ある。Considering the structure shown in the drawings as a prior art, this structure has a single ratchet mechanism, and even if it is operated from the closed position to the open position, the structure is open. Even when the operation is performed from the posture to the closed posture, the operation of the rocking body 3 in the reverse direction can be prevented. Further, in this structure, when the rocking body 3 is set to the open posture or the closed posture, the engagement / disengagement piece 16A of the vibration restraining member 16 is switched in the direction of the opening / closing axis X by the urging force of the spring 35. In this case, the teeth 15A of the gear-shaped member 15 corresponding to this area have been removed. However, when an area where the engagement piece 16A and the tooth body 15A do not contact each other is formed as described above, an area where the ratchet mechanism does not function when the oscillator 3 is set to the open posture or the closed posture is formed. That is, a so-called "asobi" was generated. Specifically, as shown in FIG. 8 (a), when the swing member 3 is operated in the open posture in the state where the swing body 3 is in the closed posture, the engagement / disengagement piece 16A becomes the tooth body 15A.
After reaching the swinging posture over one of the two (the rightmost toothed body 15A shown in the figure), the swinging in the reverse direction is prevented, and the engaging and disengaging piece 16A goes over the one toothed body 15A. Up to this point, the rocking body 3 can be freely rocked. The angle region in which the swinging operation can be freely performed in this way is “Asobi”, and in such a case where “Asobi” occurs in such a wide angle range, for example, the swinging body 3 is operated in the closing direction to operate the last tooth body 15A. After the disengagement piece 16A has passed over, the swinging body 3 can freely swing in this "asobi" area. Therefore, the effective range of the ratchet mechanism is narrower than the swinging range of the swinging body 3. And the operator moves the rocking body 3
May be erroneously swung in the opposite direction despite trying to stop in the range where the ratchet mechanism is working.

When the operation is performed from the open position to the other side, the swing regulating member 16 is linked with the operation start.
Is set to a position that prevents operation in the reverse direction, and when the operation is performed up to the operation end, the swinging body 3
In order to allow the switching of the posture of the swing regulating member 16 when the is operated in the reverse direction, "asobi" of a wide angle range is necessarily formed at each operation end, so that there is room for improvement.

The point is that a mechanism for reliably performing the operation up to the end is rationally configured.

傍まで揺動体を確実に揺動させ得るものとなる。According to the first feature, the swinging posture of the swing regulating member is determined in a toggle manner by the biasing force of the main biasing means, and the biasing force from the main biasing means acts in this manner. The engaging piece and the teeth of the gear-shaped member come into contact with each other to allow the swinging body to swing in a predetermined direction, while preventing the swinging body from swinging in the opposite direction. Alternatively, the switching means switches the posture of the swing restricting member when the opening posture is reached, so that the swing operation in the reverse direction is prevented until just before the switching to reach this posture. In other words, in this configuration, by providing a pair of engaging and disengaging pieces, the area where the teeth of the gear-like member do not contact the engaging and disengaging pieces can be made sufficiently small as in the structure shown in the related art, so This makes it possible to make the swinging body swing to the vicinity of the swinging end in a state where the swinging body can be made smaller and the operation in the opposite direction is prevented.

The posture of the swing regulating member is switched in cooperation with the movement. That is, according to this configuration, the posture of the swing regulating member is switched after the operating member exceeds the neutral posture, so that, for example, even if the operating member may be left in the neutral posture, the swing regulating member is The posture before operation is maintained, and the swing regulating member is not left in the neutral posture.

ったのである。[Effects of the Invention] Therefore, while a single ratchet mechanism prevents operation in the opening and closing directions, the operation in the opposite direction is prevented, but the "sound" at the swinging end is sufficiently reduced. The mechanism for reducing the size of the rocking body and reliably performing the operation up to the rocking end was rationally configured.
Further, regardless of whether the ratchet mechanism causes one of the pair of engagement pieces to function by swinging beyond the neutral position, one of the engagement and disengagement pieces can always be set at a position where it can be disengaged. It is possible to easily manufacture a product that always sets the mating piece at a position where it can be disengaged, and switches the posture of the swing regulating member that swings in a toggle manner based on a change in the posture of the operating member that swings in a toggle manner. By adopting the structure, even though the ratchet mechanism has a pair of engaging pieces, one of the engaging pieces can always be set at a position where it can be disengaged. It was gained.

い易いものとなっている。As described above, while the present invention uses the ratchet mechanism B having the single swing regulating member 16, the arm 3 is operated from the closed position "closed" or the open position "open". In this case, one of the pair of engagement / disengagement pieces 16A, 16A of the swing regulation member 16 is
To prevent the operation in the reverse direction during the operation, and to perform the reliable operation up to the swing end. In addition, when the swing end is reached, the swing The other of the pair of engagement / disengagement pieces 16A, 16A is changed to the gear-like member 15 by forcibly switching the posture of the movement regulating member 16.
The structure that switches the direction in which swing is allowed by contacting the tooth body 15 </ b> A of the first embodiment does not substantially generate “asobi”. While being forced to switch over the neutral position, the swing restricting member 16 is connected to both the pair of engaging and disengaging pieces 16A, 16A by the teeth 15 of the gear-shaped member 15.
The ratchet mechanism B can be reliably operated in any swing direction while avoiding the inconvenience of being left in a neutral position in which the ratchet mechanism B does not come into contact with A. In particular, when the closed posture “closed” is reached by the operation from the open posture “open”, the rocking operation in the reverse direction (opening direction) is permitted, but the closed posture “closed” is maintained by the lock mechanism B. Therefore, the arm 3 does not swing in the opening direction due to an erroneous operation, and is easy to use.
