PROBLEM TO BE SOLVED: To reduce the thickness of a cap type case by arranging only a single core part in the axial direction along the inside wall of the cap type case and to reduce a diameter and weight by forming a recess part on the circumferential face. SOLUTION: In this speed detector for the vehicle, only a single core part 5 of a non-power source type sensor 4 is arranged in the axial direction 7 along the inside wall 3 of the cap-type case 1, and the recess part 41 is formed on the circumferential face for reducing thickness, a diameter, and weight.
