The contact surface 73'' of the hook portion 73n may be disposed at a predetermined angle with the support portion 73m. The support portion 73m may extend toward the rear of the door 20. Accordingly, the contact surface 73'' may be disposed at a predetermined angle with the angle facing the rear of the door 20.

The predetermined angle may not be vertical. The predetermined angle may be an angle that prevents the latch guide 76 from restricting the movement of the hook portion 73n when the contact surface 73'' of the hook portion 73n moves forward.

When the door 20 is in the closed position, the door lock 100 may be positioned to be spaced from one end of the latch guide 76 close to the hook portion 73n in a direction away from the hook portion 73n.

The contact surface 73'' of the hook portion 73n may be arranged to be spaced apart from the door lock 100 when the door 20 is in the closed position.

The lower end of the hook portion 73n is moved higher than the end of the latch guide 76, the door 20 is opened, and the door latch 73 can be moved forward. Thereafter, the lower end of the hook portion 73n comes into contact with the latch guide 76, so that the door latch 73 can be moved. This is because the door latch 73 receives elastic force from the bottom.

The door latch 73 may be moved to the outside of the body through the hook opening 75 and/or the insertion opening 17. Thereby, the door 20 can be moved to the open position.
