As shown in FIG. 2, the rotational force generating portion 10 includes the spindle-shaped rotating body 11, the transmission gear 13, and the starting shaft 1 for fixing and supporting the rotating body 11 and the transmission gear 13.
It consists of 2. The rotating body 11 has a fan shape and is rotated with the starting shaft 12 by receiving a centrifugal force when the container body 1 shown in FIG. Generates rotational force in two directions. That is, rotation in the forward direction or the reverse direction is continuously performed depending on how to swing the container body 1. The transmission gear 13 transmits the rotational force to the rotation direction adjusting unit 20. The shape of the rotating body 11 may be a fan shape or a pendulum shape in which a disk is provided at the tip of a flat plate. That is, any shape may be used as long as it is easily rotated about the starting shaft 12 by centrifugal force. The transmission gear 13 can be replaced by providing teeth on the side surface of the starting shaft 12.

The gears 23 are fixedly attached to the linkage shaft 25 in association with each other. As shown in FIG. 2, each of the parent gears 22 of the parent-child gears 21a and 21b has a tooth surface which is uneven in the axial direction, and applies a rotational force in the normal and reverse directions generated in the rotational force generating section 10 to each other. The transmission gears 13 for transmission are in mesh with each other.

The pawl gear 24 is formed to have an elastic force, meshes with the daughter gear 23 only when the daughter gear 23 rotates in one specific direction, and the daughter gear 23 rotates in the other direction. When it does, it elastically bends to make a sliding contact with the child gear 23. As a result, each of the pawl gears 24 only rotates in a specific one direction out of the rotations in the forward and reverse directions transmitted from the parent and child gears 22.
The transmission gear 26, which is attached to a substantially intermediate portion of the linkage shaft 25, transmits the rotation in one direction to the outside. In this way, each of the gear group mechanisms transmits only the rotation in one of the forward and reverse two-direction rotations to the linkage shaft 25 to adjust the rotation in the two directions into the one-direction rotation.
