<p>The purpose of the present invention is to reduce malfunctions caused by friction between two lids, friction between a lid and a main body etc. One end of a link (for example a second link) is axially fixed to an arm part (for example a first arm part) of a first lid. A shaft (for example a movable shaft) and a hole (for example a connecting hole) in which the shaft (for example the movable shaft) engages, are provided between the other end of the link (for example the second link) and an arm part (for example the second arm part) of a second lid. In this hole (for example the connecting hole), unlocking by pressing on the first lid allows movement of the shaft (for example the movable shaft) and a clearance (for example a large diameter part) that cuts off the transmission of rotation force is formed.</p> |
