Abstract
In a circular cross section obtained by cutting a protector along a plane which is orthogonal to an axial direction and passes through gas introduction holes, the gas introduction holes are arranged asymmetrically in the circumferential direction of a circumferential wall of the protector. When the circular cross section is bisected into first and second divisional regions by a straight line which passes through the center of the circular cross section and does not pass through any gas introduction holes, the total opening area of gas introduction holes located in the first divisional region is smaller than the total opening area of gas introduction holes located in the second divisional region.
