PURPOSE:To loosen severe requirements to processing and assembling accuracy and to decrease the variance of products, by providing a recess only one side of a surface plate of a supporting point and making the other side flat for point contact. CONSTITUTION:A recess is provided for only one side of prescribed positions (at least, two positions) of the surface plate, and the other side is made flat, and the plate is clipped with acuminations of pivots 10 provided for channel-shaped arms 8, 9 of a coupling body. Further, the coupling body is fitted to one end of a plate spring, and the other end of the plate spring is fixed to a support. In the constitution above, the effect of friction is halved for the force transmitting section between the surface plate 1 and the plate spring in comparison with the surface contact. Further, the requirement of eccentricity needed for the provision of recess for both front and back sides is not taken into account, and the severe requirements of the processing accuracy is loosened. |
