CONSTITUTION: A basic body 1, a turning body 11, and a pair of link arms 16, 21 turnably connecting the basic body 1 stored in the turning body 11 with the turning body 11 are provided. Next, a cam part 25 is formed in an end part on a basic body 1 side of the link arm 21 positioned on an outer side. A spring 26 is arranged in the basic body 1, and a pressure contact part 28 formed at one end thereof is brought into contact with the cam part 25 and is pressed. When a door 52 is closed and the turning body 11 comes into contact with the basic body 1, the cam part 25 is brought into pressure contact by the pressure contact part 28 to keep a closed condition of the door 52.</p> |
