Description

本発明はシリンダー錠の鍵に関し、特に板状或いは環状可動障害子が外筒体の半径方向にスライドする方式のシリンダー錠の鍵及びその鍵材に関する。 The present invention relates to a key for a cylinder lock, and more particularly to a key for a cylinder lock in which a plate-like or annular movable obstruction slides in a radial direction of an outer cylinder and a key material thereof.

特許文献１には、「内筒（２）の径方向に断面大略矩形状である鍵挿入孔（３）の短尺巾側面（３ａ）と長尺巾側面（３ｂ）からガイド孔（４、５）を夫々径方向に外筒まで穿設して、両ガイド孔内に一群のピンタンブラ（６、７）を納めてなるシリンダー錠用の鍵であって、鍵本体（Ａ）を上記鍵挿入孔（３）と適合する断面矩形状に成形すると共にその側面（Ａ１）と板面（Ａ２）とに上記ピンタンブラ（６、７）をレベル合致状態に作動せしめる鍵部（１０、１１）を大略倒円錐台形状に凹設形成してなる鍵」が記載されている。なお、前記鍵部とは、断面すり鉢形状の窪みを意味する。 Patent Document 1 states that “the guide hole (4, 5) extends from the short side surface (3a) and the long side surface (3b) of the key insertion hole (3) having a substantially rectangular cross section in the radial direction of the inner cylinder (2). ) In the radial direction to the outer cylinder, and a cylinder lock key in which a group of pin tumblers (6, 7) are accommodated in both guide holes, and the key body (A) is inserted into the key insertion hole. Key sections (10, 11) that are molded into a rectangular cross-section that conforms to (3) and that operate the pin tumblers (6, 7) on the side surface (A1) and the plate surface (A2) in a level-matching state are generally tilted. "Keys that are formed in a truncated cone shape" are described. In addition, the said key part means the hollow of cross-sectional mortar shape.

この特許文献１に記載の鍵について検討して見るに、実用新案登録請求の範囲に於いて、例えば鍵挿入孔（３）、一群のピンタンブラ（６、７）を納めてなるシリンダー錠用の鍵、鍵本体（Ａ）を上記鍵挿入孔（３）と適合する断面矩形状に成形する、その側面（Ａ１）と板面（Ａ２）とに上記ピンタンブラ（６、７）をレベル合致状態に作動せしめる鍵部（１０、１１）を大略倒円錐台形状に凹設形成してなる等の文言は、該特許文献１の鍵の形状、構造等を特定しているものと理解することができ、また該特許文献１の鍵は、ピンタンブラー方式の錠前に適用されるものであることは、文言上明らかである。 Examining and examining the key described in Patent Document 1, in the scope of the utility model registration request, for example, a key for a cylinder lock containing a key insertion hole (3) and a group of pin tumblers (6, 7). The key body (A) is molded into a rectangular cross section suitable for the key insertion hole (3), and the pin tumblers (6, 7) are operated to match the level on the side surface (A1) and the plate surface (A2). It can be understood that the words such as the key portions (10, 11) to be sunk are formed in a substantially inverted truncated cone shape to specify the shape, structure, etc. of the key in Patent Document 1, Further, it is clear from the wording that the key of Patent Document 1 is applied to a pin tumbler lock.

ところで、ピンタンブラー方式の錠前に於いて、その鍵違いを大きくするには、例えば錠前を長くするか、或いはピンタンブラーの形状を細目のものにしなければならないという問題点がある。そもそも、鍵違いを生み出す要素は、基本的にタンブラーの形状の差（半径）の種類と、シリンダーに組み込まれるタンブラーの本数の二つである。 However, in the pin tumbler type lock, in order to increase the key difference, there is a problem that, for example, the lock must be lengthened or the pin tumbler must have a fine shape. In the first place, there are basically two factors that generate the key difference: the type of tumbler shape (radius) and the number of tumblers built into the cylinder.

しかして、鍵違いの数をより多くするには、タンブラーの差をより細かい段階に設定するか、タンブラーの数を増やすか、あるいはその両方を行えばよい。ところが、タンブラーの段階と本数（列数）を増やせば鍵違いの数は急激に増すとはいえ、現実にはこれらを無暗に増やすことは難しい。分断部（シアライン）の段階（ピンの移動方向の深さ）を極端に細かく設定すると、タンブラーの先端部や鍵の刻みが摩耗して段差が不明確になった場合、別の鍵でも合いかねない危険性が生じやすい。 Therefore, in order to increase the number of key differences, the tumbler difference may be set at a finer level, the number of tumblers may be increased, or both. However, if the number of tumblers and the number of rows (columns) increase, the number of key differences increases rapidly, but in reality it is difficult to increase them silently. If the dividing part (shear line) stage (the depth of the pin movement direction) is set extremely finely, if the tip of the tumbler or the key notch wears out and the step becomes unclear, another key may fit. There is no risk to occur.

一方、ピンの本数を直列方向に増やすと、シリンダーは長くなってしまう。戸の表面からシリンダーが突き出しすぎては、暴力破壊に対して破壊工具の手掛かりになりやすい。したがって、一般には、５段階か６段階に変化するピンをせいぜい７本使用したものが、鍵違い数と耐久性の両立をはかる高品位のシリンダーとして使用されている
以上のように、ピンタンブラー方式の錠前の鍵に於いては、鍵違いを大きくすると言っても、それなりに限界があり、鍵の製造を困難にすることができない。 On the other hand, if the number of pins is increased in the series direction, the cylinder becomes longer. If the cylinder protrudes too far from the door surface, it can easily become a clue to the destruction tool against violent destruction. Therefore, in general, 7 pins that change in 5 or 6 steps are used as high-grade cylinders that achieve both the number of key differences and durability. As described above, the pin tumbler method In the key of the lock, even if the key difference is increased, there is a limit to it, and it is difficult to manufacture the key.

(See FIG. 2).

しかして、図４で示すように、トラック形状の仕切板１６によって区画された一つのタンブラー収容部２７（手前に見える非ハッチングの部分）は、上下のタンブラーバネ用収容部２８と連通すると共に、その上下・左右の幅は、後述する板状或いは環状可動障害子（３種類のタンブラー）Ｚの外周形状に対応して適宜に設定される。実施形態では、一つのタンブラー収容部２７の間口に相当する一端開口２７ａは幅広く、上下の段差状ストッパー面１５ｂ、１５ｂ側の奥口に相当する他端開口２７ｂは幅狭である。このタンブラー収容部２７は、実施形態では合鍵Ｙの挿入方向Ａに仕切板１６を介して列状に合計１１個設けられている。 As shown in FIG. 4, one tumbler accommodating portion 27 (a non-hatched portion visible in the foreground) partitioned by the track-shaped partition plate 16 communicates with the upper and lower tumbler spring accommodating portions 28. The vertical and horizontal widths are appropriately set corresponding to the outer peripheral shape of a plate-like or annular movable obstacle (three types of tumblers) Z described later. In the embodiment, the one end opening 27a corresponding to the opening of one tumbler accommodating portion 27 is wide, and the other end opening 27b corresponding to the upper and lower stepped stopper surfaces 15b and 15b is narrow. In the embodiment, a total of 11 tumbler accommodating portions 27 are provided in a row in the insertion direction A of the key Y through the partition plate 16.

しかして、１３は内筒本体１５の上部と下部に対称的に形成された解錠切欠で、この解錠切欠１３は前述した上下の実体部分１５ａ、１５ａの中央部に半径内方向に向かって段差状に形成され、その外側幅広切欠１３ａはロッキングバー１２の尖端部１２ａを嵌合案内し、一方、タンブラー収容部２７と連通する内側幅狭切欠１３ｂは前記ロッキングバー１２の係合板部分１２ｂを嵌合案内する。２８はタンブラー収容部２７内の適宜箇所に形成されたバネ端支持面を有するタンブラーバネ収容部で、実施形態では、上下の段差状実体部分１５ａ、１５ａの内側に対向して水平方向に一対設けられている。 Therefore, 13 is an unlocking notch formed symmetrically at the upper and lower parts of the inner cylinder main body 15, and this unlocking notch 13 is directed radially inward at the center of the upper and lower body parts 15a, 15a. The outer wide notch 13a is formed to be stepped, and guides and guides the pointed end 12a of the locking bar 12. On the other hand, the inner narrow notch 13b communicating with the tumbler accommodating portion 27 connects the engaging plate portion 12b of the locking bar 12. Guidance guide. Reference numeral 28 denotes a tumbler spring accommodating portion having a spring end support surface formed at an appropriate location in the tumbler accommodating portion 27. In the embodiment, a pair of tumbler spring accommodating portions 15a and 15a are provided in the horizontal direction so as to face the inner sides of the upper and lower stepped entity portions 15a It has been.

次に同様に図４を参照にして仕切板１６を説明する。なお、設計如何によっては仕切板１６を円形や楕円形に形成し、内筒本体１５の解錠切欠１３と一致する仕切板解錠切欠を形成しても良いが、実施形態では、外観上トラック形状に形成している。また設計如何によっては、複数の仕切板１６を内筒本体１５自体に一体形成しても良い。本実施形態では、出願人が提案した特許第４００８３０２号の特許発明（図３、図４）と同様に、内筒本体１５と仕切板１６は別個の部材であり、二つの弧状分割片を一体的に組み合わせて内筒本体１５を形成した後に、該内筒本体１５に多数の仕切板１６を一体的に組み込み、タンブラー収容部２７を区画形成している。 Next, the partition plate 16 will be described with reference to FIG. Depending on the design, the partition plate 16 may be formed in a circular shape or an oval shape, and a partition plate unlocking notch that coincides with the unlocking notch 13 of the inner cylinder main body 15 may be formed. It is formed into a shape. Further, depending on the design, a plurality of partition plates 16 may be integrally formed with the inner cylinder main body 15 itself. In this embodiment, like the patent invention of the patent No. 4008302 proposed by the applicant (FIGS. 3 and 4), the inner cylinder body 15 and the partition plate 16 are separate members, and the two arc-shaped divided pieces are integrated. After the inner cylinder main body 15 is formed in combination, a large number of partition plates 16 are integrated into the inner cylinder main body 15 so that the tumbler accommodating portions 27 are partitioned.

ところで、両端部又は挿入部端（図面上、左端部）が弧状の嵌合突片を有するトラック形状の仕切板１６は、矩形状の連結孔１８、小円形状の貫通小孔２１及び中央部に形成された横長矩形状の案内開口２９を有する。 Incidentally, the track-shaped partition plate 16 having arc-shaped fitting protrusions at both ends or the insertion portion end (left end portion in the drawing) has a rectangular connecting hole 18, a small circular through hole 21 and a central portion. A horizontally-long rectangular guide opening 29 is formed.

次に図２と図４を参照にして錠後端部７側の構成を説明する。前述したように、錠後端部７はテールピース８を有するが、該テールピース８は、外筒体２の後端部に設けられたワッシヤーリング３１ａ、ストッパーリング３１ｂ等の止め具３１を介して外筒体２の後端部内に回動自在に嵌合するテールプラグ３２の中心部に取付けられている。 Next, the structure of the lock rear end 7 side will be described with reference to FIGS. As described above, the lock rear end portion 7 has the tail piece 8, and the tail piece 8 has a stopper 31 such as a washer ring 31 a and a stopper ring 31 b provided at the rear end portion of the outer cylindrical body 2. And is attached to the center portion of the tail plug 32 that fits in the rear end portion of the outer cylindrical body 2 in a freely rotatable manner.

錠後端部７を構成するテールプラグ３２は、錠先端部４と同様に連結棒１９の後端部を支持する後支持孔３３を一対有している。連結棒１９は、内筒本体１５に組み込まれた後述の板状或いは環状可動障害子Ｚ及び仕切板１６を貫通した状態で、その先端部は前支持孔２５に、一方、後端部は後支持孔３３に支持され、実施形態では、前記前支持孔２５に組み込まれた連結棒付勢バネ３４によって錠後端部７の方向に付勢されている。またガイド兼連結棒２２も連結棒１９と同様に板状或いは環状可動障害子Ｚ及び仕切板１６を貫通した状態で、図示しない前後の支持孔にそれぞれ支持されている。 The tail plug 32 constituting the lock rear end portion 7 has a pair of rear support holes 33 for supporting the rear end portion of the connecting rod 19 like the lock front end portion 4. The connecting rod 19 penetrates a later-described plate-like or annular movable obstruction Z and the partition plate 16 incorporated in the inner cylinder main body 15, and its front end portion is a front support hole 25, while its rear end portion is a rear end. It is supported by the support hole 33, and in the embodiment, is biased in the direction of the lock rear end portion 7 by a connecting rod biasing spring 34 incorporated in the front support hole 25. Similarly to the connecting rod 19, the guide / connecting rod 22 is also supported by front and rear support holes (not shown) while penetrating the plate-like or annular movable obstruction Z and the partition plate 16.

さらに錠本体の構成について説明する。まず図３及び図４を参照にして環状に形成された板状或いは環状可動障害子Ｚを説明する。図３及び図４には板状或いは環状可動障害子Ｚを構成する３種類のタンブラーの内の第１タンブラー４１が見える。例えば図４に記載の第１タンブラー４１を基準にすると、右側の大きな弧状に形成された右端部（ここでは「一端部４１ａ」とする）は、外筒体２の内周面２ａの曲率に対応して形成されているので、ダンブラーバネ４２に付勢されている状態（施錠状態）では、外筒体２の内周面２ａに圧接する。左側の小さな弧状端面を有する突起状の左端部（ここでは「突起状他端部４１ｂ」とする）は、解錠時、タンブラー収容部２７を構成する左側の他端開口２７ｂに係入可能であると共に、その小さな弧状端面は外筒体２の内周面２ａにも当接可能である。水平面を有する上側の端部（ここでは「上端部４１ｃ」とする）は、ロッキングバー１２の係合板部分１２用の受け入れ凹所４８を有し、水平面を有する下側の端部（ここでは「下端部４１ｄ」とする）も、同様に前記係合板部分１２用の受け入れ凹所４８を有する。なお、後述するように板状或いは環状可動障害子Ｚは、非真円形状の環状板体に形成している。 Further, the configuration of the lock body will be described. First, a plate-like or annular movable obstruction Z formed in an annular shape will be described with reference to FIGS. 3 and 4, the first tumbler 41 of the three types of tumblers constituting the plate-like or annular movable obstacle Z can be seen. For example, when the first tumbler 41 shown in FIG. 4 is used as a reference, the right end portion (hereinafter referred to as “one end portion 41a”) formed in a large arc shape on the right side has a curvature of the inner peripheral surface 2a of the outer cylindrical body 2. Since they are formed correspondingly, they are pressed against the inner peripheral surface 2 a of the outer cylindrical body 2 in a state where the damper springs 42 are biased (locked state). The left end of the protrusion having a small arc-shaped end surface on the left side (here, “projection-like other end portion 41b”) can be engaged with the other end opening 27b on the left side constituting the tumbler housing portion 27 when unlocked. At the same time, the small arcuate end surface can also contact the inner peripheral surface 2 a of the outer cylinder 2. The upper end portion (herein referred to as “upper end portion 41 c”) having a horizontal surface has a receiving recess 48 for the engaging plate portion 12 of the locking bar 12, and the lower end portion (here “ Similarly, the lower end 41d "has a receiving recess 48 for the engagement plate portion 12. As will be described later, the plate-like or annular movable obstruction Z is formed as a non-circular annular plate.

しかして、４３は中心部に形成されたブレード用貫通孔で、このブレード用貫通孔４３は、実施形態では内周縁としての左右の垂直端４３ａと上下の水平端４３ｂを有する横方向の矩形状に形成されている。そして、ブレード用貫通孔４３を形成する左右の垂直端４３ａ、４３ａの略中央部分には、ブレード用貫通孔４３と連通する半径外方向の小さな切欠溝４４、４４が対向状態に形成され、これにより、小さな切欠溝４４の水平端とブレード用貫通孔４３の前記垂直端４３ａが略直交状態に交わる角部分（実施形態では４個）が、例えば合鍵ＹのブレードＢの平坦部７１の縁部分７１ａに形成された水平切欠溝ａと係合する第１係合部分４５に相当する。実施形態では、前記第１係合部分４５は合鍵Ｙの平坦部７１の一側上面と一側下面に形成された上下一対の水平切欠溝ａに係合するように上下に一対形成されている。それ故に、前記水平切欠溝ａと前記第１係合部分４５の係合位置如何によって、第１タンブラー４１のスライト位置が決定付けられる。 Thus, reference numeral 43 denotes a blade through hole formed in the center. In the embodiment, the blade through hole 43 has a lateral rectangular shape having left and right vertical ends 43a and upper and lower horizontal ends 43b as inner peripheral edges. Is formed. In the substantially central part of the left and right vertical ends 43a, 43a forming the blade through-hole 43, small radially outward cutout grooves 44, 44 communicating with the blade through-hole 43 are formed in an opposing state. Accordingly, the corner portion (four in the embodiment) where the horizontal end of the small notch groove 44 and the vertical end 43a of the blade through-hole 43 intersect in a substantially orthogonal state is, for example, the edge portion of the flat portion 71 of the blade B of the key Y It corresponds to the first engagement portion 45 that engages with the horizontal cutout groove a formed in 71a. In the embodiment, a pair of the first engaging portions 45 are formed vertically so as to engage with a pair of upper and lower horizontal cutout grooves a formed on one upper surface and one lower surface of the flat portion 71 of the key Y. . Therefore, the slite position of the first tumbler 41 is determined by the engagement position of the horizontal cutout groove a and the first engagement portion 45.

４６はブレード用貫通孔４３を挟むように上下に形成された連結棒１９用貫通孔で、この連結棒１９用貫通孔４６は、第１タンブラー４１がダンブラーバネ４２のバネ力に抗して図面上左側にスライドすることから、長孔矩形状に形成されている。したがって、連結棒１９用貫通孔４６は第１タンブラー４１を案内する案内長孔としての機能を果たす。さらに、４７は一端部４１ａと突起状他端部４１ｂに一対形成された案内長孔で、これらの案内長孔４７にはガイド兼連結棒２２がそれぞれ挿通する。 Reference numeral 46 denotes a through hole for the connecting rod 19 formed vertically so as to sandwich the through hole 43 for the blade. The through hole 46 for the connecting rod 19 is formed by the first tumbler 41 resisting the spring force of the dumble spring 42. Since it slides to the upper left side, it is formed in a long hole rectangular shape. Therefore, the through hole 46 for the connecting rod 19 functions as a guide long hole for guiding the first tumbler 41. Further, 47 is a pair of guide long holes formed in the one end portion 41a and the projecting other end portion 41b, and the guide and connecting rods 22 are inserted through these guide long holes 47, respectively.

次に、図５及び図６を参照にして環状に形成された第２の板状或いは環状可動障害子Ｚを説明する。図５は図３と同様の縦断面図で、内筒本体１５の各タンブラー収容部２７内にそれぞれダンブラーバネ４２に付勢された状態で外筒体２の内周面２ａに大きな弧状面の一端部が圧接した状態で見えるのが第２タンブラー５１である。 Next, the second plate-shaped or annular movable obstruction Z formed in an annular shape will be described with reference to FIGS. FIG. 5 is a longitudinal sectional view similar to FIG. 3, and a large arcuate surface is formed on the inner peripheral surface 2 a of the outer cylindrical body 2 in a state where each tumbler accommodating portion 27 of the inner cylindrical main body 15 is urged by the damper spring 42. The second tumbler 51 can be seen in a state where the one end is in pressure contact.

したがって、図６は板状或いは環状可動障害子Ｚを構成する３種類のタンブラーの内の第２タンブラー５１の正面図である。この第２タンブラー５１は、ブレード用貫通孔５３及び該ブレード用貫通孔５３を形成する上下の水平端５３ｂの中央部に半径内方向に突設形成された第２係合部分５５を除き、その余の構成は前述した第１タンブラー４１と同様なので、説明の便宜上、同一の符号を付して重複する説明を割愛する。 Accordingly, FIG. 6 is a front view of the second tumbler 51 among the three types of tumblers constituting the plate-like or annular movable obstacle Z. The second tumbler 51 has a blade through-hole 53 and a second engaging portion 55 that is formed projecting radially inwardly at the center of the upper and lower horizontal ends 53b that form the blade through-hole 53. Since the remaining configuration is the same as that of the first tumbler 41 described above, the same reference numerals are assigned for the sake of convenience of description, and redundant descriptions are omitted.

なお、図６で示すように、第１タンブラー４１の場合と同様に上下左右の各端部は、ここでも「一端部５１ａ」、「突起状他端部５１ｂ」、「上端部５１ｃ」、「下端部５１ｄ」とする。この第２タンブラー５１も第１タンブラー４１と同様に非真円形状の環状形態であるが、鍵違いの増大化を図るためにその中心部を水平方向に切断して「ニ分割」にしても良い。 As shown in FIG. 6, as in the case of the first tumbler 41, the upper, lower, left and right end portions are again “one end portion 51 a”, “projection-like other end portion 51 b”, “upper end portion 51 c”, “ The lower end 51d ”. Similarly to the first tumbler 41, the second tumbler 51 has a non-circular annular shape. However, in order to increase the key difference, the center portion thereof is cut in the horizontal direction to be “divided into two”. good.

しかして、第１タンブラー４１の第１係合部分４５と異なる第２タンブラー５１の前記第２係合部分５５は、ブレードＢの平坦部７１の中央部部分にブレードＢの挿入方向に沿って波状に形成された長溝ｂと係合する。付言すると、前記長溝ｂと前記第２係合部分５５の係合位置如何によって、第２タンブラー５１のスライト位置が決定付けられる。 Thus, the second engagement portion 55 of the second tumbler 51, which is different from the first engagement portion 45 of the first tumbler 41, is wavy along the insertion direction of the blade B in the central portion of the flat portion 71 of the blade B. It engages with the long groove b formed in the. In addition, the slite position of the second tumbler 51 is determined by the engagement position of the long groove b and the second engagement portion 55.

図７及び至図８を参照にして環状に形成された第３の板状或いは環状可動障害子Ｚを説明する。図７は図３（図５）と同様の縦断面図で、内筒本体１５の各タンブラー収容部２７内にそれぞれダンブラーバネ４２に付勢された状態で外筒体２の内周面２ａに大きな弧状面の一端部が圧接した状態で見えるのが第３タンブラー６１である。 A third plate-shaped or annular movable obstruction Z formed in an annular shape will be described with reference to FIGS. 7 and 8. FIG. 7 is a longitudinal sectional view similar to FIG. 3 (FIG. 5), and is applied to the inner peripheral surface 2 a of the outer cylindrical body 2 while being urged by the damper spring 42 in each tumbler accommodating portion 27 of the inner cylindrical main body 15. The third tumbler 61 can be seen in a state where one end portion of the large arcuate surface is in pressure contact.

したがって、図８は板状或いは環状可動障害子Ｚを構成する３種類のタンブラーの内の第３タンブラー５１の正面図である。この第３タンブラー６１は、ブレード用貫通孔６３及び該ブレード用貫通孔６３を形成する左右の垂直端６３ａのいずれか一方（実施形態）又は両方の中央部に半径内方向に突設形成された第３係合部分６５を除き、その余の構成は前述した第１タンブラー４１や第２タンブラー５１と同様なので、説明の便宜上、第１タンブラー４１と同一の符号を付して重複する説明を割愛する。 Therefore, FIG. 8 is a front view of the third tumbler 51 among the three types of tumblers constituting the plate-like or annular movable obstacle Z. The third tumbler 61 is formed so as to project radially inward at either one (embodiment) of the blade through-hole 63 and the left and right vertical ends 63a forming the blade through-hole 63 or in the center of both. Except for the third engaging portion 65, the rest of the configuration is the same as that of the first tumbler 41 and the second tumbler 51 described above, and therefore, for convenience of explanation, the same reference numerals as those of the first tumbler 41 are used and redundant explanation is omitted.

次に、図２７は合鍵の第２実施形態を示す斜視図である。実施形態の合鍵ＹのブレードＢは、普通一般に使用されている長板のものであるが、例えば合鍵Ｙ１のブレードＢ１は、長板のものではなく、図２７及び半径方向の断面図である図２８に示すように外周面の一部又は全部が曲線状に形成された棒状のものであっても良い。この場合には、ブレードＢ１に「明確な縁部」が存在しないものもあり得るので、図２８の概略断面説明図を参照にして、第１乃至第３タンブラー４１Ａ、５１Ａ、６１の３種類の各係合部分（第１係合部分４５、第２係合部分５５、第３係合部分６５）に対応するブレードＢ１の３種類の各被係合部分（水平切欠溝ａ、波状長溝ｂ、窪みｃ）の形成位置を説明すると次の通りである。 Next, FIG. 27 is a perspective view showing a second embodiment of the key combination. The blade B of the key Y in the embodiment is of a generally used long plate. For example, the blade B1 of the key Y1 is not of a long plate, but is a cross-sectional view in FIG. 27 and a radial direction. As shown in 28, a part or all of the outer peripheral surface may be a rod-like shape formed in a curved shape. In this case, the blade B1 may not have a “clear edge”, and therefore, referring to the schematic cross-sectional explanatory view of FIG. 28, the three types of first to third tumblers 41A, 51A, 61 are provided. Three types of engaged portions (horizontal notch groove a, wavy long groove b, b) corresponding to each engaging portion (first engaging portion 45, second engaging portion 55, third engaging portion 65) The formation position of the depression c) will be described as follows.

すなわち、図２８に於いて、ＨはブレードＢ１の断面の中心部（軸線）Ｏと直交する水平線とし、一方、Ｖを前記中心部（軸線）Ｏと直交する垂直線とした場合に於いて、前記垂直線Ｖが通るブレードＢ１の外周面の一部に前記波状長溝ｂが形成され、この波状長溝ｂの形成位置に対して略９０度と成る前記水平線Ｈが通るブレードＢ１の外周面の一部に前記窪みｃが形成され、さらに、前記波状長溝ｂと前記窪みｃの間で、これらの被係合部分と連通しないようにブレードＢ１の外周面の一部に前記水平切欠溝ａがブレードＢ１の中心部寄りの部位に向かって形成されている。実施形態では、前記窪みｃはすり鉢形状であり、また前記水平切欠溝ａは端面Ｌ字形状である。 That is, in FIG. 28, H is a horizontal line orthogonal to the center (axis) O of the cross section of the blade B1, while V is a vertical line orthogonal to the center (axis) O. The wavy long groove b is formed in a part of the outer peripheral surface of the blade B1 through which the vertical line V passes, and the one of the outer peripheral surface of the blade B1 through which the horizontal line H is about 90 degrees with respect to the formation position of the wavy long groove b. The recess c is formed in the portion, and the horizontal notch groove a is formed in a part of the outer peripheral surface of the blade B1 so as not to communicate with the engaged portions between the waved long groove b and the recess c. It is formed toward a portion closer to the center of B1. In the embodiment, the recess c has a mortar shape, and the horizontal notch groove a has an end face L shape.

しかして、図２９の（ａ）は上下に二分割した第１タンブラー４１Ａの第１係合部分４５と合鍵ＹＩのブレードＢ１の水平切欠溝ａとの係合を示す概略説明図、図２９の（ｂ）は上下に二分割した第２タンブラー５１Ａの第２係合部分５５と前記ブレードＢ１の長溝ｂとの係合を示す概略説明図、図２９の（ｃ）は第３タンブラー６１の第３係合部分６５とブレードＢ１の窪みｃとの係合を示す概略説明図である。 29 (a) is a schematic explanatory view showing the engagement between the first engagement portion 45 of the first tumbler 41A divided into two vertically and the horizontal notch groove a of the blade B1 of the key YI.
