用以實施發明之形態 Forms for carrying out the invention

以下，根據圖式來具體說明本發明之實施形態。而，以下實施形態為將本發明具體化時的其中一形態，並非將本發明限定於該範圍內者。 Hereinafter, embodiments of the present invention will be specifically described based on the drawings. However, the following embodiments are one of the embodiments when embodying the present invention, and do not limit the present invention within this range.

圖1是顯示作為本發明實施形態之文具(筆具)的自動鉛筆1之構成的剖面圖，圖2是顯示自動鉛筆1之前方部分的剖面圖。在以下實施形態的說明中，將自動鉛筆1之軸管12的長方向所延伸的中心軸線簡稱為軸線，而其延伸方向則簡稱為軸線方向。又，將進行書寫之前端側稱為軸線方向之前方，相反側則稱為後方。 FIG. 1 is a cross-sectional view showing the configuration of a mechanical pencil 1 as a stationery (writing tool) according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a front part of the mechanical pencil 1. In the description of the following embodiments, the central axis extending in the longitudinal direction of the shaft tube 12 of the mechanical pencil 1 is simply referred to as the axis, and the extending direction thereof is simply referred to as the axis direction. In addition, the side before the writing is called the front in the axial direction, and the opposite side is called the rear.

自動鉛筆1包含：有大致圓錐狀外形的前方具11、大致圓筒狀的軸管12、大致圓筒狀而作為握部的握持部13、配置於後端部的按壓構件18以及筆夾19。 The mechanical pencil 1 includes a front tool 11 having a substantially conical shape, a substantially cylindrical shaft tube 12, a substantially cylindrical grip 13 as a grip, a pressing member 18 disposed at the rear end, and a pen holder 19.

又，自動鉛筆1之內部機構包含：可放入筆芯的筆芯管、可夾持及送出筆芯的夾頭部單元、以及用以使夾頭部單元作動的彈性構件。自動鉛筆1的內部機構可為習知的任意內部機構，因此省略其說明。又，其他文具(筆具) 之實施形態中，內部機構亦可為原子筆等其他任意文具(筆具)之內部機構。又，其他化粧品之實施形態中，內部機構可為收容有任意化桩料之化粧品容器的內部機構。 In addition, the internal mechanism of the mechanical pencil 1 includes a refill tube that can be put in a refill, a collet head unit that can hold and send out the pen core, and an elastic member for actuating the collet head unit. The internal mechanism of the mechanical pencil 1 may be any conventional internal mechanism, so its description is omitted. In addition, in other embodiments of the stationery (pen implements), the internal mechanism may also be an internal mechanism of any other stationery (pen implement) such as a ball pen. In addition, in other cosmetic embodiments, the internal mechanism may be an internal mechanism of a cosmetic container containing an arbitrary pile.

前方具11為具有大致圓錐狀外形的尖細筒狀構件。前方具11的前端部形成有開口，可供筆芯2或保持筆芯2之前端管21貫通。 The front tool 11 is a tapered cylindrical member having a substantially conical shape. The front end portion of the front tool 11 is formed with an opening for allowing the pen core 2 or the front end tube 21 for holding the pen core 2 to penetrate.

在前方具11之內周面上形成有母螺紋112(參考圖3)，可與軸管12之前端部的外周面上所形成的公螺紋1231螺合，藉由該等之螺合，前方具11可組裝於軸管12。 A female thread 112 (refer to FIG. 3) is formed on the inner peripheral surface of the front tool 11 and can be screwed with a male thread 1231 formed on the outer peripheral surface of the front end of the shaft tube 12. By such screwing, the front The tool 11 can be assembled to the shaft tube 12.

前方具11具有突出部111，從其大致圓錐狀之外形的底面(後面)115(參考圖3)朝後方突出。突出部111呈圓筒狀，具有較前方具11之後面115的外徑小的外徑，可***至後述握持部13前端的內周面所形成的埋頭孔131內部。 The front tool 11 has a protruding portion 111, and protrudes rearward from its substantially conical outer surface (rear surface) 115 (refer to FIG. 3). The protruding portion 111 has a cylindrical shape, has an outer diameter smaller than the outer diameter of the front surface 115 of the front tool 11, and can be inserted into the countersunk hole 131 formed in the inner peripheral surface of the front end of the grip portion 13 to be described later.

軸管12呈大致圓筒狀。在軸管12的前部形成可組合後述握持部13的握持部插通部121。握持部插通部121之外徑較軸管12的其他部分的外徑小。握持部插通部121後端之外徑是與握持部13之內徑大致相同或略小於握持部13之內徑。藉此，在握持部插通部121之後端，握持部13與軸管12(握持部插通部121)之間不會產生間隙。 The shaft tube 12 has a substantially cylindrical shape. A grip portion insertion portion 121 that can be combined with a grip portion 13 described later is formed on the front portion of the shaft tube 12. The outer diameter of the grip portion insertion portion 121 is smaller than the outer diameters of other parts of the shaft tube 12. The outer diameter of the rear end of the grip portion insertion portion 121 is substantially the same as or slightly smaller than the inner diameter of the grip portion 13. Thereby, no gap occurs between the grip portion 13 and the shaft tube 12 (grip portion insertion portion 121) at the rear end of the grip portion insertion portion 121.

握持部插通部121之外周面呈越朝後方其外徑越大。換言之，握持部插通部121之外周面呈尖細形狀。若如此構成，當將握持部13組裝於軸管之握持部插通部121的外周時，握持部插通部121前部的握持部13與握持部插通部121之間可形成越朝後方越小的空間15(間隙)。這點在握持部13前端之內周面上形成的埋頭孔131與握持部插通部121之間亦同，埋頭孔131與握持部插通部121之間可形成越朝後方越小的空間。故，當將後述之O環14朝空間15內之後方壓入時，越朝後方可越使O環14與握持部13及軸管12(握持部插通部121)兩者緊密接觸。在握持部插通部121之前方側形成朝徑方向外側突出之環狀突起122。環狀突起122之外徑略小於前方具之突出部111之內徑，當於軸管12組裝前方具11時，可將環狀突起122***突出部111之內側。藉由於軸管12形成突起122，可防止後述之O環14及握持部13朝軸管12之前方脱落。 The outer peripheral surface of the grip portion insertion portion 121 has a larger outer diameter toward the rear. In other words, the outer peripheral surface of the grip portion insertion portion 121 has a tapered shape. With this configuration, when the grip portion 13 is assembled on the outer periphery of the grip portion insertion portion 121 of the shaft tube, between the grip portion 13 and the grip portion insertion portion 121 in front of the grip portion insertion portion 121 A space 15 (gap) that becomes smaller toward the rear can be formed. This is the same between the countersunk hole 131 and the grip insertion portion 121 formed on the inner peripheral surface of the front end of the grip 13, and the countersunk hole 131 and the grip insertion portion 121 can be formed to be smaller toward the rear Space. Therefore, when the O ring 14 to be described later is pressed into the space 15 to the rear, the closer the O ring 14 is to the grip portion 13 and the shaft tube 12 (grip portion insertion portion 121), the closer to the rear. . An annular protrusion 122 protruding outward in the radial direction is formed on the front side of the grip portion insertion portion 121. The outer diameter of the annular protrusion 122 is slightly smaller than the inner diameter of the protrusion 111 of the front tool. When the front tool 11 is assembled to the shaft tube 12, the annular protrusion 122 can be inserted into the inner side of the protrusion 111. The projection 122 formed by the shaft tube 12 prevents the O-ring 14 and the grip portion 13 described later from falling toward the front of the shaft tube 12.

在軸管12之握持部插通部121外周，組裝呈圓筒狀而作為握部的握持部13。握持部13之素材與形成軸管12之素材不同，而與軸管12分別形成。本實施形態中，握持部13是由實質上不會彈性變形的素材形成。若如此構成，當軸管是由例如樹脂等可彈性變形之彈性率較低的素材形成時，亦可藉由握持部之觸感來獲得如同由例如彈性率較高的金屬素材所形成的自動鉛筆般提升的觸感。所謂「實質上不會彈性變形的素材」，是指具有一不會因自動鉛筆1一般組合及使用時附加於握持部13之外力而使握持部13彈性變形之剛性的素材。再者，握持部13是由硬度較形成軸管12之素材高的素材形成。若如此構成，即使軸管是由例如樹脂等較軟之素材形成時，亦可藉由握持部之觸感來獲得如同由較高硬度的金屬素材所形成的自動鉛筆般提升的觸感。再者，握持部13是由熱傳導率較形成軸管12之素材高的素材形成。若如此構成，即使軸管由例如樹脂等熱傳導率較低的素材形成時，亦可藉由握持部之觸感來獲得如同例如熱傳導率較高之金屬素材所形成的自動鉛筆般提升的觸感。本實施形態中，握持部13是由填充了金屬填充物的樹脂材料形成。而，其他實施形態中，可在由例如樹脂、木材等比重較小的材料所形成的軸管，組裝比重較構成軸管的材料大，例如金屬、玻璃、陶瓷等材料所形成的握持部。當如此使用比重較軸管之材料大的材料所形成的握持部時，可賦予自動鉛筆重量而獲得提升之重量感。 On the outer periphery of the grip portion insertion portion 121 of the shaft tube 12, a grip portion 13 that is cylindrical and serves as a grip portion is assembled. The material of the grip 13 is different from the material forming the shaft tube 12 and is formed separately from the shaft tube 12. In this embodiment, the grip 13 is formed of a material that does not substantially elastically deform. If constructed in this way, when the shaft tube is formed of a material with a low elastic modulus such as a resin that can be elastically deformed, it can also be obtained by, for example, a metal material with a high elastic modulus by the feel of the grip portion A touch of enhanced pencil. The “material that does not substantially elastically deform” means a rigid material that does not elastically deform the grip portion 13 due to the general combination of the mechanical pencil 1 and the external force added to the grip portion 13 during use. Furthermore, the grip 13 is formed of a material having a higher hardness than the material forming the shaft tube 12. With this configuration, even when the shaft tube is formed of a soft material such as resin, the touch feeling of the grip portion can be improved as if it were a mechanical pencil formed of a metal material with a higher hardness. Furthermore, the grip 13 is formed of a material having a higher thermal conductivity than the material forming the shaft tube 12. With this configuration, even when the shaft tube is formed of a material having a low thermal conductivity such as resin, the touch of the grip portion can be used to obtain a touch like a mechanical pencil formed from a metal material having a high thermal conductivity. sense. In this embodiment, the grip 13 is formed of a resin material filled with a metal filler. However, in other embodiments, a shaft portion formed of a material having a small specific gravity such as resin or wood may be assembled with a larger specific gravity than a material constituting the shaft tube, such as a metal, glass, ceramic, or other material. . When the grip portion formed of a material having a larger specific gravity than the material of the shaft tube is used in this way, the mechanical pencil can be given a weight and an increased sense of weight can be obtained.

在握持部13前端的徑方向內側形成環狀的埋頭孔131(參考圖3)。在握持部13形成環狀埋頭孔131，並如後所述使O環14被前方具11之突出部111朝後方壓迫，藉此在前方具之突出部111的後端面116(參考圖3)與握持部13之環狀埋頭孔131的底面(後端面)136(參考圖3)之間會壓縮O環14而使其於徑方向上彈性變形。當O環14於徑方向上彈性變形，O環14會與軸管12及握持部13兩者更緊密接觸，防止握持部13朝相對軸管12之軸線方向前方移動。埋頭孔131之深度(軸線方向之長度)構造成較O環14之剖面之圓形直徑d(O環14之軸線方向長度)來得深。若如此構成，如後所述，當O環14組裝於軸管12，可將以握持部13從徑方向外側覆蓋O環14之外周而組裝的O環14加以隱藏。故，不僅作為設計十分優秀，且可防止因自動鉛筆1之使用者的使用而使組裝好的握持部13從軸管12鬆脫。握持部13之外周面可具有溝加工等任意止滑形狀。 An annular countersunk hole 131 is formed radially inward of the front end of the grip 13 (refer to FIG. 3 ). An annular countersunk hole 131 is formed in the grip portion 13, and the O-ring 14 is pressed backward by the protrusion 111 of the front tool 11 as described later, whereby the rear end surface 116 of the protrusion 111 of the front tool (refer to FIG. 3) Between the bottom surface (rear end surface) 136 (refer to FIG. 3) of the annular countersunk hole 131 of the grip portion 13, the O-ring 14 is compressed to elastically deform in the radial direction. When the O-ring 14 is elastically deformed in the radial direction, the O-ring 14 will come into closer contact with both the shaft tube 12 and the grip portion 13 to prevent the grip portion 13 from moving forward relative to the axis of the shaft tube 12. The depth (the length in the axial direction) of the countersunk hole 131 is configured to be deeper than the circular diameter d (the length in the axial direction of the O ring 14) of the cross section of the O ring 14. According to this structure, as will be described later, when the O-ring 14 is assembled to the shaft tube 12, the O-ring 14 assembled by covering the outer circumference of the O-ring 14 from the outside in the radial direction can be hidden. Therefore, it is not only excellent in design, but also prevents the assembled grip 13 from being loosened from the shaft tube 12 due to the use of the user of the mechanical pencil 1. The outer peripheral surface of the grip portion 13 may have any anti-slip shape such as groove processing.

在軸管12與握持部13之間配置由彈性體形成而剖面為圓形環狀的O環14。O環14是配置成與軸管12及握持部13兩者接觸，而可防止握持部13相對於軸管12朝軸線方向移動。藉由配置O環14，特別是在將前方具11從軸管12取下時，亦可防止握持部13相對於軸管12前方移動而朝前方脫落或朝與軸線方向正交的方向移動。又，藉由將O環14配置成與軸管12及握持部13兩者接觸，可防止握持部13相對於軸管12朝周方向旋轉。再者，在握持部13已組裝於軸管12之狀態下，當因使用者之書寫而朝與軸線方向正交之方向施加外力時，可防止給予使用者一種握持部13相對於軸管12朝與軸線方向正交之方向移動的感觸。O環14是由具有彈性之材料形成，在本實施形態中是以彈性體材料形成。O環14之內徑D1與握持部插通部121之前端部(突起122之後方附近)的外徑大致相同或略小。 An O-ring 14 formed of an elastic body and having a circular cross section is arranged between the shaft tube 12 and the grip portion 13. The O-ring 14 is arranged to be in contact with both the shaft tube 12 and the grip portion 13 to prevent the grip portion 13 from moving in the axial direction relative to the shaft tube 12. By arranging the O-ring 14, especially when the front tool 11 is removed from the shaft tube 12, the grip portion 13 can be prevented from moving forward relative to the shaft tube 12 and falling off to the front or moving in the direction orthogonal to the axis direction . In addition, by arranging the O ring 14 to be in contact with both the shaft tube 12 and the grip portion 13, the grip portion 13 can be prevented from rotating in the circumferential direction relative to the shaft tube 12. Furthermore, in a state where the grip portion 13 has been assembled to the shaft tube 12, when an external force is applied in a direction orthogonal to the axis direction due to the user's writing, it is possible to prevent the user from being given a grip portion 13 relative to the shaft tube 12 The feeling of moving in the direction orthogonal to the axis direction. The O ring 14 is formed of a material having elasticity, and in this embodiment is formed of an elastomer material. The inner diameter D1 of the O-ring 14 is approximately the same as or slightly smaller than the outer diameter of the front end of the grip portion insertion portion 121 (near the rear of the protrusion 122).

參考圖3及圖4，進一步說明前方具11、軸管12、握持部13、O環14之組合、組合後之各構件相互關係。圖3是將自動鉛筆1之前方部分加以分解並顯示的剖面圖，圖4是將自動鉛筆1之前方部分構成加以擴大並顯示的剖面圖。自動鉛筆1之內部機構省略圖示。 With reference to FIGS. 3 and 4, the combination of the front tool 11, the axle tube 12, the grip portion 13, and the O-ring 14 will be further described, and the relationship between the components after the combination. FIG. 3 is a cross-sectional view in which the front part of the mechanical pencil 1 is exploded and displayed, and FIG. 4 is a cross-sectional view in which the front part of the mechanical pencil 1 is enlarged and displayed. The internal mechanism of the mechanical pencil 1 is not shown.

如圖3所示，將軸管12之前端部(握持部插通部121及環狀突起122)***圓筒狀握持部13之中心孔內並使其貫通。握持部插通部121及環狀突起122之外徑較握持部13之中心孔內徑小。故，要將握持部13組裝於軸管12是很容易的。 As shown in FIG. 3, the front end portion of the shaft tube 12 (the grip portion insertion portion 121 and the annular protrusion 122) is inserted into the central hole of the cylindrical grip portion 13 and penetrated. The outer diameters of the grip portion insertion portion 121 and the annular protrusion 122 are smaller than the inner diameter of the center hole of the grip portion 13. Therefore, it is easy to assemble the grip 13 to the shaft tube 12.

將握持部13組裝於軸管12後，將O環14從前方***並組裝於軸管12與握持部13之間的空間15內。首先，將O環14組裝於軸管12之握持部插通部121之前端部的外周面上。將由彈性體形成之O環14的中心孔朝徑方向外側擴大並使握持部插通部121前方所形成之軸管12之突起122的徑方向外側朝後方通過後，使O環14復原為原本之形狀並安裝於握持部插通部121之外周面上。在該狀態下，O環14可組裝於握持部13之前端面135前方之軸管的握持部插通部121之外周面上。 After assembling the grip portion 13 in the shaft tube 12, the O-ring 14 is inserted from the front and assembled in the space 15 between the shaft tube 12 and the grip portion 13. First, the O-ring 14 is assembled on the outer peripheral surface of the front end portion of the grip portion insertion portion 121 of the shaft tube 12. After the center hole of the O-ring 14 formed of an elastic body is expanded radially outward and the radial outer side of the protrusion 122 of the shaft tube 12 formed in front of the gripping portion insertion portion 121 is passed rearward, the O-ring 14 is restored to The original shape is attached to the outer peripheral surface of the grip portion insertion portion 121. In this state, the O-ring 14 can be assembled on the outer peripheral surface of the grip portion insertion portion 121 of the shaft tube in front of the front end surface 135 of the grip portion 13.

將O環14組裝於軸管12之握持部插通部121之外周面上後，使前方具11螺合於軸管12之前端部並組裝。當前方具11螺合於軸管12並組裝後，前方具11後端之突出部111可***軸管之握持部插通部121與握持部13 之埋頭孔131之間的空間15內。藉此，組裝於軸管12之握持部插通部121前端部的O環14會被突出部111朝後方壓迫，而壓入軸管12之握持部插通部121與握持部13之埋頭孔131之間的空間15內。如前所述，由於呈尖細狀之軸管12之握持部插通部121與握持部13之間的空間15越朝後方越窄，因此O環14越往後方移動，O環14會與軸管12及握持部13兩者緊密接觸。再者，在前方具11之突出部111後端與握持部13之埋頭孔131底面(後端面)之間於軸線方向上被壓縮之O環14，會朝徑方向內側及外側彈性變形而與軸管12及握持部13兩者更緊密接觸。本實施形態之O環14，其剖面之圓形直徑d是大於突起122之突出高度(從握持部插通部121之外周面朝徑方向外側之突出量)。又，呈環狀之突出部111的內徑D3至少小於O環14之外徑D2。若如此構成，組裝好的O環14會與軸管12及握持部13兩者更良好地接觸。O環14剖面之圓形直徑d以例如突起122之突出高度的2倍以上為佳。依據本實施形態之自動鉛筆1構成，藉由將前方具11螺合於軸管12之前端部並安裝的簡單組裝作業，可輕易且正確地將握持部13與O環14安裝於軸管12之預定位置。又，O環14不僅會與軸管12接觸，且也會與組裝於軸管12之前方具11接觸，因此可防止螺合於軸管12之前方具11相對於軸管12旋轉。故，可防止組裝好的前方具11與軸管12之螺合鬆脫而使前方具11從軸管12脫落。 After assembling the O-ring 14 on the outer peripheral surface of the grip portion insertion portion 121 of the shaft tube 12, the front tool 11 is screwed to the front end of the shaft tube 12 and assembled. After the front tool 11 is screwed into the shaft tube 12 and assembled, the protrusion 111 at the rear end of the front tool 11 can be inserted into the space 15 between the grip portion insertion portion 121 of the shaft tube and the countersunk hole 131 of the grip portion 13 . As a result, the O-ring 14 assembled at the front end of the grip portion insertion portion 121 of the shaft tube 12 is pressed backward by the protruding portion 111, and is pressed into the grip portion insertion portion 121 and the grip portion 13 of the shaft tube 12 In the space 15 between the countersunk holes 131. As described above, since the space 15 between the grip portion insertion portion 121 and the grip portion 13 of the tapered shaft tube 12 is narrower toward the rear, the O ring 14 moves backward, and the O ring 14 It will come into close contact with both the shaft tube 12 and the grip 13. Furthermore, the O-ring 14 compressed in the axial direction between the rear end of the protruding portion 111 of the front tool 11 and the bottom surface (rear end surface) of the countersunk hole 131 of the grip portion 13 is elastically deformed radially inward and outward. It is in closer contact with both the shaft tube 12 and the grip 13. In the O ring 14 of the present embodiment, the circular diameter d of the cross section is larger than the protrusion height of the protrusion 122 (the amount of protrusion from the outer peripheral surface of the grip portion insertion portion 121 toward the radially outer side). In addition, the inner diameter D3 of the annular protrusion 111 is at least smaller than the outer diameter D2 of the O-ring 14. With such a configuration, the assembled O-ring 14 will be in better contact with both the shaft tube 12 and the grip 13. For example, the circular diameter d of the cross section of the O ring 14 is preferably at least twice the height of the protrusion 122. According to the configuration of the mechanical pencil 1 of the present embodiment, by a simple assembly operation of screwing the front tool 11 to the front end of the shaft tube 12 and installing it, the grip portion 13 and the O ring 14 can be easily and correctly installed on the shaft tube 12 predetermined locations. In addition, the O-ring 14 not only contacts the shaft tube 12, but also contacts the jig 11 before assembling the shaft tube 12, so that the jig 11 before screwing on the shaft tube 12 can be prevented from rotating relative to the shaft tube 12. Therefore, the assembled front tool 11 and the shaft tube 12 can be prevented from being loosened and the front tool 11 can be detached from the shaft tube 12.

圖4是將前方具11已組裝於軸管12之狀態下的自動鉛筆1前方部分之構成加以擴大顯示之圖。又，圖5是將配置有O環14之部分加以擴大顯示之剖面圖。 FIG. 4 is an enlarged view of the structure of the front part of the mechanical pencil 1 in a state where the front tool 11 has been assembled to the shaft tube 12. In addition, FIG. 5 is a cross-sectional view showing an enlarged view of a portion where the O ring 14 is arranged.

如圖4及圖5所示，在前方具11已組裝於軸管12之狀態下，前方具11之圓錐狀外形之底面(後面)115與握持部13之前端面135會抵接。藉此，前方具 11會將握持部13朝後方壓迫。 As shown in FIGS. 4 and 5, in a state where the front tool 11 has been assembled to the shaft tube 12, the bottom surface (rear surface) 115 of the conical shape of the front tool 11 abuts the front end surface 135 of the grip 13. As a result, the front tool 11 presses the grip 13 toward the rear.

當O環14***軸管12(握持部插通部121)與握持部13(埋頭孔131)之間的空間15內時，O環14會在軸管12與握持部13之間於徑方向上被壓縮。由於軸管12與握持部13之間的間隔小於O環14之剖面圓形的直徑d，因此O環14會與軸管12及握持部13接觸而將握持部13卡止於軸管12之軸線方向上的預定位置。 When the O ring 14 is inserted into the space 15 between the shaft tube 12 (grip part insertion part 121) and the grip part 13 (counterbore hole 131), the O ring 14 will be between the shaft tube 12 and the grip part 13 It is compressed in the radial direction. Since the distance between the shaft tube 12 and the grip portion 13 is smaller than the diameter d of the circular cross section of the O ring 14, the O ring 14 will contact the shaft tube 12 and the grip portion 13 to lock the grip portion 13 to the shaft A predetermined position in the direction of the axis of the tube 12.

當利用前方具11之突出部111的後端面116將O環14壓入握持部之埋頭孔131的最深部時，在埋頭孔131之底面136與突出部111之後端面116之間，O環14會在軸線方向上被壓縮。在該狀態下，握持部之埋頭孔131之底面136與前方具之突出部111之後端面116之間的間隔會小於O環14剖面之圓形直徑d。故，O環14會朝徑方向外側及內側

彈性變形而更緊密地壓迫握持部之內周面(埋頭孔131之側面)及軸管之握持部插通部121之外周面並接觸。故，當因使用者之書寫而朝與軸線方向正交之方向施加外力時，可防止給予使用者一種握持部13會相對於軸管12朝與軸線方向正交方向移動的感觸。 When the O-ring 14 is pressed into the deepest part of the countersunk hole 131 of the gripping portion by the rear end surface 116 of the protruding portion 111 of the front tool 11, between the bottom surface 136 of the countersink 131 and the rear end surface 116 of the protruding portion 111, the O-ring 14 will be compressed in the axis direction. In this state, the interval between the bottom surface 136 of the countersunk hole 131 of the grip portion and the rear end surface 116 of the protruding portion 111 of the front part will be smaller than the circular diameter d of the cross section of the O-ring 14. Therefore, the O-ring 14 will be radially outward and inward

The inner peripheral surface (side surface of the countersunk hole 131) of the grip portion and the grip portion insertion portion 121 of the shaft tube are elastically deformed to tightly press against the outer peripheral surface of the grip portion. Therefore, when an external force is applied in a direction orthogonal to the axis direction due to the user's writing, the user can be prevented from giving a feeling that the grip 13 moves relative to the shaft tube 12 in the direction orthogonal to the axis direction.

如前所述，本實施形態中，握持部插通部121前方更形成有突起122。故，使用O環1來將握持部13組裝於軸管12後，藉由一在使O環14朝徑方向外側彈性變形之狀態下來使突起122之徑方向外側朝前方通過的步驟，若非刻意要從軸管12拆下O環14，握持部13將不會意外從軸管12朝前方脱落。故，即使在要將前方具11從軸管12拆下之狀態，亦可防止握持部13意外從軸管12朝前方脫落。 As described above, in this embodiment, the protrusion 122 is further formed in front of the grip portion insertion portion 121. Therefore, after the O-ring 1 is used to assemble the grip portion 13 to the shaft tube 12, a step of passing the radially outer side of the protrusion 122 forward in the state of elastically deforming the O-ring 14 radially outward, if not The O-ring 14 is deliberately removed from the shaft tube 12, and the grip 13 will not accidentally fall off from the shaft tube 12 toward the front. Therefore, even in a state where the front tool 11 is to be detached from the shaft tube 12, the grip portion 13 can be prevented from accidentally falling forward from the shaft tube 12.

如以上所述，依據本實施形態之自動鉛筆1，可將握持部13 輕易地組裝於軸管12，且組裝好的握持部1不易自軸管12脱落。 As described above, according to the mechanical pencil 1 of the present embodiment, the grip portion 13 can be easily assembled to the shaft tube 12, and the assembled grip portion 1 is not easily detached from the shaft tube 12.

一般而言，自動鉛筆為了維護或修理，可將前方具自軸管拆下。惟，若如本實施形態之自動鉛筆1般，握持部13是由實質上不會彈性變形之材料形成，且可輕易地將握持部13組裝於軸管12，即使握持部會從軸管脱落也會變得不易脫落，這點絕非亦於思及。故，特別是當使用者為兒童時等，在已將前方具自軸管拆下之狀態下，例如想要修理而大力甩動自動鉛筆時，其握持部也有可能意外順勢飛出。此時，順勢飛出之由實質上不會彈性變形之材料所形成的握持部有可能對周遭人或物造成傷害，因此希望可防止握持部如此從軸管脱落之情況。依據本實施形態之自動鉛筆1之構成，即使在已將前方具11從軸管12拆下之狀態下用力甩動軸管12時，如上所述，亦可達到一良好地防止握持部13從軸管12脱落的優異効果。 Generally speaking, the mechanical pencil can be removed from the front tube for maintenance or repair. However, if like the mechanical pencil 1 of the present embodiment, the grip portion 13 is formed of a material that does not substantially elastically deform, and the grip portion 13 can be easily assembled to the shaft tube 12, even if the grip portion will The fall of the shaft tube will also become difficult to fall off, which is by no means thoughtful. Therefore, especially when the user is a child, etc., in a state where the front tool has been removed from the shaft tube, for example, when the mechanical pencil is shaken vigorously for repair, the grip portion may accidentally fly out. At this time, the grip portion formed of a material that does not substantially elastically deform out of the way may cause damage to people or objects around it, so it is desirable to prevent the grip portion from falling off from the shaft tube in this way. According to the configuration of the mechanical pencil 1 of the present embodiment, even when the front tube 11 is vigorously shaken with the front tool 11 removed from the shaft tube 12, as described above, a good prevention of the grip 13 can be achieved Excellent effect of falling off the shaft tube 12.

而，本實施形態中，文具(筆具)之具體例雖是以自動鉛筆為例來說明，但本發明之態様不限於此，在其他實施形態中，對於例如原子筆等任意文具等、或是具有可於筒狀構件組裝握持部之構成的任意手持道具亦可適用同様構成。舉例言之，化粧料容器可構成如下。 In this embodiment, although a specific example of a stationery (pencil) is described using a mechanical pencil as an example, the state of the invention is not limited to this. In other embodiments, for example, any stationery such as a ballpoint pen, or Any hand-held props with a configuration that can be assembled with a cylindrical member can also be applied to the same configuration. For example, the cosmetics container may be constructed as follows.

上述實施形態中，用於配置O環之“朝前端側開口的環狀凹部”可形成於筒體與握持部之交界處。舉例言之，“朝前端側開口的環狀凹部”亦可由形成於筒體側之凹部來構成，或是由形成於筒體及握持部兩者之凹部來構成。又，為了將軸管與握持部之間形成之空間構造成越往後方越窄，亦可將埋頭孔構造成側面為傾斜形狀，使其相對於軸線具有預定角度之斜面。 In the above-mentioned embodiment, the "ring-shaped recessed portion opening toward the front end side" for arranging the O-ring may be formed at the boundary between the cylindrical body and the grip portion. For example, the "ring-shaped concave portion that opens toward the front end side" may be constituted by a concave portion formed on the side of the cylinder, or a concave portion formed in both the cylinder and the grip portion. In addition, in order to configure the space formed between the shaft tube and the grip portion to become narrower toward the rear, the countersunk hole may be configured to have an inclined side surface with a predetermined angle with respect to the axis.
