Abstract

PURPOSE:To remove backlash present more or less between the metal arm and the device frame supporting it freely slidably, by forcibly pressing the metal arm to one side against the elasticity of spring. CONSTITUTION:Inside the celing plate b1 having lengswise long hole 18, a movable plate 20 which moves orthogonal to the metal arm 1 in parallel with a transversal moving plate 19 is fitted via the engagement of a breadthwise long hole 21 and an engaging pin 22. This movable plate 20 is pressed at all times to one side with a spring 23. When a push-button 11 is depressed against the restoring spring 25, the metal arm 1 slides forward, the projection 17 is operated with slanting part 24, and a force against the spring 23 is exerted to the operating part. As a result, the metal arm 1 is compulsively pressed to one side (right direction, in figure) with the elasticity of the spring 23, allowing to remove backlash present more or less between the metal arm 1 and the device frame B supporting it freely slidably.
