As shown in figure 28, if 60 opposite 1st component 50 of the 2nd component is made to topple over to the directions arrow B, floating wedge component 70
The flank of tooth 72 and gear part 66 form meshing state.In addition, floating wedge component 70, which is pressed into, is formed in wedge surface 58a and gear part 66
Between the space become narrow gradually.Therefore, floating wedge component 70 is carried out by the 2nd component 60 of wedging action pair to the swing in the directions B
Limitation, to maintain the angle of inclination of (fixed to keep) the 1st component 50 and the 2nd component 60.
That is, under the meshing state shown in Figure 28, by the flank of tooth 72 of floating wedge component 70 and engaging for gear part 66,
2 components 60 will not slide, and can certainly keep the angle of inclination of the 1st component 50 and the 2nd component 60.
On the contrary, if making the 2nd component be swung to the directions arrow A, as shown in figure 29, due to based on wavy ring portion 85
Spring force and the towing rotating friction force generated, wedge activation part 81 will start to rotate jointly together with the 2nd component 60.Therefore,
Floating wedge component 70 will downwards move in wedged window oral area 58.Also, the upper surface of floating wedge component 70 is by wedge Actuator Division
The taper surface 82b of part 81 is pushed.Therefore, the guiding slope surface 58c sliding contacts on 70 one side of floating wedge component and wedged window oral area 58,
It is slightly moved to away from the direction of gear part 66 on one side.Then, floating wedge component 70 in the lower part of wedged window oral area 58 to by
The direction movement of nearly wedge surface 58a.Therefore, small gap, and floating wedge component will be generated between the flank of tooth 72 and gear part 66
70 form non-contact free state (Figure 29).Under non-contact free state, floating wedge component 70 is drawn by wedged window oral area 58
Lead slope surface 58c, the taper surface 82b of wedge activation part 81 and staggered floor portion 82c this 3 dot point.Under non-contact free state, due to
Floating wedge component 70 is not in contact with gear part 66, therefore not will produce the sound of ear-piercing ticktack ticktack, and the 2nd component
60 will undisturbedly swing to the directions arrow A.In addition, generating towing spin friction between wedge activation part 81 and the 2nd component 60
During power, since floating wedge component 70 is pushed by wedge activation part 81 from top, the flank of tooth 72 will not be mutual with gear part 66
Engagement.

Ring and be kept, to keep floating wedge component 70 the flank of tooth 72 and gear part 66 contactless state.
As shown in figure 30, if the 2nd component 60 is made further to be swung to the directions arrow A, and by being pushed away under a side with prominent
Playing the upper surface that portion 67 pushes floating wedge component 70, then wedge activation part 81 will rotate jointly, meanwhile, floating wedge component 70 is by wedge
Activation part 81 pushes down on.Therefore, the protrusion 83a set on the plate spring component 83 of wedge activation part 81 will extend over position banking pin
57.Therefore, position banking pin 57 will be engaging in locking with recess portion 83b.Also, the lower face of floating wedge component 70 is incorporated in guarantor
Space 58b is deposited, to form preservation state.
Under preservation state, floating wedge component 70 is incorporated in shelf space 58b, also, plate spring component 83 is locking
With recess portion 83b engaging in position banking pin 57.Therefore, though if so that the 2nd component 60 is swung to the directions B can by engaging in
The spring force of the plate spring component 83 of position banking pin 57 keeps gear part 66 and 72 out of mesh state of the flank of tooth.Therefore, wedge start
Component 81 will not be rotated jointly, and the 2nd component 60 can freely be swung with respect to the 1st component 50 to the directions B.
In the following, as shown in figure 32, if the 2nd component 60 is made to be swung to the directions arrow B, will be reached in the 2nd component 60
Opposite 1st component 50 is formed before linear final expanded position, and floating wedge component 70 will be connected to protrusion 68 by above pushing away
Lower face.
Also, if the 2nd component 60 slightly swung to the directions arrow B at full tilt, above pushing away will be floated with protrusion 68
The lower face of wedge portion part 70 pushes up, to make floating wedge component 70 be moved upward from shelf space 58b.At this point, with floating
The movement of dynamic wedge portion part 70, the upper surface of floating wedge component 70 pushes up the taper surface 82b of wedge activation part 81.Therefore, wedge
Activation part 81 rotates the direction that rotates clockwise along Figure 32 centered on the L of axle center.Therefore, plate spring component 83 is locking with recessed
Portion 83b and the locking state of position banking pin 57 will be released from, guiding recess portion 83c of the position banking pin 57 to plate spring component 83
It is subjected to displacement.Also, due to the frictional force of wedge activation part 81 and the 2nd component 60, the two will rotate jointly.Therefore, floating wedge
Component 70 will be moved to the top of wedged window oral area 58 (wedge shape space), the flank of tooth 72 and the formation of gear part 66 of floating wedge component 70
Meshing state.
It should be noted that in the present embodiment, although 60 opposite 1st component 50 of the 2nd component is formed linear (180
Degree) position as final expanded position, but this may not be defined in.It is carried out by the range of the central angle to gear part 66 is arranged
Appropriate selection, for example, 60 opposite 1st component 50 of the 2nd component can also be formed to the position of 120 degree of angle as final expansion position
It sets.
Also, if making the 2nd component 60 be swung again to the directions arrow A, due to the spring force based on wavy ring portion 85
And the towing rotating friction force generated, wedge activation part 81 start to rotate jointly together with the 2nd component 60.Therefore, floating wedge portion
Part 70 moves downwards in wedged window oral area 58.Also, the upper surface of floating wedge component 70 is by the taper of wedge activation part 81
Face 82b is pushed.Therefore, the guiding slope surface 58c sliding contacts on 70 one side of floating wedge component and wedged window oral area 58, on one side to away from
It slightly moves in the direction of gear part 66.Therefore, because floating wedge component 70 the lower part of wedged window oral area 58 close to wedge surface 58a
Configuration, will generate small gap, floating wedge component 70 forms non-contact free state again between the flank of tooth 72 and gear part 66
(Figure 29).Therefore, the sound of ticktack ticktack is not will produce.Also, it if the 2nd component 60 is made to be swung to the directions arrow B, floats
The flank of tooth 72 of wedge portion part 70 forms meshing state with gear part 66.Further, floating wedge component 70, which is pressed into, is formed in wedge surface 58a
The space become narrow gradually between gear part 66.Therefore, floating wedge component 70 by the 2nd component 60 of wedging action pair to the directions B
Swing limited, and the angle of inclination of (fixed keep) the 1st component 50 and the 2nd component 60 is maintained, to restore Figure 28 institutes
