PROBLEM TO BE SOLVED: To provide a bed preventing trouble such as a fall in the service life of a vibration generator or its damage by suppressing the generation of bending stress to a vibrating plate and a floor frame even when a user stands up on the bed, kneels down or jumps up and down. SOLUTION: The bed 1 is composed of the vibration generator 10 including a vibrator 11 and a vibrating plate 13 fastened to the vibrator 11 by bolts 12; and a mattress 20 including a bottom 21 formed of urethane, and a spacer 24 having a recess 22 for enclosing the vibrator 11, and an upper face part 23 for placing the vibrating plate 13, and suitable for the bottom 21 and formed of urethane. When external force is applied to the vibrating plate 13, the spacer 24 moves independently of the bottom 21, and the vibrating plate 13 follows the spacer 24. COPYRIGHT: (C)2011,JPO&INPIT |
