フリーストップに停止させることが可能となる。When the first push button 19 is pushed rightward from this state, the pushing force is applied via the second push button 20 to the lock member 17.
The lock member 17 is first slid to the right in the figure against the pressing force of the compression spring 18, so that the locking projections 17a and 17a of the lock member 17 and the first portion of the transmitter section 1 side. After the engagement between the lock grooves 2a, 2a of the mounting portion 2 is released, the pressing cam portion 19b comes into contact with the inclined portion 16a of the pressure receiving cam portion 16 and presses the inclined portion 16a, so that the rotor 13 shown in FIG. As shown, it rotates counterclockwise and opens the earpiece 5 slightly. Then, as shown in FIG. 5, the engaging portion 13b of the rotor 13 is engaged with the engaging groove 1 of the stator 10.
Since the end portion of the torsion spring 14 which is in the compressed state in the wound state when it reaches the position 0b moves to the left in the drawing and is locked by the locking portion 13b, the rotor 1
3 receives the urging force that rotates in the counterclockwise direction as shown in FIG. 6, so that the earpiece 5 which is slightly opened as described above is further automatically opened by the elastic force of the torsion spring 14. At this time, since the other end 14b of the torsion spring 14 is locked down to the locking portion 13b in the compressed state, it does not come off from the locking portion 13b regardless of the existence of the inclined portion 13c. When the earpiece 5 is opened with respect to the transmitter 1 to a certain opening angle, the torque of the torsion spring 14 weakens, and the second convex portion 13d of the rotor 13 becomes the first convex portion 1 of the stator 10 as shown in FIG.
Since it comes into pressure contact with 0a and 10a, it becomes possible to stop the receiver section 5 in a free stop within a predetermined opening angle range by this frictional action.

とがない。When the opened earpiece 5 is closed, the torsion spring 14 is wound up to a predetermined closing angle, but when the predetermined closing angle is reached, the resistance of the torsion spring 14 to be wound up increases. Finally, the other end 14b slips off the inclined portion 13c of the locking portion 13b,
The stator 10 is pushed (compressed) in the axial direction at its edge.
Since it is locked while being caught in the locking groove 10b of
At the closing angle thereafter, only the rotor 13 and the torque of the torsion spring 14 do not act on the earpiece 5.

The locking projections 17a, 17a of the first mounting portion 2 on the side of the transmitter 1.
It engages with the lock grooves 2a, 2a provided on the front end of the receiver, and locks the receiver 5 with respect to the transmitter 1 in a folded state.
