PROBLEM TO BE SOLVED: To securely hold, in cylindrical support hole portions, a support shaft for turnably supporting the rotor of an electric motor built in a resin casing of the movement for a measuring instrument, and a support shaft for turnably supporting an intermediate gear of a reduction gear train, for transmitting the rotation of the electric motor to a pointer shaft after reduction. SOLUTION: On a casing member 10a, the support hole portions 12b and 12c are formed through an upper wall 12 so as to support base portions 41 and 72 of the support shafts 40a and 70c respectively, and the support hole portions 12b and 12c are each provided with an inside diameter of a drawn end side axial hollow portion J2 larger than that of the other axial hollow portion J2, J4, excluding the portion.
