Claims

[Scope of utility model registration request]

A lever body is provided with a fulcrum at one end and a force point at the other end, and a drive rod having a spherical surface at the tip gives displacement to the force point of the lever, and the lever body has a spherical surface at the tip. in which the reduced displacement is taken out by a driven lever equipped with a driven lever, in which the spherical center of each spherical portion of the driving lever and the driven lever is arranged on a straight line perpendicular to the center of rotation of the fulcrum of the lever body. A displacement reduction device characterized by:
