Description

【０００１】
【発明の属する技術分野】
本発明は、車両用変速機の変速操作を行うためのシフトレバーに関するものである。
【０００２】
【従来の技術】
従来、この種のシフトレバーとして、図３に示すように、基端が車体に枢着されたシャフト２の先端に雄ねじ部２ｄが形成され、ノブ表皮部材３に形成された穴３ａをシャフト２の先端に嵌入することによりノブ表皮部材３がシャフト２の先端に取付けられ、雄ねじ部２ｄに螺合可能な雌ねじ部５ａを有するノブインサート部材５がノブ表皮部材３の穴３ａ及びシャフト２間に介装され、ノブ表皮部材３の下方に位置するようにシャフト２にブーツ固定部材４が嵌入され、更にブーツ６の一端がブーツ固定部材４に取付けられたシフトレバーが知られている。このシフトレバー１では、ブーツ６がその他端に向うに従って次第に広がって形成され、このブーツ６によりシャフト２の外周面が覆われる。またシャフト２は可倒式であって、基端が車体に枢着された第１軸部２ａと、先端にノブ表皮部材３がノブインサート部材５を介して取付けられた第２軸部２ｂと、第２軸部２ｂの基端を第１軸部２ａの先端に枢着するヒンジ部２ｃとを有する。上記ヒンジ部２ｃにはフランジ等の突起部２ｅがシャフト２の半径方向に突出して設けられる。更に第１軸部２ａの周面には凹溝２ｆが形成され、ブーツ固定部材４の内周面には凸部４ａが形成され、凸部４ａが凹溝２ｆに係止することによりブーツ固定部材４が第１軸部２ａに固定される。
【０００３】
【発明が解決しようとする課題】
しかし、上記従来のシフトレバーでは、ノブインサート部材とブーツ固定部材とが別々に形成されているため、部品管理が煩わしく、組付工数が増大する不具合があった。
また、上記従来のシフトレバーでは、ノブ表皮部材を把持して操作すると、上記フランジ等の突起部の先端がブーツと干渉してブーツを損傷するおそれがあった。
本発明の目的は、部品点数及び組付工数を低減できるとともに、ブーツとシャフトの突起部との干渉を防止できる、シフトレバーを提供することにある。
本発明の別の目的は、ブーツの損傷を防止できる、シフトレバーを提供することにある。
【０００４】
【課題を解決するための手段】
請求項１に係る発明は、図１に示すように、基端が車体に枢着され先端に雄ねじ部１２ｄが形成されたシャフト１２と、穴１３ａを有しこの穴１３ａをシャフト１２の先端に嵌入することによりシャフト１２の先端に取付けられるノブ表皮部材１３と、雄ねじ部１２ｄに螺合可能な雌ねじ部１５ａを有しノブ表皮部材１３の穴１３ａ及びシャフト１２間に介装されたノブインサート部材１５と、ノブ表皮部材１３の下方に位置するようにシャフト１２に嵌入されたブーツ固定部材１４と、一端がブーツ固定部材１４に取付けられ他端に向うに従って次第に広がって形成されかつシャフト１２の外周面を覆うブーツ１６とを備えたシフトレバーの改良である。
その特徴ある構成は、ノブインサート部材１５及びブーツ固定部材１４が一体的に成形されかつ前記ノブ表皮部材１３と一体化され、ブーツ固定部材１４がノブ表皮部材１３から離れるに従って次第に広がる円錐台状に形成され、シャフト１２の中央に半径方向に突出する突起部１２ｅが設けられ、ブーツ固定部材１４が平面視で突起部１２ｅを覆うように形成されたところにある。
この請求項１に記載されたシフトレバーでは、ノブインサート部材１５及びブーツ固定部材１４が一体的に成形されるため、部品点数を低減できるので、部品管理を比較的容易に行えるとともに、組付工数を低減できるので、製造コストを低減できる。
またブーツ固定部材１４が平面視で突起部１２ｅを覆うので、ノブ表皮部材１３を把持して操作しても、ブーツ１６が突起部１２ｅに干渉することはない。
【０００６】
【発明の実施の形態】
次に本発明の実施の形態を図面に基づいて説明する。
図１及び図２に示すように、シフトレバー１１は、基端が車体に枢着されたシャフト１２と、穴１３ａを有しこの穴１３ａをシャフト１２の先端に嵌入することによりシャフト１２の先端に取付けられるノブ表皮部材１３と、ノブ表皮部材１３の穴１３ａ及びシャフト１２間に介装されたノブインサート部材１５と、ノブ表皮部材１３の下方に位置するようにシャフト１２に嵌入されたブーツ固定部材１４と、一端がブーツ固定部材１４に取付けられたブーツ１６とを備える。シャフト１２の先端には雄ねじ部１２ｄが形成され、シャフト１２の中央にはこのシャフト１２の半径方向に突出する突起部１２ｅが設けられる（図１）。
【０００７】
シャフト１２は、基端が車体に枢着された第１軸部１２ａと、先端にノブ１３が取付けられた第２軸部１２ｂと、第２軸部１２ｂの基端を第１軸部１２ａの先端に枢着するヒンジ部１２ｃとを有する。上記突起部１２ｅはこのヒンジ部１２ｃの構成物品である。またノブ表皮部材１３は塩化ビニルにより形成される。
【０００８】
ノブインサート部材１５及びブーツ固定部材１４は硬質のポリアミド系合成高分子材料により一体的に成形される。ノブインサート部材１５は、このノブインサート部材１５の中心に形成されたシャフト挿入穴１５ｂと、シャフト挿入穴１５ｂの奥に形成されかつ上記雄ねじ部１２ｄに螺合可能な雌ねじ部１５ａとを有する。ブーツ固定部材１４は、ノブインサート部材１５の下端に連結される連結筒部１４ａと、この連結筒部１４ａの下端に連結されかつノブ表皮部材１３から離れるに従って次第に広がる円錐台状に形成されたスカート部１４ｂとを有する。スカート部１４ｂは平面視で突起部１２ｅを覆うように形成される。
【０００９】
またノブ表皮部材１３によりノブインサート部材１５を被覆することにより、ノブインサート部材１５及びブーツ固定部材１４がノブ表皮部材１３と一体化される。更にブーツ１６の一端は連結筒部１４ａ及びスカート部１４ｂに嵌着され、このブーツ１６によりシャフト１２の外周面が覆われる。即ち、ブーツ１６はスカート部１４ｂの外周面に沿って次第に広がり、更に他端に向うに従って次第に広がるように形成される。
【００１０】
このように構成されたシフトレバー１１では、ノブインサート部材１５とブーツ固定部材１４とを一体的に成形し、ノブ表皮部材１３によりノブインサート部材１５を被覆してノブインサート部材１５及びブーツ固定部材１４をノブ表皮部材１３と一体化した後に、連結筒部１４ａ及びスカート部１４ｂにブーツ１６の一端を嵌着することにより、ノブインサート部材１５及びブーツ固定部材１４がノブ表皮部材１３及びブーツ１６と一体化される。これにより部品点数が減少するので、部品管理が容易になるとともに、組付工数を低減できるので、製造コストを低減できる。またブーツ固定部材１４が平面視でシャフト１２の突起部１２ｅを覆うので、ノブ表皮部材１３を把持して操作しても、ブーツ１６が突起部１２ｅに干渉することはない。この結果、ブーツ１６が突起部１２ｅで擦られないので、ブーツ１６は損傷しない。
【００１１】
【発明の効果】
以上述べたように、本発明によれば、ノブインサート部材及びブーツ固定部材を一体的に成形しかつノブ表皮部材と一体化し、更にブーツ固定部材をノブ表皮部材から離れるに従って次第に広がる円錐台状に形成したので、部品点数を低減できるとともに、組付工数を低減できる。この結果、部品管理を比較的容易に行えるとともに、製造コストを低減できる。
またブーツ固定部材を平面視でシャフトの突起部を覆うように形成すれば、ノブ表皮部材を把持して操作しても、ブーツが突起部に干渉しない。この結果、ブーツが突起部への摩擦等により損傷することはない。

The characteristic structure is that the knob insert member 15 and the boot fixing member 14 are integrally formed and integrated with the knob skin member 13, and the boot fixing member 14 gradually expands as the knob skin member 13 moves away. The protrusion 12e is formed in the center of the shaft 12 and protrudes in the radial direction, and the boot fixing member 14 is formed so as to cover the protrusion 12e in plan view .
In the shift lever according to the first aspect, since the knob insert member 15 and the boot fixing member 14 are integrally formed, the number of parts can be reduced, so that the parts can be managed relatively easily and the assembly man-hours can be reduced. Therefore, the manufacturing cost can be reduced.
Further, since the boot fixing member 14 covers the projection 12e in a plan view, the boot 16 does not interfere with the projection 12e even if the knob skin member 13 is gripped and operated.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the shift lever 11 has a shaft 12 having a base end pivotally attached to the vehicle body and a hole 13 a, and the hole 13 a is fitted into the tip of the shaft 12 to fit the tip of the shaft 12. The knob skin member 13 attached to the knob, the knob insert member 15 interposed between the hole 13a of the knob skin member 13 and the shaft 12, and the boot fixing fitted into the shaft 12 so as to be positioned below the knob skin member 13 A member 14 and a boot 16 having one end attached to the boot fixing member 14 are provided. A male screw portion 12d is formed at the tip of the shaft 12, and a projection 12e protruding in the radial direction of the shaft 12 is provided at the center of the shaft 12 (FIG. 1).
[0007]
The shaft 12 includes a first shaft portion 12a having a base end pivotally attached to the vehicle body, a second shaft portion 12b having a knob 13 attached to the front end, and a base end of the second shaft portion 12b. And a hinge portion 12c pivotally attached to the tip. The protrusion 12e is a component of the hinge 12c. The knob skin member 13 is made of vinyl chloride.
[0008]
The knob insert member 15 and the boot fixing member 14 are integrally formed of a hard polyamide synthetic polymer material. The knob insert member 15 has a shaft insertion hole 15b formed at the center of the knob insert member 15, and a female screw portion 15a formed at the back of the shaft insertion hole 15b and screwable with the male screw portion 12d. The boot fixing member 14 includes a connecting cylinder portion 14a connected to the lower end of the knob insert member 15, and a skirt formed in a truncated cone shape that is connected to the lower end of the connecting cylinder portion 14a and gradually spreads away from the knob skin member 13. Part 14b. The skirt portion 14b is formed so as to cover the protruding portion 12e in plan view.
[0009]
Further, by covering the knob insert member 15 with the knob skin member 13, the knob insert member 15 and the boot fixing member 14 are integrated with the knob skin member 13. Further, one end of the boot 16 is fitted into the connecting cylinder portion 14 a and the skirt portion 14 b, and the outer peripheral surface of the shaft 12 is covered by the boot 16. That is, the boot 16 is formed so as to gradually expand along the outer peripheral surface of the skirt portion 14b and further expand toward the other end.
[0010]
In the shift lever 11 configured as described above, the knob insert member 15 and the boot fixing member 14 are integrally formed, and the knob insert member 15 is covered with the knob skin member 13 so that the knob insert member 15 and the boot fixing member 14 are covered. Is integrated with the knob skin member 13, and then the knob insert member 15 and the boot fixing member 14 are integrated with the knob skin member 13 and the boot 16 by fitting one end of the boot 16 to the connecting cylinder portion 14 a and the skirt portion 14 b. It becomes. Since the number of parts is thereby reduced, parts management becomes easy and the number of assembling steps can be reduced, so that the manufacturing cost can be reduced. Since the boot fixing member 14 covers the projection 12e of the shaft 12 in plan view, the boot 16 does not interfere with the projection 12e even if the knob skin member 13 is gripped and operated. As a result, the boot 16 is not rubbed by the protrusion 12e, so that the boot 16 is not damaged.
[0011]
【The invention's effect】
As described above, according to the present invention, the knob insert member and the boot fixing member are integrally formed and integrated with the knob skin member, and further, the boot fixing member is formed into a truncated cone shape that gradually expands as the distance from the knob skin member increases. Since it formed , the number of parts can be reduced and the number of assembling steps can be reduced. As a result, parts management can be performed relatively easily and the manufacturing cost can be reduced.
Also by forming the boot fixing member so as to cover the protruding portion of the shaft in a flat plane when viewed, be manipulated by gripping the knob skin member, the boot does not interfere with the projections. As a result, the boot is not damaged by friction or the like on the protrusion.
