<p>PURPOSE:To facilitate assembling and to obtain the highly accurate device by constituting a weight stopper in an L shape or in an I shape. CONSTITUTION:An L-shaped weight stopper 8 is used for regulating displacement. Therefore, the weight stopper 8 can be assembled only by inserting the stopper from the tip part of a weight 1 into the lower side of the weight 1. Therefore, the weight stopper 8 can be readily assembled with an automatic machine.</p> |
