生ずる原因ともなる。(Prior Art) As a conventional method for attaching a torsion pendulum device, for example, the upper end of a hanging rod of a pendulum is fixedly connected to the lower end of a support member held within an exterior case by screwing. (Problem to be solved by the invention) However, according to this mounting method, if the place where the clock is placed is inclined, the pendulum will be supported at an angle with respect to the pendulum device, resulting in the pendulum being unstable. It operates stably and may cause shaft loss of the pendulum.

のである。(Means for Solving the Problems) The present invention provides a connection in which one of the ends of a torsion pendulum device and the end of a support that supports the end of the pendulum has a spherical surface. The other end is a gripping portion that grips the spherical portion of the connecting portion to enable spherical movement, and the connecting portion and the gripping portion are of a so-called universal joint type.

に取付けてある。 In FIG. 1, the torsion pendulum device 1 is provided with an ornament 12 that reciprocates downwardly around a torsion drive block 11, and has a hanging rod 13 erected above. The decoration 12 has a decoration shaft 14 hanging down from the case of the torsion drive block 11, and a swinging ball 15 is provided horizontally at the lower end. The ornamental shaft 14 rotates in conjunction with the driving force of a drive mechanism housed in the case of the block 11, and the swinging ball 15 can twist and rotate with this rotation. At the upper end of the hanging rod 13, a sphere 16 serving as a connecting portion is provided integrally with the mounting shaft. This sphere is attached to the lower end of the support 2.

The inner surface of each grip part 22 that comes into contact with the handle 6 is provided with an uneven surface to increase frictional resistance, thereby preventing the torsion drive block 11 from rotating due to the inertia of the decoration 12.

揺動可能である。 The method of installing the torsion pendulum device 1 is as follows:
When the sphere is pushed up in the direction of the arrow in the figure and pushed into the grip part at the lower end of the support body 2 as shown by the chain line, the elastic arm part 21 is elastically deformed outward due to this pushing.
As shown by the solid line in FIG. 2, the sphere and the grip are connected, and in the connected state, the pendulum can swing around the sphere.

Further, the connecting part does not need to be a sphere as long as it has the function of a universal joint in relation to the gripping part of the support, and it is sufficient if at least both side surfaces are spherical.

Stable rotation is possible and there is no problem of shaft loss.
