Description

本発明は、建物、倉庫、車輌などのドアに適用可能なドアハンドル装置に関し、特に、ハンドルのがたつきを防止することができるドアハンドル装置に関する。 The present invention relates to a door handle device that can be applied to doors of buildings, warehouses, vehicles, and the like, and more particularly to a door handle device that can prevent rattling of the handle.

特許文献１は、ドアハンドル装置のハンドルがたつき防止に関するもので、その明細書本文及び図面には、「ハブ角孔４と角軸５の間、およびハンドル角穴７と角軸５の間のがたつきを確実に防止するために、前記ハブ角孔４内の角軸５の一つの角部にばね片１０を当てて角軸５を対角線方向に押圧し、ハンドル角穴７内の角軸５の一つの角部に止めねじ１１を当てて角軸５を対角線方向に押圧して固定する事項（符号は特許文献１のもの）」が記載されている。 Patent Document 1 relates to prevention of rattling of a handle of a door handle device, and the specification text and drawings include “between the hub square hole 4 and the square shaft 5, and between the handle square hole 7 and the square shaft 5. In order to reliably prevent rattling, the spring piece 10 is applied to one corner of the square shaft 5 in the hub square hole 4 to press the square shaft 5 in the diagonal direction, and the handle square hole 7 "A matter (the reference numeral is that of Patent Document 1)" in which a set screw 11 is applied to one corner of the square shaft 5 and the square shaft 5 is pressed and fixed diagonally.

この特許文献１に記載の発明は、あくまでも、ハンドルのがたつき防止を、角軸（回転角軸）５の一つの角部に組み込んだばね片１０を介して図るものである。 The invention described in Patent Document 1 is intended to prevent the rattling of the handle via a spring piece 10 incorporated in one corner of the angular axis (rotating angular axis) 5.

付言すると、座構成部材とハンドルとの圧接構造を介してハンドルのがたつきを防止するものではない。したがって、ハンドルをその挿入軸の周方向に回転すると、挿入軸の外周面と座本体の中心嵌合部の内周面との間の隙間が原因で「ハンドルのがたつき」が依然として残るという問題点があった。 In addition, rattling of the handle is not prevented via the pressure contact structure between the seat constituent member and the handle. Therefore, when the handle is rotated in the circumferential direction of the insertion shaft, “handle rattling” still remains due to a gap between the outer peripheral surface of the insertion shaft and the inner peripheral surface of the center fitting portion of the seat body. There was a problem.

一方、特許文献２は、ドアハンドル装置の復帰機構に関するもので、その明細書本文の段落００２１、段落００２３等と、図１、図２等には、本願発明に関係のあるドアハンドル装置が記載されている。すなわち、段落００２３には、「上記ドアＡの表側面のエスカッション７は、復帰機構としての環状のねじりバネ１４と、このねじりバネ１４の一端に接続する略リング形状の座金１５とを収容している。上記ねじりバネ１４の他端は上記エスカッション７の内側面に接続している。上記エスカッション７は、上記ねじりバネ１４を保持する押え板１６を上記エスカッション７の他端面側に嵌合して、この他端面から突出する接続棒１７，１７を上記接続穴１３，１３に挿入している」、と記載され、また、図１及び図２には、復帰機構としての環状のねじりバネ１４、エスカッション７及びねじりバネ１４を保持する押え板１６がそれぞれ図示されている（符号は特許文献１のもの）。 On the other hand, Patent Document 2 relates to a return mechanism of a door handle device. Paragraph 0021, paragraph 0023, etc. of the main body of the specification and FIGS. 1, 2 and the like describe a door handle device related to the present invention. Has been. That is, in paragraph 0023, “The escutcheon 7 on the front side of the door A accommodates an annular torsion spring 14 as a return mechanism and a substantially ring-shaped washer 15 connected to one end of the torsion spring 14. The other end of the torsion spring 14 is connected to the inner surface of the escutcheon 7. The escutcheon 7 is formed by fitting a holding plate 16 holding the torsion spring 14 to the other end surface of the escutcheon 7. The connecting rods 17 and 17 projecting from the other end face are inserted into the connecting holes 13 and 13 ”, and FIGS. 1 and 2 show an annular torsion spring 14 as a return mechanism, A presser plate 16 that holds the escutcheon 7 and the torsion spring 14 is shown in the figure (reference numerals are those of Patent Document 1).

この特許文献１のエスカッションに配設されたハンドル用の復帰機構は、典型的な一例であるが、その問題点は、（ａ）復帰機構を構成する部品点数が多いこと、（ｂ）ねじりバネ１４、エスカッション７及びねじりバネ１４等の構成部品がそれぞれ別部品であることから、コスト高となるのみならず、組み合わせに時間がかかることである。 The return mechanism for the handle disposed in the escutcheon of Patent Document 1 is a typical example, but the problems are (a) a large number of parts constituting the return mechanism, and (b) a torsion spring. 14, component parts such as the escutcheon 7 and the torsion spring 14 are separate parts, which not only increases the cost but also requires time for the combination.

なお、ドアハンドル装置は、特許文献１や特許文献２に記載のように、ドアの内壁面に固定的に装着される内側座構成部材と、一方、前記ドアの外壁面に固定的に装着される外側座構成部材と、ドア、外側座構成部材、錠箱及び内側座構成部材をそれぞれ貫通する棒状の回転角軸と、この棒状回転角軸の突出両端部にそれぞれ連結される内側のハンドル並びに外側のハンドルとを備え、前記少なくとも前記内側座構成部材４又は外側座構成部材５のいずれか一方には、ねじりバネを含むハンドル用の復帰機構が設けられている。

Japanese Patent Laid-Open No. 7-293054 JP 2002-235471 A

本発明の所期の目的は、まず、特許文献１の問題点に鑑み、ハンドルの挿入軸の外周面と座本体の中心嵌合部の内周面との間の隙間が原因でハンドルが「がたつく現象」を、座本体の構造に着目して解消することである。次に、ハンドルを復帰用の復帰機構を構成する部品点数を減らして、部品コストの低減化及びハンドルの取付け作業の効率化を図ることである。 The intended purpose of the present invention is, firstly, in view of the problems of Patent Document 1, the handle is formed by the clearance between the outer peripheral surface of the insertion shaft of the handle and the inner peripheral surface of the center fitting portion of the seat body. This is to eliminate the rattling phenomenon by paying attention to the structure of the seat body. Next, the number of parts constituting the return mechanism for returning the handle is reduced, thereby reducing the parts cost and increasing the efficiency of the handle attachment work.

本発明のドアハンドル装置は、ドア１の内壁面１ａに固定的に装着される内側座構成部材４と、一方、前記ドアの外壁面１ｂに固定的に装着される外側座構成部材５と、ドアを含み、外側座構成部材５、錠箱６及び内側座構成部材４をそれぞれ貫通する棒状回転角軸８と、この棒状回転角軸の突出両端部８ａ，８ｂにそれぞれ連結される内側のハンドル２並びに外側のハンドル３とを備えるドアハンドル装置Ｘに於いて、少なくとも前記内側座構成部材４又は外側座構成部材５のいずれか一方には、座本体のドア当接部１３ｂから錠箱の幅広側壁方向へ対向して延びる複数本の弾性変位復帰部２１，２１Ａを設け、これらの弾性変位復帰部は、ハンドルの軸部の座挿入先端部２ａの外周面に圧接する板バネ機能を有する手首部２２、２２と、これらの手首部の各先端部から半径内方向に延びる指状摺接部２３、２３を有し、これらの指状摺接部は、前記棒状回転角軸８の一部をサンドイッチ状に挟むように圧接変位することを特徴とする。 The door handle device of the present invention includes an inner seat constituent member 4 fixedly attached to the inner wall surface 1a of the door 1, and an outer seat constituent member 5 fixedly attached to the outer wall surface 1b of the door, A rod-shaped rotational angle shaft 8 including a door and penetrating the outer seat constituent member 5, the lock box 6 and the inner seat constituent member 4 respectively, and inner handles respectively coupled to the projecting both ends 8a and 8b of the rod-shaped rotational angle shaft 2 and the outer handle 3, at least one of the inner seat constituent member 4 and the outer seat constituent member 5 has a width of the lock box from the door abutting portion 13 b of the seat body. A plurality of elastic displacement return portions 21 and 21A extending opposite to each other in the side wall direction are provided, and these elastic displacement return portions have wrist spring functions that come into pressure contact with the outer peripheral surface of the seat insertion tip portion 2a of the handle shaft portion. and parts 22, 22, Finger-shaped sliding contact portions 23, 23 extending radially inward from respective tip portions of these wrist portions, and these finger-shaped sliding contact portions sandwich a part of the rod-shaped rotation angle shaft 8 in a sandwich shape. It is characterized by being displaced by pressure .

上記構成に於いて、座挿入先端部の外周面に圧接する手首部２２及び回転角軸８の外面に圧接する指状摺接部２３は、座本体の中心嵌合部２０から一連に延在して複数本の弾性変位復帰部を構成していることを特徴とする。 In the above configuration, the wrist portion 22 that is in pressure contact with the outer peripheral surface of the seat insertion tip and the finger-shaped sliding contact portion 23 that is in pressure contact with the outer surface of the rotation angle shaft 8 extend in series from the center fitting portion 20 of the seat body. Thus, a plurality of elastic displacement return portions are configured.

まず、特許文献１の問題点を解消することができる。すなわち、特許文献１のように、必ずしもハンドル角穴内の回転角軸の一つの角部に止めねじを当てて回転角軸を対角線方向に押圧して固定しなくても、座本体に設けた板バネ機能を有する複数本の手首部でもってハンドルの軸部の座挿入先端部の外周面をサンドイッチ状に圧接状態で挟持することができるから、挿入軸の外周面と座本体の中心嵌合部の内周面との間の隙間が原因でハンドルが「がたつく現象」を、簡単な構造により達成することができる。 First, the problem of Patent Document 1 can be solved. That is, as in Patent Document 1, it is not always necessary to apply a set screw to one corner of the rotation angle axis in the handle square hole and press the rotation angle axis in the diagonal direction to fix the plate. Since the outer peripheral surface of the seat insertion tip portion of the shaft portion of the handle can be sandwiched and pressed in a sandwich state with a plurality of wrist portions having a spring function, the outer peripheral surface of the insertion shaft and the center fitting portion of the seat body gap between the inner peripheral surface of the "rattling phenomenon" handle due can be achieved by a simple structure.

次に、特許文献２の問題点を解消することができる。すなわち、復帰機構を構成する部品点数を減らして、部品コストの低減化を図ることができる。また、ハンドルをドアに取付ける前に、従来のように、ハンドル用回転角軸やハンドルそのものと、ハンドル初期位置復帰用バネとの直接的な係わり合い（バネ端の連結工程）がないので、戻しバネとしての弾性変位復帰部を有する座構成部材に対して、ハンドルをそのまま後付けすることができる。付言すると、弾性変位復帰部は、少なくとも内側座構成部材４又は外側座構成部材５のいずれか一方に一体的に設けられているので、組み合わせの作業能率が格段に向上すると共に、座構成部材とバネとしての弾性変位復帰部とは互いに連結されていないことから、ハンドルを簡単に交換することもできる。 Next, the problem of Patent Document 2 can be solved. That is, the number of parts constituting the return mechanism can be reduced to reduce the part cost. In addition, before attaching the handle to the door, there is no direct engagement (spring end coupling process) between the handle rotation angle shaft or the handle itself and the handle initial position return spring. A handle can be retrofitted as it is with respect to a seat constituent member having an elastic displacement return portion as a spring. In addition, since the elastic displacement return portion is integrally provided at least in either the inner seat constituent member 4 or the outer seat constituent member 5, the work efficiency of the combination is greatly improved, and the seat constituent member Since the elastic displacement return portion as a spring is not connected to each other, the handle can be easily replaced.

その他、弾性変位復帰部の指状摺接部２３が、回転角軸８の断面形状に対応して二又状に形成されている実施例の場合には、外拡作用時には、力を分散化させることができる一方、戻り力の作用時には、その力を回転角軸８の各外面に集中化させることができるので、いわゆるソフトなタッチで、かつ確実にハンドル復帰させることができる。 In addition, in the case of the embodiment in which the finger-shaped sliding contact portion 23 of the elastic displacement return portion is formed in a bifurcated shape corresponding to the cross-sectional shape of the rotation angle shaft 8, the force is dispersed during the external expansion action. On the other hand, when a return force is applied, the force can be concentrated on each outer surface of the rotation angle shaft 8, so that the handle can be reliably returned by a so-called soft touch.

そこで、本実施例では、筒状取付け部１６の場合と同様に、弾性変位を有効的にするために、手首部２２の根元部分に相当する部位を含む箇所に適宜形状の凹所２４を形成している。そして、本実施例では、前記手首部２２の内面２２ａは、図３で示すように、内側のハンドル２の軸部の座挿入先端部２ａの角形状外周面に対する摺接面となっている。 Therefore, in the present embodiment, as in the case of the cylindrical mounting portion 16, a suitably shaped recess 24 is formed at a location including a portion corresponding to the root portion of the wrist portion 22 in order to make the elastic displacement effective. is doing. In this embodiment, the inner surface 22a of the wrist portion 22 is a slidable contact surface with respect to the angular outer peripheral surface of the seat insertion tip portion 2a of the shaft portion of the inner handle 2 as shown in FIG.

なお、前記各手首部２２は、その機能を有効的に発揮させるために、先端部に至るにしたがって、若干内側に入り込むようにするのが望ましい。 It is desirable that each wrist portion 22 slightly enters inside as it reaches the tip portion in order to effectively exert its function.

（４）外側座構成部材５
図３を参照にして、外側座構成部材５の構成を説明する。この外側座構成部材５も、内側座構成部材４と同様に、その外周壁が円形、楕円形、正方形等の任意の形状に形成された座本体５ａと、この座本体５ａに外嵌合するキャップ状の化粧カバー５ｂとから成る。
ただ、内側座構成部材４と異なる点は、前記座本体５ａの垂直基板部２６のドア当接面２６ｂに突設された複数個の取付け部２７は、図３で示すように、錠箱６を貫通して内側座構成部材４の筒状取付け部１６に挿入係合する長杆状の接続柱である点、座本体５ａの垂直基板部２６は、直接又は間接的に手首状弾性変位復帰部を有しない点である。 (4) Outer seat constituent member 5
The configuration of the outer seat constituent member 5 will be described with reference to FIG. Similarly to the inner seat constituent member 4, the outer seat constituent member 5 is externally fitted to a seat main body 5 a whose outer peripheral wall is formed in an arbitrary shape such as a circle, an ellipse, or a square. And a cap-shaped decorative cover 5b.
However, the difference from the inner seat constituent member 4 is that a plurality of mounting portions 27 protruding from the door contact surface 26b of the vertical substrate portion 26 of the seat body 5a are provided with a lock box 6 as shown in FIG. The vertical base plate portion 26 of the seat body 5a is directly or indirectly restored to the wrist-like elastic displacement. This is a point that has no part.

本実施例では、極力、固着具を用いないようにするために、内側座構成部材４に対する外側座構成部材５に対する結合方式は、オス・メスのワンタッチ係合方式を採用している。 In this embodiment, a male / female one-touch engagement method is employed as a coupling method for the inner seat constituent member 4 to the outer seat constituent member 5 in order to minimize the use of a fixing tool.

したがって、座本体５の取付け部２７の先端部には、挿入方向に断面波状に整列し、かつ周方向に形成された複数個の周係合部２８が周設され、内側座構成部材４の弾性変位可能な筒状取付け部２６の不番係合突起と係合する。なお、外側座構成部材５も内側座構成部材４と同様に、ドア１の不番貫通孔を基準にしてドア１の外壁面１ｂに固定的に取付けられる。 Therefore, a plurality of circumferential engagement portions 28 that are aligned in a cross-sectional wave shape in the insertion direction and formed in the circumferential direction are provided at the distal end portion of the attachment portion 27 of the seat body 5, It engages with the non-engagement protrusion of the cylindrical mounting portion 26 that can be elastically displaced. The outer seat constituent member 5 is also fixedly attached to the outer wall surface 1 b of the door 1 with reference to the unnumbered through hole of the door 1, similarly to the inner seat constituent member 4.

（５）その他の部材−回転角軸８、内外のハンドル２、３
回転角軸８は、普通一般に「角軸」と称されているものである。したがって、その縦断面は、図５で示すように正方形である。また、内側のハンドル２と外側のハンドル３は、例えば平面視Ｌ形状のレバーハンドルである。内外のレバーハンドル２、３は、周知のように、軸部と、該軸部に連設する把手部とから成り、前記軸部の先端部に固定手段９、１０用の不番の取付け孔が形成されている。 (5) Other members-rotation angle axis 8, inner and outer handles 2, 3
The rotation angle axis 8 is generally called “angular axis”. Therefore, the longitudinal section is a square as shown in FIG. The inner handle 2 and the outer handle 3 are, for example, L-shaped lever handles in plan view. As is well known, the inner and outer lever handles 2 and 3 are each composed of a shaft portion and a grip portion connected to the shaft portion, and an unnumbered mounting hole for the fixing means 9 and 10 at the tip portion of the shaft portion. Is formed.

本実施例では、図３で示すように、内側のレバーハンドル２の軸部の座挿入先端部２ａが、内側座構成部材４のハンドル用貫通孔１１を挿通して、該座挿入先端部２ａの先端面が手首状弾性変位復帰部２１、２１Ａの指状摺接部２３の垂直面に至る。付言すると、前記指状摺接部２３は、仮想線で示した錠箱６の幅広側壁と前記軸部の座挿入先端部２ａとの間に位置する。 In this embodiment, as shown in FIG. 3, the seat insertion tip 2a of the shaft portion of the inner lever handle 2 is inserted through the handle through-hole 11 of the inner seat component 4, and the seat insertion tip 2a. The front end surface of the finger reaches the vertical surface of the finger-like sliding contact portion 23 of the wrist-like elastic displacement return portions 21 and 21A. In addition, the finger-like sliding contact portion 23 is located between the wide side wall of the lock box 6 indicated by the phantom line and the seat insertion tip portion 2a of the shaft portion.

（６）作用
周知のように、ドア１が閉じている場合には、内外のレバーハンドル２、３の把手部は、略水平状態に向いている。一方、操作者が、内外いずれかのレバーハンドル２、３の把手部に手を掛けて操作すると、内外のレバーハンドル２、３は所定位置まで回転して傾く。 (6) Operation As is well known, when the door 1 is closed, the handle portions of the inner and outer lever handles 2 and 3 are in a substantially horizontal state. On the other hand, when the operator puts his / her hand on the handle portion of the inner or outer lever handle 2 or 3 and operates, the inner or outer lever handle 2 or 3 rotates and tilts to a predetermined position.

図７は内外のレバーハンドル２、３が水平状態の場合、図８及び図９は内外のレバーハンドル２、３が所定角度まで回転して傾倒した場合である。内外のレバーハンドル２、３が水平状態の場合は、図１０で示すように、座本体４ａのドア当接部１３ｂから錠箱の幅広側壁方向（手前の方向）へそれぞれ突出する複数本の手首部（断面箇所）２２が、ハンドルの軸部の座挿入先端部２０の外周面に密接状態に対峙し、それらの内面２２ａが前記軸部の座挿入先端部の外周面にサンドイッチ状に圧接或いは当接している。付言すると、ハンドルの軸部の座挿入先端部２ａは、座構成部材の板バネ機能を有する複数本の手首部で線ないし面接触状態に支持されている。 FIG. 7 shows the case where the inner and outer lever handles 2 and 3 are in a horizontal state, and FIGS. 8 and 9 show the case where the inner and outer lever handles 2 and 3 are rotated to a predetermined angle and tilted. When the inner and outer lever handles 2 and 3 are in a horizontal state, as shown in FIG. 10, a plurality of wrists projecting from the door contact portion 13b of the seat body 4a toward the wide side wall (front side) of the lock box. Portion (cross section) 22 is in close contact with the outer peripheral surface of the seat insertion tip 20 of the shaft portion of the handle, and the inner surface 22a thereof is pressed against the outer peripheral surface of the seat insertion tip portion of the shaft portion in a sandwich manner or It is in contact. If it adds, the seat insertion front-end | tip part 2a of the axial part of a handle | steering-wheel is supported in the line | wire or surface contact state by the several wrist part which has the leaf | plate spring function of a seat structural member.

また、回転角軸８の内部（一部）の各外面（４つの面）は、手首状弾性変位復帰部２１、２１Ａの各指状摺接部２３の対向する各内壁面２３ａ、２３ａ（４つの摺接面）に対してそれぞれ面接触状態に当接している。 In addition, the outer surfaces (four surfaces) inside (a part of) the rotation angle shaft 8 are the inner wall surfaces 23a, 23a (4) facing the finger-like sliding contact portions 23 of the wrist elastic displacement return portions 21, 21A. Are in contact with each other).

これに対して、内外のレバーハンドル２、３が所定角度まで回転して傾倒した場合（図８及び図９）には、回転角軸８は内外のレバーハンドル２、３と一体なので、図８の矢印Ａ方向（時計方向）に所定量回転する。回転角軸８が矢印Ａ方向に回転する時、回転角軸８の四つ角（稜線部分）が各指状摺接部２３の各内壁面２３ａ、２３ａに対して摩擦抵抗を与える。 On the other hand, when the inner and outer lever handles 2 and 3 are rotated to a predetermined angle and tilted (FIGS. 8 and 9), the rotation angle shaft 8 is integral with the inner and outer lever handles 2 and 3, so FIG. Rotate a predetermined amount in the direction of arrow A (clockwise). When the rotation angle shaft 8 rotates in the direction of arrow A, the four corners (ridge line portions) of the rotation angle shaft 8 give frictional resistance to the inner wall surfaces 23a and 23a of the finger-like sliding contact portions 23.

しかして、回転角軸８が矢印Ａ方向に回転すると、本実施例では、手首状弾性変位復帰部２１、２１Ａの各手首部２２が弾性力（板バネのバ力）に抗して外側に反る格好となるので、上下の各指状摺接部２３が互いに図８の矢印Ｂ方向（半径外方向）へと離れる。 Thus, when the rotation angle shaft 8 rotates in the direction of the arrow A, in this embodiment, the wrist portions 22 of the wrist-like elastic displacement return portions 21 and 21A are moved outward against the elastic force (the force of the leaf spring). Since it is warped, the upper and lower finger-shaped sliding contact portions 23 are separated from each other in the direction of arrow B (radially outward) in FIG.

付言すると、レバーハンドル２、３の操作時、上下の手首状弾性変位復帰部２１、２１Ａに外拡作用が生じて、図７の状態から図８に示す位置まで外拡変位する。 In other words, when the lever handles 2 and 3 are operated, the upper and lower wrist-like elastic displacement return portions 21 and 21A have an outward expansion action, and the external displacement is performed from the state shown in FIG. 7 to the position shown in FIG.

一方、ドア１を開けたとき、操作者は当該ハンドルから手を放すか或いは力を緩めるが、この時、上下の手首状弾性変位復帰部、２１、２１Ａの弾性変位復帰力（ハンドルを初期位置へと戻す力）が回転角軸８の各外面（４つの面）に集中的にかかる。したがって、内外のレバーハンドル２、３は、内側座構成部材４の手首状弾性変位復帰部、２１、２１Ａの戻り力により水平状態へとスムースに戻る。 On the other hand, when the door 1 is opened, the operator releases his hand from the handle or relaxes the force. At this time, the upper and lower wrist elastic displacement return portions 21 and 21A elastic displacement return force (the handle is moved to the initial position). Force) is concentrated on each outer surface (four surfaces) of the rotation angle axis 8. Therefore, the inner and outer lever handles 2 and 3 return smoothly to the horizontal state by the return force of the wrist-like elastic displacement return portions 21 and 21A of the inner seat constituent member 4.

発明の実施の形態で示した実施例に於いて、２本の手首状弾性変位復帰部２１、２１Ａは、斜め左上に位置する上側の手首状弾性変位復帰部２１と、一方、斜め右下に位置する下側の手首状弾性変位復帰部２１Ａに区分けすることができるが、もちろん、これらの位置は限定されるものではなく、回転角軸８の外周面に対応して適宜に位置付けられる。 In the example shown in the embodiment of the invention, the two wrist-like elastic displacement return portions 21 and 21A are arranged on the upper wrist-like elastic displacement return portion 21 located diagonally in the upper left, while on the diagonally lower right. Although it can be divided into the lower wrist-like elastic displacement return portion 21A located, of course, these positions are not limited, and are appropriately positioned corresponding to the outer peripheral surface of the rotation angle shaft 8.

したがって、斜め左下と斜め右上に配設する場合もある。また、二股状の指状摺接部２３の股部分（中心部分）には、軸方向に半円弧状の小溝２９を形成している（他の新規事項）が、これは、二股状の指状摺接部２３が裂けないことを目的としたものであり、本発明の所期の目的との関係では、発明の特定要件ではない。 Therefore, it may be disposed at the diagonally lower left and diagonally upper right. In addition, a semicircular arc-shaped small groove 29 is formed in the crotch portion (center portion) of the bifurcated finger-shaped sliding contact portion 23 (another new matter). This is intended to prevent the slidable contact portion 23 from tearing, and is not a specific requirement of the invention in relation to the intended purpose of the present invention.

なお、本実施例では、「手首部」は複数本であり、これらの手首部は、ハンドルの軸部の座挿入先端部の外周面にサンドイッチ状に圧接変位する板バネであるが、該手首部を単数にしても良い。手首部が単数の場合は、例えば先端面Ｃ型形状に形成する。 In this embodiment, there are a plurality of “wrist parts”, and these wrist parts are leaf springs that are pressed and displaced in a sandwich manner on the outer peripheral surface of the seat insertion tip of the handle shaft part. The number of parts may be singular. When the wrist part is single, it is formed in a C-shaped tip surface, for example.
