<p><P>PROBLEM TO BE SOLVED: To simplify an interlocking mechanism for interlocking and connecting a control lever on the lateral vicinity of a driver's seat with a control valve which is provided on the lower side of the control lever in a manner displaced back and forth, and right and left. <P>SOLUTION: Interlocking links 56 and 57 for interlocking and connecting link connecting portions 72 and 68c on the side of the control lever 49 with spools 54 and 55 of the control valve 52 are bent, so that lower end sides of the interlocking links 56 and 57 can be positioned near the spools 54 and 55. The lower end sides of the interlocking links 56 and 57 are pivotally supported on and connected to oscillating arms 83 and 84 which can be freely oscillated around a pivot 88. The spools 54 and 55 are pivotally supported on and connected to the oscillating arms 83 and 84 so as to be linearly moved by the oscillation of the oscillating arms 83 and 84. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
