Title:
MOTOR DEVICE AND POINTER-TYPE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/110642
Kind Code:
A1
Abstract:
Proposed are a motor device in which vibrations in a stator core can be suppressed , and a pointer-type display device. In the case of this motor device, tip parts 230 of first protrusion sections 23, which hold a stator core 60 from inside of a first case 21 in the direction of a rotational center axis line LO in conjunction with a second case 22, are tapered toward the stator core 60. Also, tip parts 240 of second protrusion sections 24, which hold the stator core 60 from inside of the second case 22 in the direction of the rotational center axis line LO in conjunction with the first case 21, are tapered toward the stator core 60. Thus, when the protruding lengths of the first protrusion sections 23 and the second protrusion sections 24 are set somewhat long in advance, the first protrusion sections 23 and the second protrusion sections 24 hold the stator core 60 in a state in which the tip parts 230, 240 are crushed. In this state, when viewed from the axis line direction of a rotor, the first protrusion sections 23 and the second protrusion sections 24 overlap with each other.
