PROBLEM TO BE SOLVED: To constitute a buffer mechanism which consists of a small number of components and can swing in 360 deg. directions. SOLUTION: An engagement member 13 is fixed to the lower end of the support shaft 2 of a pan receiving member 1, and the pin member 3 of the support shaft 2 is positioned at a pin arrangement part 10 formed at a boss part 9. The engagement member 13 normally abuts against the lower end edge 9a of the boss 9 with the elastic force of a coin spring 12, and then the support shaft 2 stands vertically to transmit a load placed on a scale pan 15 to a load receiving member 4. When a partial load is placed on the scale pan 15, the elevation of the support shaft 2 along the axis, the rotation on the pin member 3 and the leaving of the pin member 3 from the pin arrangement part 10 are combined together and then the scale pan 15 is displaced in the direction where the partial load is placed whichever direction the partial load is placed, thereby absorbing the load.
