Abstract:
1. A sensor extending in an axial direction and comprising: a sensor element; a tubular metallic shell radially surrounding the sensor element; and a tubular mounting member radially surrounding the metallic shell, being rotatable relative to the metallic shell, and having, at its radially outer surface, a threaded portion to be threadingly engaged with a mounting hole of a mount body; wherein the metallic shell has a body disposed radially inward of the mounting member, and a flange provided forward of the body and forward of the mounting member and projecting radially outward beyond a radially inner surface of the mounting member; as viewed on a section taken along the axial direction, a radially outer surface of the body of the metallic shell and a rearward-oriented surface of the flange of the metallic shell are connected by a slant surface formed such that the diameter of the slant surface increases toward the forward end thereof in the axial direction, and a forward-oriented surface of the mounting member and the radially inner surface of the mounting member meet at a corner; and when the threaded portion of the mounting member is threadingly engaged with the mounting hole of the mount body, a forward-oriented surface of the flange of the metallic shell comes into contact with a mounting surface of the mount body, and the corner of the mounting member comes into contact with the slant surface of the metallic shell.
