The swing lever 25 is swingable with a through hole 25b provided at the center thereof being pivotally supported by a support shaft 21b projecting from the machine frame 21, and projecting pieces 25c, 25c formed at both ends are openings of the main body 1. It is provided so as to project downward from a portion (not shown) so as to be detachable from the floor surface.
Therefore, as the eccentric cam 60 rotates, the swing lever 25 swings, and the projecting pieces 25c, 25c alternately press the floor surface, so that the main body 1 swings in the left-right direction.

When the head 2 is moved up and down by the third elevating lever 11 and is chewing, the first elevating lever 9 has the protrusion 9a engaged with the cam projection 70b provided on the rotary plate 70 on the second cam 63B surface. And it is in a state of moving up. When the front side of the head 2 is moved downward and the mouth is closed, the lever 4 for rotating the eye 3 and the first elevating lever 9 are moved upward when the first elevating lever 9 is moved upward. Then, the pupil portion 3b is arranged so as to face downward. Therefore, when the front side of the head 2 moves up and down to open and close the mouth, when the front side of the head 2 moves downward and closes the mouth, the lever 4 moves to the upper end of the first elevating lever 9. When the front end of the head 2 is moved upward and the mouth is opened, the lever 4 moves the first elevating lever. Since it is separated from the upper end of 9, the tip end portion is moved downward by the pulling spring 5, and the pupil portion 3b faces the front so that the eyes are open.
(See FIG. 4) The vertical movement of the pupil portion 3b is added as an auxiliary motion of the masticatory action together with the click sound generating mechanism.

In the mastication operation, the gear shaft 46 is separated from the end of the engaging projection 66 on the surface of the second cam 63B, slides in the leftward direction shown in FIG. 6 by the elastic force of the pressing spring 46a, and the pinion 48 moves to the gear. 5

Then, the arcuate rack 69 on the surface of the second cam 63A meshes with the pinion 78, and the rotating body 75 rotates. Rotation of the rotating body 75 causes the tongue piece 17 to move to the long hole 17 at the base end.
The pin 75a fitted in b makes a circular motion, and since the pin 14a is fitted in the elongated hole 17a in the middle part, the tip part projects outward from the opened mouth part to make an arc motion. It goes down in the mouth while performing. The tongue piece 17 performs this tongue licking operation for the number of rotations of the pinion 78, and then retracts into the mouth and stops. And the second lifting lever 1
The protruding piece 10a of 0 separates from the cam projection 71b on the surface of the second cam 63B, and the second elevating lever 10 moves downward to close the mouth.

When the tongue-licking operation is completed, the cam protrusion 70b provided on the rotary body 70 on the surface of the second cam 63B engages with the protrusion 9a of the first elevating lever 9 to move the first elevating lever 9 upward. The upper end of the first elevating lever 9 pulls the lever 4 into a spring 5
Against this, the push-up pupil part 3b faces downward and the eyes are closed. Then, the projection 72a of the electrically conductive contact piece 72 constituting the rotary switch is fitted into the notch 64 formed on the outer peripheral edge of the second cam 63, and the electrically conductive contact pieces 72, 7 are formed.
