When the pressing end 31a of the elastic bar 31 is pressed, the elastic bar 31 enters the housing 21 while compressing the spring, and when the pressing force is removed, it returns to the initial position.

The battery 35 is a rechargeable battery and supplies all the power required to drive the lock check device 20 . The battery 35 is charged by power applied from the outside.

The signal output means generates a signal in association with the reciprocating motion of the latch bar 31 . For example, when the external door 15 is completely closed, a signal indicating that the closed signal is output, and when the external door 15 is opened, an open signal is output. The signal output from the signal output means is transmitted to the control unit 37 .

Signal output means, the driven plate 28, the third spring (28g), the pressing block (28e), the entry completion sensor (29c) is included.

The driven plate 28 is a plate-shaped member having a certain thickness, and crosses the upper portion of the first spring 26 in a state supported by the support block 29 . The driven plate 28 has a straight extended portion 28a in which both ends are supported by the sliding groove 29a of the support block 29, and a side protrusion 28d integrally formed on both sides of the straight extended portion 28a in the width direction. .

The linear extension (28a) is capable of sliding movement in the longitudinal direction in a state supported by the support block (29). The sliding movement distance of the linearly extended portion 28a is limited to the extent that the end of the linearly extended portion 28a does not deviate from the sliding groove 29a.

One end of the third spring 28g is connected to one side protrusion 28d of the side protrusions 28d. The other end of the third spring 28g is connected to the lower support block 29 in the drawing, as shown in FIG. 3 . The third spring 28g is a tension spring and elastically supports the driven plate 28 in the direction of the arrow g.

In addition, a pressing block 28e is installed on the other side protrusion. The pressing block 28e is a member opposing the entry completion sensor 29c, and presses the entry completion sensor 29c in a state in which the driven plate 28 moves in the direction of the arrow g. The entry completion sensor 29c is a pressure sensor for detecting a pressure, and generates a signal when the pressure block 28e is pressed. The signal output from the entry completion sensor 29c is transmitted to the control unit 37 .

Reference numeral 22 is a guider for guiding the linear motion of the latch 23 and the elastic bar (31).

On the other hand, as described above, the cover 41, the handle 45, the communication unit 43e, the motion sensor 43f, the warning lamp 43c, and the sound generator 43a are disposed. The communication unit 43e, the motion sensor 43f, the warning lamp 43c, and the sound generator 43a have been described above.
