That is, when the distance between the engaged portion 1 on the door 2 side and the engaging member 3 on the floor side in a lying posture is a specified value, as shown in FIG. 1B, the engaging member 3 on the floor side is When the door 2 is engaged with the engaged portion 1 on the side of the door 2 and is inclined obliquely upward, the lower end surface 5a (the lower end surface of the magnet 15) of the engaged portion 1 of the door 2 (mounting member 5) and the floor. The front end surface of the side engaging member 3 is configured to be substantially parallel to each other. Therefore, as shown in FIG. 3, when the distance D between the floor surface 4 and the lower end surface of the door 2 is smaller than the specified value, the engagement member 3 engages with the engaged portion 1 on the door 2 side. The inclination angle becomes small when it is inclined obliquely upward, and the engagement member 3 on the floor side is lower than the lower end surface 5a (the lower end surface of the magnet 15) of the engaged portion 1 (mounting member 5) on the door 2 side. Although the front end side surface of the is inclined forwardly downward and not shown, when the distance D is larger than a specified value, the engaging member 3 is slanted to engage with the engaged portion 1 on the door 2 side. The tilt angle when the tilted posture is upward becomes large, and the floor-side engaging member 3 is opposed to the lower end surface 5a (the lower end surface of the magnet 15) of the engaged portion 1 (mounting member 5) on the door 2 side. The tip side surface inclines forward and upward, but in any case, when the distance D is within a certain range, the square hook-shaped engaging portion 14 of the engaging member 3 is attached. The fitting portion 13 is fitted to the engaged portion 1 on the door 2 side so that the fitting portion 13 fits horizontally into the recess (fitting portion) 16 in the engaged portion 1 on the door 2 side. In the state of being fitted in the concave portion (fitting portion) 16 in the above, a marginal space is secured between the fitted parts so that relative movement in the vertical direction is possible.

る。According to the door locking device of the present invention which can be implemented as described above, the floor side engaging member is pulled up to the obliquely upward inclined posture by the magnet of the door side engaged portion. When the front end abutting surface of the engaging member comes into a door locking state in which the tip abutting surface abuts the abutting surface of the engaged portion, the fitting portion of the engaging member and the engaged portion are fitted together. When the door is in the door locking state, the door is locked at the locking position. There is no possibility that the floor-side engaging member will disengage from the door-side engaged portion and return to the laid-down posture unless it is moved in the direction to return it to the original position. Therefore, even if the magnetic holding force against the engaging member is weak for some reason, such as the magnet being weak or the relative positional relationship between the magnet and the engaging member being poor, it can be easily engaged when vibration or external force acts on the door. The inconvenience that the member is disengaged from the engaged portion and the door becomes free is eliminated, and the door can be reliably retained and retained at the engagement position. Of course, when unlocking the door, it is sufficient to simply move the door in the opposite direction, and no special operation such as unlocking is required.
