PURPOSE:To perform linear motion of a long stroke, by both rotatably connecting a rocking arm to an intermediate arm, in length equal to that of said rocking arm, at one end and linking said intermediate arm to a driving arm through a link rod. CONSTITUTION:When a driving arm 15 is rotated clockwise through a motor 14, the locus of a pin 13 at the other end of an intermediate arm 8 is displaced rocking at a same angle for the core of bearing devices 3 and a pin 9, as a result a slide bar 12 is linearly displaced largely for a rotary angle of the driving arm 15, and the slide bar 12 reaches the forward movement end of a stroke under a condition for the driving arm 15 to reach a position of 180 deg., simultaneously the slide bar 12 shuttles one time with a long stroke about five times as long as the rotary radius of the driving arm by ratio length of links as shown by the drawing under a condition for the driving arm 15 at 360 deg., that is, returned to a position of 0 deg.. |
