It is arranged so as to be slidable in the direction of arrow X while being guided by zero. In that case, a portion of the slide member 9 closer to the tip end than the guide member 10 is formed into a thin portion 11 that can be bent and deformed in an arrow Y direction substantially perpendicular to the slide direction,
A lock claw 12 is formed on a side surface of the thin portion 11 and on a side opposite to the direction in which the thin portion 11 can be flexibly deformed. The lock claw 12 protrudes out of the main body from an opening 2A provided in the main body 2.
The cam surface 13 with which the transmitting unit 3 contacts when the transmitting unit 3 is folded is attached to the protruding tip of the lock claw 12.
Is formed. In addition, a spring 14 is provided between the lock release operation button 8 and the guide member 10, and the whole of the lock release button 8, the slide member 9, and the lock claw 12 is moved in the direction of the arrow X by the force of the spring 14. It is configured to be biased in the opposite direction.

And the entrance 15B at which the lock claw 12 is disengaged from the locking recess 15 by the movement of the transmission section 3 in the extension direction when the lock claw 12 is moved in the X direction. And a cam surface 16 is formed beside the entrance portion 15B and at the corner of the transmitting section 3 on the inner rear portion 15A side. In that case, the cam surface 16 of the transmitter 3
Is located at a position where it comes into contact with the cam surface 13 of the lock claw 12 when the transmitting section 3 is folded,
By the contact of 6, a force is generated in the lock claw 12 to deflect the thin portion 11 in the direction of the arrow Y.

That is, the thin portion 11 of the slide member 9 is indicated by an arrow Y
The locking claw 12 moves in the direction of being retracted into the main body, and moves over the transmitter side cam surface 16 by this movement, and then moves in the returning direction to engage with the inner back part 15A of the locking recess 15. Thus, the transmission unit 3 is locked. Therefore, at the time of this automatic lock, the slide member 9 does not perform the slide motion in the direction opposite to the arrow X direction,
The lock release operation button 8 does not show unnecessary movement.

命を延ばすことができる。As is apparent from the above description, according to the present invention, when the transmitting section is folded from the extended state, the lock claw comes into contact with the cam surface on the side of the lock concave portion, thereby causing the slide. Since the thin portion of the member is bent and deformed in a direction substantially perpendicular to the sliding direction of the slide member, and this deformation causes the lock claw to be engaged with the locking recess,
No sliding movement of the sliding member occurs at the time of automatic locking, so that unnecessary movement of the unlocking button can be eliminated. Further, the number of movements of the slide member in the sliding direction is halved as compared with the conventional device shown in FIG. 7, so that the life of the spring biasing the slide member in the direction opposite to X can be extended.
