The present invention is an analog display type timepiece, in which protrusions are provided on the main plate to connect with the stator on the outer periphery of two screw pins buried in the main plate, so as to reduce the effect of warping of the stator on the main plate and prevent deterioration in motor performance. This is what I did.
従来のステータの支持構造を第２図ａ，ｂを用

A conventional stator support structure will be explained using FIGS. 2a and 2b.

テータ１を地板３が支持していた。 1 is the stator. 2 is the magnetic core. 3 is the main plate. 4 is a screw. 5 is the gear train holder. 6 is the rotor. 7 is the contact surface between the main plate and the stator. 8 is a screw pin. The aforementioned base plate 3 and stator 1 were fastened together with screws 4 to bring the contact surfaces of the base plate 3 and stator 1 into close contact over a wide range, so that the stator 1 was supported by the base plate 3.

However, in the above-mentioned conventional technology, especially when the base plate is a plastic molded product, the amount of warpage of the base plate 3 increases due to processing capacity, and in FIG. 2a, the base plate 3 and the stator 1 are in close contact over a wide range, Furthermore, the screws 4 are tightened and the stator 1 is pressed against the base plate 3, causing the stator 1 to deform into the same shape as the warpage of the base plate 3. After deformation, internal strain is generated in the stator 1, deteriorating the magnetic properties of the stator 1. Ta. As a result, motor performance was significantly degraded.

In order to solve the above-mentioned problems, the stator support structure of the present invention is designed such that the stator is attached to the outer periphery of two screw pins buried in the base plate, where distortion due to the base plate formation can be ignored and deterioration of motor performance can be suppressed. It is characterized by having a protrusion that connects with the main plate buried in the base plate.

る構造となつている。 By limiting the contact surface 7 (shaded area) between the main plate and the stator to the area around the screw pin 8, and minimizing the continuous joining area between the main plate 3 and the stator 1, the contact between the stator 1 and the main plate 3 is reduced. The contact area of the stator 1 is small, and there is a gap between the stator 1 and the main plate 3 except for the contact area, so that the warpage of the main plate does not directly affect the stator 1, and the deformation of the stator 1 can be suppressed. There is.

As described above, according to the present invention, the base plate is provided with a protrusion on the stator side at the outer periphery of the buried screw pin, the joint surface on the upper surface of the protrusion is connected to the stator, and the stator other than the joint surface is By creating a configuration with a space between the stator and the main plate, even if a plastic main plate is used, which tends to warp a lot due to machining efficiency, the warp will not directly affect the stator due to the space. Therefore, the stator is prevented from being deformed, causing internal strain in the stator, and deteriorating the magnetic characteristics, thereby providing a stator support structure with high reliability in motor performance.
