在本实施方式中，露点设为是在与干燥空间24的气压P1相同的气压下进行测定的。
In the present embodiment, the dew point is measured at the same air pressure as air pressure P 1 in the dry space 24.
本发明抑制在干燥空间24中产生霜或者结露。
This is because the present disclosure is intended to reduce the formation of frost or condensation in the dry space 24.
干燥空间24的气压P1如后面所述高于外部空间6的气压P0。
The air pressure P 1 in the dry space 24 is higher than air pressure P 0 in an external space 6, as will be described later.
外部空间6是指在壳体23的外部形成的空间。
The external space 6 is a space outside the casing 23.
外部空间6通常由空气占据。
Typically, the external space 6 is filled with air.
外部空间6的气压P0为大气压。
The air pressure P 0 in the external space 6 is atmospheric pressure.
此外，干燥空间24的气压P1和外部空间6的气压P0之间的压差ΔP1(ΔP1＝P1－P0)，通常小于或等于外部空间6的气压P0的1％。
The differential pressure ΔP 1 between the air pressure P 1 in the dry space 24 and the air pressure P 0 in the external space 6 (ΔP 1=P 1−P 0) is typically 1% or less of the air pressure P 0 in the external space 6.
因此，露点也可以在外部空间6的气压P0即大气压下进行测定。
Therefore, the dew point may be measured at the air pressure P 0 in the external space 6, namely at atmospheric pressure.
其原因在于，如果压差ΔP1小于或等于大气压的1％，则由压差ΔP1引起的露点的差小，是可以忽略的程度。
If the differential pressure ΔP 1 is 1% or less of atmospheric pressure, the difference in dew point caused by the differential pressure ΔP 1 is negligibly small.
另外，冷却筒21如上述那样，沿铅垂方向将多个配置为一列。
As described above, the plurality of cooling tubes 21 are arranged in a line in the vertical direction.

例如，有时在下侧配置的冷却筒21的温度被控制为低于在上侧配置的冷却筒21的温度。
For example, a cooling tube 21 located at the lower side may be controlled at a temperature lower than that of a cooling tube 21 located at the upper side.
在多个冷却筒21被控制为不同的温度的情况下，将比冷却筒21的最低温度低的露点的干燥气体导入至干燥空间24。
If the plurality of cooling tubes 21 are controlled at different temperatures, the dry gas having a dew point lower than the lowest temperature of a cooling tube 21 is supplied into the dry space 24.
壳体23在冷却筒21的周围保持干燥气体。

作为干燥气体，在本实施方式中如后面所述使用干燥空气，但也可以使用氮气等。
In the present embodiment, dry air is used as the dry gas; however, nitrogen gas may be used.
由于干燥气体的露点低于冷却筒21的温度，因此即使干燥气体被冷却，也能够抑制霜或者结露附着于冷却筒21，能够抑制由于霜或者结露而玻璃纤维3断线。
The dew point of the dry gas is lower than the temperature(s) of the cooling tubes 21.
此外，在冷却筒21的温度小于或等于0℃的情况下产生霜。
Accordingly, even if the dry gas is cooled, it is possible to prevent the formation of frost or condensation on the cooling tubes 21, and thus possible to prevent the breakage of the glass fiber 3 due to such frost or condensation.
在冷却筒21的温度超过0℃的情况下产生结露。
Note that frost occurs when the temperature(s) of the cooling tubes 21 are 0° C. or below, and condensation occurs when the temperature(s) of the cooling tubes 21 are above 0° C.
如上所述，干燥空间24的气压P1比外部空间6的气压P0稍高。
As described above, the air pressure P 1 in the dry space 24 is slightly higher than the air pressure P 0 in the external space 6.
通过其压差ΔP1，能够对外部气体从外部空间6向干燥空间24流入进行限制。
The differential pressure ΔP 1 enables the restriction of the flow of outside air from the external space 6 into the dry space 24.
通过对外部气体从外部空间6向干燥空间24的流入进行抑制，从而能够抑制水蒸气从外部空间6向干燥空间24流入，能够对霜或者结露附着于冷却筒21进行抑制。
By restricting the flow of outside air from the external space 6 into the dry space 24, it is possible to reduce the flow of water vapor from the external space 6 into the dry space 24, thereby reducing the formation of frost or condensation on the cooling tubes 21.

同时，在将折边头3安装在织机1上的状态下，表面10b是构成折边头3的上表面3b的一部分的表面，并且也是第一构件10的上表面。
Meanwhile, in a state where the tuck-in head 3 is installed on the loom 1, the surface 10b is a surface constituting a part of an upper surface 3b of the tuck-in head 3 and also becomes an upper surface of the first member 10.
而且，第二构件11类似为块状构件，并且当从正面观察其侧面11a时，形成为具有大致L形。
Also, the second member 11 is similarly a block-shaped member and is formed to have a substantially L-shape when viewing a side surface 11a thereof from a front side.
也就是说，第二构件11是块状构件，其侧面11a形成为大致L形。
That is, the second member 11 is a block-shaped member, of which the side surface 11a is formed in a substantially L-shape.
另外，侧面11a是构成折边头3的侧面3a的表面，其不包括第一构件10的侧面10a。
In addition, the side surface 11a is a surface constituting a surface of the side surface 3a of the tuck-in head 3, excluding the side surface 10a of the first member 10.
此外，第二构件11形成为使得其外围表面的两个表面11c、11d(不包括侧面11a)位于L形的内侧且彼此连续，并且彼此垂直。
Further, the second member 11 is formed such that two surfaces 11c, 11d of a peripheral surface thereof (excluding the side surface 11a), which is located on an inner side of the L-shape and also continuous to each other, is perpendicular to each other.
另外，为了形成折边头3，将第一构件10安装到第二构件11的两个表面11c、11d中的一个表面11c。
Also, in order to form the tuck-in head 3, the first member 10 is attached to one 11c of the two surfaces 11c, 11d of the second member 11.
也就是说，在第二构件11中，彼此垂直的两个表面中的一个表面11c成为被安装面。
That is, in the second member 11, one surface 11c of the two surfaces thereof perpendicular to each other becomes an attached surface.
另外，第二构件11的外围表面的表面11b与另一面11d相对，也与被安装面11c连续，形成为垂直于被安装面11c。
Also, a surface 11b of the peripheral surface of the second member 11, which is opposite to the other surface 11d and also continuous to the attached surface 11c, is formed to be perpendicular to the attached surface 11c.
同时，表面11b是除了第一构件10的上表面10b之外，构成折边头3的上表面3a的表面，并且还成为第二构件11的上表面。
Meanwhile, the surface 11b is a surface constituting a surface of the upper surface 3a of the tuck-in head 3, excluding the upper surface 10b of the first member 10, and also becomes an upper surface of the second member 11.
同时，对于被安装面11c，第二构件11形成为使得从两个表面11c、11d中的另一个表面11d沿其延伸方向测量的被安装面11c的尺寸，大于在垂直于第一构件10的上表面10b的方向上测量的安装面10e的尺寸。
Meanwhile, as for the attached surface 11c, the second member 11 is formed such that a dimension of the attached surface 11c, as measured from the other surface 11d of the two surfaces 11c, 11d in an extension direction thereof, is larger than a dimension of the attaching surface 10e, as measured in a direction perpendicular to the upper surface 10b of the first member 10.
但是，这种尺寸差被设置为等于折边头3的上侧的和下侧的狭缝表面4a、4b之间的一定距离(预定距离)。
But, such a difference in dimension is set to be equal to a certain distance (predetermined distance) between the upper and lower slit surfaces 4a, 4b of the tuck-in head 3.
另外，在折边头3中，在使第一构件10的安装面10e与第二构件11的被安装面11c安装的状态下，进行第一构件10与第二构件11的安装，但是，对于被安装面11c的延伸方向而言，是第一构件10的上表面10b的位置与第二构件11的上表面11b的位置重合的状态。
Additionally, in the tuck-in head 3, attaching of the first member 10 to the second member 11 is performed in a state where the attaching surface 10e of the first member 10 is brought to abut against the attached surface 11c of the second member 11, but in a state where, with respect to the extension direction of the attached surface 11c, a position of the upper surface 10b of the first member 10 coincides with a position of the upper surface 11b of the second member 11.
因此，在安装后，第一构件10的上表面10b与第二构件11的上表面11b齐平。
Therefore, after attaching, the upper surface 10b of the first member 10 is flush with the upper surface 11b of the second member 11.
而且，在安装之后，构成上侧的狭缝表面4a的第一构件10的表面10c布置成面对第二构件11的另一个表面11d，彼此平行并且彼此之间具有预定距离。
Also, after attaching, the surface 10c of the first member 10, which constitutes the upper slit surface 4a, is arranged to face the other surface 11d of the second member 11 in parallel to each other and with the predetermined distance interposed therebetween.
因此，第二构件11的另一个表面11d是构成下侧的狭缝表面4b的表面。
Therefore, the other surface 11d of the second member 11 is a surface constituting the lower slit surface 4b.
另外，第二构件11的外围表面中的表面11e与被安装面11c相对且与构成下侧的狭缝表面4b的面11d连续，表面11e的形成相对于构成下部狭缝表面4b的表面11d倾斜，从而形成导向面4e。
Further, the surface 11e of the peripheral surface of the second member 11, which is opposite to the attached surface 11c and also continuous to the surface 11d constituting the lower slit surface 4b, is formed to be inclined with respect to the surface 11d constituting the lower slit surface 4b, thereby forming the guide surface 4e.
而且，如上所述，通过将第一构件10安装至第二构件11，使得构成上侧的狭缝表面4a的表面10c和构成下侧的狭缝表面4b的表面11d以预定距离彼此相对，被安装面11c的一部分11c1(这一部分在其延伸方向上朝向构成下侧的狭缝表面4b的表面11d)暴露于两个狭缝表面4a、4b之间的空间。
Also, as described above, by attaching the first member 10 to the second member 11 such that the surface 10c constituting the upper slit surface 4a and the surface 11d constituting the lower slit surface 4b face each other with the predetermined distance interposed therebetween, a part 11c1 of the attached surface 11c (a part thereof located toward the surface 11d constituting the lower slit surface 4b in the extension direction thereof) is exposed to a space between two slit surfaces 4a, 4b.
另外，被安装面11c的暴露于该空间的部分11c1成为狭缝4的底面4c。
In addition, the part 11c1 of the attached surface 11c exposed to the space becomes the bottom surface 4c of the slit 4.
另外，在本实施方式的折边头3中，第一构件10具有在安装面10e上形成的突起12，并且第二构件11还具有在被安装面11c上形成的凹槽13，以允许凸起12嵌合在其中，从而容易地实现如上所述的安装状态。
Also, in the tuck-in head 3 of the present embodiment, the first member 10 has a protrusion 12 formed on the attaching surface 10e and also the second member 11 has a groove 13 formed in the attached surface 11c to allow the protrusion 12 to be fitted therein, thereby easily realizing the attached state as described above.
更具体地，第一构件10的安装面10e具有形成为在平行于侧表面10a和上表面10b的方向上突出的突起12。
More specifically, the attaching surface 10e of the first member 10 has the protrusion 12 formed to protrude in a direction parallel to the side surface 10a and the upper surface 10b.
另外，凸起12形成为在第一构件10的相对的侧面10a、10a之间，在与第一构件10的侧面10a垂直的方向(折边头3的宽度方向)上延伸。
In addition, the protrusion 12 is formed to extend between opposing side surfaces 10a, 10a of the first member 10 in a direction perpendicular to the side surfaces 10a of the first member 10 (in a width direction of the tuck-in head 3).
此外，突起12形成为在其延伸方向上具有大致正方形的形状。
Further, the protrusion 12 is formed to have a substantially square shape as viewed in an extension direction thereof.
另一方面，第二构件11的被安装面11c具有形成为允许第一构件10的突起12嵌合在其中的凹槽13。
On the other hand, the attached surface 11c of the second member 11 has the groove 13 formed to allow the protrusion 12 of the first member 10 to be fitted therein.
但是，在其中安装有突起12的状态下，凹槽13形成在如上所述的第一构件10的上表面10b和第二构件11的上表面11b彼此齐平的位置。
But, the groove 13 is formed at such a position that, in a state where the protrusion 12 is fitted therein, the upper surface 10b of the first member 10 and the upper surface 11b of the second member 11 are flush with each other as described above.
然后，当第一构件10被安装到第二构件11时，第一构件10的突起12被嵌合于第二构件11的凹槽13中。
Then, when the first member 10 is attached to the second member 11, the protrusion 12 of the first member 10 is fitted into the groove 13 of the second member 11.
因此，在如上所述第一构件10的上表面10b和第二构件11的上表面11b彼此齐平的状态下，组合第一构件10和第二构件11。
As a result, the first member 10 and the second member 11 are combined with each other in a state where the upper surface 10b of the first member 10 and the upper surface 11b of the second member 11 are flush with each other as described above.
因此，在本实施方式的折边头3中，突起12用作“凸部”，并且凹槽13用作“凹部”。
Therefore, in the tuck-in head 3 of the present embodiment, the protrusion 12 functions as a "convex portion" and the groove 13 functions as a "concave portion."
另外，如上所述，通过将第一构件10和第二构件11组合，上侧的狭缝表面4a和下侧的狭缝表面4b之间隔着预定的距离相对，并且，狭缝4由狭缝表面4a、4b和底面4c限定，底面4c由第二构件11的被安装面11c的部分11c1形成。
Also, as the first member 10 and the second member 11 are combined as described above, the upper slit surface 4a and the lower slit surface 4b face each other with the predetermined distance interposed therebetween, and also the slit 4 is defined by both slit surfaces 4a, 4b and the bottom surface 4c, which is formed by the part 11c1 of the attached surface 11c of the second member 11.
而且，根据本实施例，在如上所述的第一构件10和第二构件11的组合状态下，该组合状态的固定通过螺钉构件14进行。
Also, according to the present embodiment, in the combined state of the first member 10 and the second member 11 as described above, fixation of the combined state is performed by a screw member 14.
因此，折边头3包括螺钉构件14和允许螺钉构件14插入其中并拧入其中的孔。
For this reason, the tuck-in head 3 includes the screw member 14 and holes allowing the screw member 14 to be inserted therethrough and screwed therein.
更具体地，第二构件11具有插入孔15，该插入孔15形成为在被安装面11c上的位置的开口，该位置比凹槽13更靠近上表面11b，并且还沿着垂直于被安装面11c的方向延伸穿过第二构件11。
More specifically, the second member 11 has an insertion hole 15 formed to open at a location on the attached surface 11c, which is located more toward the upper surface 11b than the groove 13, and also to extend through the second member 11 in a direction perpendicular to the attached surface 11c.
另一方面，第一构件10具有形成为在安装面10e中开口的内螺纹孔16。
On the other hand, the first member 10 has a female threaded hole 16 formed to open in the attaching surface 10e.
同时，当如上所述将第一构件10和第二构件11组合时，内螺纹孔16形成在使得内螺纹孔16能够与第二构件11的插入孔15连通的位置。
Meanwhile, the female threaded hole 16 is formed at such a position that, when the first member 10 and the second member 11 are combined as described above, the female threaded hole 16 can be communicated with the insertion hole 15 of the second member 11.
然后，当如上所述以组合状态将第一构件10和第二构件11彼此固定时，螺钉构件14从第二构件11的与被安装面11c相反的一侧，从第二构件11的插入孔15插入；然后，将螺钉构件14拧入第一构件10的内螺纹孔16中。
Then, when the first member 10 and the second member 11 are fixed to each other in the combined state as described above, the screw member 14 is inserted through the insertion hole 15 of the second member 11 from the side thereof opposite to the attached surface 11c, and then the screw member 14 is screwed into the female threaded hole 16 of the first member 10.
因此，如上所述的第一构件10和第二构件11的组合状态被固定，从而形成了折边头3。
As a result, the combined state of the first member 10 and the second member 11 as described above is fixed, thereby forming the tuck-in head 3.
另一方面，在本实施方式中，除了利用螺钉构件14的固定(螺钉固定)以外，还通过利用粘合剂的粘合来进行固定。
On the other hand, in the present embodiment, the fixation is achieved by adhesion using adhesive, in addition to fixation using the screw member 14 (screw fixation).
也就是说，根据本实施方式的折边头3，通过在安装面10e上涂胶，将第一构件10和第二构件11粘接并固定，从而补充螺钉固定。
That is, according to the tuck-in head 3 of the present embodiment, the first member 10 and the second member 11 are adhered and fixed to each other by adhesive applied on the attaching surface 10e, thereby complementing the screw fixation.
但是，如果仅通过螺钉固定就可以实现稳定的固定状态，则可以省略这种粘合固定。
But, if a stably fixed state is achieved only by the screw fixation, such an adhesion fixation may be omitted.
相反，如果仅通过粘附固定就可以实现稳定的固定状态，则可以省略螺钉固定。
In contrast, if the stably fixed state is achieved only by the adhesion fixation, the screw fixation may be omitted.
而且，根据本发明的折边式头，用于保持第一构件10和第二构件11的组合状态的装置不限于螺钉固定或粘合固定，因此，可以采用任何其他配置。
Also, according to the tuck-in head of the present invention, a means for holding the combined state of the first member 10 and the second member 11 is not limited to the screw fixation or the adhesion fixation, and accordingly any other configurations may be employed.
而且，根据如上所述构造的折边头3，构成折边头3的第一构件10和第二构件11在制造折边头3的步骤中被分开加工(形成)。
Also, according to the tuck-in head 3 configured as described above, the first member 10 and the second member 11 constituting the tuck-in head 3 are separately machined (formed) during a step of manufacturing the tuck-in head 3.
因此，能够进行折边头3中的分别构成上侧的、下侧的狭缝面4a、4b的构件10、11的表面10c、11d的加工，同时能够容易地识别该表面的状态。
Therefore, machining of the surfaces 10c, 11d of the members 10, 11 constituting the upper and lower slit surfaces 4a, 4b, respectively, of the tuck-in head 3 can be performed while states of the surfaces can be easily identified.
因此，尽可能地防止了构件10、11的表面10c、11d的表面粗糙度不适合狭缝表面。
As a result, the surfaces 10c, 11d of the members 10, 11 are prevented from being finished while having a surface roughness, which is improper as the slit surface, as far as possible.
因此，在制造步骤中，能够完成折边头3，使得狭缝表面4a，4b具有适当的表面粗糙度。
Therefore, during the manufacturing step, the tuck-in head 3 can be finished such that the slit surfaces 4a, 4b have a proper surface roughness.
此外，根据本实施例的折边头3，折边头3仅由第一构件10和第二构件11两个构成，并且为了实现该目的，折边头3被配置为使得第二构件11的被安装面11c的部分11c1构成狭缝4的底面4c。
Further, according to the tuck-in head 3 of the present embodiment, the tuck-in head 3 is constituted of only two first and second members 10, 11, and also in order to enable this, the tuck-in head 3 is configured such that the part 11c1 of the attached surface 11c of the second member 11 constitutes the bottom surface 4c of the slit 4.
一对突出部分中一方构成被机械性地连接于第二连接部45B的第一轴部54b。

The magnet 55A is a portion that generates an S-pole magnetic force, and the magnet 55B is a portion that generates an N-pole magnetic force.
它们被形成为扇形，在芯材53的外表面向周向交替配置，作为整体形成圆筒状。
The magnet 55A and the magnet 55B are formed in a fan shape, are alternately arranged in the circumferential direction on the outer surface of the core material 53, and have a cylindrical shape as a whole.
在轴部件54的轴向上，磁铁55A、55B的尺寸与芯材53的尺寸相同。
In the axial direction of the shaft member 54, dimensions of the magnets 55A and 55B are the same as the dimension of the core material 53.
固定部件57是能够以轴部件54的轴线为中心围住磁铁55A、55B(旋转部件52)的圆筒部件。
The fixed member 57 is a cylindrical member that can surround the magnets 55A and 55B (rotating member 52) about the axis of the shaft member 54.
也就是说，固定部件57的内径大于旋转部件52的外径，在其之间形成有确定间隔(例如0.5mm)的间隙。
That is, an inner diameter of the fixed member 57 is larger than an outer diameter of the rotating member 52, and a gap having a predetermined interval (for example, 0.5 mm) is formed between the fixed member 57 and the rotating member 52.
固定部件57的轴向上的尺寸大于磁铁55A、55B的尺寸。
An axial dimension of the fixed member 57 is larger than the dimensions of the magnets 55A and 55B.
更具体而言，设定固定部件57的轴向上的尺寸，以使固定部件57的一端触碰间隔件60的分隔壁60g，固定部件57的另一端触碰齿轮机构44的端面。
More specifically, the axial dimension of the fixed member 57 is set such that one end of the fixed member 57 abuts on a partition wall 60 gof the spacer 60 and the other end of the fixed member 57 abuts on an end face of the gear mechanism 44.
由此，固定部件57被夹持在分隔壁60g和齿轮机构44之间。
As a result, the fixed member 57 is sandwiched between the partition wall 60 gand the gear mechanism 44.
如图6所最清楚地示出，为了限制以轴部件54为中心的固定部件57的旋转，在固定部件57的一端设置有切口部57a，间隔件60的凸部60i卡止于该切口部57a。
As illustrated most clearly in FIG. 6, a notch 57 ais provided at one end of the fixed member 57, and a convex portion 60 iof the spacer 60 is locked into the notch 57 ain order to restrict the rotation of the fixed member 57 about the shaft member 54.
通过由磁铁55A、55B的磁力而容易被磁化、容易消磁的磁性材料(例如铝镍钴磁铁(Al-Ni-Co磁铁))形成固定部件57。
The fixed member 57 is formed using a magnetic material (for example, an alnico magnet (Al—Ni—Co magnet)) that is easily magnetized by the magnetic forces of the magnets 55A and 55B and is easily demagnetized.
如图7所示，在固定部件57中，与磁铁55A(S极)对置的部分58A被磁化为N极，与磁铁55B(N极)对置的部分58B被磁化为S极。
As illustrated in FIG. 7, in the fixed member 57, a portion 58A opposing the magnet 55A (S pole) is magnetized to the N pole, and a portion 58B opposing the magnet 55B (N pole) is magnetized to the S pole.
即，在固定部件57中，在周向上交替形成被磁化为N极的部分58A和被磁化为S极的部分58B。
That is, the portion 58A magnetized to the N pole and the portion 58B magnetized to the S pole are alternately formed in the fixed member 57 in the circumferential direction.
在旋转部件52旋转的朝向上，在磁铁55A(S极)的前侧形成有被磁化为S极的部分58B，在磁铁55B(N极)的前侧形成有被磁化为N极的部分58A。
In the direction in which the rotating member 52 rotates, the portion 58B magnetized to the S pole is formed on the front side of the magnet 55A (S pole), and the portion 58A magnetized to the N pole is formed on the front side of the magnet 55B (N pole).
同极性的磁铁55A、55B和磁化部分58B、58A彼此相斥，从而成为旋转部件52旋转的阻力。
The magnets 55A and 55B and the magnetized portions 58B and 58A having the same polarity repel each other, and thus, form a resistance of the rotation of the rotating member 52 Therefore, a load can be applied to the spindle 34 via the gear mechanism 44.
磁阻机构50的磁阻小于打开车门3时经由旋转机构37使主轴34旋转的螺旋弹簧32的作用力、以及关闭车门3时经由旋转机构37使主轴34旋转的车门3的按压力。
The magnetic resistance by the magnetoresistive mechanism 50 is smaller than the biasing force of the coil spring 32 to rotate the spindle 34 via the rotation mechanism 37 at the time of opening the door 3 and a pressing force of the door 3 to rotate the spindle 34 via the rotation mechanism 37 at the time of closing the door 3.
因此，在车门3的开闭时，主轴34克服磁阻机构50的阻力而旋转，旋转部件52经由齿轮机构44而从动旋转。
Therefore, when the door 3 is open and closed, the spindle 34 rotates against the resistance of the magnetoresistive mechanism 50, and the rotating member 52 is driven to rotate via the gear mechanism 44.
通过磁铁55A、55B的起磁力以及磁铁55A、55B的轴向上的尺寸(全长)的变更等调整(设定)磁阻机构50的磁阻。
The magnetic resistance of the magnetoresistive mechanism 50 is adjusted (set) by changing magnetizing forces of the magnets 55A and 55B and the axial dimensions (total length) of the magnets 55A and 55B.
通过旋转部件52的旋转来改变磁铁55A、55B的旋转角度位置，当磁铁55B(N极)位于被磁化为N极的部分58A的内侧时，磁化部分58A被消磁，成为重新被磁化为S极的部分58B。
When the magnet 55B (N pole) is located inside the portion 58A magnetized to the N pole due to changes of rotation angle positions of the magnets 55A and 55B along with the rotation of the rotating member 52, the magnetized portion 58A is demagnetized and becomes the portion 58B newly magnetized to the S pole.
另外，磁铁55A(S极)位于被磁化为S极的部分58B的内侧时，磁化部分58B被消磁，成为重新被磁化为N极的部分58A。
When the magnet 55A (S pole) is located inside the portion 58B magnetized to the S pole, the magnetized portion 58B is demagnetized and becomes the portion 58A newly magnetized to the N pole.
即，固定部件57的内表面侧根据位于内侧的磁铁55A、55B而反复被磁化和消磁。
That is, the magnetization and demagnetization are repeated on the inner surface side of the fixed member 57 according to the magnets 55A and 55B located inside.
因此，可以稳定地对主轴34持续施加确定的负载。
Therefore, it is possible to continue applying a predetermined load stably to the spindle 34.
如图2及图6所示，间隔件60是包括支承齿轮机构44的第一端60a以及经由减震器66B及护环68A支承轴端部件23A的第二端60b的圆筒状的部件。
As illustrated in FIGS. 2 and 6, the spacer 60 is a cylindrical member including: a first end 60 athat supports the gear mechanism 44; and a second end 60 bthat supports the shaft end member 23A via the damper 66B and the grommet 68A.
间隔件60的内径与固定部件57的外径大致相同，间隔件60的外径小于容纳部21的内径。
An inner diameter of the spacer 60 is substantially the same as an outer diameter of the fixed member 57, and a outer diameter of the spacer 60 is smaller than the inner diameter of the accommodating portion 21.
