PROBLEM TO BE SOLVED: To improve assembly operativity at the time of assembling movements on a circuit board. SOLUTION: A printed circuit board 15 is mounted on a rear of a measuring instrument case 13 of a vehicle measuring instrument, and a movement driving to rotate a pointer on a dial 21 is assembled from a surface side. A through hole 47 has been formed on the measuring instrument case 13 corresponding to the movement. The through hole 47 is equipped with three guide walls 49 at a predetermined distance along a circumferential direction. The guide wall 49 includes a positioning part 49a having a diameter approximately the same as an outer diameter of the movement and a taper 49b whose inner diameter on an insertion side is formed to be large.
