[Mode of operation]
The operation mode of the seated exercise apparatus 1 having the above-described configuration is as follows.
The user first sits in a posture straddling the seat 3 and turns on the start switch using the operation panel unit 10.

Then, the electric motor 30 of the drive mechanism 17 rotates, rotates the worm wheel via the worm gear, and rotationally drives the rotary shaft 18.
Accordingly, the right cam member 33 and the left cam member 34 attached to the rotary shaft 18 rotate, and the left support arm 19A and the right support arm 19B try to rotate in the same direction. However, since the steady pin 43 provided at the lower part of the boss portions 37 and 48 is fitted in the steady groove 44 of the locking member 45, the accompanying rotation is restricted.
The cam surfaces 32A formed on the right cam member 33 and the left cam member 34 are inclined in the same direction with respect to the rotating shaft 18, and the steady pin 43 slides left and right along the steady groove 44. Since this is possible, as the rotary shaft 18 rotates, the left support arm 19A and the right support arm 19B move left and right in the same phase. That is, when both the first boss portion 41 and the third boss portion 49 move to the left side, both the second boss portion 42 and the fourth boss portion 50 move to the right side. When both the third boss portion 49 moves to the right side, both the second boss portion 42 and the fourth boss portion 50 move to the left side.

Since the left support arm 19A and the right support arm 19B perform such a movement, as shown in FIG. 5, the first support shaft 21 and the second support shaft 22 face each other in the left-right direction and maintain a parallel state. However, when one of the support shafts 21 and 22 moves to the right, the other support shafts 22 and 21 reciprocate so as to move to the left.
With this movement, a pair of left and right first support pins 60, 60 provided to face upward with respect to the first support shaft 21, and a direction to face upward with respect to the second support shaft 22. The pair of left and right second support pins 61, 61 move in opposite phases in the left-right direction. The first and second connecting members 62 and 63 into which the support pins 60 and 61 are inserted in a loosely fitted state also move in the left-right direction with opposite phases.

Therefore, the seat 3 connected to the first and second connecting members 62 and 63 so as to be rotatable about the vertical axis rotates and reciprocates in the left-right direction around the center in plan view.
Therefore, the user sitting on the seat 3 is given a movement that twists the waist and abdomen and is also given a movement that breaks the balance, so that the muscles of each part of the body and the sense of balance are strengthened. As a result, health promotion such as dieting can be achieved.
