Abstract:
An instrument drive device configured in such a manner that a case body does not receive a load for press-fitting a pointer into a pointer shaft and that liquid, such as a lubricant, within the case body does not leak therefrom.
An instrument drive device (1) comprises; a case body (12) provided with a first bearing section (13) and a second bearing section (14) which are through sections; a pointer shaft (6) pivotably supported by the first bearing section (13) and the second bearing section (14) and having a part which protrudes to the outside from the case body (12) and to which a pointer is mounted. The instrument drive device (1) is also provided with a bearing body (16) press-fitted into and held by the second bearing section (14) and restricting the movement of the pointer shaft (6) in the axial direction. The second bearing section (14) is provided with a shaft support section (14a) for pivotably supporting the pointer shaft (6), and also with a holding section (14b) into which the bearing body (16) is press-fitted and held. The diameter of the holding section (14b) is set to be smaller than the diameter of the shaft support section (14a).
