シフトレバー装置Shift lever device
　本発明は、操作レバーが前後左右に揺動し、主にマニュアルトランスミッション（ＭＴ）に適用されるシフトレバー装置に関する。 The present invention relates to a shift lever device that is mainly applied to a manual transmission (MT), with an operating lever swinging back and forth and left and right.
　図７は、特許文献１に開示された、マニュアルトランスミッション（ＭＴ）用のシフトレバー装置１０１の構成を示す。シフトレバー装置１０１では、操作レバー１０２がシフト（車両前後）方向とセレクト（車両左右）方向に揺動可能に支持される。 FIG. 7 shows a configuration of a shift lever device 101 for manual transmission (MT) disclosed in Patent Document 1. In the shift lever device 101, an operation lever 102 is supported so as to be swingable in a shift (vehicle front-rear) direction and a select (vehicle left-right) direction.
　シフトレバー装置１０１は、車体に固定されるベースブラケット（図示せず）に支持体１０３を備える。操作レバー１０２は、シフト（車両前後）方向とセレクト（車両左右）方向に揺動可能に支持体１０３に支持される。 The shift lever device 101 includes a support 103 on a base bracket (not shown) fixed to the vehicle body. The operation lever 102 is supported by the support 103 so as to be swingable in the shift (vehicle front-rear) direction and the select (vehicle left-right) direction.
　操作レバー１０２には、セレクト軸１０９が設けられる。セレクト軸１０９は、操作レバー１０２の軸方向に直交する。セレクト軸１０９の一端には球状部１４１が形成され、セレクト軸１０９の他端には球状部１６２が形成される。球状部１４１は、支持体１０３と補助部材１０３ａとの間に挟持される。球状部１４１は、支持体１０３と補助部材１０３ａとを固定ボルト１０３ｂで固定することで、支持体１０３の球状凹部１０３ｃに回転可能に嵌装される。また、球状部１６２は、支持体１０３に軸支されるセレクトレバー１０５に嵌装される。 The operation lever 102 is provided with a select shaft 109. The select shaft 109 is orthogonal to the axial direction of the operation lever 102. A spherical portion 141 is formed at one end of the select shaft 109, and a spherical portion 162 is formed at the other end of the select shaft 109. The spherical portion 141 is sandwiched between the support 103 and the auxiliary member 103a. The spherical portion 141 is rotatably fitted in the spherical concave portion 103c of the support body 103 by fixing the support body 103 and the auxiliary member 103a with the fixing bolt 103b. Further, the spherical portion 162 is fitted to the select lever 105 that is pivotally supported by the support body 103.
　連係部材（図示せず）はトランスミッション（図示せず）から延設され、操作レバー１０２に連係されている。操作レバー１０２を操作すると、連係部材が変位して、トランスミッションが切り替わる。 A linkage member (not shown) extends from a transmission (not shown) and is linked to the operation lever 102. When the operation lever 102 is operated, the linkage member is displaced, and the transmission is switched.

It is.
　以上の本実施形態によれば、シフトレバー装置１を組立てる際に、軸受ユニット４、操作レバー２、セレクトレバー５、および固定部材７をベースブラケット３に全て同じ方向から順に組付けできることによって、工程毎にベースブラケット３の向きを変える必要がないため、組付作業性を改善できる。 According to the above-described embodiment, when the shift lever device 1 is assembled, the bearing unit 4, the operation lever 2, the select lever 5, and the fixing member 7 can be assembled to the base bracket 3 in order from the same direction. Since it is not necessary to change the direction of the base bracket 3 every time, the assembling workability can be improved.
　軸受の係止爪４２ｄをベースブラケット３の軸支部３２に形成された係合部３２ｂに係合し、軸受ユニット４を軸支部３２に配置する構成とすることで、軸受ユニット４を１工程でベースブラケット３に組付けることができるため、組付作業性を改善することができる。また、このような構成によって、従来のようにベースブラケット、補助部材、固定ボルトでベースブラケット側球状部を固定する必要が無くなるため、さらに部品点数を削減できる。 By engaging the engaging claw 42d of the bearing with the engaging portion 32b formed on the shaft support portion 32 of the base bracket 3 and arranging the bearing unit 4 on the shaft support portion 32, the bearing unit 4 can be arranged in one step.

Further, with such a configuration, it is not necessary to fix the base bracket side spherical portion with the base bracket, the auxiliary member, and the fixing bolt as in the conventional case, so that the number of parts can be further reduced.
　弾性材からなるＯリング４３が軸受ユニット４とベースブラケット３との間に配置される構成とすることで、軸受ユニット４とベースブラケット３とのガタ付きが防止される。このため、係止爪によって軸受を固定する構成であってもガタ付きを生じることがない。 By setting the O-ring 43 made of an elastic material between the bearing unit 4 and the base bracket 3, rattling between the bearing unit 4 and the base bracket 3 is prevented. For this reason, even if it is the structure which fixes a bearing with a latching claw, it does not produce backlash.
　球状凸部６２を係合受部６１内に挿通し、操作支持軸９の支持部９２を枢支する構成とすることで、締結手段が不要となるとともに、係合受部６１が貫通する方向への操作支持軸９の変位を吸収しつつ、枢支できるので、構成を簡素化し、部品点数の削減が図れるとともに、組付作業性を改善できる。 By inserting the spherical convex portion 62 into the engagement receiving portion 61 and pivotally supporting the support portion 92 of the operation support shaft 9, no fastening means is required and the direction in which the engagement receiving portion 61 penetrates is provided. Since it can be pivotally supported while absorbing the displacement of the operation support shaft 9, the structure can be simplified, the number of parts can be reduced, and the assembly workability can be improved.
　固定部材７に形成した係止爪７１ａをベースブラケット３の固定部材受部３４に係合させることで固定部材７をベースブラケット３に組付ける構成とすることで、固定部材７を１工程でベースブラケット３に組付けることができるため、組付作業性を改善することができる。また、このような構成によって、締結手段が不要となるため、部品点数の削減が図れるとともに、さらに組付作業性を改善できる。 By engaging the locking claw 71 a formed on the fixing member 7 with the fixing member receiving portion 34 of the base bracket 3, the fixing member 7 is assembled to the base bracket 3. Since it can assemble | attach to the bracket 3, an assembly workability | operativity can be improved. Further, with such a configuration, the fastening means becomes unnecessary, so that the number of parts can be reduced and the assembling workability can be further improved.
　支持部９１に脆弱部９１ａを設ける構成とすることで、操作レバーに所定方向の倒れ等が作用した際には、脆弱部９１ａが破断することで、乗員に掛かる衝撃を和らげることができるとともに、破断荷重を容易にコントロールすることができる。 By adopting a configuration in which the fragile portion 91a is provided on the support portion 91, when the tilting of the predetermined direction acts on the operation lever, the fragile portion 91a is broken, so that the impact applied to the occupant can be eased, The breaking load can be easily controlled.
　なお、本実施形態では、円柱状の突出軸８１と突出軸８２とからなるセレクトレバー支持軸８が、丸孔状のセレクトレバー軸受部５１に挿通され、セレクトレバー５を軸支する構成としているが、ベースブラケット３において突出軸８１が設けられる箇所に丸孔を形成し、固定部材７において突出軸８２が設けられる箇所に丸孔を形成し、円柱状のセレクトレバー軸受部５１をこれらの丸孔に挿通し、セレクトレバー５を軸支する構成としてもよい。この場合も上記の実施形態と同様の作用効果が得られる。 In the present embodiment, the select lever support shaft 8 including the columnar projecting shaft 81 and the projecting shaft 82 is inserted into the round hole-shaped select lever bearing portion 51 to support the select lever 5. However, a round hole is formed at a location where the projecting shaft 81 is provided in the base bracket 3, and a round hole is formed at a location where the projecting shaft 82 is provided in the fixing member 7. It is good also as a structure which inserts in a hole and supports the select lever 5 pivotally. In this case, the same effect as the above embodiment can be obtained.
　また、セレクトレバー５の軸支部をベースブラケット３の円柱状突出軸８１のみで構成し、ベースブラケット３のレバー受部３３だけでセレクトレバー５を軸支してもよい。この場合、図６に示すように、突出軸８１（セレクトレバー支持軸８）は、セレクトレバー軸受部５１の幅と同じ長さを有し、その中心に貫通孔８１ａが形成される。貫通孔８１ａは、突出軸８１の軸方向に延伸するように形成される。貫通孔８１ａには固定部材１７が挿通され、突出軸８１と嵌合する。固定部材１７は、セレクトレバー軸受部５１の孔径よりも大きい直径を有する円盤状の鍔部１７ａと、鍔部１７ａの中心から、垂直に突出する中空の円筒部１７ｂとを有する。円筒部１７ｂは、円筒部１７ｂが摺動しながら貫通孔８１ａに挿通できる程度の直径をもつ。円筒部１７ｂの側面には、スリット１７ｃが少なくとも２箇所に形成される。スリット１７ｃは、円筒部１７ｂの先端から鍔部１７ａに向けて形成され、円筒部１７ｂの側面を分割する。その結果、分割された各側面は、円筒部１７ｂの中心軸に向けて弾性的に撓むことが可能なアームとして機能する。スリット１７ｃによって分割された各側面の先端には爪部１７ｄが形成されている。爪部１７ｄは、突出軸８１におけるベースブラケット３側の端縁に係止し、貫通孔８１ａに挿通した円筒部１７ｂが抜け出るのを防止する。突出軸８１は、上記の実施形態と同様に、セレクトレバー軸受部５１に挿通される。その後、固定部材１７の円筒部１７ｂが突出軸８１の貫通孔８１ａに挿通される。円筒部１７ｂが貫通孔８１ａに完全に挿通されると、爪部１７ｄが突出軸８１の端縁に係止し、鍔部１７ａがセレクトレバー軸受部５１の側面と、突出軸８１の先端に当接する。従って、固定部材１７は、貫通孔８１ａから抜け出ることが規制された状態で、セレクトレバー軸受部５１が突出軸８１から抜け出ることを防止する。これにより、セレクトレバー５は、突出軸８１によって安定に軸支される。この場合も上記の実施形態と同様の作用効果が得られる。 Alternatively, the shaft support portion of the select lever 5 may be constituted only by the cylindrical protruding shaft 81 of the base bracket 3, and the select lever 5 may be pivotally supported only by the lever receiving portion 33 of the base bracket 3.

The fixing member 17 includes a disc-shaped flange portion 17a having a diameter larger than the hole diameter of the select lever bearing portion 51, and a hollow cylindrical portion 17b protruding vertically from the center of the flange portion 17a. The cylindrical portion 17b has a diameter that allows the cylindrical portion 17b to be inserted into the through hole 81a while sliding. At least two slits 17c are formed on the side surface of the cylindrical portion 17b. The slit 17c is formed from the tip of the cylindrical portion 17b toward the flange portion 17a, and divides the side surface of the cylindrical portion 17b. As a result, each divided side surface functions as an arm that can be elastically bent toward the central axis of the cylindrical portion 17b.
