<p><P>PROBLEM TO BE SOLVED: To provide an opening/closing adjusting mechanism of an opening/closing lid for forming a vent passage which is provided in a vent device such as an intake device and a ventilation equipment and an expansion and contraction mechanism which is used in other proper use and is hard to break down. <P>SOLUTION: The expansion and contraction mechanism includes two sliders 1,2 slidably combined in front and back direction, and an energizing means 3 for energizing both of the sliders 1,2 in direction making the sliders 1,2 apart from each other. A latch member 4 having a pawl part 4a is attached to one slider 1, and a guide path 5 that guides the pawl part 4a is provided to the other slider 2. The guide path 5 has a loop shape from its rear part through its front part back to its rear part and has a substantially linear part 5c in a part from its rear part down to its front part. The pawl part 4a is latched into latch stages 6a, 6b which are provided to the substantially linear part 5c and a condition that both of the sliders 1,2 are stopped is maintained. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
