<p>PROBLEM TO BE SOLVED: To reduce the number of components and to improve assemblability into a door by a method wherein a door is made to be capable of being placed in a superlock state by a guide part and the engaging part of a link attached to a base. SOLUTION: One end part is engaged with an actuator lever 16, an engagement part 38 at the other end part is engaged with the guide part of a base, and a link 20 coupled to a first lock plate 17 is provided. The engagement part 38 of a lick 20 moves a first guide part 21a according to rotation of the actuator lever 16 between a lock position and an unlock position and moves a second guide part 21b according to rotation between a lock position and a superlock position. When the engagement part 38 is positioned at a guide part 21b, the first lock plate 17 is brought into a non-rotatable state through rotation operation of a second lock plate 18 to the unlock position side. Thereby, a need for a support plate is eliminated, the number of parts is reduced, and ability of assembly into a door is improved.</p> |
