　上記シフトレバー装置１０１では、セレクトレバー１０４でセレクトケーブルを押引きするには、連係軸１３４はある程度の長さを有していなければならない。また、レバー軸１０３のセレクト方向への操作力は、連係軸１３４の基端に作用する。従って、連係軸１３４を金属で形成すると共に、連係軸１３４を金属製のレバー軸１０３に溶接して、十分な強度を確保する必要がある。しかし、連係軸１３４を金属で形成し、かつ、溶接を行なうと、製造コストや装置重量が増加してしまう。 In the shift lever device 101, in order to push and pull the select cable with the select lever 104, the linkage shaft 134 must have a certain length. Further, the operating force in the select direction of the lever shaft 103 acts on the proximal end of the linkage shaft 134. Therefore, it is necessary to secure the sufficient strength by forming the linkage shaft 134 from metal and welding the linkage shaft 134 to the metal lever shaft 103. However, if the linkage shaft 134 is formed of metal and welding is performed, the manufacturing cost and the weight of the apparatus increase.

A base bracket that pivotally supports the shaft support portion, wherein the lever shaft has a base portion formed of resin on one end side of the metal rod, and the shaft support portion is integrally formed on one side surface of the base portion. Provided is a shift lever device in which a linkage shaft extending along the select direction and a linkage spherical portion formed at a tip end portion of the linkage shaft are integrally formed on the other side surface of the base portion. To do.
　上記特徴によれば、軸支持部及び連係球状部の長さを変えることなく、連係軸の長さを短くできるので、連係軸及び連係球状部は、樹脂で形成されても十分な強度を有する。 According to the above feature, since the length of the linkage shaft can be shortened without changing the length of the shaft support portion and the linkage spherical portion, the linkage shaft and the linkage spherical portion have sufficient strength even when formed of resin. .
　ここで、上記シフトレバー装置が、前記レバー軸の前記基部の下端に設けられ、前記レバー軸の前記シフト方向の揺動に伴って前記シフト方向に揺動される連係腕部と、前記シフト方向に沿って揺動可能に、前記ベースブラケットに軸支されたセレクトレバーとをさらに備えており、前記連係腕部が、前記レバー軸の前記セレクト方向に沿う前記連係軸とは反対側への揺動時に前記セレクトレバーと平行となるように、前記レバー軸の上部に対して屈曲されて、前記レバー軸の下部に延設されている、ことが好ましい。 Here, the shift lever device is provided at a lower end of the base portion of the lever shaft, and is a linkage arm portion that swings in the shift direction as the lever shaft swings in the shift direction, and the shift direction And a select lever pivotally supported by the base bracket so that the link arm portion swings to the opposite side of the link shaft along the select direction of the lever shaft. It is preferable that the lever is bent with respect to the upper portion of the lever shaft and extends to the lower portion of the lever shaft so as to be parallel to the select lever when moving.
　このようにすれば、連係腕部とセレクトレバーとの干渉を防止しつつ、レバー軸とセレクトレバーとを近接配置することができる。従って、連係軸の長さを短くでき、連係軸の強度をさらに向上できる。 In this way, the lever shaft and the select lever can be arranged close to each other while preventing interference between the linkage arm portion and the select lever. Therefore, the length of the linkage shaft can be shortened, and the strength of the linkage shaft can be further improved.
　また、前記連係軸の基台部が、前記レバー軸側が広く、かつ、前記連係球状部側が狭い台形形状を有している、ことが好ましい。 Further, it is preferable that the base portion of the linkage shaft has a trapezoidal shape that is wide on the lever shaft side and narrow on the linkage spherical portion side.
　このようにすれば、セレクトレバーによって連係球状部の回転摺動が妨げられることなく、連係軸の強度をさらに向上できる。 In this way, the strength of the linkage shaft can be further improved without hindering the sliding movement of the linkage spherical portion by the select lever.

　軸支持部１１は、球状凸部３３と軸受部材５とで構成されている。球状凸部３３が球状凹部５１に組付けられた状態で、軸受部材５を軸受収容部２２に組付けることで、球状凸部３３がベースブラケット２に枢支される。なお、球状凸部３３の曲率は、球状凹部５１の曲率よりわずかに大きく設定されている。このため、軸受部材５（球状凹部５１）がレバー軸３（球状凸部３３）に組付けられると、球状凸部３３は、軸受部材５に対してガタ付くことなく、回転摺動可能に枢支される。なお、軸受部材５は、軸受固定構造１２によって、軸受収容部２２内に保持される。 The shaft support portion 11 is composed of a spherical convex portion 33 and a bearing member 5. The spherical convex portion 33 is pivotally supported by the base bracket 2 by assembling the bearing member 5 to the bearing housing portion 22 in a state where the spherical convex portion 33 is assembled to the spherical concave portion 51. Note that the curvature of the spherical convex portion 33 is set to be slightly larger than the curvature of the spherical concave portion 51. For this reason, when the bearing member 5 (spherical concave portion 51) is assembled to the lever shaft 3 (spherical convex portion 33), the spherical convex portion 33 is pivotably slidable without rattling with respect to the bearing member 5. Be supported. The bearing member 5 is held in the bearing housing portion 22 by the bearing fixing structure 12.
　軸受固定構造１２は、係止段部２２ｄと弾性爪部５３とで構成されている。軸受部材５を軸受収容部２２に挿入すると、弾性爪部５３が係止溝２２ｃに挿入され、組付位置で係止段部２２ｄと係止爪５３ｂとが係合する。係止段部２２ｄと係止爪５３ｂとの係合によって、軸受部材５が軸受収容部２２内に保持される。 The bearing fixing structure 12 includes a locking step portion 22d and an elastic claw portion 53. When the bearing member 5 is inserted into the bearing housing portion 22, the elastic claw portion 53 is inserted into the locking groove 22c, and the locking step portion 22d and the locking claw 53b are engaged at the assembly position. The bearing member 5 is held in the bearing housing portion 22 by the engagement between the locking step portion 22d and the locking claw 53b.
　圧入リブ５７は、スリット５４によって六分割された筒壁５２のうち、二つの弾性爪部５３が配置されていない四つの筒壁５２の外周面上の中央に、軸方向に沿って尾根状に形成されている。軸受部材５が軸受収容部２２内に組付けられると、圧入リブ５７が潰れる方向に弾性変形する。圧入リブ５７の復元力によって、側壁２２ａと筒壁５２の間の径方向の隙間が無くなり、ガタ付きが抑制される。 The press-fitting rib 57 has a ridge shape along the axial direction at the center on the outer peripheral surface of the four cylindrical walls 52 where the two elastic claws 53 are not arranged among the cylindrical walls 52 divided into six by the slit 54. Is formed. When the bearing member 5 is assembled in the bearing housing portion 22, it is elastically deformed in the direction in which the press-fit rib 57 is crushed. The restoring force of the press-fitting rib 57 eliminates the radial gap between the side wall 22a and the cylindrical wall 52, thereby suppressing backlash.
　レバー支持部１４は、セレクトレバー４を車両縦方向に揺動可能な状態でベースブラケット２に支持する。レバー支持部１４は、支持筒２３、セレクト軸孔４１、及び、支持ピン６１で構成されている。支持ピン６１は、丸棒状のピン軸[pin shaft]６１ａと、ピン軸６１ａの一端に形成された円盤状のピンフランジ[pin flange]６１ｂと、ピン軸６１ａの他端に二股状に形成された可撓性のピン係合部６１ｃとを備えている。ピン係合部６１ｃの先端には、支持筒２３の筒孔[cylindrical hole]２３ａ内に係合する爪[claws]６１ｄが形成されている。 The lever support portion 14 supports the select lever 4 on the base bracket 2 in a state where the select lever 4 can swing in the longitudinal direction of the vehicle. The lever support portion 14 includes a support cylinder 23, a select shaft hole 41, and a support pin 61. The support pin 61 is formed in a bifurcated shape at the other end of the pin shaft 61a, a round pin-shaped pin shaft [pin shaft] 61a, a disk-shaped pin flange [pin flange] 61b formed at one end of the pin shaft 61a. And a flexible pin engaging portion 61c. At the tip of the pin engaging portion 61c, a claw 61d that engages in a cylindrical hole 23a of the support cylinder 23 is formed.
　支持筒２３をセレクト軸孔４１に挿通させることで、セレクトレバー４が回動可能に支持される。また、支持筒２３の筒孔２３ａ内に支持ピン６１が挿入され、爪６１ｄが筒孔２３ａ内に係合される。この結果、支持ピン６１が支持筒２３に係止され、ピンフランジ６１ｂによってセレクトレバー４の軸方向の移動が規制される。その一方で、セレクトレバー４は、支持筒２３周りの回動が許容された状態で軸支される。 セ レ ク ト By inserting the support cylinder 23 into the select shaft hole 41, the select lever 4 is rotatably supported. Further, the support pin 61 is inserted into the tube hole 23a of the support tube 23, and the claw 61d is engaged with the tube hole 23a. As a result, the support pin 61 is locked to the support cylinder 23, and the axial movement of the select lever 4 is restricted by the pin flange 61b. On the other hand, the select lever 4 is pivotally supported in a state where the rotation around the support cylinder 23 is allowed.
　連係部１５は、レバー軸３のセレクト方向（車両横方向）の揺動を車両縦方向の揺動に変換する。連係部１５は、連係球状部３５及び連係受部４２で構成されている。連係球状部３５は、球状凸部３３を中心として円弧状に移動し、連係受部４２内に摺動可能に隙間無く挿通される。レバー軸３のセレクト方向の揺動によって、連係球状部３５は、球状凸部３３を中心として上下方向に揺動される。そして、連係球状部３５の上下方向の揺動によって、セレクトレバー４は、支持筒２３を中心として前後方向に揺動する。この結果、セレクトケーブル連係部４３が前後方向に沿って移動する。 The linkage unit 15 converts the rocking of the lever shaft 3 in the select direction (vehicle lateral direction) into the vehicle vertical rocking. The linking unit 15 includes a linking spherical portion 35 and a linking receiving unit 42. The linking spherical portion 35 moves in an arc shape around the spherical convex portion 33 and is slidably inserted into the linking receiving portion 42 without a gap. As the lever shaft 3 swings in the select direction, the associated spherical portion 35 swings in the vertical direction around the spherical convex portion 33. The select lever 4 swings in the front-rear direction around the support cylinder 23 by the swinging of the linkage spherical portion 35 in the vertical direction. As a result, the select cable link portion 43 moves along the front-rear direction.
　シフトレバー装置１を組立てる手順を説明する。まず、レバー軸３の球状凸部３３が軸受部材５に組付けられる。球状凸部３３を軸受部材５に組付けるには、球状凸部３３を、一側端面５２ｂの側（反挿入側：軸受部材５の軸受収容部２２への挿入側の反対側：図１中の右側）から軸受部材５に押込む。このとき、スリット５４が拡げられて筒壁５２が拡径方向に撓み、球状凸部３３が球状凹部５１内に収容されると筒壁５２が元の形状に復帰する。 The procedure for assembling the shift lever device 1 will be described. First, the spherical convex portion 33 of the lever shaft 3 is assembled to the bearing member 5. In order to assemble the spherical convex portion 33 to the bearing member 5, the spherical convex portion 33 is arranged on one side end surface 52 b side (anti-insertion side: opposite side to the insertion side of the bearing member 5 into the bearing accommodating portion 22: in FIG. 1. From the right side) into the bearing member 5. At this time, when the slit 54 is expanded and the cylindrical wall 52 bends in the diameter increasing direction and the spherical convex portion 33 is accommodated in the spherical concave portion 51, the cylindrical wall 52 returns to its original shape.
　次に、レバー軸３と共に、軸受部材５がベースブラケット２の軸受収容部２２に組付けられる。軸受部材５を軸受収容部２２に組付けるには、軸受部材５を、他側端面５２ａ側から軸受収容部２２に押込む。この結果、弾性爪部５３が係止溝２２ｃに沿って撓み、組付位置で係止爪５３ｂが係止段部２２ｄと係合して、軸受部材５が軸受収容部２２内に保持される。このとき、圧入リブ５７が潰れる方向に弾性変形して、圧入リブ５７の復元力によって軸受部材５の径方向のガタが吸収される。 Next, the bearing member 5 is assembled together with the lever shaft 3 into the bearing accommodating portion 22 of the base bracket 2. In order to assemble the bearing member 5 to the bearing housing portion 22, the bearing member 5 is pushed into the bearing housing portion 22 from the other end face 52 a side. As a result, the elastic claw portion 53 bends along the locking groove 22c, the locking claw 53b engages with the locking step portion 22d at the assembly position, and the bearing member 5 is held in the bearing housing portion 22. . At this time, the press-fit ribs 57 are elastically deformed in the direction in which they are crushed, and the backlash in the radial direction of the bearing member 5 is absorbed by the restoring force of the press-fit ribs 57.
　次に、セレクトレバー４がベースブラケット２に組付けられる。セレクトレバー４をベースブラケット２に組付けるには、支持筒２３をセレクト軸孔４１に挿入しつつ、連係球状部３５を連係受部４２に挿入する。最後に、支持ピン６１が支持筒２３の筒孔２３ａに挿入され、組付け作業が完了する。 Next, the select lever 4 is assembled to the base bracket 2. To attach the select lever 4 to the base bracket 2, the connecting spherical portion 35 is inserted into the connecting receiving portion 42 while the support cylinder 23 is inserted into the select shaft hole 41. Finally, the support pin 61 is inserted into the tube hole 23a of the support tube 23, and the assembly work is completed.
　なお、レバー軸３及び軸受部材５をベースブラケット２に組付ける方向、セレクトレバー４をベースブラケット２に組付ける方向、及び、支持ピン６１を支持筒２３に組付ける方向は、全て同じ方向（図１中の右から左）に設定されている。 The direction in which the lever shaft 3 and the bearing member 5 are assembled to the base bracket 2, the direction in which the select lever 4 is assembled to the base bracket 2, and the direction in which the support pin 61 is assembled to the support cylinder 23 are all the same direction (see FIG. 1 from right to left).
　以上の構成によって、運転者がレバー軸３をシフト方向に揺動させると、シフトケーブルは押引きされる。運転者がレバー軸３をセレクト方向に揺動させると、セレクトレバー４がシフト方向に揺動されて、セレクトケーブルが押引きされる。 With the above configuration, when the driver swings the lever shaft 3 in the shift direction, the shift cable is pushed and pulled. When the driver swings the lever shaft 3 in the select direction, the select lever 4 swings in the shift direction and the select cable is pushed and pulled.
　本実施形態のレバー軸３では、金属棒３ａの一端側に樹脂によって基部３ｂが一体的に形成され、この基部３ｂの一側面に軸支持部１１の球状凸部３３が一体的に形成されると共に他側面に連係軸３４及び連係球状部３５が一体的に形成されている。従って、球状凸部３３及び連係球状部３５の長さを変えることなく連係軸３４の長さを短くできるので、球状凸部３３、連係軸３４及び連係球状部３５は、樹脂で形成されても十分な強度を有する。また、球状凸部３３、連係軸３４及び連係球状部３５を樹脂成形で形成するので、溶接等の追加加工が不要であり、製造コストを削減でき、かつ、軽量化できる。 In the lever shaft 3 of the present embodiment, a base 3b is integrally formed on one end side of the metal rod 3a with resin, and a spherical convex portion 33 of the shaft support portion 11 is integrally formed on one side surface of the base 3b. In addition, the linkage shaft 34 and the linkage spherical portion 35 are integrally formed on the other side. Accordingly, since the length of the linkage shaft 34 can be shortened without changing the length of the spherical projection 33 and the linkage spherical portion 35, the bulbous projection 33, the linkage shaft 34, and the linkage spherical portion 35 can be formed of resin. It has sufficient strength. Further, since the spherical convex portion 33, the linkage shaft 34, and the linkage spherical portion 35 are formed by resin molding, no additional processing such as welding is required, and the manufacturing cost can be reduced and the weight can be reduced.
　また、レバー軸３の下部に、レバー軸３の上部に対して連係軸３４とは反対側に屈曲された連係腕部３６が延設されているので、連係腕部３６とセレクトレバー４との干渉を防止しつつ、レバー軸３とセレクトレバー４とを近接配置することができる。従って、連係軸３４の長さを短くでき、連係軸３４の強度をさらに向上できる。さらに、連係軸３４は、台形形状を有するように形成されるので、セレクトレバー４によって連係球状部３５の回転摺動が妨げられることなく、連係軸３４の強度をさらに向上できる。 In addition, since the linkage arm portion 36 that is bent to the opposite side of the linkage shaft 34 with respect to the upper portion of the lever shaft 3 is extended at the lower portion of the lever shaft 3, the linkage arm portion 36 and the select lever 4 are connected to each other. The lever shaft 3 and the select lever 4 can be arranged close to each other while preventing interference. Therefore, the length of the linkage shaft 34 can be shortened, and the strength of the linkage shaft 34 can be further improved. Furthermore, since the linkage shaft 34 is formed to have a trapezoidal shape, the strength of the linkage shaft 34 can be further improved without hindering the rotation and sliding of the linkage spherical portion 35 by the select lever 4.
　なお、本実施形態では、樹脂によって形成された基部３ｂに一体的に球状凸部３３及び連係球状部３５が形成された。しかし、球状凸部３３や連係球状部３５を樹脂によって中実に形成すると、「ひけ[sink]」によって形状精度が悪くなる場合がある。このため、図４に示されるように、球状凸部３３Ａや連係球状部３５Ａに複数の肉抜き部[volume-reducing cutout portions]３３ｅ及び３５ｅが形成されても良い。 In addition, in this embodiment, the spherical convex part 33 and the connection spherical part 35 were integrally formed in the base 3b formed with resin. However, when the spherical convex portion 33 and the connecting spherical portion 35 are solidly formed of resin, the shape accuracy may deteriorate due to “sink”. For this reason, as shown in FIG. 4, a plurality of cut-out portions [volume-reducing cutout portions] 33e and 35e may be formed on the spherical convex portion 33A or the linked spherical portion 35A.
