In the massage device according to the second aspect, the first and second driving pulleys are provided on one rotating shaft, and both ends of the transmission belt are wound around the first and second driving pulleys in opposite directions. Unlike the configuration in which the first and second driving pulleys are separately mounted on two shafts, the number of parts is small and the weight can be reduced. . In addition, at least one engaging portion is provided on one of the first and second driving pulleys, and another engaged portion is provided on the other, and both engagement portions are engaged with each other by engaging the engaged portion. Since the driving pulleys are connected so as to be able to transmit the rotation, the belts can always be arranged without slack even if the transmission belts vary in length.

In the massage device according to the third aspect, the guide pulley that bridges the middle portion of the transmission strip member is attached to the pillow base, so that the guide pulley is attached to the guide rail. For example, since a rib formed for reinforcement inside the guide pulley can be used as a support portion of the pulley, it is not necessary to separately provide a support member for the guide pulley,
The weight can be reduced.
