A plurality of horizontal frames 5b are fixed between the 5a, and the longitudinal frame 5a and the horizontal frame 5b form a swing table 5 for a baby. A string or chain may be used instead of the hanging rod 4. The upper end of the string or chain may be locked to the longitudinal frame 1a, or may be locked to both ends or the center of the horizontal frame 1b.

Of the plurality of horizontal frames 3b fixed between the longitudinal frames 3a, 3a of the lower frame 3, the rod 8 is attached to the tip of the rotary arm 7 which is rotated by the rotary shaft of the motor 6 fixed to the intermediate horizontal frame 3b. One of the lateral frames 5 of the rocking base 5 is pivoted at one end and the other end is at the other end.
pivot to b.

The rotary arm 7 may be fixed at one end thereof directly to the rotary shaft of the motor 6 or to a gear 9 which is interlocked with the rotary shaft. When the rotating arm 7 is directly rotated by the rotating shaft of the motor 6, the rotation speed can be adjusted by using a transmission. When the rotating arm 7 is rotated by a gear that interlocks with the rotating shaft of the motor 6, one or a plurality of gears are used and the diameter of the gear is selected so as to obtain a preferable rotation speed.

The rocking base 5 rocks as follows.
When the motor 6 is rotated, the rotating arm 7 is rotated, and the rod body 8 pivotally stopped by the rotation arm 7 is pushed. In FIG. 2, the tip of the rod body 8 pushes the horizontal frame 5b of the rocking base 5 to the right to rotate it. When the arm 7 becomes parallel to the frame 5a, the horizontal frame 5b moves to the rightmost, and when the rotary arm 7 further rotates, the rotary arm 7b is rotated.
Pulls the rod body 8 and then pushes it in the opposite direction, to the left in FIG. 2, so that the rocking base 5 also sequentially shifts to the left, and the rotary arm 7 moves in the direction opposite to the direction shown in FIG. 5
When it becomes parallel to a, the swing base 5 moves to the leftmost. Further, since the rotary arm 7 rotates, the swing base 5 is next.
Reverses and shifts to the right again. The rocking table 5 swings most to the left and right ends, and swings the lowest in the center. The rocking table 5 repeats the above-mentioned left-right shift.

The swing speed of the swing table 5 is 0 at both left and right ends of the swing, and becomes faster toward the center. The change in speed is shown in Table 1.

[0026]

[Table 1]

The oscillating table 5 may have a lattice shape, a plate such as a plate may be stretched to be flat, or a single plate may be used.
