PROBLEM TO BE SOLVED: To provide an attaching structure for a movement for a measuring instrument, capable of restraining dust from infiltrating the inside of the measuring instrument and make the indication accuracy of a pointer improved, and capable of making the assemblability satisfactory. SOLUTION: Locking arm parts 14, 14 are inserted from a reverse face side 4a into a pair of locking holes 24b, 24b formed opened in a circuit board 4 for the measuring instrument, locking claws 15, 15 are locked therein in peripheral edges of the locking holes 24b, 24b, and a casing member 13 is attached thereby to the reverse face side 4a of the circuit board 4 for the measuring instrument. A pair of left and right protruding parts 14f, 14f is projected respectively from one part in the vicinity of the locking claws 15, 15 on inner faces 14c, 14c positioned within the locking holes 24b, 24b toward sideway, in the locking arm parts 14, 14. The protrusion parts 14f, 14f are constituted to abut against the opening inner circumferential edge of the locking holes 24b, 24b, under a condition, where the casing member 13 is attached to the reverse face side 4a of the circuit board 4 for the measuring instrument.
