Abstract
A sensor includes: a tubular needle member that includes a side wall and defines a hollow portion; and a linear detection member located in the hollow portion. The side wall of the needle member includes a thick portion that is thicker than another portion of the side wall in a cross-section of the needle member, and wherein the thick portion protrudes toward the hollow portion.
Claims10
A sensor comprising:
- a tubular needle member that comprises a side wall and defines a hollow portion;
- and
- a linear detection member located in and immovably fixed in the hollow portion;
- wherein:
- the side wall of the needle member comprises a thick portion that is thicker than another portion of the side wall in a cross-section of the needle member, and wherein the thick portion protrudes toward the hollow portion;
- the thick portion comprises a thick portion inner wall, and the thick portion inner wall comprises a receiving surface that receives the detection member;
- the thick portion inner wall further comprises:
- a top portion, a first side portion that is continuous from the top portion to a first side of the needle member in a circumferential direction and in which a wall thickness of the needle member gradually decreases from the top portion toward the first side of the needle member in the circumferential direction, and
- a second side portion that is continuous from the top portion to a second side of the needle member in the circumferential direction and in which the wall thickness of the needle member gradually decreases from the top portion toward the second side of the needle member in the circumferential direction;
- and
- the receiving surface is a surface of at least one of the first side portion or the second side portion.
