oil; a threaded part(24) formed to the periphery of the body, to combine the body to the air exhaust port of the oil tank; and an air exhaust groove(26) formed to a portion of the threaded part, with predetermined depth. Air of the oil tank is exhausted through the air exhaust groove. The air exhaust groove is deeper than the threaded part.
