When it is rotated around 52, the lock member 6 is in the raised state (protruding state) as shown in FIG. In this state, a gap 368 is formed between the lock member 6 and the block 5.
Occurs. Further, the free end portion 371 of the spring member 317 enters into the groove portion 354e of the block 5 and meshes therewith.

When the ejecting force P is applied to the lock member 6 from the state shown in FIG. 17, the ejecting state shown in FIG. 18 is obtained. At this time, when the lock member 6 is pushed in the traveling direction until the gap 368 disappears, the tip surface 305 of the block 5 is pushed.
The tip of the lock member 6 hits. Further, since the shaft hole 362 moves together with the lock member 6, the flat surface portion 353 of the rotating shaft 352 and the sliding surface 353 of the second hole portion 365 come into contact with each other, and the lock member 6 cannot rotate at this point. At this time, the free end portion 371 of the spring member 317 rides on the taper portion 354c of the block 5, so that the spring member 317 is deformed.

After disconnecting the mating connector 80, FIG.
When the ejecting force 365 indicated by the arrow is released, the restoring force of the deformed spring member 317 pushes the lock member 6 back in the backward direction (removal direction), returns to the state of FIG. 17, and the lock member 6 becomes rotatable. . In this way, a connector with a disconnection mechanism in which the lock does not rotate during ejection is obtained.

Even with the construction of the lock member 6 and the block 5, the free end portion 371 of the spring member 317 moves over the first groove portion 354a when the lock member 6 is switched among the three states. Since it rides on the circular arc surface, a click feeling can be obtained when switching.
