And to correct the pelvis properly and safely by pressing the coccyx using the weight of the present invention relates received treatment themselves. SOLUTION: A cylindrical body casing 7, place the coccyx contact treatment unit body 9a which is operatively disposed in the vertical direction via the elastic body 10 is provided with a coccyx portions contact the buffer member 11 such as by a sponge at its upper end. Across the coccyx contact portions shock absorber 11, take the attitude that sit on top of that, who received treatment, placed on the contact portions 11 coccyx cushion the coccyx. Then push up from the bottom toward the top of the coccyx coccyx 11 parts contact buffer body weight and floated lightly from the floor in the posture of both feet as it is.
