ROTATION SPEED SENSOR PROTECTING STRUCTURE FOR TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide the rotation speed sensor protection structure of a transmission to protect a rotation speed sensor without using a special protection cover. SOLUTION: A transmission is formed such that a rotation speed sensor 3 to detect the rotation speed of a rotor at the internal part of the transmission is mounted on a transmission case 1. A protection wall 2 approaching one side of the rotation speed sensor 3 is integrally formed on the outer surface of the transmission case 1 and an oil cooler tube 5 is fixed at least on the other side of the rotation speed sensor 3. The rotation speed sensor 3 is guarded by the protection wall 2 and the oil cooler tube 5 and interference of other part and a tool with the rotation speed sensor 3 is prevented from occurring.
