しかし、上記公報に記載の従来のシフトノブ構造では組み付けに手間を要するとともに、シフトノブ本体の材料として陶磁器や硬質発泡ウレタン等を使用することができないという問題があった。 However, the conventional shift knob structure described in the above publication has a problem in that it takes time to assemble, and ceramics, rigid foamed urethane, or the like cannot be used as the material of the shift knob body.

そこで、本発明はこのような課題を解決するもので、簡易な組み付けが可能で、かつシフトノブ本体の材料を、陶磁器や硬質発泡ウレタンを含む広い範囲から選択することができる車両用シフトノブを提供することを目的とする。 Therefore, the present invention solves such a problem, and provides a vehicle shift knob that can be easily assembled and can select a material of the shift knob body from a wide range including ceramics and rigid foamed urethane. For the purpose.

上記目的を達成するために、本第１発明では、一端（１２）へ開放する取付孔（１３）を形成したシフトノブ本体（１）と、取付孔（１３）内に挿入されて孔内周面に接着剤によって接合されるとともに、内周にネジ部（２２１）が形成された筒状の鞘部材（２）と、取付孔（１３）から突出する鞘部材（２）の端部（２３）外周面に一端（３１）開口縁が係合させられてシフトノブ本体（１）の一端（１２）に位置決めされ、取付孔（１３）に連通させられる筒状のロアカバー（３）とを備え、レバーシャフト（４）の先端ネジ部（４１１）を、ロアカバー（３）内を通して鞘部材（２）内に挿入してその内周ネジ部（２２１）に結合する。 In order to achieve the above object, according to the first aspect of the present invention, a shift knob body (1) having a mounting hole (13) opened to one end (12), and an inner peripheral surface of the hole inserted into the mounting hole (13). And a cylindrical sheath member (2) having a screw portion (221) formed on the inner periphery thereof, and an end portion (23) of the sheath member (2) protruding from the mounting hole (13). A cylindrical lower cover (3) that is positioned at one end (12) of the shift knob main body (1) with one end (31) opening edge engaged with the outer peripheral surface and communicated with the mounting hole (13); The tip screw portion (411) of the shaft (4) is inserted into the sheath member (2) through the lower cover (3) and coupled to the inner peripheral screw portion (221).

本第１発明においては、シフトノブ本体の取付孔内に鞘部材を挿入してこれを接着剤で接合した後、鞘部材に係合させてロアカバーをシフトノブ本体と一体化し、ロアカバーを通して鞘部材内にレバーシャフトを通して両者をネジ部で結合することによって、簡易な組み付けが可能である。このような構造によれば、シフトノブ本体の材料として、陶磁器や硬質発泡ウレタンを含む広い範囲のものを使用することができる。 In this 1st invention, after inserting a sheath member in the attachment hole of a shift knob main body, joining this with an adhesive agent, engaging with a sheath member, a lower cover is integrated with a shift knob main body, and it passes in a sheath member through a lower cover. A simple assembly is possible by connecting the two through the lever shaft with a screw portion. According to such a structure, a wide range of materials including ceramics and rigid foamed urethane can be used as the material of the shift knob body.

本第２発明では、上記接着剤を弾性接着剤とし、レバーシャフト（４）の先端ネジ部（４１１）を鞘部材（２）の内周ネジ部（２２１）に結合した際に当該鞘部材（２）が拡大変形させられて食い込みトルクを生じるようにする。本第２発明においては、食い込みトルクによってレバーシャフトに対するシフトノブ本体の相対回転が防止される。 In this 2nd invention, when the said adhesive agent is made into an elastic adhesive and the front-end | tip thread part (411) of a lever shaft (4) is couple | bonded with the internal peripheral thread part (221) of a sheath member (2), the said sheath member ( 2) is expanded and deformed to generate biting torque. In the second invention, the relative rotation of the shift knob body with respect to the lever shaft is prevented by the biting torque.

なお、上記カッコ内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。 In addition, the code | symbol in the said parenthesis shows the correspondence with the specific means as described in embodiment mentioned later.

以上のように、本発明の車両用シフトノブによれば、簡易な組み付けが可能で、かつシフトノブ本体の材料を、陶磁器や硬質発泡ウレタンを含む広い範囲から選択することができる。 As described above, according to the vehicle shift knob of the present invention, simple assembly is possible, and the material of the shift knob body can be selected from a wide range including ceramics and rigid foamed urethane.

図１には車両用シフトノブ（以下、単にシフトノブという）の分解斜視図を示す。シフトノブは本体１と鞘部材２、ロアカバー３によって構成されて、レバーシャフト４の先端に取り付けられる。シフトノブ本体１は本実施形態では陶磁器の焼成品で、先端１１が曲面、基端１２が平面となった軸対象の回転体形状をしている（図２、図３）。なお、シフトノブ本体１を硬質発泡ウレタンや木材で形成しても良い。シフトノブ本体１には軸中心に、基端１２へ開放する円柱状の取付孔１３が形成されており、取付孔１３の周方向の一箇所には、その開口から取付孔１３の約半分の深さにまで至る一定幅のキー溝１４が形成されている。 FIG. 1 is an exploded perspective view of a vehicle shift knob (hereinafter simply referred to as a shift knob). The shift knob includes a main body 1, a sheath member 2, and a lower cover 3, and is attached to the tip of the lever shaft 4. In this embodiment, the shift knob body 1 is a ceramic baked product, and has a rotating object shape of an axial object with a distal end 11 being a curved surface and a proximal end 12 being a flat surface (FIGS. 2 and 3). Note that the shift knob body 1 may be formed of rigid foamed urethane or wood. The shift knob body 1 is formed with a columnar mounting hole 13 that opens to the base end 12 at the center of the shaft. At one place in the circumferential direction of the mounting hole 13, a depth approximately half of the mounting hole 13 from the opening. A key groove 14 having a constant width is formed.

鞘部材２は本実施形態では耐歪性に優れた６−ナイロン樹脂製で、図４に示すように全体が先端閉鎖の円筒状に成形され、先端部２１では径が縮小している。鞘部材２の中間部２２内周には先端部２１との境界に至る間にネジ部２２１が形成されている。また、鞘部材２の基端部２３には、径方向外方へ突出し鞘部材２の外周面と直交する平面状のストッパ面２４ａを形成したストッパ壁２４が形成されるとともに、鞘部材２の基端開口外周には全周に係止壁２５が突出形成されている。また、基端開口の開口縁には周方向の一箇所に、筒軸方向へ突出させて矩形の回転規制壁２６が形成されている。さらに、鞘部材２の基端部２３に近い中間部２２外周には周方向の一箇所に、一定高さのキー２２２が突出形成されている。 In this embodiment, the sheath member 2 is made of 6-nylon resin having excellent strain resistance, and as shown in FIG. 4, the entire sheath member 2 is formed in a cylindrical shape with a closed tip, and the diameter of the tip portion 21 is reduced. A screw part 221 is formed on the inner periphery of the intermediate part 22 of the sheath member 2 while reaching the boundary with the tip part 21. Further, the base end portion 23 of the sheath member 2 is formed with a stopper wall 24 that protrudes radially outward and forms a planar stopper surface 24 a that is orthogonal to the outer peripheral surface of the sheath member 2. A locking wall 25 protrudes from the outer periphery of the base end opening. In addition, a rectangular rotation restricting wall 26 is formed on the opening edge of the base end opening at one location in the circumferential direction so as to protrude in the cylinder axis direction. Furthermore, a key 222 having a constant height is formed to protrude at one place in the circumferential direction on the outer periphery of the intermediate portion 22 near the base end portion 23 of the sheath member 2.

ロアカバー３は樹脂製の円筒体で、一端３１はシフトノブ基端１２の外径にほぼ等しい大径の開口となり、他端３２はレバーシャフト４の外径にほぼ等しい小径の開口となっている。ロアカバー３の、一端３１に向けて漸次拡大する筒内には周方向の三箇所に三角状の係止壁３３（図５参照）が形成されており、係止壁３３にはその内端面の上部に係止凹所３３１が形成されている。 The lower cover 3 is a resin cylindrical body. One end 31 is a large-diameter opening substantially equal to the outer diameter of the shift knob base end 12, and the other end 32 is a small-diameter opening substantially equal to the outer diameter of the lever shaft 4. In the cylinder that gradually expands toward the one end 31 of the lower cover 3, triangular locking walls 33 (see FIG. 5) are formed at three locations in the circumferential direction. A locking recess 331 is formed in the upper part.

鞘部材２は図３に示すようにそのキー２２２をシフトノブ本体１のキー溝１４に合致させて当該本体１の取付孔１３内に挿入され（図５）、その外周面がエポキシ樹脂系の弾性接着剤によって取付孔１３の内周面に接合される。この状態で、キー溝１４内に進入させたキー２２２によって鞘部材２の軸周りの回転変位は規制されている。鞘部材２の挿入量は、ストッパ壁２４のストッパ面２４ａ（図４）が取付孔１３開口部のシフトノブ本体基端１２面に当接することによって制限され、鞘部材２の先端部１２と取付孔１３の内端との間には一定の空間Ｓが形成されて、余剰の弾性接着剤が貯留される。 As shown in FIG. 3, the sheath member 2 is inserted into the mounting hole 13 of the main body 1 with the key 222 aligned with the key groove 14 of the shift knob main body 1 (FIG. 5). It is joined to the inner peripheral surface of the mounting hole 13 by an adhesive. In this state, the rotational displacement around the axis of the sheath member 2 is restricted by the key 222 that has entered the key groove 14. The amount of insertion of the sheath member 2 is limited by the stopper surface 24a (FIG. 4) of the stopper wall 24 coming into contact with the shift knob main body base end 12 surface of the opening of the mounting hole 13, and the distal end portion 12 of the sheath member 2 and the mounting hole A fixed space S is formed between the inner ends of the 13 and excess elastic adhesive is stored.

レバーシャフト４（図１）に予めロアカバー３を嵌入させた後、レバーシャフト４の先端部４１を、ロアカバー３内を通して鞘部材２内に相対進入させ、先端部４１外周に形成されたネジ部４１１を鞘部材２の内周に形成されたネジ部２２１（図５）に結合する。進入したレバーシャフト４の先端部４１によって鞘部材２の先端部２１が押し拡げられ、この時生じる食い込みトルクによってレバーシャフト４に対するシフトノブ本体１の相対回転が防止される。なお、鞘部材先端部２１の拡大変形は、弾性接着剤と、シフトノブ本体１の取付孔１３内の空間Ｓとで保証されている。その後、レバーシャフト４に沿ってシフトノブ本体１の基端１２に向けてロアカバー３を押し上げると、ロアカバー３の係止壁３３に形成された係止凹所３３１が、シフトノブ本体１の基端１２から露出している鞘部材２の係止壁２５に嵌合してこれに結合される。この時、鞘部材２の回転規制壁２６が、ロアカバー３の隣り合った係止壁３３の間に相対的に進入して、ロアカバー３の軸周りの変位が規制される。このようにして、本実施形態の車両用シフトノブによれば、陶磁器や発泡ウレタン等で成形されたシフトノブ本体１をレバーシャフト４に簡易に組み付けることができる。 After the lower cover 3 is fitted in the lever shaft 4 (FIG. 1) in advance, the distal end portion 41 of the lever shaft 4 is relatively advanced into the sheath member 2 through the lower cover 3, and a screw portion 411 formed on the outer periphery of the distal end portion 41. Is coupled to a screw portion 221 (FIG. 5) formed on the inner periphery of the sheath member 2. The distal end portion 21 of the sheath member 2 is pushed and expanded by the distal end portion 41 of the lever shaft 4 that has entered, and relative rotation of the shift knob body 1 with respect to the lever shaft 4 is prevented by the biting torque generated at this time. The expansion deformation of the sheath member distal end portion 21 is ensured by the elastic adhesive and the space S in the mounting hole 13 of the shift knob body 1. Thereafter, when the lower cover 3 is pushed up along the lever shaft 4 toward the base end 12 of the shift knob body 1, the locking recess 331 formed in the locking wall 33 of the lower cover 3 is moved from the base end 12 of the shift knob body 1. The exposed engaging wall 25 of the sheath member 2 is fitted and coupled thereto. At this time, the rotation restricting wall 26 of the sheath member 2 relatively enters between the adjacent locking walls 33 of the lower cover 3 and the displacement around the axis of the lower cover 3 is restricted. Thus, according to the vehicle shift knob of the present embodiment, the shift knob body 1 formed of ceramics, urethane foam or the like can be easily assembled to the lever shaft 4.
