A swing bed (1) according to an embodiment is provided with: a seat body (2); a base (3); a shaft member (12); plungers (13, 14) fixed to the shaft member (12); a solenoid (9) that generates a magnetic field that attracts the plungers (13, 14) in the swinging direction; a swing control circuit (7) for controlling the swing operation of the seat body (2) by exciting the solenoid (9) at a predetermined timing; and a side wall part (11) disposed close to the solenoid (9) on the outer side in the swing direction of the solenoid (9) so as to enhance the magnetic field generated by the solenoid (9). The solenoid (9) is provided with a through hole (91a) extending in the swinging direction. A through hole (11a) communicating with the through hole (91a) is formed in the side wall part (11). The shaft member (12) is inserted through the through hole (91a) and the through hole (11a). The inner diameter of the through hole (11a) is equal to or less than the inner diameter (91a) of the through hole. 一实施方式的摇床(1)具备：座椅主体(2)
