<p>PURPOSE:To provide a device which generates a compact and effective gate opening closing auxiliary force. CONSTITUTION:A push-up link 30 is attached to a first hinge 32 arranged to the side part of a gate. The lower end of the push-up link 30 is coupled to a first rotation link 35 through a second hinge 36. The first rotation link 35 is supported to a body 11 through a third hinge 37. A sublink 41 is coupled to the first rotation link 35 through a fourth hinge 40. The sublink 41 is coupled to a second rotation link 50 through a fifth hinge 45. The first and second rotation links 35 and 50 and the sublink 41 constitute a parallel mechanism 52. A rod 55 is coupled to the second rotation link 50. The rod 55 is energized in a direction, in which the second rotation link 50 is rotationally raised, through the force of a spring 65.</p> |
