Chain component 5, but the larger external force is not easy to act on housing 9 or rotor 10.Therefore, in the present embodiment, even if first
Effect has larger external force on hinge member 4 or second hinge component 5, can also inhibit rotor 10 radial direction upper recess 9c it is outer
Side 9d and the deviation of the relative position of spool 13, as a result, the reduced performance of fluid damper 3 can be inhibited.
In the present embodiment, by the slewing area limiting mechanism 21 being configured at outside fluid damper 3, cut with scissors to second
Chain component 5 is limited compared with the slewing area of first axle component 4.Therefore, in the present embodiment, stream need not be used
The housing 9 and rotor 10 of body damper 3 limit second hinge component 5 compared with the slewing area of first axle component 4.
Therefore, in the present embodiment, it can prevent that effect has second hinge component 5 on first axle component 4 or second hinge component 5
Compared with the rotation direction of first axle component 4 larger external force when fluid damper 3 damage.In addition, in present embodiment
In, slewing area limiting mechanism 21 is formed by limiting groove 4d and banking pin 18, accordingly, it is capable to by comparing simple structure to second
Hinge member 5 is limited compared with the slewing area of first axle component 4.
In the present embodiment, it is configured in the longitudinal direction on the side surface part 5a on the inside of two side surface part 4a and is fixed with stream
The housing 9 of body damper 3.Therefore, in the present embodiment, easily housing 9 can be fixed.In addition, in this embodiment party
In formula, since housing 9 is fixed on side in a manner that larger 14 one side of fluid chamber of the outer diameter of housing 9 is configured at base portion 5b one sides
Portion 5a, therefore the upper surface stretching of the slave side surface part 5a of housing 9 when second hinge component 5 is configured at closed position 5B can be reduced
Overhang.Therefore, in the present embodiment, the hinge 1 when can make the second hinge component 5 be configured at closed position 5B is in vertical direction
Upper miniaturization.
In the present embodiment, when second hinge component 5 is rotated from open position 5A towards closed position 5B, Torsion coil bullet
Spring 22 is rolled tightly in rotary middle spindle 6.Therefore, in the present embodiment, it can make torsion-coil spring 22 that there is spring clutch
Function.Therefore, in the present embodiment, second hinge component 5 can be made in second hinge component 5 compared with first axle component 4
Slewing area centre position stop.
(other embodiment)
The above embodiment is an example of the preferred embodiment of the utility model, but it's not limited to that, can not changed
Various modifications are carried out in the range of change the utility model purport.
In the above-described embodiment, first axle component 4 is fixed on but it is also possible to be only in the both ends of rotary middle spindle 6
The one end of rotary middle spindle 6 is fixed on first axle component 4.In this case or in the not solid of rotary middle spindle 6
The preventing portion that comes off is formed with due to the other end of first axle component 4, this comes off preventing portion for preventing 6 court of rotary middle spindle
Front-rear direction comes off.In addition, in this case, the both ends of rotary middle spindle 6 are also supported on first axle component 4.
It is inserted into the above-described embodiment or respectively and is sticked in two banking pins installation of two limiting groove 4d
In second hinge component 5.In this case, be respectively fixed with banking pin on two side surface part 5a, two banking pins respectively from
The outsides of each side surface part 5a to front-rear direction in two side surface part 5a protrude.
In the above-described embodiment, hinge 1 can not also include slewing area limiting mechanism 21.In this case, for example,
Can also be that second hinge component 5 is turned compared with first axle component 4 by the housing 9 and rotor 10 of fluid damper 3
Dynamic scope is limited.In addition, in this case, for example, it can be fixed with the main bodys such as the refrigerator of first axle component 4
It is upper to form the abutting part abutted for second hinge component 5 or lid 2 and right by the abutting part and second hinge component or lid 2
Second hinge component 5 is limited compared with the slewing area of first axle component 4.
In the above-described embodiment, as long as need not make second hinge component 5 in second hinge component 5 compared with the first hinge
The centre position of the slewing area of chain component 4 stops, then hinge 1 can not also include torsion-coil spring 22.In addition, above-mentioned
In embodiment, for example, it can be the first contact site is formed on first axle component 4, formed on second hinge component 5
The second contact site that can be contacted with first contact site, and the first contact site and the second contact site are formed as according to the second hinge
Chain component 5 changes the contact of the first contact site and the second contact site compared with the turned position of first axle component 4, by
This, makes second hinge component 5 stop in second hinge component 5 compared with the centre position of the slewing area of first axle component 4.
Configure two side surface parts in the above-described embodiment or in the inside in the front-back direction of two side surface part 5a
4a.In addition, in the above-described embodiment or housing 9 is fixed on first axle component 4, the both ends of rotary middle spindle 6
It is fixed on second hinge component 5.In addition, being formed in the above-described embodiment or in fluid damper 3, there are two streams
Body room 14.In addition, in the above-described embodiment or rotary middle spindle 6 axially with respect to horizontal direction tilt.This
Outside, the viscous fluid in addition to oil is filled in the above-described embodiment or in fluid chamber 14.
