因此，切削刀片22可被设置成远离多个凹槽侧面抵接表面88，使得每个非侧向转位间隙85不被相应的转位闩锁54占据。
Thus, the cutting insert 22 can be disposed away from the plurality of pocket side abutment surfaces 88 so that each non-lateral indexing gap 85 is unoccupied by a respective indexing latch 54.
在具有两个侧向转位间隙90的第一可选构造中，至少一个侧向转位间隙90不被相应的转位闩锁54占据。
In a first optional configuration having two lateral indexing gaps 90, at least one of lateral indexing gaps 90 is unoccupied by a respective indexing latch 54.
在仅具有一个侧向转位间隙90的第二可选构造中，侧向转位间隙90可以被占据，也可以不被占据。
In a second optional configuration having only one lateral indexing gap 90, the lateral indexing gap 90 may or may not be unoccupied.
在这样的前述状态下，切削工具20处于第一中间位置。
In such foregoing states, the cutting tool 20 is in the first intermediate position.
如果没有被转位闩锁54占据的侧向转位间隙90，则切削刀片22可围绕刀片中心轴线A在两个方向上自由旋转。
If there are no lateral indexing gaps 90 occupied by an indexing latch 54, the cutting insert 22 is freely rotatable in both directions about the insert central axis A. Otherwise, the cutting insert 22 is freely rotatable in only one direction about the insert central axis A. In this non-limiting example shown in the drawings, only the first lateral indexing gap 90 ais unoccupied by a respective indexing latch 54.
参照图10，在切削工具20的第二中间位置，切削刀片22围绕刀片中心轴线A旋转，使得每个非侧向转位间隙85与相应的刀片侧面抵接表面64在角度上对准，并且每个凹槽侧面抵接表面88与相应的转位闩锁54成角度地对准。
Referring to FIG. 10, in the second intermediate position of the cutting tool 20, the cutting insert 22 is rotated about the insert central axis A so that each non-lateral indexing gap 85 is angularly aligned with a respective insert side abutment surface 64 and each pocket side abutment surface 88 is angularly aligned with a respective indexing latch 54.
显然，任何转位间隙84都没有位于其中的转位闩锁54。
Clearly, none of the indexing gaps 84 have an indexing latch 54 located therein.
切削刀片22围绕刀片中心轴线A的进一步旋转导致每个非侧向转位间隙85与相应的转位闩锁54对准，在该阶段，每个转位闩锁54自由落入对应的非侧向转位间隙85中。
Further rotation of the cutting insert 22 about the insert central axis A results in each non-lateral indexing gap 85 being aligned with a respective indexing latch 54, at which stage each indexing latch 54 is free to fall into the corresponding non-lateral indexing gap 85.
随后固定螺钉28的紧固实现了切削工具20的第二紧固位置。
Subsequent tightening of the retaining screw 28 achieves the second fastened position of the cutting tool 20.
尽管已经以某种程度的特定性描述了本申请的主题，但应理解的是，在不脱离所附权利要求所述的本发明的精神或范围的情况下，可以做出各种改变和修改。
Although the subject matter of the present application has been described to a certain degree of particularity, it should be understood that various alterations and modifications could be made without departing from the spirit or scope of the invention as hereinafter claimed.
光纤的制造方法及光纤的制造装置
BACKGROUND OF THE INVENTION
本发明涉及光纤的制造方法及光纤的制造装置。
The disclosures herein generally relate to an optical fiber manufacturing method and an optical fiber manufacturing apparatus.
光纤的制造方法具有下述工序，即，在拉丝炉中，对玻璃母材进行加热熔融，将玻璃母材拉伸为玻璃纤维。
An optical fiber manufacturing method includes a process of heating and melting a glass preform in a drawing furnace so as to draw the glass preform into a glass fiber.
将该工序还称为“拉丝”。
The above process is referred to as a “drawing” process.
刚拉丝出的玻璃纤维为高温，因此无法直接涂敷保护用的树脂。
Thus, a protective resin cannot be applied to the glass fiber as it is.
因此，刚拉丝出的玻璃纤维在涂敷树脂前由冷却装置进行冷却(例如参照专利文献1)。
For this reason, immediately after the glass fiber is drawn, the glass fiber is cooled by a cooling device before the resin is applied (see Patent Document 1, for example).
专利文献1的冷却装置具有：冷却筒，其由冷媒进行冷却；以及壳体，其将该冷却筒收容于内部。
The cooling device described in Patent Document 1 includes a cooling tube cooled by a coolant, and a casing that houses the cooling tube.
玻璃纤维经过沿铅垂方向将冷却筒贯通的光纤通路，由此被冷却。
The glass fiber is cooled when passing through a fiber path that extends through the cooling tube in the vertical direction.
壳体和冷却筒之间的空间保持为比冷却筒的温度低的露点的干燥气氛，因此能够预先防止由水蒸气的凝结产生的微小的水滴附着于玻璃纤维(例如参照专利文献1的[0014]段)。
A space between the casing and the cooling tube is maintained under a dry atmosphere having a dew point lower than the temperature of the cooling tube.
专利文献1：日本特开平8－259254号公报
Therefore, small water drops due to the condensation of water vapor can be prevented from adhering to the glass fiber (see paragraph 0014 of Patent Document 1).
另外，在通常的拉丝装置中，玻璃纤维在拉丝炉和冷却装置之间暴露于外部气体。
In a typical drawing apparatus, a glass fiber is exposed to outside air between a drawing furnace and a cooling device.
如果不暴露于外部气体而从拉丝炉至冷却装置为止将玻璃纤维的通路与外部气体遮断，则热风从拉丝炉流入至冷却装置，通过冷却装置将玻璃纤维进行冷却的能力显著地降低
If a glass fiber path between the drawing furnace and the cooling device is shut off from outside air, and the glass fiber is not exposed to outside air, hot air would flow from the drawing furnace into the cooling device, causing the performance of cooling the glass fiber in the cooling device to be significantly decreased.
另一方面，如果暴露于外部气体，则在玻璃纤维被引入冷却装置的壳体的内部时，外部气体与玻璃纤维一起被吸入壳体的内部。
Conversely, if glass fiber is exposed to outside air, outside air would be carried along with the glass fiber into the casing when the glass fiber is drawn into the casing of the cooling device.
玻璃纤维的行进速度越快，外部气体越容易被吸入壳体的内部。
As the drawing speed of the glass fiber increases, outside air is more readily carried into the casing.
外部气体是包含水蒸气的空气，外部气体的露点高于冷却筒的温度。
Outside air is air containing water vapor, and the dew point of outside air is higher than the temperature of a cooling tube.
以往对壳体内的露点进行测定的位置不适当，超过根据露点的测定值设想的量的水蒸气被吸入光纤通路，由此有时在光纤通路中产生霜或者结露。
In the related-art, the formation of frost or condensation may occur because a dew point measurement position within a casing is not appropriate, and thus, the amount of water vapor, exceeding an amount expected from the measured dew point, is carried into the fiber path.
本发明的一个方式提供能够抑制冷却筒的光纤通路中产生霜或者水滴的技术。
According to an aspect of the present disclosure, a technology that reduces the formation of frost or water drops in a fiber path of a cooling tube is provided.
本发明的一个方式所涉及的光纤的制造方法，具有将从玻璃母材拉丝出的玻璃纤维在涂敷树脂前收容于壳体内，使其经过将由冷媒冷却的冷却筒贯通而形成的光纤通路的工序。
The glass fiber is drawn from a glass preform, the fiber path is formed through a cooling tube, and the cooling tube is housed in a casing and is cooled by a coolant.
所述工序包含向所述壳体和所述冷却筒之间的干燥空间导入露点比所述冷却筒的温度低的干燥气体。
The passing process includes supplying a dry gas into a dry space formed between the casing and the cooling tube.
所述工序包含通过露点仪对所述光纤通路的入口及出口中的至少1个的露点进行测定。
The passing process includes measuring, by a dew point meter, a second dew point at one or both of an inlet and an outlet of the fiber path.
所述工序包含对所述冷却筒的冷媒温度进行控制，以使得所述冷却筒的温度高于通过所述露点仪测定的所述露点。
The passing process includes controlling the temperature of the coolant in the cooling tube such that the temperature of the cooling tube is higher than the second dew point measured by the dew point meter.
根据本发明的一个方式，能够抑制冷却筒的光纤通路中产生霜或者水滴。

20 冷却装置
According to an aspect of the present disclosure, it is possible to reduce the formation of frost or water drops in a fiber path of a cooling tube.
21 冷却筒
First, embodiments of the present disclosure will be listed and described.
22 光纤通路
(1) According to an aspect of the present disclosure, an optical fiber manufacturing method includes a passing process, passing a glass fiber through a fiber path before applying a resin.
23 壳体
The glass fiber is drawn from a glass preform, the fiber path is formed through a cooling tube, and the cooling tube is housed in a casing and is cooled by a coolant.
24 干燥空间
The passing process includes supplying a dry gas into a dry space formed between the casing and the cooling tube.
31 温度调节器
The dry gas has a first dew point lower than the temperature of the cooling tube.
32 泵
The passing process includes measuring, by a dew point meter, a second dew point at one or both of an inlet and an outlet of the fiber path.
40 干燥气体供给装置
The passing process includes controlling the temperature of the coolant in the cooling tube such that the temperature of the cooling tube is higher than the second dew point measured by the dew point meter.
90 控制装置
The inventors of the present invention investigated the cause of the breakage of a glass fiber, and found that the breakage of the glass fiber occurs when a dew point measurement position within a casing is not appropriate, and thus, the amount of water vapor, exceeding an amount expected from the measured dew point, is carried into a fiber path.
[本发明的实施方式的说明]
In the related-art, a dew point measurement position (such as a point 101P indicated by a white circle in FIG. 1 ) is located beside a cooling tube and is far away from a glass fiber.
首先，列举本发明的实施方式而进行说明。
Therefore, the amount of water vapor, exceeding an amount expected from the measured dew point, may be carried into a fiber path.
〔1〕本发明的一个方式所涉及的光纤的制造方法具有将从玻璃母材拉丝出的玻璃纤维在涂敷树脂前收容于壳体内，使其经过将由冷媒冷却的冷却筒贯通而形成的光纤通路的工序。
This is because outside air in the vicinity of the glass fiber is carried along with the glass fiber into the fiber path.
所述工序包含向所述壳体和所述冷却筒之间的干燥空间导入露点比所述冷却筒的温度低的干燥气体。
With the above-described optical fiber manufacturing method according to (1), the dew point is measured at one or both of the inlet and the outlet of the fiber path by the dew point meter.
所述工序包含通过露点仪对所述光纤通路的入口及出口中的至少1个的露点进行测定。
Therefore, the dew point of gas carried along with the glass fiber into the fiber path can be measured.
所述工序包含对所述冷却筒的冷媒温度进行控制，以使得所述冷却筒的温度高于通过所述露点仪测定的所述露点。
In addition, the temperature of the coolant in the cooling tube is controlled such that the temperature of the cooling tube is higher than the dew point measured by the dew point meter, thereby reducing the formation of frost or condensation in the fiber path.
本发明涉及一种用于空气喷射式折边装置的折边头，该折边头具有狭缝，并且该空气喷射式折边装置利用来自折边喷嘴的空气喷射，将引入到狭缝的上下对置的狭缝表面之间的纬纱的端部进行折边。
The present invention relates to a tuck-in head for an air-injection type tuck-in device, wherein the tuck-in head has a slit, and the air-injection type tuck-in device is configured to tuck-in an end portion of a weft introduced between opposing upper and lower slit surfaces of the slit by air injected from a tuck-in nozzle.
众所周知，空气喷射式折边装置主要由折边头构成，并且用于通过从折边头上的折边喷嘴喷射的压缩空气，将引纬的纬纱的端部折回(折入)经纱的开口中。
As well known, an air-injection type tuck-in device is mainly constituted of a tuck-in head and is configured to fold back (tuck) an end portion of a weft-inserted weft into an opening of a warp by a compressed air injected from a tuck-in nozzle provided on a tuck-in head.
并且，折边头具有由上下对置的狭缝表面限定的狭缝，并且布置成靠近机织织物的织边，使得引纬的纬纱的端部随着打纬一起被引入到狭缝中。
Also, the tuck-in head has a slit defined by opposing upper and lower slit surfaces and is arranged near to a selvage of a woven fabric so that the end portion of the weft-inserted weft is introduced into the slit along with beating.
作为这样的空气喷射式折边装置(折边头)，例如，已知有专利文献1中公开的一种。
As such an air-injection type tuck-in device (tuck-in head), for example, one disclosed in PTL 1 is known.
另外，这样的空气喷射式折边装置(以下，简称为“折边装置”)具有将引入到狭缝中的纬纱的端部保持到进行折边为止的结构。
Additionally, such an air-injection type tuck-in device (hereinafter, simply referred to as a "tuck-in device") includes a configuration for holding the end portion of the weft, which has been introduced in the slit, until the tuck-in is performed.
对于专利文献1的折边装置，在折边头上形成在下部的狭缝面开口的保持孔(纬线端保持孔)和用于向保持孔喷射压缩空气的保持喷嘴(纬线端保持嘴)。
For the tuck-in device of PTL 1, a holding hole (weft end gripping hole), which opens in a lower slit surface, and a holding nozzle (weft end gripping nozzle), which is configured to inject a compressed air toward the holding hole, are formed on a tuck-in head.
另外，所述折边装置包括用于将如上所述的纬纱的端部带到折边喷嘴喷射压缩空气的位置的结构。
In addition, the tuck-in device includes a configuration for bringing the end portion of the weft, which is held as described above, to a position, on which a compressed air injected from a tuck-in nozzle is acted.
对于专利文献1的折边装置，在折边头上形成有纬纱释放喷嘴，该纬纱释放喷嘴用于在狭缝的底面中开口并喷射压缩空气。
For the tuck-in device of PTL 1, a weft release nozzle, which is configured to open in a bottom surface of the slit and to inject a compressed air, is formed on the tuck-in head.

PTL 1: Japanese Patent Application Publication No. 2011-111700
然而，对于一般的折边装置，折边头被制造为单个构件，并且其狭缝通过在该单个构件上进行诸如切割的机械加工而形成。
However, for general tuck-in devices, a tuck-in head is manufactured as a single member, and a slit thereof is formed by performing machining, such as cutting, on the single member.
而且，狭缝的上侧的和下侧的狭缝表面之间的距离非常小，例如约1mm。
Also, a distance between upper and lower slit surface of the slit is very small, for example about 1 mm.
同时，该狭缝表面的状态(表面粗糙度)可能影响折边是否成功。
Meanwhile, a state (surface roughness) of the slit surfaces is likely to influence whether or not tuck-in is successful.
因此，用于形成狭缝的加工必须以狭缝表面的状态不会对编织时的折边产生不利影响的程度进行。
Therefore, the machining for forming the slit has to be performed in such an extent that the state of the slit surfaces does not adversely influence tuck-in upon weaving.
然而，由于加工缺陷等原因，某些制造好的折边头可能在狭缝表面中具有不合适的表面粗糙度。
However, some of manufactured tuck-in heads are likely to have an improper surface roughness in slit surfaces due to machining defects or the like.
然而，如上所述，由于上侧的和下侧的狭缝表面之间的距离非常小，因此不能从外部识别出狭缝表面的状态。
However, since the distance between upper and lower slit surfaces is very small as described above, the state of the slit surfaces cannot be identified from the outside.
因此，这种折边头也会被安装在织机上或作为组件而出货。
As a result, such tuck-in heads are also shipped while being mounted on looms or as components.
同时，如果使用如上所述的狭缝表面的表面粗糙度不合适的折边头，则存在在编织(试验编织)时不能正常进行折边(以下称为“折边不良”)的情况经常发生的风险。
Meanwhile, if a tuck-in head, in which a surface roughness of slit surfaces is improper as described above, is employed, there is a risk that a case where tuck-in is not normally performed upon weaving (test weaving) (hereinafter, referred to as a "poor tuck-in") occurs frequently.
此外，如果该折边不良频繁发生，工人必须进行工作以查明原因。
Additionally, if the poor tuck-in occurs frequently, a worker has to perform work to identify what is the cause.
另外，如果发现该原因是切缝表面的状态，则工人必须在织造工厂中进行额外的加工，以使切缝表面的表面粗糙度达到合适程度。
In addition, if it is found that the cause is the state of the slit surfaces, the worker has to perform an additional machining in a weaving factory in order to bring the surface roughness of the slit surfaces to a proper extent.
而且，这样的工作对工人来说是繁重的。
Also, such works are burdensome for the worker.
另外，如上所述的附加加工必须由工人手动进行。
In addition, the additional machining as described above has to be manually performed by the worker.
所以，在某些情况下，不能使狭缝表面的表面粗糙度达到合适的程度，因此必须更换折边头。
Therefore, in some cases, the surface roughness of the slit surfaces cannot be brought to the proper extent, and thus the tuck-in head has to be replaced.
另外，如专利文献1中公开的折边头那样，在折边头上形成有保持孔的情况下，由于形成保持孔的机械加工，在保持孔开口的狭缝表面的一部分上可能会留下毛刺。
Also, in a case where a holding hole is formed in a tuck-in head as in the tuck-in head disclosed in PTL 1, a bur is likely to be left on a part of a slit surface, in which the holding hole opens, due to machining for forming the holding hole.
另外，如同狭缝表面的表面粗糙度不合适的情况一样，这种留下毛刺的状态也会导致不良折边的频繁发生。
In addition, like the case where the surface roughness of the slit surfaces is improper, such a state where a bur is left also causes the poor tuck-in to occur frequently.
因此，需要进行如上所述的作业或更换折边头。
Therefore, works or replacement of the tuck-in head as described above is required.
本发明是针对上述问题而提出的，并且本发明的目的是提供一种用于进行折边的空气喷射式折边装置的折边头，其中，狭缝表面的状态能够在折边头的制造步骤中识别。
The present invention has been made keeping in mind the above problems, and an object thereof is to provide a tuck-in head for an air-injection type tuck-in device configured to perform tuck-in, in which states of slit surfaces can be identified during a manufacturing step of the tuck-in head.
如上所述，本发明涉及一种用于空气喷射式折边装置的折边头，该折边头用于将纬纱的端部折入狭缝的上下对置的狭缝表面之间。
The present invention is directed to a tuck-in head for an air-injection type tuck-in device configured to tuck an end portion of a weft introduced between opposing upper and lower slit surfaces of a slit as described above.
而且，根据本发明的折边头包括：第一构件，构成包括上侧的狭缝表面的部分；以及第二构件，与第一构件分开形成，构成包括下侧的狭缝表面的部分。
Also, the tuck-in head according to the present invention includes a first member constituting a part including the upper slit surface; and a second member formed separately from the first member and constituting a part including the lower slit surface.
另外，该折边头至少组合第一构件和第二构件而构成。
In addition, the tuck-in head is constructed by combining at least the first member and the second member with each other.
而且，在根据本发明的折边头中，第一构件和第二构件中的至少一个可以形成为具有形成狭缝的底面的部分。
Also, in the tuck-in head according to the present invention, at least one of the first member and the second member may be formed to have a part forming a bottom surface of the slit.
此外，在该折边头中，可以在第一构件和第二构件中的至少一个形成凸部，并且可以在另一个形成与凸部嵌合的凹部。
Further, in the tuck-in head, a convex portion may be formed on at least one of the first member and the second member and a concave portion may be formed on the other, so that the convex portion is fitted in the concave portion.
另外，当组合第一构件和第二构件时，可以通过将凸部嵌合于凹部中来进行组合。
In addition, when combining the first member and the second member with each other, combining may be performed by fitting the convex portion into the concave portion.
根据本发明的折边头，折边头至少由第一构件和第二构件组合而成，所述第二构件与所述第一构件分开形成。
According to the tuck-in head of the present invention, the tuck-in head is constructed by combining at least the first member and the second member, which is formed separately from the first member.
而且，第一构件形成为包括狭缝的上侧的狭缝表面的构件，并且第二构件形成为包括狭缝的下侧的狭缝表面的构件。
Also, the first member is formed as a member including the upper slit surface of the slit, and the second member is formed as a member including the lower slit surface of the slit.
也就是说，第一和第二构件在其各自的表面被用作彼此相对的狭缝表面的状态下组合。
That is, the first and second members are combined in a state respective surfaces thereof functioning as slit surfaces oppose each other.
因此，每个构件中的狭缝表面是每个构件的表面的一部分，因此是暴露于外部的表面。
Therefore, the slit surface in each of the members is a part of a surface of each of the members and thus is a surface exposed to the outside.
换句话说，至少在折边头的制造步骤中将两个构件组合之前的阶段，能够识别每个构件的狭缝表面的状态。
In other words, a state of the slit surface of each of the member can be identified at least at a stage before two members are combined during a manufacturing step of the tuck-in head.
因此，在制造第一和第二构件中的每一个的过程中，可以在识别构成狭缝表面的表面状态的同时进行机械加工(精加工)。
Accordingly, during a process of manufacturing each of the first and second members, it is possible to perform machining (finishing) while identifying a state of a surface thereof constituting the slit surface.
因此，可以尽可能地防止狭缝表面的表面粗糙度不合适的两个构件被接受为成品。
Therefore, it is possible to prevent the two members, in which the slit surface has an improper surface roughness, from being accepted as a finished product as far as possible.
结果，在通过组合两个构件形成的折边头中，能够获得具有合适的表面粗糙度的狭缝表面。
As a result, the slit surfaces having a proper surface roughness can be obtained in the tuck-in head formed by combining the two members.
因此，可以基本上防止由于狭缝表面的不合适的表面粗糙度而引起的折边不良，并相应地可以促进减轻工人等的负担。
Therefore, it is possible to basically prevent a poor tuck-in caused due to an improper surface roughness of the slit surfaces and correspondingly to promote reduction in burdensome of a worker and the like.
而且，在根据本发明的折边头中，配置第一和第二构件使得第一和第二构件中的至少一个具有形成狭缝底面的部分，即使得折边头中的狭缝底面由与第一和/或第二构件的狭缝表面连续的表面形成。
Also, in the tuck-in head according to the present invention, the first and second members are configured such that at least one of the first and second members has a part forming the bottom surface of the slit, namely, such that the bottom surface of the slit in the tuck-in head is formed by a surface continuous to the slit surface of the first and/or second member.
因此，通过组合两个构件形成狭缝。
Accordingly, the slit is formed by combining the two members.
因此，可以仅通过第一和第二构件来构造折边头。
Therefore, it is possible to construct the tuck-in head by only the first and second members.
因此，由于这种结构，可以以更简单的结构实现本发明的折边头。
Thus, due to this configuration, it is possible to realize the tuck-in head of the present invention in a simpler configuration.
本发明涉及车辆用门支承装置。
The present invention relates to a vehicle door support device.
专利文献1中公开了一种支承部件，其被配置在车辆的车体和后尾门之间，向车门相对于车体打开的方向施力，将车门保持在开位置。
Patent Document 1 discloses a support member that is arranged between a vehicle body and a back door of a vehicle, biases the door so as to be open with respect to vehicle body, and holds the door at an open position.
支承部件具有外筒以及被可进退地容纳在外筒内的内筒，通过螺旋弹簧和气弹簧，向内筒相对于外筒进入的方向施力。
The support member has an outer cylinder and an inner cylinder accommodated in the outer cylinder so as to be capable of advancing and retracting, and the inner cylinder is biased by a coil spring and a gas spring so as to advance with respect to the cuter cylinder.
车门相对于车体开闭时，气弹簧兼具有防止车门急剧地开闭的功能。
The gas spring also has a function of preventing the door from being open and closed suddenly when the door is open and closed with respect to the vehicle body.

Patent Document 1: JP 2015-90212
气弹簧难以进行通过气体(氮气)和油的封入而确定的负载的微调整。
For the gas spring, it is difficult to finely adjust a load determined by charging a gas (nitrogen gas) and oil.
另外，气体受到温度或环境变化的影响，难以将负荷维支承为一定。
Since the gas is affected by changes in temperature and environment, it is difficult to maintain a constant load.
因此，专利文献1的支承部件存在改良的余地。
Therefore, there is room for improvement in the support member of Patent Literature 1.
本发明的课题在于提供一种车辆用门支承装置，其能够稳定地施加确定的负载，也易于进行负载大小的调整。
An object of the present invention is to provide a vehicle door support device that can stably apply a predetermined load and easily adjust the magnitude of the load.
本发明的一方案提供一种车辆用门支承装置，包括第一支承部件和第二支承部件，其分别具有被连接于车体的第一连接端和被连接于车门的第二连接端，将所述车门相对于所述车体保持在开位置，所述第一支承部件和第二支承部件分别包括：筒状的容纳部，具有构成所述第一连接端和所述第二连接端中一方的端部；筒状的盖部，与所述容纳部的所述端部相反的一侧相连；筒状的可动部件，具有构成所述第一连接端和所述第二连接端中另一方的端部，与该端部相反的一侧被容纳在所述盖部内，能够在轴向上能够与所述盖部相对性地移动；齿轮机构，被配置在所述容纳部内，具有位于所述盖部侧的第一连接部以及位于所述容纳部的所述端部侧的第二连接部，使所述第一连接部侧的旋转速度慢于所述第二连接部侧的旋转速度；主轴，被配置在所述可动部件内，被连接于所述第一连接部；旋转机构，通过所述可动部件相对于所述盖部的相对移动，使所述主轴旋转；以及螺旋弹簧，被配置在所述可动部件内，向使所述可动部件相对于所述盖部进入的方向施力，至少所述第一支承部件还包括磁阻机构，其被配置在所述容纳部内，被连接于所述第二连接部，经由所述齿轮机构向所述主轴施加负载。
Each of the first support member and the second support member'includes: a cylindrical accommodating portion that has an end portion forming one of the first connection end and the second connection end; a cylindrical cover that is connected to an opposite side of the end portion of the accommodating portion; a cylindrical movable member that has an end portion forming tie other of the first connection end and the second connection end, is accommodated in the cover on an opposite side of the end portion, and is movable relative to the cover in an axial direction; a gear mechanism that is arranged in the accommodating portion, has a first connecting portion located close to the cover and a second connecting portion located close to the end portion of the accommodating portion, and sets a rotational speed of the first connecting portion to be lower than a rotational speed of the second connecting portion; a spindle that is arranged in the movable member and connected to the first connecting portion; a rotation mechanism that rotates the spindle by movement of the movable member relative to the cover; and a coil spring that is arranged in the movable member and biases the movable member so as to advance with respect to the cover.

According to the vehicle door support device, the movable member is biased by the extension of the coil spring when the door is unlocked from the vehicle body, so that the movable member advances with respect to the cover while the spindle rotates via the rotation mechanism.
而且，通过螺旋弹簧的作用力，车门相对于车体被保持在开位置。
Then, the door is held at the open position with respect to the vehicle body by a biasing force of the coil spring.
