PROBLEM TO BE SOLVED: To secure sealing performance while suppressing enlargement of a gas sensor.SOLUTION: A cover part 10 comprises a cover 100 and a metal member 110. The cover 100 comprises a resin outer cylinder 101 which is made of a resin and has a collar part 102 formed in a projection shape to the inside in a radial direction. The resin outer cylinder 101 and the metal member 110 are arranged so that a tip end surface 106 of the resin outer cylinder 101 is in contact with a rear end surface 116 of a flange part 112, and are fixed by caulking a bent part 115 to a rear end 107 of the collar part 102 through a packing 118. Since the collar part 102 is formed in a projection shape to the inside in the radial direction, on the inside of the resin outer cylinder 101, the metal member 110 can be caulked and fixed from the inside in the radial direction toward the outside in the radial direction, to the collar part 102, and the resin outer cylinder 101 and the metal member 110 are fixed while suppressing enlargement of a gas sensor 200. |
