Description
本発明は、複数のシフトフォークのうち特定のシフトフォークを選択するセレクト操作と、選択された特定のシフトフォークを作動させるシフト操作とにより、所定の変速段への変速を行わせるための変速操作装置に関するものである。
The present invention relates to a shift operation for performing a shift to a predetermined shift stage by a select operation for selecting a specific shift fork among a plurality of shift forks and a shift operation for operating the selected specific shift fork. It relates to the device.
一般的に、自動車等の車両に搭載された変速操作装置は、複数のシフトフォークのうち特定のシフトフォークを選択するセレクト操作と、選択された特定のシフトフォークを作動させるシフト操作とが可能とされており、特定のシフトフォークをシフト操作することで、任意の変速段に対応するドライブギアとドリブンギアとを一体結合させ、その変速段へ変速し得るようになっている。
Generally, a shift operation device mounted on a vehicle such as an automobile can perform a selection operation for selecting a specific shift fork among a plurality of shift forks and a shift operation for operating the selected specific shift fork. Thus, by operating a specific shift fork, a drive gear and a driven gear corresponding to an arbitrary gear stage can be integrally coupled, and the gear can be shifted to that gear stage.
従来の変速操作装置は、例えば特許文献1にて開示されているように、セレクト位置の位置決めとシフト位置の保持を行う機構を有するセレクト装置が設けられており、当該セレクト装置の機構には、固定された軸に対して回転又は摺動可能なセレクトレバーが形成されている。かかる従来の変速操作装置には、その軸側にシフトパターンの如く延設された溝が形成されるとともに、セレクトレバー側にスプリングで当該溝に付勢されたボールが配設されていた。
For example, as disclosed in Patent Document 1, a conventional speed change operation device is provided with a select device having a mechanism for positioning a select position and holding a shift position. The mechanism of the select device includes: A select lever that can rotate or slide with respect to the fixed shaft is formed. In such a conventional speed change operation device, a groove extending like a shift pattern is formed on the shaft side, and a ball urged to the groove by a spring is disposed on the select lever side.
そして、シフト操作に応じてセレクトレバーが軸に対して摺動してセレクト操作される過程、及び軸に対して回転してシフト操作される過程において、ボールが溝に嵌合しつつ案内されるよう構成されていた。これにより、セレクト操作が不完全な状態でシフト操作しようとした場合、ボールが溝から外れてセレクトレバーを回り止めすることで、次のシフト操作ができないようロックすることができる。
Then, the ball is guided while being fitted into the groove in the process in which the select lever slides with respect to the shaft in accordance with the shift operation, and in the process in which the select lever rotates with respect to the shaft. It was configured as follows. As a result, when the shift operation is attempted in a state where the select operation is incomplete, the ball can be removed from the groove and the select lever can be prevented from rotating so that the next shift operation cannot be performed.
しかしながら、上記従来の変速操作装置においては、セレクト操作が不完全な状態でシフト操作しようとした場合、ボールが溝から外れてセレクトレバーを回り止めするので、それ以降のシフト操作を続けて行うことができなくなってしまうという問題があった。すなわち、従来の変速操作装置は、ボールが溝から外れて回り止めを行うことで、セレクト操作が不完全な状態でのシフト操作を規制することができるものの、それ以降にシフト操作を行わせるには、外れたボールを溝に戻す別個の作業が必要とされるのである。
However, in the above-described conventional speed change operation device, when the shift operation is attempted in a state where the select operation is incomplete, the ball is removed from the groove and prevents the select lever from rotating, so that the subsequent shift operation is continued. There was a problem that would be impossible. That is, the conventional speed change operation device can restrict the shift operation in a state where the select operation is incomplete by the ball being removed from the groove and preventing the rotation, but the shift operation is performed thereafter. This requires a separate operation to return the dislodged ball to the groove.
本発明は、このような事情に鑑みてなされたもので、不完全な状態でのシフト操作又はセレクト操作を規制することができるとともに、その規制後のシフト操作又はセレクト操作を円滑に行わせることができる変速操作装置を提供することにある。
The present invention has been made in view of such circumstances, and can control a shift operation or a select operation in an incomplete state and smoothly perform a shift operation or a select operation after the control. An object of the present invention is to provide a speed change operation device capable of

The speed change operation device according to the first embodiment is arranged in a vehicle transmission such as a manual transmission and other dual clutch transmissions (DCT), and a specific shift among a plurality of shift forks included in the transmission. This is for shifting to a predetermined gear position by a selection operation for selecting a fork and a shift operation for operating a selected specific shift fork.
かかる変速操作装置が適用されるトランスミッションは、図1に示すように、エンジン側と連結されたメインシャフトSa及び駆動輪側と連結されたカウンタシャフトSbが互いに略平行な状態で回転可能に配設されており、当該メインシャフトSaには、1速用ドライブギヤG1a、2速用ドライブギヤG2a、3速用ドライブギヤG3a、4速用ドライブギヤG4a、5速用ドライブギヤG5a、6速用ドライブギヤG6aがそれぞれ取り付けられるとともに、当該カウンタシャフトSbには、1速用ドリブンギヤG1b、2速用ドリブンギヤG2b、3速用ドリブンギヤG3b、4速用ドリブンギヤG4b、5速用ドリブンギヤG5b、6速用ドリブンギヤG6bがそれぞれ取り付けられている。
As shown in FIG. 1, a transmission to which such a speed change operation device is applied is disposed so that a main shaft Sa connected to the engine side and a counter shaft Sb connected to the drive wheel side can rotate in a substantially parallel state. The main shaft Sa includes a first speed drive gear G1a, a second speed drive gear G2a, a third speed drive gear G3a, a fourth speed drive gear G4a, a fifth speed drive gear G5a, and a sixth speed drive. Each gear G6a is attached to the counter shaft Sb, and the first-speed driven gear G1b, the second-speed driven gear G2b, the third-speed driven gear G3b, the fourth-speed driven gear G4b, the fifth-speed driven gear G5b, and the sixth-speed driven gear G6b.

また、1速用ドリブンギヤG1bと2速用ドリブンギヤG2bとの間、3速用ドライブギヤG3aと4速用ドライブギヤG4aとの間、5速用ドライブギヤG5aと6速用ドライブギヤG6aとの間には、それぞれ同期機構H1~H3が設けられている。例えば、1速用ドリブンギヤG1bと2速用ドリブンギヤG2bとの間に設けられた同期機構H1には、スリーブS1及びS2が配設されており、スリーブS1を図1中右側に移動させると、1速用ドリブンギヤG1bがカウンタシャフトSbと一体的に結合して変速段を1速とする一方、スリーブS2を同図中左側に移動させると、2速用ドリブンギヤG2bがカウンタシャフトSbと一体的に結合して変速段を2速とするよう構成されている。
Also, between the first speed driven gear G1b and the second speed driven gear G2b, between the third speed drive gear G3a and the fourth speed drive gear G4a, between the fifth speed drive gear G5a and the sixth speed drive gear G6a. Are provided with synchronization mechanisms H1 to H3, respectively. For example, the synchronizing mechanism H1 provided between the first-speed driven gear G1b and the second-speed driven gear G2b is provided with sleeves S1 and S2. When the sleeve S1 is moved to the right in FIG. When the speed driven gear G1b is integrally coupled with the counter shaft Sb to set the shift speed to the first speed, the second speed driven gear G2b is integrally coupled with the counter shaft Sb when the sleeve S2 is moved to the left side in FIG. Thus, the gear position is set to the second speed.
さらに、カウンタシャフトSbの所定位置には、ドライブギヤGaが形成されており、かかるドライブギヤGaにドリブンギヤGbが噛み合って配設されている。このドリブンギヤGbには、差動機構Dを介して駆動輪に連結されるドライブシャフト(不図示)が取り付けられており、メインシャフトSaから入力されたエンジンの駆動力が、所定の変速段のドライブギヤ(G1a~G6a)及びドリブンギヤ(G1b~G6b)を経た後、カウンタシャフトSb、ドライブギヤGa及びドリブンギヤGb、並びにドライブシャフトを介して駆動輪に伝達されるようになっている。
Furthermore, a drive gear Ga is formed at a predetermined position of the countershaft Sb, and the driven gear Gb is disposed in mesh with the drive gear Ga. A drive shaft (not shown) connected to the drive wheels via the differential mechanism D is attached to the driven gear Gb, and the driving force of the engine input from the main shaft Sa is used to drive a predetermined gear. After passing through the gears (G1a to G6a) and the driven gears (G1b to G6b), they are transmitted to the drive wheels via the counter shaft Sb, the drive gear Ga and the driven gear Gb, and the drive shaft.
一方、同期機構H2、H3には、上記の同期機構H1と同様のスリーブが配設されているとともに、各同期機構H1~H3における一対のスリーブの間には、シフトフォーク(f1、f2、f3)がそれぞれ嵌め込まれている。これらシフトフォーク(f1、f2、f3)は、シフトピースシャフト(h1~h3)を介してシフトピース(fa~fd)とそれぞれ連結されており、変速操作装置1によってシフトフォーク(f1、f2、f3)の何れかを選択的に作動させることにより、任意の変速段への変速を行わせ得るようになっている。
On the other hand, the synchronization mechanisms H2 and H3 are provided with the same sleeve as the above-described synchronization mechanism H1, and a shift fork (f1, f2, f3) is interposed between a pair of sleeves in each of the synchronization mechanisms H1 to H3. ) Is inserted. These shift forks (f1, f2, f3) are connected to the shift pieces (fa to fd) via shift piece shafts (h1 to h3), respectively, and the shift fork (f1, f2, f3) is connected by the shift operation device 1. ) Can be selectively operated to shift gears to an arbitrary gear position.
すなわち、変速操作装置1によって、特定のシフトピース(fa~fd)が選択されるとともに、選択された特定のシフトピース(fa~fd)を所定方向に作動することにより、そのシフトピース(fa~fd)と連結したシフトフォーク(f1、f2、f3)を所定方向に作動させることで、所定の変速段への変速が可能とされているのである。なお、本実施形態においては、シフトピースfaが同期機構H1、シフトピースfbが同期機構H2、及びシフトピースfcが同期機構H3を作動させ得るものとされており、シフトピースfdは、車両を後退させる後進速(リバース)とするものである。
That is, the shift operating device 1 selects a specific shift piece (fa to fd), and operates the selected specific shift piece (fa to fd) in a predetermined direction, whereby the shift piece (fa to fd) is selected. By operating the shift forks (f1, f2, f3) connected to fd) in a predetermined direction, shifting to a predetermined shift stage is possible. In this embodiment, the shift piece fa can operate the synchronization mechanism H1, the shift piece fb can operate the synchronization mechanism H2, and the shift piece fc can operate the synchronization mechanism H3. The shift piece fd moves the vehicle backward. The reverse speed is set to reverse.
ここで、本実施形態に係る変速操作装置1は、上記の如きトランスミッション内に配設されて所定の変速段への変速を行わせるもので、図2に示すように、モータMの駆動により回転可能なシャフト部材2と、アクチュエータAの駆動により移動可能なシフト部材3と、案内溝4と、案内部材6と、規制手段7と、作動部材9と、係合手段10とを有して構成されている。このうち、シャフト部材2は、モータMの出力軸と連結され、当該モータMの駆動により軸周りに回転可能とされている。なお、モータM及びアクチュエータAは、ブラケットB1にて所定位置に固定されている。
Here, the speed change operating device 1 according to the present embodiment is arranged in the transmission as described above to shift to a predetermined speed, and is rotated by driving of a motor M as shown in FIG. A movable shaft member 2, a shift member 3 that can be moved by driving the actuator A, a guide groove 4, a guide member 6, a regulating means 7, an actuating member 9, and an engaging means 10. Has been. Among these, the shaft member 2 is connected to the output shaft of the motor M, and can be rotated around the shaft by driving the motor M. The motor M and the actuator A are fixed at predetermined positions by a bracket B1.
シフト部材3は、シャフト部材2に取り付けられた略円筒状部材から成り、当該シャフト部材2に対する長手方向の摺動及び当該シャフト部材2との一体的な回転とが選択的に行われることにより、セレクト操作又はシフト操作が行われるものであって、本実施形態においては、当該シャフト部材2の長手方向(図2中上下方向)に沿って摺動してセレクト操作を行い得るとともに、当該シャフト部材2と一体的に回転してシフト操作を行い得るものである。本実施形態に係るシフト部材3は、シリンダ等から成るアクチュエータAによりセレクト操作が可能とされるとともに、モータMによりシフト操作がなされるようになっている。
The shift member 3 is composed of a substantially cylindrical member attached to the shaft member 2, and the sliding in the longitudinal direction with respect to the shaft member 2 and the integral rotation with the shaft member 2 are selectively performed. A select operation or a shift operation is performed. In this embodiment, the select operation can be performed by sliding along the longitudinal direction (vertical direction in FIG. 2) of the shaft member 2 and the shaft member. 2 can rotate together with the shift operation. The shift member 3 according to this embodiment can be selected by an actuator A composed of a cylinder or the like, and can be shifted by a motor M.
より具体的には、シフト部材3の外周面には、一対の凸状部から成る係止部3bが形成されており、当該係止部3bの間には、図9に示すように、フォーク状の作動部材9が取り付けられている。かかる作動部材9は、当該シフト部材3をシャフト部材2に対して摺動(停止したシャフト部材2に対してシフト部材3が相対的に摺動)させてセレクト操作するとともに、当該シフト部材3の回転(シャフト部材2と一体的な回転)を許容し得るもので、アクチュエータAの作動部Aaに取り付けられている。
More specifically, a locking portion 3b composed of a pair of convex portions is formed on the outer peripheral surface of the shift member 3, and a fork is provided between the locking portions 3b as shown in FIG. A shaped actuating member 9 is attached. The actuating member 9 performs a selection operation by sliding the shift member 3 with respect to the shaft member 2 (the shift member 3 slides relative to the stopped shaft member 2). Rotation (rotation integral with the shaft member 2) can be allowed, and is attached to the operating portion Aa of the actuator A.
これにより、作動部材9は、シフト部材3の上下方向に対して係合した状態とされるとともに、当該シフト部材3の周方向に対して非係合な状態(シフト部材3の回転方向の動作を許容した状態)とされており、アクチュエータAを駆動して作動部Aaを図2中上下方向に動作させると、作動部材9を介してシフト部材3を同方向に摺動させ得るよう構成されている。
Accordingly, the operating member 9 is engaged with the shift member 3 in the vertical direction, and is not engaged with the circumferential direction of the shift member 3 (operation in the rotation direction of the shift member 3). In this state, when the actuator A is driven to move the operating portion Aa in the vertical direction in FIG. 2, the shift member 3 can be slid in the same direction via the operating member 9. ing.
一方、シフト部材3の外周面(作動部材9が取り付けられた部位より上部)には、係合手段10が取り付けられている。かかる係合手段10は、例えば金属製の球状部材から成る係合ボール10aと、該係合ボール10aを嵌合させ得るとともにシフト部材3の摺動方向(セレクト操作方向)に延びた長溝から成る係合溝10bとから主に構成されており、セレクト操作時にシフト部材3のシャフト部材2に対する摺動を許容するとともに、シフト操作時にシフト部材3とシャフト部材2とを係合して当該シフト部材3をシャフト部材2と一体的に回転させ得るようになっている。
On the other hand, the engaging means 10 is attached to the outer peripheral surface of the shift member 3 (above the part where the operating member 9 is attached). The engaging means 10 includes an engaging ball 10a made of, for example, a metal spherical member, and a long groove that can fit the engaging ball 10a and extends in the sliding direction of the shift member 3 (select operation direction). The shift groove 3 is mainly composed of an engagement groove 10b, and allows the shift member 3 to slide relative to the shaft member 2 during a select operation, and engages the shift member 3 and the shaft member 2 during the shift operation. 3 can be rotated integrally with the shaft member 2.
すなわち、セレクト操作時においてアクチュエータAを駆動させて作動部材9を動作させると、係合ボール10aと係合溝10bとの係合がなされず、シフト部材3がシャフト部材2の長手方向に対して摺動可能とされるとともに、シフト操作時においてモータMを駆動させると、係合ボール10aと係合溝10bとが係合して、シフト部材3とシャフト部材2とが一体的に回転するのである。なお、図中符号10cは、係合ボール10aが係合溝10bから脱落する方向(シフト部材3の径方向)に移動するのを防止する固定ボルトを示しており、当該固定ボルト10cの突端10caが係合ボール10aに当接した状態で固定されている。
That is, when the actuator 9 is driven to operate the operating member 9 during the selection operation, the engagement ball 10a and the engagement groove 10b are not engaged, and the shift member 3 is moved in the longitudinal direction of the shaft member 2. When the motor M is driven during the shifting operation, the engaging ball 10a and the engaging groove 10b are engaged, and the shift member 3 and the shaft member 2 rotate integrally. is there. In addition, the code | symbol 10c in the figure has shown the fixed volt | bolt which prevents that the engagement ball | bowl 10a moves to the direction (diameter direction of the shift member 3) which drops out from the engagement groove | channel 10b, and the protrusion 10ca of the said fixed volt | bolt 10c. Is fixed in contact with the engagement ball 10a.
さらに、シフト部材3の所定位置には、作動部3aが一体的に形成されており、シフト部材3がシャフト部材2の長手方向に沿って摺動することにより、作動部3aと嵌合するシフトピース(fa~fd)が選択される(図11参照)とともに、シフト部材3がシャフト部材2と一体的に回転するのに伴って作動部3aが所定方向に回転することにより、選択されたシフトピース(fa~fd)を同方向に作動させ(図12、13参照)、そのシフトピース(fa~fd)に対応したシフトフォーク(f1、f2、f3)を作動させ得るよう構成されている。
Further, an operating portion 3a is integrally formed at a predetermined position of the shift member 3, and the shift member 3 is slid along the longitudinal direction of the shaft member 2 to be fitted with the operating portion 3a. The pieces (fa to fd) are selected (see FIG. 11), and when the shift member 3 rotates integrally with the shaft member 2, the operating portion 3a rotates in a predetermined direction, thereby selecting the selected shift. The pieces (fa to fd) are operated in the same direction (see FIGS. 12 and 13), and the shift forks (f1, f2, and f3) corresponding to the shift pieces (fa to fd) can be operated.
案内溝4は、シフト部材3の外周面に形成され、図3に示すように、当該シフト部材3のセレクト操作時の摺動方向(セレクト操作方向α)及びシフト操作時の回転方向(シフト操作方向β)に対応して形成された溝形状から成るもので、同図中上下方向に延びたセレクト溝4aと、同図中左右方向に延びたシフト溝4bと、案内部材6の寸法及び形状に対応(本実施形態においては円形状)して形成されたポジション保持溝4cとから主に構成されている。
The guide groove 4 is formed on the outer peripheral surface of the shift member 3, and as shown in FIG. 3, the sliding direction (select operation direction α) when the shift member 3 is selected and the rotation direction (shift operation) when the shift operation is performed. The shape and the shape of the guide member 6 is composed of a groove shape formed corresponding to the direction β), the select groove 4a extending in the vertical direction in the figure, the shift groove 4b extending in the horizontal direction in the figure. And a position holding groove 4c formed corresponding to (circular shape in the present embodiment).
セレクト溝4aは、セレクト操作方向αに延びて形成され、当該セレクト操作時に案内部材6が案内される部位(ニュートラル位置に相当する部位)から成り、シフト溝4bは、当該セレクト溝4aの所定位置から分岐してシフト操作方向βに延びて形成され、当該シフト操作の過程で案内部材6が案内される部位から成る。また、ポジション保持溝4cは、シフト溝4bの先端部に形成され、シフト操作の完了時に案内部材6が位置する部位から成る。
The select groove 4a is formed to extend in the select operation direction α and includes a portion (a portion corresponding to the neutral position) where the guide member 6 is guided during the select operation. The shift groove 4b is a predetermined position of the select groove 4a. And is formed to extend in the shift operation direction β and to which the guide member 6 is guided in the process of the shift operation. Further, the position holding groove 4c is formed at the tip end portion of the shift groove 4b and includes a portion where the guide member 6 is positioned when the shift operation is completed.
案内部材6は、図2に示すように、案内溝4に対してコイルバネ5(付勢手段)により付勢されつつ嵌合して取り付けられたもので、本実施形態においては、金属製の球状部材から成る。かかる案内部材6及びコイルバネ5は、シフト部材3の近傍に固定された筒状の保持部材8内に保持されている。また、本実施形態に係る保持部材8は、ブラケットB1から延設されたブラケットB2に固定されている。
As shown in FIG. 2, the guide member 6 is fitted and attached to the guide groove 4 while being urged by a coil spring 5 (biasing means). It consists of members. The guide member 6 and the coil spring 5 are held in a cylindrical holding member 8 fixed in the vicinity of the shift member 3. Further, the holding member 8 according to this embodiment is fixed to a bracket B2 extending from the bracket B1.
なお、本実施形態においては、案内部材6がコイルバネ5により案内溝4に対して付勢されているが、他の付勢手段(他の形態のバネや弾性部材等、汎用的な付勢手段)にて付勢されたものとしてもよい。また、本実施形態に係る案内部材6は、球状部材から成るものとされているが、案内溝4に対して付勢手段により付勢されつつ嵌合して取り付けられたものであれば足り、例えばローラ状部材若しくはピン状部材から成るものとしてもよい。
In this embodiment, the guide member 6 is urged against the guide groove 4 by the coil spring 5, but other urging means (general-purpose urging means such as other forms of springs and elastic members). ). Further, the guide member 6 according to the present embodiment is made of a spherical member, but it is sufficient if it is fitted and attached to the guide groove 4 while being urged by the urging means, For example, it may be a roller-shaped member or a pin-shaped member.
しかして、案内部材6は、ニュートラル状態のとき、セレクト溝4aに位置するとともに、ニュートラル状態から任意の変速段に操作されてシフト部材3が摺動(セレクト操作による動作)及び回転(シフト操作による動作)すると、セレクト溝4aから分岐する任意のシフト溝4bに案内されるとともに、変速操作が完了した時点で、当該シフト溝4bの先端部に位置するポジション保持溝4cに嵌合した状態とされる。
When the guide member 6 is in the neutral state, the guide member 6 is positioned in the select groove 4a, and the shift member 3 is slid (operated by the select operation) and rotated (operation by the shift operation) from the neutral state to an arbitrary gear position. Operation), it is guided to an arbitrary shift groove 4b branched from the select groove 4a, and when the speed change operation is completed, it is in a state of being fitted to the position holding groove 4c located at the tip of the shift groove 4b. The
ここで、本実施形態に係る保持部材8には、案内部材6及びコイルバネ5(付勢手段)に加え、規制手段7が保持されている。この規制手段7は、案内溝4から外れてコイルバネ5(付勢手段)による付勢力に抗して図2中符号a方向に移動しようとする案内部材6と当接して当該移動を規制することにより、当該案内溝4から案内部材6が外れる方向へのシフト部材3の移動を規制し得るものである。
Here, in addition to the guide member 6 and the coil spring 5 (biasing means), the restricting means 7 is held in the holding member 8 according to the present embodiment. This restricting means 7 comes out of contact with the guide groove 4 and abuts against the guide member 6 that moves in the direction a in FIG. 2 against the urging force of the coil spring 5 (biasing means) to restrict the movement. Thus, the movement of the shift member 3 in the direction in which the guide member 6 is detached from the guide groove 4 can be restricted.
具体的には、規制手段7は、保持部材8内に形成された金属製の棒状部材から成り、その先端面から所定寸法離間した位置に案内部材6が保持されるよう構成されており、シフト操作過程において、当該案内部材6が案内溝4から外れてコイルバネ5(付勢手段)による付勢力に抗して移動(図2中符号a方向へ移動)しようとすると、その案内部材6が規制手段7の先端面に当接して、それ以上の移動を規制し得るのである。
Specifically, the restricting means 7 is made of a metal rod-like member formed in the holding member 8, and is configured so that the guide member 6 is held at a position spaced by a predetermined dimension from the tip surface thereof. In the operation process, if the guide member 6 is disengaged from the guide groove 4 and attempts to move against the urging force of the coil spring 5 (biasing means) (moves in the direction a in FIG. 2), the guide member 6 is restricted. It can abut against the tip surface of the means 7 to restrict further movement.
しかるに、案内部材6がセレクト溝4aにおけるシフト溝4bとの分岐部に位置するとき、図4に示すように、セレクト溝4aの縁部とシフト溝4bの縁部との間の4つの交叉点P1と接触した状態とされており、当該案内部材6がポジション保持溝4cに達すると、図5に示すように、当該ポジション保持溝4cの輪郭縁4caに沿って接触した状態とされる。これにより、シフト操作後においては、案内部材6がポジション保持溝4cに位置し、安定した状態が維持されるようになっている。
However, when the guide member 6 is positioned at a branch portion of the select groove 4a with the shift groove 4b, as shown in FIG. 4, four crossing points between the edge of the select groove 4a and the edge of the shift groove 4b are provided. When the guide member 6 reaches the position holding groove 4c, it is brought into contact with the contour edge 4ca of the position holding groove 4c as shown in FIG. Thus, after the shift operation, the guide member 6 is positioned in the position holding groove 4c, and a stable state is maintained.
また、案内部材6は、シフト溝4aに位置するとき、図6に示すように、当該シフト溝4bの対向する2つの点P2と接触した状態とされるとともに、セレクト溝4aにおけるシフト溝4bとの分岐部以外に位置するとき、図7に示すように、当該シフト溝4aの対向する2つの点P3と接触した状態とされる。そして、対向する一対のP2間の寸法d3(図6参照)及び対向する一対のP3間の寸法d4(図7参照)は、4つのP1のうち交差する一対のP1間の寸法d1(図4参照)及びポジション保持溝4cにおける輪郭縁の直径寸法d2(図5参照)より小さく設定されている。
When the guide member 6 is positioned in the shift groove 4a, as shown in FIG. 6, the guide member 6 is brought into contact with two opposing points P2 of the shift groove 4b, and the shift groove 4b in the select groove 4a When it is located at a position other than the branched portion, as shown in FIG. 7, it is in a state of being in contact with two opposing points P3 of the shift groove 4a. A dimension d3 (see FIG. 6) between a pair of opposing P2 and a dimension d4 (see FIG. 7) between a pair of opposing P3 are a dimension d1 (see FIG. 4) between a pair of intersecting P1 out of four P1. And a diameter dimension d2 of the contour edge in the position holding groove 4c (see FIG. 5).
上記構成により、図8に示すように、案内部材6は、シフト溝4aに位置するとき(図6参照)及びセレクト溝4bにおけるシフト溝4aとの分岐部以外に位置するとき(図7参照)、案内溝4における他の部位(セレクト溝4aにおけるシフト溝4bとの分岐部及びポジション保持溝4c)に位置するときよりも規制手段7に近接(規制手段7の先端面に接近した位置)するよう設定されている。
With the above configuration, as shown in FIG. 8, when the guide member 6 is located in the shift groove 4a (see FIG. 6) and when it is located in a portion other than the branching portion of the select groove 4b with the shift groove 4a (see FIG. 7). , Closer to the restricting means 7 (position closer to the front end surface of the restricting means 7) than when located in other parts of the guide groove 4 (the branching portion of the select groove 4a with the shift groove 4b and the position holding groove 4c). It is set as follows.
すなわち、図8に示すように、案内部材6がセレクト溝4aにおけるシフト溝4bとの分岐部に位置するときの当該案内部材6と規制手段7との間の離間寸法をT1、案内部材6がポジション保持溝4cに位置するときの当該案内部材6と規制手段7との間の離間寸法をT2とし、案内部材6がセレクト溝4aにおけるシフト溝4bとの分岐部以外に位置するとき及びシフト溝4aに位置するときの当該案内部材6と規制手段7との間の離間寸法をT3とすると、T3<T2<T1の大小関係に設定されており、寸法T3が最も小さく設定されているのである。
That is, as shown in FIG. 8, when the guide member 6 is located at a branch portion of the select groove 4a with the shift groove 4b, the separation dimension between the guide member 6 and the restricting means 7 is T1, and the guide member 6 is When the distance between the guide member 6 and the restricting means 7 when positioned in the position holding groove 4c is T2, the guide member 6 is positioned at a position other than the branching portion of the select groove 4a with the shift groove 4b and the shift groove. Assuming that the distance between the guide member 6 and the restricting means 7 when positioned at 4a is T3, the size relationship T3 <T2 <T1 is set, and the size T3 is set to be the smallest. .
特に、本実施形態に係る案内部材6は、球状部材から成るとともに、シフト部材3のセレクト操作又はシフト操作に応じて案内溝4にて案内される案内状態と、案内溝4を乗り上げて外れようとする乗り上げ状態となり得るものとされ、案内状態の案内部材6の上端位置と乗り上げ状態の案内部材6の上端位置との間に規制手段7における案内部材6との当接部位(突端面)が位置するよう構成されている。
In particular, the guide member 6 according to the present embodiment is formed of a spherical member, and is guided by the guide groove 4 according to the selection operation or the shift operation of the shift member 3, and rides on the guide groove 4 to come off. The contact portion (protruding end surface) of the restricting means 7 with the guide member 6 is between the upper end position of the guide member 6 in the guide state and the upper end position of the guide member 6 in the ride state. Configured to be located.
これにより、案内部材6が球状部材から成るので、コストを抑えることができるとともに、摺動抵抗が低減されるので、シフト部材3を円滑に作動させることができる。さらに、案内状態の案内部材6の上端位置と乗り上げ状態の案内部材6の上端位置との間に規制手段7における案内部材6との当接部位が位置するので、案内部材6が案内溝4にて案内される過程において当該案内部材6と規制手段7との間にクリアランスが生じ、シフト部材3の作動を円滑に行わせることができるとともに、案内部材6が案内溝4を乗り上げようとした際、規制手段7に対して確実に当接させ、当該案内溝4から外れてしまうのを確実に防止することができる。
Thereby, since the guide member 6 is formed of a spherical member, the cost can be suppressed and the sliding resistance can be reduced, so that the shift member 3 can be operated smoothly. Furthermore, since the contact portion of the restricting means 7 with the guide member 6 is located between the upper end position of the guide member 6 in the guide state and the upper end position of the guide member 6 in the riding state, the guide member 6 is placed in the guide groove 4. In the process of being guided, a clearance is generated between the guide member 6 and the restricting means 7 so that the shift member 3 can be operated smoothly and the guide member 6 tries to ride over the guide groove 4. Thus, it can be surely brought into contact with the restricting means 7 and reliably prevented from coming off from the guide groove 4.
