Description
本發明主要是有關於作為如無線機器的攜帶型電子機器的旋轉型開關和可變電阻器使用的旋轉操作型電子零件的軸承構造。 The present invention relates to a bearing structure of a rotary operation type electronic component used as a rotary switch and a variable resistor of a portable electronic device such as a wireless device.
習知,在旋轉型開關和可變電阻器等採用的軸承構造是例如日本專利第4759071號和日本實開昭62-168607號所示只是將軸***軸承的構造。因此未設成減少軸的推力方向和徑向方向的遊動的構成,遊動是依據軸承及軸的尺寸精度被決定。 Conventionally, a bearing structure used in a rotary switch, a variable resistor, or the like is a structure in which a shaft is inserted into a bearing as shown in, for example, Japanese Patent No. 4759071 and Japanese Laid-Open No. 62-168607. Therefore, the configuration in which the thrust in the thrust direction and the radial direction of the shaft is reduced is not provided, and the movement is determined in accordance with the dimensional accuracy of the bearing and the shaft.

This bearing structure can suppress the movement in the radial direction, but the movement in the axial direction cannot be suppressed.
攜帶型電子機器的旋轉型開關雖被要求小型化,但其操作旋鈕的尺寸仍使用可滿足操作容易性程度者。因此,旋鈕操作位置中的軸遊動會藉由旋鈕的大小而增大,在旋鈕操作時無法給與操作者平順的感觸。 Although the rotary switch of the portable electronic device is required to be miniaturized, the size of the operation knob is still used to satisfy the ease of operation. Therefore, the movement of the shaft in the operation position of the knob is increased by the size of the knob, and the operator is not able to feel smooth during the operation of the knob.
本發明是鑑於上述的問題,其目的是提供一種旋轉操作型電子零件的軸承構造,可以抑制軸方向及徑向方向的 遊動。 The present invention has been made in view of the above problems, and an object thereof is to provide a bearing structure of a rotary operation type electronic component capable of suppressing an axial direction and a radial direction. Swimming.

The annular groove is provided with a fixing ring, and the rotating operation shaft is stopped by being engaged with the other end of the bearing.
或是將上述錐面形成於轉動操作部及保持部間的階段部,在軸孔的內周緣形成內徑被擴大的承接溝,在承接溝及錐面之間將彈性環彈性地挾持的構造。 Or, the tapered surface is formed in a step portion between the rotational operation portion and the holding portion, and a receiving groove having an enlarged inner diameter is formed on the inner peripheral edge of the shaft hole, and the elastic ring is elastically held between the receiving groove and the tapered surface. .
在本發明中,對於形成階段部的角部,藉由錐面將彈性環按壓的外力因為會朝在軸方向及半徑方向被分配,所以可以抑制軸方向及半徑方向的遊動。 In the present invention, since the external force for pressing the elastic ring by the tapered surface is distributed to the corner portion forming the step portion in the axial direction and the radial direction, the movement in the axial direction and the radial direction can be suppressed.
在第1圖顯示適用本發明的軸承構造的旋轉型開關的 實施例的分解立體圖,其軸方向剖面圖如第2圖所示。 Fig. 1 shows a rotary switch to which the bearing structure of the present invention is applied An exploded perspective view of the embodiment is shown in Fig. 2 in the axial direction.
此旋轉型開關是具有:圓柱狀的轉動操作軸10、及該轉動操作軸10***通的軸承20、及被裝設固定在轉動操作軸10並被轉動的旋轉件7、及支架6。 This rotary type switch has a cylindrical rotary operation shaft 10, a bearing 20 through which the rotary operation shaft 10 is inserted, a rotary member 7 attached to the rotary operation shaft 10 and rotated, and a bracket 6.
轉動操作軸10是由樹脂或金屬形成,同軸地設有:具有與軸方向平行地被倒角加工的外周面的圓柱狀的操作部11、及從操作部11的一端使徑變小地朝軸方向延長的圓柱狀的保持部12、及從保持部12的一端使徑進一步變小地朝軸方向延長的圓柱狀的驅動部13。操作部11的保持部12側端面及保持部12的外周面是垂直交叉,形成階段部10S。在鄰接於保持部12的操作部11相反側的端面的外周形成有環狀溝12a。驅動部13的兩側是挾持軸中心線地施加與軸方向平行的平面加工,因此與軸中心線直角的剖面是形成四邊形,且其相面對的2邊是圓弧的形狀。 The rotary operation shaft 10 is formed of a resin or a metal, and is coaxially provided with a cylindrical operation portion 11 having an outer peripheral surface chamfered in parallel with the axial direction, and a smaller diameter from the one end of the operation portion 11 The cylindrical holding portion 12 having an axial direction extending and a cylindrical driving portion 13 extending in the axial direction from the one end of the holding portion 12 are further reduced in diameter. The end surface of the operation portion 11 on the side of the holding portion 12 and the outer circumferential surface of the holding portion 12 are perpendicularly intersected to form a step portion 10S. An annular groove 12a is formed on the outer circumference of the end surface on the opposite side of the operation portion 11 adjacent to the holding portion 12. Both sides of the driving portion 13 are formed by plane machining parallel to the axial direction of the center line of the clamping axis. Therefore, the cross section at right angles to the center line of the shaft is formed in a quadrangular shape, and the two sides facing each other are in the shape of a circular arc.
軸承20是由樹脂或是金屬形成,設有:具有比轉動操作軸10的操作部11的外徑小的內徑且具有保持部12插通的軸孔24的圓筒部21、及一體形成於圓筒部21的一端的幾乎直方體的外殼部22。在圓筒部21的外周面中形成有供旋轉型開關安裝在機器框體用的螺紋。在圓筒部21的先端部且在軸孔24的內周緣較佳是形成內徑對於軸方向朝向軸孔24外漸大45°的錐面20T。在外殼部22中形成有與軸孔24連通且與軸孔24同心且比其徑更大的圓形的收容凹部23,且朝圓筒部21的相反側的面被開放。 The bearing 20 is formed of a resin or a metal, and is provided with a cylindrical portion 21 having an inner diameter smaller than the outer diameter of the operation portion 11 of the rotary operation shaft 10 and having the shaft hole 24 through which the holding portion 12 is inserted, and integrally formed. The outer shell portion 22 of the almost rectangular body at one end of the cylindrical portion 21. A screw for attaching the rotary switch to the machine casing is formed on the outer peripheral surface of the cylindrical portion 21. At the tip end portion of the cylindrical portion 21 and at the inner peripheral edge of the shaft hole 24, a tapered surface 20T whose inner diameter is gradually increased by 45° toward the axial direction of the shaft hole 24 is preferably formed. A circular housing recess 23 that communicates with the shaft hole 24 and is concentric with the shaft hole 24 and has a larger diameter is formed in the outer casing portion 22, and a surface facing the opposite side of the cylindrical portion 21 is opened.
內徑是與保持部12的外徑幾乎相等,外徑是比轉動 操作軸10的操作部11的外徑小,使由橡膠材形成的剖面為圓形的彈性環3由與轉動操作軸10的階段部10S對接的方式被裝設於保持部12,保持部12插通軸承20的軸孔24,在其狀態下,朝收容凹部23內突出的保持部12的端部的環狀溝12a外徑是比軸孔24的內徑大,嵌合有環被切斷的彈性金屬的固定環4,卡合與軸孔24相鄰接的收容凹部23的底面23a使轉動操作軸10被止脫。此時,在階段部10S及錐面20T間被挾持的彈性環3是藉由錐面20T朝向階段部10S及保持部12的外周面的交叉的角彈性地被按壓而變形。朝轉動操作軸10給與軸方向及/或半徑方向的外力的話,彈性環3會進一步變形由其彈力抵抗外力。由此,轉動操作軸10的對於軸承20的軸方向及半徑方向的遊動被彈性地抑制。因此,操作者可獲得平滑的轉動操作感。彈性環3的材料,可以使用具有潤滑性的氟樹脂和矽樹脂等。 The inner diameter is almost equal to the outer diameter of the holding portion 12, and the outer diameter is a ratio of rotation The outer diameter of the operation portion 11 of the operation shaft 10 is small, and the elastic ring 3 having a circular cross section formed of a rubber material is attached to the holding portion 12 so as to be in contact with the step portion 10S of the rotary operation shaft 10, and the holding portion 12 is provided. In the state in which the shaft hole 24 of the bearing 20 is inserted, the outer diameter of the annular groove 12a of the end portion of the holding portion 12 projecting into the housing recess 23 is larger than the inner diameter of the shaft hole 24, and the ring is cut. The broken elastic metal retaining ring 4 engages the bottom surface 23a of the receiving recess 23 adjacent to the shaft hole 24 to cause the rotational operation shaft 10 to be stopped. At this time, the elastic ring 3 held between the step portion 10S and the tapered surface 20T is elastically pressed by the angle at which the tapered surface 20T intersects the outer peripheral surface of the step portion 10S and the holding portion 12 and is deformed. When the external force is applied to the rotational operation shaft 10 in the axial direction and/or the radial direction, the elastic ring 3 is further deformed by its elastic force against the external force. Thereby, the movement of the rotational operation shaft 10 with respect to the axial direction and the radial direction of the bearing 20 is elastically suppressed. Therefore, the operator can obtain a smooth rotational operation feeling. As the material of the elastic ring 3, a fluororesin having a lubricity, a enamel resin, or the like can be used.

Further, two positioning projections 63 adjacent to one side from which the terminals 6T1, 6T2, and 6T3 are led are formed.
上側支架60,是與:3個彈性接觸件6C1、6C2、6C3、及從那些一體地延長且從上側支架60的一側面朝外突出的端子6T1、6T2、6T3一起由嵌入成型形成。3個彈性接觸件6C1、6C2、6C3是從窗61的緣朝內側延伸,那 些的先端是各別位於被限定在旋轉件70的滑動接觸片7C的環狀帶B1、B2、B3上。在此例中各彈性接觸件6C1、6C2、6C3是各別具有2個分岐腕,與各環狀帶2點接觸。 The upper bracket 60 is formed by insert molding together with three elastic contacts 6C1, 6C2, and 6C3, and terminals 6T1, 6T2, and 6T3 which are integrally extended and protrude outward from one side of the upper bracket 60. The three elastic contact members 6C1, 6C2, and 6C3 extend from the edge of the window 61 toward the inner side, that The leading ends are each located on the endless belts B1, B2, B3 defined by the sliding contact piece 7C of the rotary member 70. In this example, each of the elastic contact members 6C1, 6C2, and 6C3 has two branching arms, and is in contact with each of the endless belts at two points.
返回至第9圖,下側支架80的定位突起83(第14圖A參照)是與棘爪彈簧支撐板50的定位孔53b嵌合,使下側支架80被定位固定在棘爪彈簧支撐板50上。從其上,將旋轉件70的碟片部72的幾乎下半部配置在下側支架80的旋轉件收容凹部82內的方式,將轉動操作軸10的驅動部13插通旋轉件70的軸孔73,且將轉動軸71的下端部通過棘爪彈簧支撐板50的軸孔51並***卡合於棘爪圓板30的軸孔33。 Returning to Fig. 9, the positioning projection 83 of the lower bracket 80 (refer to Fig. 14A) is fitted to the positioning hole 53b of the pawl spring supporting plate 50, so that the lower bracket 80 is positioned and fixed to the pawl spring supporting plate. 50 on. From the above, the drive portion 13 of the rotary operation shaft 10 is inserted into the shaft hole of the rotary member 70 so that the substantially lower half of the disc portion 72 of the rotary member 70 is disposed in the rotary member housing recess 82 of the lower bracket 80. 73, and the lower end portion of the rotating shaft 71 is passed through the shaft hole 51 of the pawl spring supporting plate 50 and inserted into the shaft hole 33 of the pawl disk 30.
將其旋轉件70的碟片部72的幾乎上一半收容在上側支架60的旋轉件收容凹部62的方式,從旋轉件70的上被覆上側支架60,並重疊固定在下側支架80。此時上側支架60的卡合凸部65及卡合凹部66(第14圖B參照)是各別嵌合在下側支架80的卡合凹部86及卡合凸部85,彼此被定位。進一步,在蓋90的軸孔91將旋轉件70的轉動軸71的上端部***並從上側支架60上將蓋90重疊將定位突起94嵌合在定位孔64b,將定位突起63嵌合在定位孔93b。由此下側支架80的彈性接觸件8C1、8C2、8C3是與旋轉件70的碟片部72的下面彈性地接觸維持,上側支架60的彈性接觸件6C1、6C2、6C3是與旋轉件70的碟片部72的上面彈性地接觸維持。 The upper bracket 60 is covered from the upper side of the rotor 70 so that almost the upper half of the disc portion 72 of the rotor 70 is housed in the rotor housing recess 62 of the upper bracket 60, and is superposed and fixed to the lower bracket 80. At this time, the engagement convex portion 65 and the engagement concave portion 66 (refer to FIG. 14B) of the upper bracket 60 are the engagement concave portions 86 and the engagement convex portions 85 that are fitted to the lower bracket 80, respectively, and are positioned. Further, the upper end portion of the rotating shaft 71 of the rotary member 70 is inserted into the shaft hole 91 of the cover 90, and the cover 90 is overlapped from the upper bracket 60 to fit the positioning projection 94 to the positioning hole 64b, and the positioning projection 63 is fitted in the positioning. Hole 93b. Thereby, the elastic contacts 8C1, 8C2, 8C3 of the lower bracket 80 are maintained in elastic contact with the lower surface of the disc portion 72 of the rotary member 70, and the elastic contact members 6C1, 6C2, 6C3 of the upper bracket 60 are coupled to the rotary member 70. The upper surface of the disc portion 72 is elastically contact-maintained.
在如此將零件在合體的狀態下,將2條的固定銷8插通:蓋90的固定孔93a、上側支架60的固定孔64a、下側支架80的固定孔84a、棘爪彈簧支撐板50的固定孔53a、軸承20的固定孔22a,將銷8的先端由鉚釘壓潰,彼此固定成一體。 In this state, the two fixing pins 8 are inserted in the state in which the components are combined: the fixing hole 93a of the cover 90, the fixing hole 64a of the upper bracket 60, the fixing hole 84a of the lower bracket 80, and the pawl spring supporting plate 50. The fixing hole 53a and the fixing hole 22a of the bearing 20 crush the tip end of the pin 8 by rivets and are integrally fixed to each other.
藉由如此組裝旋轉型開關,驅動部13,是插通已插通棘爪圓板30、棘爪彈簧支撐板50的旋轉件70的轉動軸71的軸孔73,被支撐於蓋90的軸孔91內。與旋轉件70的軸孔73的軸心直角的剖面是與驅動部13的剖面相同的方式形成將圓的弧由直線切除的形狀,因此,藉由轉動操作軸10的轉動使旋轉件70被轉動並且使棘爪圓板30也被轉動。其結果,被固定於棘爪彈簧支撐板50的棘爪彈簧40的突起41是與轉動的棘爪圓板30的放射狀凹凸卡合當轉動操作軸10的轉動操作時會產生喀嗒感,且,在旋轉件70的上側及下側面的接觸片7C1、7C2、及上側及下側支架的彈性接觸件6C1、6C2、6C3及8C1、8C2、8C3之間會滑動接觸,就可以產生分離。 By assembling the rotary switch in this manner, the drive portion 13 is a shaft hole 73 through which the rotation shaft 71 of the rotary member 70 of the pawl disc 30 and the pawl spring support plate 50 is inserted, and is supported by the shaft of the cover 90. Inside the hole 91. The cross section at right angles to the axial center of the shaft hole 73 of the rotary member 70 is formed in the same manner as the cross section of the drive portion 13 to form a shape in which the arc of the circle is cut by a straight line, and therefore, the rotary member 70 is rotated by the rotation of the rotary operation shaft 10 Rotate and cause the pawl disc 30 to also be rotated. As a result, the projection 41 of the click spring 40 fixed to the pawl spring support plate 50 is engaged with the radial unevenness of the rotating pawl disk 30, and when the rotational operation shaft 10 is rotated, a click feeling is generated. Further, separation can be caused by sliding contact between the contact pieces 7C1 and 7C2 on the upper and lower sides of the rotary member 70 and the elastic contact members 6C1, 6C2, 6C3 and 8C1, 8C2, and 8C3 of the upper and lower holders.
從以上的說明可理解,在此第3實施例中因為可以在旋轉件70的碟片部的上側面及下側面且在半徑方向各別不同的環狀領域各別決定在360°內接觸片領域,所以具有設計自由度較高的優點。即,可以讓複數開關的開閉的角度範圍、相對時間點對應要求設計的自由度提高。 As can be understood from the above description, in the third embodiment, the contact piece can be determined within 360° in the annular region in which the upper and lower sides of the disc portion of the rotary member 70 are different in the radial direction. The field has the advantage of high design freedom. In other words, the angle range of the opening and closing of the plurality of switches and the relative time point can be increased in accordance with the degree of freedom required for design.
在上述的第3實施例中,雖顯示對於旋轉件70的上側及下側面的接觸片7C1、7C2共通地限定環狀帶B1、 B2、B3的情況,但是將環狀帶的數量、及寬度對於上側及下側各別限定,將上側支架60及下側支架80的彈性接觸件的數、及配置各別配合於側的環狀帶決定可以也當然。 In the third embodiment described above, it is shown that the contact strips 7C1, 7C2 on the upper side and the lower side of the rotary member 70 collectively define the endless belt B1. In the case of B2 and B3, the number and width of the endless belt are limited to the upper side and the lower side, and the number of the elastic contacts of the upper bracket 60 and the lower bracket 80 and the ring that is disposed on the side are arranged. The belt decision can be of course.
第15圖是顯示本發明的旋轉型開關的第4實施例。在前述的第3實施例中,將下側支架80與彈性接觸件8C1、8C2、8C3一起藉由嵌入成型一體形成之後,因為在窗81內將彈性接觸件8C1、8C2、8C3朝所期的角度曲折,所以下側支架80及棘爪彈簧支撐板50是別體形成,但是在將彈性接觸件8C1、8C2、8C3彎曲成預先預定的角度的狀態下可以將下側支架80嵌入成型的情況時,如第15圖所示形成下側支架80及棘爪彈簧支撐板50彼此一體的下側支架(第1支架)80'也可以。同樣地,第3實施例中的上側支架60及蓋90也如第15圖所示形成彼此一體的上側支架(第2支架)60'也可以。其他的構成因為是與第3實施例同樣所以省略說明。 Fig. 15 is a view showing a fourth embodiment of the rotary switch of the present invention. In the foregoing third embodiment, the lower bracket 80 and the elastic contact members 8C1, 8C2, and 8C3 are integrally formed by insert molding, because the elastic contact members 8C1, 8C2, and 8C3 are intended to be in the window 81. The angle bracket is folded, and the lower side bracket 80 and the pawl spring support plate 50 are formed separately, but the lower bracket 80 can be insert molded in a state where the elastic contact members 8C1, 8C2, and 8C3 are bent at a predetermined angle. At the same time, as shown in Fig. 15, a lower bracket (first bracket) 80' in which the lower bracket 80 and the pawl spring support plate 50 are integrated with each other may be formed. Similarly, the upper bracket 60 and the cover 90 in the third embodiment may be formed as an upper bracket (second bracket) 60' which is integrated with each other as shown in Fig. 15. Since the other configurations are the same as those of the third embodiment, the description thereof is omitted.
第16圖A是將適用本發明的軸承構造的前述的各種實施例及變形例概念化顯示說明用的旋轉操作型電子零件的構成圖。圓柱狀的轉動操作軸100是具有:接受轉動操作的操作部110、及比操作部110徑小並同軸地延長的保 持部120、及從保持部120進一步使外徑變小並同軸地延長的驅動部130,操作部130及保持部120的交界是形成階段部110S。保持部120是從軸承200的一端側可轉動自如地***通軸承的軸孔230,被固定於保持部120的後端部外周上的固定環400是在軸承200的另一端與軸孔230的外周緣卡合。從保持部120延長突出的驅動部130是將設在軸承200的另一端的電機訊號控制部600內的旋轉件700轉動。電機訊號控制部600是包含:藉由旋轉件700的轉動,使產生由接觸件及電阻體之間的滑動所產生的電阻變化的可變電阻機構、或進行由彈性接觸件及接觸滑動片間的接觸、脫離所產生的開關動作的旋轉型開關機構,藉由電機的控制控制朝端子6T給與的訊號。 Fig. 16 is a configuration diagram of a rotary operation type electronic component for conceptually showing and explaining various embodiments and modifications of the bearing structure to which the present invention is applied. The cylindrical rotary operating shaft 100 has an operation portion 110 that receives a turning operation, and a smaller diameter and a coaxial extension than the operating portion 110. The holding portion 120 and the driving portion 130 that further reduces the outer diameter from the holding portion 120 and are coaxially extended, the boundary between the operation portion 130 and the holding portion 120 is the formation step portion 110S. The holding portion 120 is a shaft hole 230 that is rotatably inserted into the bearing from one end side of the bearing 200, and the fixing ring 400 fixed to the outer periphery of the rear end portion of the holding portion 120 is at the other end of the bearing 200 and the shaft hole 230. The outer circumference of the card is engaged. The drive unit 130 that is extended from the holding portion 120 rotates the rotary member 700 provided in the motor signal control unit 600 provided at the other end of the bearing 200. The motor signal control unit 600 includes a variable resistance mechanism that generates a change in resistance caused by sliding between the contact member and the resistor body by the rotation of the rotary member 700, or between the elastic contact member and the contact sliding sheet. The rotary switch mechanism that contacts and disengages the generated switching operation controls the signal applied to the terminal 6T by the control of the motor.
電機訊號控制部600是該當包含:第1及4圖的實施例中的支架6、6'、及旋轉件7、7'、及收容其的外殼部22的構成,第9、15圖的實施例是該當包含被收容於上側支架80、80'、下側支架60、60'、那些之間的旋轉件70的構成。 The motor signal control unit 600 includes the brackets 6 and 6', the rotors 7 and 7', and the outer casing 22 that accommodates the casings 22 in the first and fourth embodiments, and the implementation of the ninth and fifteenth embodiments. For example, the configuration includes the rotary member 70 housed between the upper brackets 80, 80' and the lower brackets 60, 60'.
本發明的軸承構造,是作成藉由使徑朝向形成於與轉動操作軸100的階段部100S相面對的軸承的軸孔的端部內周緣的外側變大的錐面200T將彈性環300按壓在階段部100S的構成。在此,階段部100S的面及保持部120的外周面是直角地交叉,錐面200T是對於保持部120的外周面由45°交叉。錐面200T及階段部100S及保持部外周面在軸方向剖面與形成直角二等邊三角形內接的圓的半徑 r,是r=L/2tan67.5°。但是,L是前述剖面中的直角二等邊三角形的斜邊的長度(以下稱為錐面的長度)。因此,彈性環300因為是藉由對於轉動操作軸100的軸方向及/或半徑方向的外力而受到彈性變形,所以有需要r>L/2tan67.5°。且,錐面的長度L是若階段部100S的半徑方向長度為D的話,D>Lsin45°。 In the bearing structure of the present invention, the elastic ring 300 is pressed by the tapered surface 200T which is formed to be larger toward the outer side of the inner peripheral edge of the end portion of the shaft hole of the bearing facing the step portion 100S of the rotational operation shaft 100. The configuration of the stage unit 100S. Here, the surface of the step portion 100S and the outer peripheral surface of the holding portion 120 intersect at right angles, and the tapered surface 200T intersects with the outer peripheral surface of the holding portion 120 by 45°. The radius of a circle in which the tapered surface 200T, the step portion 100S, and the outer peripheral surface of the holding portion are inscribed in the axial direction and which is formed by a right-angled equilateral triangle r, is r = L / 2 tan 67.5 °. However, L is the length of the oblique side of the right-angled equilateral triangle in the cross section (hereinafter referred to as the length of the tapered surface). Therefore, since the elastic ring 300 is elastically deformed by an external force in the axial direction and/or the radial direction of the rotational operation shaft 100, it is necessary that r>L/2tan67.5°. Further, the length L of the tapered surface is D>Lsin45° when the length of the step portion 100S in the radial direction is D.
錐面200T是顯示45°的情況時,藉由改變傾斜角度就可以改變從錐面200T朝彈性環300被給與的應力分配至軸方向成分及半徑方向成分的比率。 When the tapered surface 200T is 45°, the ratio of the stress applied from the tapered surface 200T to the elastic ring 300 to the axial direction component and the radial direction component can be changed by changing the inclination angle.
第16圖A的變形,如第16圖B所示,由將裝設在形成於軸孔230端部的內周緣的內徑變大的承接溝200G的彈性環300形成階段部100S的錐面100T進行按壓的構成。其他是與第16圖A同樣。 In the modification of Fig. 16A, as shown in Fig. 16B, the tapered surface of the step portion 100S is formed by the elastic ring 300 of the receiving groove 200G which is provided in the inner peripheral edge of the inner peripheral edge of the shaft hole 230. 100T is pressed to form. The other is the same as Fig. 16A.
