The gigback 7 for making block selecting bar 1 be back to neutral gear position P2 (N) is provided with manual transmission T.According to reality The gigback 7 for applying mode is arranged on the bottom side surface (i.e. the inner side of housing 5) for the base portion 61 for supporting outer bar 31 and detent mechanism 6 Place, as shown in Fig. 5 A, Fig. 5 B, Fig. 5 C and Fig. 5 D.Gigback 7 includes being connected to the cylindrical member 71 of axle 32, and axle 32 is can revolve The mode turned supports outer bar 31.Cylindrical member 71 is connected to the other end side of axle 32 and cylindrical member 7 in end side Open wide.Cylindrical member 71 is integrally attached to axle 32 so that the axis direction of cartridge is consistent with the longitudinal direction of outer bar 31. Therefore, outer bar 31 and cartridge 71 are restricted on rotating against for axle 32.Ball 72 is supported in the spacious of cylindrical member 71 Open at side and can rotate about the axis and can move in the axial direction.Ball 72 passes through the spring that is contained in cylindrical member 71 73 are put by the open end lateral deviation towards cylindrical member 71.
Ball 72 is in contact with forming the cam 74 on base portion 61.Cam is formed by raised portion (countersink), and Therefore, moved by spring 73 and the ball 72 biased by the bias force of spring 73 by the minimum point (peak) towards cam 74 It is dynamic.Therefore, i.e., it is integrally attached to keep the outer bar 31 of the cylindrical member 71 of ball 72 via axle 32 all the time by towards cam 74 Minimum point (peak) direction biases.
It is to be noted here that the minimum point (peak) of cam 74 corresponds to the neutral gear position P2 (N) of block selecting bar 1, and Therefore, outer bar 31 is biased towards neutral displaced position corresponding with the neutral gear position P2 (N) of block selecting bar 1.Thus, due to outer bar 31 are biased towards neutral displaced position all the time, and the block selecting bar 1 of outer bar 31 is connected to all the time by towards neutral via block selecting drag-line 3 Position P2 (N) is biased.In other words, block selecting bar 1 and outer bar 3 are interlocked by block selecting drag-line 3, and elected pin 1 returns to sky When gear puts P2 (N), outer bar 31 also returns to neutral displaced position by rotation.
Next, the operation to the detent mechanism 6 with structure disclosed above illustrates.First, to by fixed Outer bar 31 to the positioning action of predetermined adjustment position that position mechanism 6 is carried out illustrates.
According to embodiment, the regulation operating position of block selecting bar 1 corresponds to " low gear " operating position P1, " low gear " operative position Put P1 and be positioned to adjacent with the block selecting operating position P4 that reverses gear on block selecting bar neutral gear position P2 (N) direction, as shown in Figure 2.Change sentence Talk about, when select pin 1 block selecting operate at door 2 along block selecting operation direction Se perform to reverse gear block selecting operating position P4 when, it is " low Gear " operating position P1 is by the ring pull mechanism limitation for the operating mechanism that reverses gear.In other words, " low gear " operating position P1 block selecting behaviour Make position to be determined by vehicle side.
On the other hand, as shown in Figure 5A, the rotation position A2 (N) of cylindrical member 71 is by stopping at the minimum point of cam 74 (peak) place and mechanically determined.The outer bar 31 that cylindrical member 71 is connected to by axle 32 stops at rotation position A2 (N) Place, and therefore, the block selecting bar 1 connected by block selecting drag-line 3 stops at block selecting bar neutral gear position P2 (N) place.Therefore, block selecting bar 1 block selecting bar neutral gear position P2 (N) is determined at the side of outer bar 31 (so-called transmission side).It is to be noted here that connected by axle 32 Rotation position A2 (N) when the outer bar 31 connect stops corresponds to the neutral displaced position of outer bar 31.Thus, in the description below, Neutral displaced position will be referred to as neutral displaced position A2 (N).
As pointed out in Fig. 5 B, the rotation position A3 of cylindrical member 71 can pass through the contact with base portion 61 of cylindrical member 71 And mechanically determined.Therefore, the outer bar 31 being integrally connected with axle 32 is stopped at the A3 of rotation position, and therefore, is passed through The block selecting bar 1 that block selecting drag-line 3 connects also is stopped at " high gear " operating position P3.In other words, " high gear " operating position P3 by The side of outer bar 31 (so-called transmission side) determines.The bias force of spring 73 and cam effect (the cam reaction as caused by cam 74 Power) it is generated to cylindrical member 71 being offset so that the direction indicated by the arrow that ball 72 shows along in as Fig. 5 B is moved.
In addition, as shown in Figure 5 C, the rotation position A4 of cylindrical member 71 can connecing by cylindrical member 71 and base portion 61 Touch and mechanically determined.Therefore, the outer bar 31 being integrally connected with axle 32 is stopped at the A4 of rotation position, and therefore, is led to The block selecting bar 1 for crossing the connection of block selecting drag-line 3 is also stopped at the block selecting operating position P4 that reverses gear.In other words, reverse gear block selecting operative position P4 is put also to be determined by the side of outer bar 31 (so-called transmission side).The bias force of spring 73 and the cam effect as caused by cam 74 are (convex Wheel reaction force) it is generated to for cylindrical member 71 to be offset so that the direction indicated by the arrow that ball 72 shows along in as Fig. 5 C It is mobile.
However, as shown in Figure 5 D, at the rotation position A1 of cylindrical member 71, ball 72 not yet reaches the minimum point of cam 74 (peak), and in addition, cylindrical member 71 does not contact with base portion 61.Therefore, the rotation position A1 of cylindrical member 71 is not solid Fixed, but in the mobile shape of minimum point (peak) direction of the cam 74 shown in arrow of the ball 72 along in by Fig. 5 D movement State.Thus, rotation position A1 is not determined mechanically.Therefore, the outer bar 31 being integrally connected with axle 32 passes through gigback 7 Bias force be also at along neutral displaced position A2 (N) direction move mobile status and rotation position A1 will not be stopped at Place.Therefore, the block selecting bar 1 connected by block selecting drag-line 3 will not stop at " low gear " operating position corresponding to rotation position A1 At P1, and " low gear " operating position A1 can not mechanically be determined by the side of outer bar 31 (so-called transmission side).
Therefore, detent mechanism 6 determines the rotation of outer bar 31 corresponding with " low gear " the operating position P1 determined by vehicle side Position A1.The block selecting that operator will be in the state of block selecting bar 1 is selected as " low gear " operating position P1 by block selecting drag-line 3 Bar 1 is connected with the outer bar 31 positioned by detent mechanism 6 to rotation position A1, and adjust the length (tension force) of block selecting drag-line 3 with The rotation position A1 of outer bar 31 is set to be accurately matched with " low gear " the operating position P1 of block selecting bar 1.Therefore, it is selected to be elected to pin 1 When being selected as " low gear " operating position P1, outer bar 31 is interlocked accurately to be rotated to rotation position A1 with block selecting bar 1, so as to grasp Make power and be accurately delivered to block selecting axle 52 thus to perform accurate block selecting operation.
Therefore, predetermined adjustment position is set to rotation position A1 according to the detent mechanism 6 of embodiment.Thus, pin 63 Position (positioning) place that rotation position A1 is kept in outer bar 31 moves in the axial direction.Pay attention to, according to embodiment, pin 63 The rotation position A1 than outer bar 31 on neutral displaced position A2 (N) direction more adjacent to neutral displaced position A2 (N) position Place's movement.
When the length of block selecting drag-line 3 is conditioned, pin 63 overcomes the bias force of spring 64 to extend to bonding station, such as Fig. 6 A Shown in Fig. 6 B.Thus, as shown in Figure 6B, have been extended to the pin 63 of bonding station engages with the bonding part 31a of outer bar 31, Outer bar 31 is biased together with snap ring 65 along neutral displaced position A2 (N) direction.Thus, as shown in Figure 6A, the position of outer bar 31 It is determined to rotation position A1 and stops at the A1 of the position.In this state, outer bar 31 is returned mechanism 7 and passes through biasing Power (so-called stopping power) is along as the direction biasing indicated by the arrow in Fig. 6 A.
In this state, because pin 63 passes through accommodating position of the spring 64 by direction as indicated by the arrow U in Fig. 6 B Biasing, it is fixed to and slightly holds part 63b snap ring 65 also to house location bias by direction.Pass through the bias force, the contact of snap ring 65 Surface is strongly shifted onto in the bonding part 31a peripheral edge surface of outer bar 31.Therefore, the contact surface of snap ring 65 and outer bar 31 Between produce frictional force and the frictional force and prevent snap ring 65 from being shifted relative to outer bar 31, and therefore can anti-shotpin 63 with it is outer Unexpected disengagement between bar 31.Outer bar 31 can continue to be positioned optimally at the A1 of rotation position.
In the engaged condition, the outer surface of pin 63 is in contact with the bonding part 31a of outer bar 31, and due to passing through all the time Gigback 7 applies to the bias force of outer bar 31 and causes do not have any gap between pin 63 and outer bar 31.Further, since pin 63 are supported without run-off the straight by the inner peripheral surface of bossing 62, therefore pin 63 can accurately stretch out in the axial direction. Thus, as described, outer bar 31 extremely accurately can be positioned at the A1 of rotation position by detent mechanism 6.
In the engaged condition, the length (tension force) of block selecting drag-line 3 is adjusted to suitable length (tension force) by operator.Cause And select to pass through the quilt of block selecting drag-line 3 to " low gear " operating position P1 block selecting bar 1 and outer bar 31 of the rotation in rotation position A1 Extremely accurately interlock.After operation is adjusted to the length of block selecting drag-line 3, operator operate ring pull mechanism while Execution reverse gear block selecting operation.In other words, operator grasps block selecting bar 1 from the most predetermined block selecting of " low gear " operating position P1 gearshifts Make the block selecting operating position P4 that reverses gear of position.Pay attention to, the gearshift of block selecting operation leaves neutral along the block selecting operating position P4 that reverses gear Position P2 (N) direction performs.
When operator, which shifts to block selecting bar 1, reverses gear block selecting operating position P4, as shown in Figure 7 A, outer bar 31 along towards with The reverse gear direction of rotation position A4 corresponding to block selecting operating position A4 rotates along the direction for leaving neutral displaced position A2 (N). In other words, (it corresponds to the block selecting of block selecting bar 1 and operates direction in the direction indicated by arrow Se of the outer bar 31 along in as Fig. 7 A Se) rotate.In this state, in being located at due to rotation position A1 between rotation position A4 and neutral displaced position A2 (N) Between position, therefore outer bar 31 is rotated by overcoming the bias force applied by return component 7 along rotation position A4 directions.
When outer bar 31 rotates along rotation position A4 directions, as shown in Figure 7 B, pin 63 and snap ring 65 and bonding part 31a it Between engagement be released.When engagement is released, pin 63 and snap ring 65 are moved to accommodating position from bonding station.Thus, pin 63 It is placed in bossing 62.In the state of pin 63 has moved to accommodating position, pin 63 and snap ring 65 and outer bar 31 are not Contact.Therefore, outer bar 31 completely freely rotates around axle 32.
In the case where block selecting bar 1 has shifted to the block selecting operating position P4 that reverses gear, if operator by hand from block selecting bar 1 Release, as shown in figure 8, then outer bar 31 rotates around axle 32 along neutral displaced position A2 (N) direction (Return-ing direction).With outer bar 31 To neutral displaced position A2 (N) rotation interlocking in the case of, block selecting bar 1 returns to neutral gear position P2 (N).Pass through block selecting bar 1 To neutral gear position P2 (N) this return, it can confirm that pin 63 must be moved to accommodating position and adjust the length of block selecting drag-line 3 The regulation operation for spending (tension force) is completed.
As by described above will be understood that, manual transmission T, hand gear are applied to according to the present apparatus of embodiment Case T includes：Block selecting bar 1, block selecting bar 1 are operated by the operator of vehicle in variable speed operation and operated with carrying out block selecting；Door 2, door 2 will The operating position that the block selecting carried out by block selecting bar 1 operates guides the operating position to four or more than four；Housing 5, housing 5 In be equipped with transmission mechanism 51；Block selecting axle 52, block selecting axle 52 are contained in housing 5 and operated in response to the block selecting of block selecting bar 1 To operate transmission mechanism 51 so that it performs variable speed operation；Outer bar 31, outer bar 31 are arranged on the outside of housing 5 and are connected to choosing Gear shaft 52, the outer bar for the drag-line of variable speed operation by being connected to block selecting bar 1 so that the operating physical force for being input to block selecting bar 1 obtains To transmit, and it is passed in a manner of the operating physical force transmitted is rotated by making block selecting axle 52 pass through the operating physical force transmitted To block selecting axle 52；And gigback 7, gigback 7 are used to make block selecting bar 1 be back to along block selecting operation direction Se in door 2 Neutral gear position P2 (N).According to the present apparatus for adjusting drag-line 3, situation of the outer bar 31 in the block selecting operation interlocking with block selecting bar 1 Lower gearshift, and outer bar 31 is in the feelings of the return interlocking of the block selecting bar 1 with being carried out by gigback 7 to neutral gear position P2 (N) The neutral displaced position A2 (N) corresponding to neutral gear position P2 (N) is shifted under condition.Manual transmission is used for speed change to adjust The cable regulating device of the drag-line 3 of operation includes detent mechanism 6, and detent mechanism 6 is used to position outer bar 31 to predetermined adjustment position A1 is put so that the drag-line 3 for variable speed operation to be adjusted, predetermined adjustment position A1 corresponds to the regulation operating position of block selecting bar 1 P1 is adjusted with the block selecting operating position to block selecting bar 1, wherein, the neutral of the regulation operating position and block selecting bar 1 of block selecting bar 1 Position P2 (N) is different.Detent mechanism 6 includes：Bonding part 31a, bonding part 31a are arranged on the outer surface of outer bar 31, are outer Bar 31 is positioned to the opening position during A1 of predetermined adjustment position；Pin 63, pin 63 is in response to its spor ts choice in the axial direction Engaged with bonding part 31a or disengagement；Tubular bossing 62, tubular bossing 62 are formed in the outer surface of housing 5 Upper and accommodating in a movable manner pin 63；Spring 64, spring 64 are arranged between pin 63 and bossing 62 and by pins 63 are biased to pin 63 and the disconnection of bonding part 31a disengagements connects from pin 63 with the bonding part 31a bonding stations engaged Close position；And snap ring 65, snap ring 65 are arranged on slightly holding at the 63b of part and overcoming the bias force of spring 64 will be with connecing for pin 63 The pin 63 for closing part 31a engagements remains to bonding station, and block selecting bar 1 leaves neutral gear position P2 (N) direction along block selecting bar 1 Predetermined block selecting operating position P4 is shifted to, and works as the direction gearshift that outer bar 31 leaves neutral displaced position A2 (N) along outer bar 31 When, pin 63 to bonding part 31a holding are released.
Manual transmission T also includes the operating mechanism 12,13,14 that reverses gear, and the operating mechanism 12,13,14 that reverses gear is on the edge of block selecting bar 1 Block selecting operation direction Se shift to selection reverse speed level reverse gear block selecting operating position P4 when operated.The regulation of block selecting bar 1 Operating position P1 is following block selecting operating positions：The block selecting operating position is the block selecting for being positioned in block selecting bar 1 behaviour at door 2 Make on the Se of direction along the pace level towards the neighbouring block selecting operating position P4 that reverses gear in neutral gear position P2 (N) direction.Predetermined choosing Gear operating position can be set to the block selecting operating position P4 that reverses gear at door 2.
Therefore, when pin 63 and snap ring 65 are with forming the bonding part 31a in outer bar 31 in pin 63 in the axial direction from convex When playing the joint place engagement that part 62 protrudes, outer bar 31 can be positioned at corresponding to predetermined adjustment position by detent mechanism 6 Rotation position A1 at.Therefore, it is " low gear " of the regulation operating position of block selecting bar 1 when manual transmission T is attached to vehicle Operating position P1 and for outer bar 31 predetermined adjustment position rotation position A1 can be unified each other (corresponding) into Unification state.Therefore, under this unification state, operator can will be located into corresponding unification (corresponding) position The block selecting bar 1 at place is connected with outer bar 31 via block selecting drag-line 3.
Further, since the outer bar 31 of block selecting bar 1 is connected to by along towards neutral displaced position A2 (N) by block selecting drag-line 3 Direction biasing, therefore pin 63 and the bonding part 31a of outer bar 31 can be made to be in contact with each other and not produce any gap therebetween. Therefore, in the regulation operation of length (tension force) of block selecting drag-line 3 is adjusted by operator, detent mechanism 6 can be high by outer bar 31 Degree is precisely located to rotation position A1.
In addition, after completing to adjust operation, operator can be by performing block selecting bar 1 to only in the compartment of vehicle Keep off the block selecting operating position P4 block selecting operation easily engagement between release pin 63 and the bonding part 31a of outer bar 31.Therefore, It need not such as slip into the narrow space of under-vehicle and discharge this operation of positioning of outer bar 31, and it is possible thereby to pass through letter Single operation is released through the positioning of the outer bar 31 of the progress of pin 63.Thus, it is possible to greatly improve the regulation operation of operator can Operability.In addition, pin 63 and snap ring 65 do not contact after accommodating position is had been moved to outer bar 31, and therefore, choosing Pin 1 can be operated freely.
In addition, predetermined block selecting operating position can be determined that the block selecting operating position P4 that reverses gear, and therefore, make in regulation After industry is completed, operated by the block selecting of block selecting bar 1 to the block selecting operating position P4 that reverses gear, operator can easily release pin 63 With snap ring 65 and the bonding part 31a of outer bar 31 engagement, so as to greatly improve the operability of regulation operation.Thus, pass through Regulation operating position (" low gear " operating position P1) and predetermined block selecting operating position (reverse gear block selecting operating position P4) is specified, can be with The standardization operated, the type or size of the vehicle installed without regard to manual transmission.
In addition, in order to ensure good block selecting operability, it is preferred that the block selecting operation of block selecting bar 1 in manual transmission T Position is determined in transmission side rather than in vehicle side.However, " low gear " the operating position P1 that block selecting bar 1 be present can not pass through outer bar The Mechanical Contact of 31 sides is come situation about determining.Even if in this case, for example, in manual transmission without the operation machine that reverses gear In the case of structure, if " low gear " operating position P1 can be by the way that outer bar 31 be positioned to corresponding with " low gear " operating position P1 Rotation position A1 and determined by any device of vehicle side, then the length of block selecting drag-line 3 can be according to progress disclosed above Regulation.Thus, the corresponding relation between the rotation position A1 of " low gear " operating position P1 and outer bar 31 can be appropriately determin. After regulation operation is completed, operated by the block selecting of block selecting bar 1 to the block selecting operating position P4 that reverses gear, can be with release pin 63 and card The engagement of ring 65 and the bonding part 31a of outer bar 31.Therefore, in this case, can also greatly improve regulation operation can Operability.
In these cases, the cardinal extremity part 63a of pin 63 external diameter can be set to slightly hold part 63b's more than pin 63 External diameter.
For example, when repairing manual transmission T, gearbox T is dismantled with operation and the repairing of placing under repair from vehicle Reason operation is reinstalled as quickly as possible to vehicle after completing.In such a case it is necessary to readjust the length of block selecting drag-line 3.As institute Illustrate, the pin 63 for being provided with snap ring 65 of detent mechanism 6 is moved to accommodating position after operation is adjusted.In other words, exist After adjusting operation, the pin 63 for being provided with snap ring 65 is not removed from manual transmission but is placed in bossing 62. Therefore, detent mechanism 6 can be reused for the regulation operation of guy cable length when manual transmission T reinstalls to vehicle.
Although pin 63 is placed in bossing 62, when detent mechanism 6 will be reused, due to exterior object Intrusion such as sand or the like enter bossing 62 in and cause to be difficult to take out pin 63 to bonding station sometimes.In order to Solves this problem, the cardinal extremity part 63a of pin 63 external diameter is set to be greater than the external diameter for slightly holding part so that is held in pin 63 In the state of putting in bossing 62 between the cardinal extremity part 63a of the inner peripheral surface of bossing 62 and pin 63 outer surface Gap turn narrow to prevent the intrusion of any exterior object.Thus, by preventing the intrusion of exterior object, detent mechanism can be It is properly operated at any time when needing.Therefore, the regulation operation of the length of regulation block selecting drag-line 3 can be greatly improved Operability.
<First embodiment variant of embodiment>
According to above-mentioned embodiment, door 2 guides block selecting bar 1 to four block selecting operating positions.However it is possible that door 2 It is configured to guide block selecting bar 1 to five block selecting operating positions.This embodiment variant of the present invention will hereinafter be entered Row explanation.Pay attention to, will be marked as with the part identical part of above-mentioned embodiment attached with identical in aforementioned embodiments Icon is remembered and therefore will omit the explanation carried out to it.According to first embodiment variant, the present apparatus is applied to have seven The manual transmission of individual pace (pace level) and a reverse speed (reverse speed level).
Block selecting bar 1 is guided to five block selecting operating positions according to the door 21 of first embodiment variant, such as Fig. 9 institutes Show.Compared with the door 2 of prior embodiments, guiding positions of the 7th speed block selecting operating position P5 as door 21 is added.Cause And First Speed-second speed block selecting operating position P1 (" low gear " operating position), third speed-fourth speed block selecting operation Position P2 (N) (neutral gear position), the 5th speed the-the six speed block selecting operating position P3 (" high gear " operating position), for selecting The block selecting operating position P4 and the 7th speed block selecting operating position P5 that reverses gear of reverse speed level arranges along block selecting operation direction Se It is in a row.Thus, according to the first embodiment variant, door 21 thinks the 3rd-the four block selecting operation of the neutral gear position of block selecting bar 1 Block selecting bar 1 is guided to block selecting operating position P1, P3, P4 along block selecting operation direction Se centered on position P2 (N) (neutral gear position) With each block selecting operating position in P5.In other words, the guiding of door 21 carries out the block selecting of block selecting 1 to five block selecting operating position of bar Operation.
Similar with embodiment explained above in first embodiment variant, " low gear " operating position P1 is true It is set to the block selecting operating position specified, while, " high gear " operating position P3 is confirmed as the regulation operating position of block selecting bar 1 P1.However, it is different from " low gear " operating position P1, it is that " high gear " operating position P3 can be for example by selecting the 7th velocity stage Operating physical force needed for Shi Zeng great and mechanically determined.It is to be noted here that as long as " high gear " operation can be determined in vehicle side Position P3, in addition to providing this mechanism, any other device can be applied.
It is to be noted here that according to first remodeling embodiment, as shown in Figure 10 A, the rotation position A2 of cylindrical member 71 (N) minimum point (peak) place that again may be by stopping at cam 74 is mechanically determined.It is in addition, real according to the first modification Mode is applied, as shown in Figure 10 B, the rotation position A5 of cylindrical member 71 is by the contact with base portion 61 of cylindrical member 71 by mechanically It is determined that.Therefore, the outer bar 31 being integrally connected with axle 32 is stopped at the A5 of rotation position, and therefore, is connected by block selecting drag-line 3 The block selecting bar 1 connect is also stopped at the 7th speed block selecting operating position P5.In other words, the 7th speed block selecting operating position P5 quilts The side of outer bar 31 (so-called transmission side) determines.The bias force of spring 73 and cam effect (the cam reaction as caused by cam 74 Power) it is generated to cylindrical member 71 being offset so that the direction indicated by the arrow that ball 72 shows along in as Figure 10 B is moved.
For aforesaid operations, as illustrated in figure 10 c, at the rotation position A3 of cylindrical member 71, ball 72 not yet reaches The minimum point (peak) of cam 74, and in addition, cylindrical member 71 does not contact with base portion 61.Therefore, the rotation of cylindrical member 71 It is not fixed that A3 is put in indexing, but in the minimum point of cam 74 (peak) side shown in arrow of the ball 72 along in as Figure 10 C To mobile mobile status.Thus, rotation position A3 is not determined mechanically.Therefore, the outer bar being integrally connected with axle 32 31 are also at the mobile status moved by the bias force of gigback 7 along neutral displaced position A2 (N) direction and do not stop Only at the A3 of rotation position.Therefore, the block selecting bar 1 connected by block selecting drag-line 3 does not stop at " high gear " operating position P3, and And the position can not mechanically be determined by outer bar 31.
Therefore, in first embodiment variant, predetermined adjustment position is set to rotation position A3.In addition, with it is upper The embodiment of text explanation is similar, and in the case of being set to rotation position A1 in predetermined adjustment position, detent mechanism 6 is by outer bar 31 position determines the rotation position A3 corresponding to " high gear " the operating position P3 with being determined in vehicle side.Then, by its position Put and " high gear " operating position P3 block selecting bar 1 is shifted to by operator and its position is positioned mechanism 6 and determined to rotation position A3 The length (tension force) of block selecting drag-line 3 that connects of outer bar 31 can be conditioned.Thus, " high gear " the operating position P3 of block selecting bar 1 Rotation position A3 with outer bar 31 is by accurately unification.Therefore, when block selecting operation is performed to " high gear " operating position P3, outside Bar 31 is accurately rotated to rotation position A3 and operated so that operating physical force is delivered into block selecting axle 52 so as to perform accurate block selecting.
After the regulation operation of the length of regulation block selecting drag-line is completed, block selecting bar 1 is shifted to the 7th speed by operator Block selecting operating position P5.In other words, operator shifts to block selecting bar 1 for predetermined block selecting operating position from " high gear " position P3 The 7th speed block selecting operating position P5.It is to be noted here that the 7th speed block selecting operating position P5 is located at along block selecting and grasped Make the block selecting operating position that direction Se leaves neutral gear position P2 (N) opening position.
When block selecting bar 1 is shifted to the 7th speed block selecting operating position P5 by operator, connected by block selecting drag-line 3 outer Bar 31 around direction of the axle 32 as pivot along rotation position A5 corresponding with the 7th speed block selecting operating position P5 (i.e., Along the direction for leaving neutral gear position P2 (N)) rotation.Rotation position A3 is in this state positioned at rotation position A5 and neutral displacement Centre position between position A2 (N), and therefore, outer bar 31 overcomes the bias force that gigback 7 applies along rotation position A5 Direction rotates to rotation position A5.
When outer bar 31 rotates along rotation position A5 directions, the engagement quilt between pin 63 and snap ring 65 and bonding part 31a Release.When the engagement is released, the pin 63 for being provided with snap ring 65 is displaced to accommodating position from bonding station and is contained in projection In part 62.In the state of pin 63 has moved to accommodating position, pin 63 and snap ring 65 do not contact with outer bar 31, and because This, outer bar 31 can rotate freely through around axle 32.
After the block selecting of block selecting bar 1 to the 7th speed block selecting operating position P5, if operator by hand from block selecting bar 1 Discharge, then outer bar 31 rotates around axle 32 along neutral displaced position A2 (N) direction (Return-ing direction).With outer bar 31 to neutral displacement In the case of position A2 (N) rotary motion interlocking, block selecting bar 1 returns towards neutral gear position P2 (N).Pass through block selecting bar 1 to sky Gear puts P2 (N) this return, can confirm that pin 63 must be moved to accommodating position and adjust the length of block selecting drag-line 3 The regulation operation of (tension force) is completed.
Therefore, the first embodiment variant can also realize the target effect of the present invention.
<Second embodiment variant>
According to embodiment and the first embodiment variant, the bossing 62 of detent mechanism 6 is formed in (the base portion of housing 5 61) on, and bonding part 31a is arranged in outer bar 31.Thus, it is contained in as the bossing of the bossing at housing side Pin 63 in 62 engages with bonding part 31a.
As shown in figure 11, formed according to the second embodiment variant, bossing 62 in outer bar 31, and pin 63 and bullet Spring 64 is contained in the bossing 62.Thus, snap ring 65 is arranged at the slightly end part 63b of pin 63.In addition, (the shell of base portion 61 Body 5) place can be provided with bonding part 66.
In the second embodiment variant according to structure disclosed above, pin 63 and snap ring 65 connect with bonding part 66 Close.Similar with the structure of embodiment and the structure of the first embodiment variant, outer bar 31 can be positioned accurately and reliably To predetermined adjustment position.In addition, elected pin 1 is operated to predetermined block selecting operating position (for example, the block selecting operating position that reverses gear Similar with the structure of embodiment and the structure of the first embodiment variant when P4), outer bar 31 rotates and pin 63 and snap ring Engagement between 65 and bonding part 66 is released.Therefore, it is similar with embodiment and the first embodiment variant, the second modification Embodiment can also realize the target effect of the present invention.
