[0002]
[Prior art]
As shown in FIG. 6, the conventional shift lever 80 device includes a shift lever 82 that is connected to the transmission of the vehicle and changes the shift range of the transmission. A shaft 84 is formed at the lower end of the shift lever 82, and the shaft 84 is pivotally supported by a pair of side walls 88 formed integrally with a resin base plate 86.
[0003]
A knob 90 is attached to the tip of the shaft 84, and a release button 34 (see FIG. 1) is movably provided on the knob 90. Further, a detent pin 92 extends toward the both side walls 88 at an intermediate portion of the shift lever 82, and a tip thereof engages with a detent hole 94 described later. When changing the shift range, the detent pin 92 is pushed down by pushing the release lever 34, and the shift lever 82 is turned.
[0004]
Further, a mounting base 96 is provided at a substantially intermediate portion of the shift lever 82, and a cylindrical pin 98 and a through hole 100 are formed in the mounting base 96, respectively. Then, one end of the moderation piece 102 is passed through the through hole 100, and the pin 98 is fitted into a circular hole formed in advance in the moderation piece 102, so that the moderation piece 102 is attached with one touch. Further, the distal end portion of the moderation piece 102 is curved to be engaged with a moderation groove 104 described later.
[0005]
On the other hand, as shown in FIG. 6, a moderation plate 106 that is engaged with the tip of the moderation piece 102 is attached to the base plate 86. The moderation plate 106 is formed with a plurality of moderation grooves 104 corresponding to each shift range (P range, R range, N range, etc.). As the shift position of the shift lever 82 is changed, the moderation piece 102 is also changed. The front end of the shift lever 82 is moved and engaged with the moderation groove 104 corresponding to the shift position of the shift lever 82.
[0006]
[Problems to be solved by the invention]
By the way, when attaching the moderation piece 102 to the shift lever 82, first, after the shaft 84 of the shift lever 82 is pivotally supported on the side wall 88 of the base plate 86, the tip of the moderation piece 102 does not engage with the moderation groove 104. Thus, the moderation piece 102 had to be bent and attached to the opposite side of the moderation plate 106 with the hand 108. For this reason, the mounting work of the moderation piece 102 is troublesome.
[0007]
Then, this invention makes it a subject to provide the shift lever apparatus which can be easily attached to a shift lever, without bending a moderation piece.
[0008]
[Means for Solving the Problems]
The shift lever device according to claim 1 is connected to a transmission of a vehicle, and is provided on a shift lever that changes a shift range of the transmission by a shift operation, a support that pivotally supports the shift lever, and the shift lever. A detent pin that moves integrally with the shift lever along the shift operation direction along with the shift operation, and the shift lever moves from a shift position corresponding to the shift range to a shift position corresponding to another shift range by engaging with the detent pin. A detent hole for restricting, a moderation piece having elasticity with a curved tip attached to the shift lever, and a plurality of engagement portions formed corresponding to each shift range and engaged with the tip of the moderation piece in each shift range A moderation plate with moderation grooves and a detent hole are formed continuously, and the detent pin is inserted to move the shift lever out of the shift range. Avoidance hole for, is formed in the detent plate, the detent piece by positioning the shift lever to the shift range when attached to the shift lever, avoiding contact with the tip and nodal degree plate of the detent piece And an avoidance groove .
[0009]
According to this configuration, the moderation piece whose tip is curved is attached to the shift lever. The moderation piece is attached to the shift lever with the shift lever attached to the support, the detent pin of the shift lever entering the avoidance hole, and the shift lever positioned outside the shift range. For this reason, the moderation piece can be attached to the shift lever while avoiding the engagement between the tip of the moderation piece and the plurality of moderation grooves formed in the moderation plate.
[0010]
As a result, it is not necessary to bend the moderation piece to the opposite side of the moderation plate in advance so that the tip of the moderation piece does not engage the moderation groove when attaching the moderation piece. Can be easily performed.
[0011]
On the other hand, since the avoidance hole is formed continuously with the detent hole after the moderation piece is attached to the shift lever, the detent pin can be engaged with the detent hole from the avoidance hole by turning the shift lever as it is. it can. At this time, the moderation piece also moves with the movement of the shift lever and engages with the moderation groove corresponding to each shift range. Thereby, the shift operation of the shift lever becomes possible and a normal traveling state can be obtained.
[0013]
The moderation piece is attached to the shift lever with the detent pin entering the avoidance hole and the shift lever positioned outside the shift range. At this time, contact between the tip of the moderation piece and the moderation plate can be avoided by the moderation groove formed in the moderation plate. For this reason, since the moderation piece does not come into contact with the moderation plate and is not deformed at the time of attachment, the moderation piece can be attached more easily.
[0014]
The shift lever device according to claim 2 is a shift lever device that changes a shift range by pushing down a release button provided on the shift lever to depress the detent pin, and the detent pin is pushed by the detent pin. It is characterized by being set smaller than the pressing amount required to enter the avoidance hole.
[0015]
According to this configuration, after the moderation piece is attached to the shift lever, the shift lever is pivoted and the detent pin is engaged with the detent hole, thereby enabling a traveling state corresponding to each shift range. The shift range can be changed by pressing the release button and depressing the detent pin.
[0016]
Here, the pressing amount of the release button is set to be smaller than the pressing amount necessary for the detent pin to enter the avoidance hole, so when the detent pin is engaged with the detent hole, it is released during traveling. Even if the button is pushed by mistake, the detent pin does not enter the avoidance hole, and safety and stability during traveling can be ensured.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a shift lever device according to an embodiment of the present invention will be described with reference to the accompanying drawings.
[0018]
As shown in FIG. 1, the shift lever device 12 includes a shift lever 10. The shift lever 10 includes a pipe-like lever body 14 that is elongated along the vehicle vertical direction (arrow UP in FIG. 1 and the opposite direction). A shaft 16 is formed at the lower end portion of the lever main body 14 so as to have a substantially vehicle left-right direction (arrow LF in FIG. 1 and the opposite direction thereof) as an axial direction, and is erected from both ends of the base plate 18 in the vehicle left-right direction. Are supported by the bearing holes 22 of the pair of side walls 20 facing each other.
[0019]
Further, a wire locking portion 24 in which one end of a wire (not shown) is locked protrudes from the outer peripheral portion of the lever main body 14. The other end of the wire is mechanically coupled to an automatic transmission (not shown) of the vehicle directly or indirectly through a coupling means such as a link mechanism, and the lever main body 14 is rotated around the bearing hole 22. The shift range set in the automatic transmission is changed by pulling or returning the wire in accordance with the turning position (shift position).

The detent rod 42 is always urged upward by a compression spring (not shown) disposed in the vicinity of the lower end portion of the vertical hole 40. Therefore, the upper end portion of the detent rod 42 is always released from the release button 34. The release button 34 is pressed downward by the pressing force when the release button 34 is pressed.
[0024]
The pressing amount of the release button 34 is set to be smaller than the pressing amount necessary for the detent pin 44 to enter the avoidance hole 72 described later, and the detent pin 44 once enters the detent hole 48 from the avoidance hole 72. Then, even if the release button 34 is pushed, the detent pin 44 cannot enter the avoidance hole 72 again.
[0025]
A tubular sleeve 58 is slidably accommodated in the vertical hole 38 of the knob 30, and the detent rod 42 penetrates the sleeve 58 so as to be relatively movable. A compression coil spring 62 is disposed below the sleeve 58, and the compression coil spring 62 urges the sleeve 58 upward and always abuts against the cam 36 formed at the end of the release button 34. It touches.
[0026]
Further, a detent pin 44 is formed so as to project from the intermediate portion in the longitudinal direction of the detent rod 42 toward both sides in the vehicle lateral direction. The detent pin 44 passes through a longitudinal slit hole 46 formed in the lever main body 14 in a substantially vertical direction of the vehicle, and a tip part thereof enters a detent hole 48 formed in the side wall 20.
[0027]
Further, as shown in FIG. 4, a mounting base 64 is integrally formed with the lever main body 14 in the vicinity where the slit hole 46 is formed (the direction opposite to the FR shown in FIG. 1). The mounting table 64 is formed in a wedge shape as a whole, and a cylindrical pin 66 is formed on the upper surface thereof. Further, a support piece 64A protrudes in the vicinity of the pin 66, and a through hole 64B through which the moderation piece 68 passes is formed in the support piece 64A.
[0028]
The moderation piece 68 has a straight body portion 68A, and the front end portion 68B of the body portion 68A is curved. A circular hole 70 into which the pin 66 is fitted is formed at the rear end of the body portion 68A.
[0029]
Therefore, the moderation piece 68 is attached to the shift lever 10 by one touch by passing the rear end of the moderation piece 68 through the through hole 64B and fitting the circular hole 70 into the pin 66. The moderation piece 68 may be made of metal, resin, or the like as long as it has a predetermined elastic force.
[0030]
As shown in FIGS. 1 and 2, the detent hole 48 pivots around the bearing hole 22 in a state in which the radius of curvature of the upper inner periphery 50 is located at the upper end of the slit hole 46 or in the vicinity thereof. The detent pin 44 moves along the upper inner peripheral portion 50 when the lever main body 14 turns.
[0031]
Further, a restriction wall 54 protrudes from a part of the upper inner peripheral portion 50 toward the lower inner peripheral portion 52. This limiting wall 54 is a turning position (shift position) of the lever body 14 corresponding to the neutral range of the automatic transmission that allows the drive wheels of the vehicle to freely rotate, that is, the "N" formed in the housing 26. The turning position of the lever body 14 corresponding to the turning position on the side of the character (hereinafter referred to as “N position”) and the parking range of the automatic transmission that locks the driving wheels of the vehicle, that is, the housing 26 is formed. Further, it is formed corresponding to the turning trajectory of the detent pin 44 when the lever main body 14 is turned between the side turning position of the letter “P” (hereinafter referred to as “P position”), When the lever body 14 is turned with the detent pin 44 positioned at the upper end of the slit hole 46 or in the vicinity of the slit hole 46, the limiting wall 54 comes into contact with the slit hole 46 and the lever is indirectly lifted. To limit the turning of the body 14.
[0032]
Further, as shown in FIGS. 1 and 2, a step portion whose height is set between the lower end portion of the restriction wall 54 and the upper inner peripheral portion 50 is located behind the lower end portion of the restriction wall 54. 56 is formed. The step 56 is a turning position (shift position) of the lever body 14 corresponding to the reverse range of the automatic transmission that reversely drives the driving wheels of the vehicle, that is, the side of the letter “R” formed on the housing 26. Corresponds to the turning position of the detent pin 44 when the lever body 14 is located at the turning position (hereinafter referred to as “R position”).
[0033]
Further, as shown in FIGS. 1 and 2, a rectangular avoidance hole 72 is formed continuously (communicatively) in the lower inner peripheral portion 52 corresponding to the L range groove of the detent hole 48. Although the details will be described later in the avoidance hole 72, the detent pin 44 is positioned when the moderation piece 68 is attached to the shift lever 10.
[0034]
On the other hand, a moderation plate 74 (moderation mountain) is attached to the base plate 18 between the pair of side walls 20. For this attachment, the moderation plate 74 may be formed integrally with the base plate 18, or after the base plate 18 is molded, it may be strongly bonded to the base plate 18 or screwed. The moderation plate 74 is formed with a plurality of moderation grooves 76 corresponding to each shift range.
[0035]
Specifically, as shown in FIG. 2, the moderation plate 74 is formed with an L range groove 76A that engages with the tip 68B of the moderation piece 68 when the shift lever 10 is in the L range. A two-range groove 76 </ b> B that engages with the tip of the moderation piece 68 when the lever 10 is positioned in the two-range is formed. In this manner, the moderation plate 76 is formed with other D range grooves 76C, N range grooves 76D, R range grooves 76E, and P range grooves 76F.
[0036]
As shown in FIG. 2, an avoidance groove 78 is formed below the L range groove 76A. The avoidance groove 78 is formed deeper than the moderation grooves 76. The avoidance groove 78 is inserted into the tip 68B of the moderation piece 68 when the detent pin 44 of the shift lever 10 is positioned in the avoidance hole 72 and the moderation piece 68 is attached to the mounting base 64 of the shift lever 10. It is a groove which avoids contact with.
[0037]
Next, the operation of the shift lever device according to this embodiment will be described.
[0038]
A process for attaching the moderation piece 68 to the shift lever 10 will be described. First, the shaft 16 at the lower end of the shift lever 10 is fitted into the bearing hole 22 of the base plate 18. Then, after the detent pin 44 of the shift lever 10 is pushed down directly against the compression spring, the detent pin 44 is caused to enter the avoidance hole 72 and the shift lever 10 is tilted out of the shift range.
[0039]
In this state, as shown in FIG. 5, the curved tip end portion 68 </ b> B of the moderation piece 68 is positioned in the avoidance groove 78. Next, the moderation piece 68 is moved in the direction of arrow A, and the rear end of the moderation piece 68 is passed through the through hole 64B of the support piece 64A. Then, a circular hole 70 formed at the rear end of the moderation piece 68 is fitted into the pin 66 formed on the mounting base 64.
[0040]
In this way, the shift lever 10 is tilted out of the shift range, so that the tip portion 68B of the moderation piece 68 does not engage with the moderation groove 76, and the tip portion 68B of the moderation piece 68 is positioned in the avoidance groove 78. Without touching the plate 74, the straightness of the moderation piece 68 can be maintained and attached as it is with one touch. As a result, the mounting operation can be facilitated.
[0041]
On the other hand, after the moderation piece 68 is attached to the mounting base 64 of the shift lever 10, the shift lever 10 is raised so that the detent pin 44 is positioned at a continuous portion (communication portion 72 </ b> A) between the avoidance hole 72 and the detent hole 48.
[0042]
When the detent pin 44 is positioned at the communication portion 72A, as shown in FIG. 3, the detent rod 42 is pushed upward by a compression spring (not shown) provided at the lower portion of the detent rod 42, and the detent pin 44 is directly moved into the detent hole. Enter 48. Then, when the detent pin 44 enters the detent hole 48, the vehicle can normally travel.
[0043]
When the shift range is changed by the shift operation of the shift lever 10, the tip end portion 68B of the moderation piece 68 is engaged with the moderation groove 76 corresponding to each shift range, thereby providing a moderation feeling (click feeling). Thus, the driver can easily confirm the shift position of the shift lever 10.
[0044]
For example, when shifting from the 2 range to the L range, the upper end of the detent rod 42 is pushed downward by the cam 36 by pressing the release button 34. When the shift lever 10 is in the L range, the pushing amount of the release button 34 is set to be smaller than the pushing amount of the detent pin 44. Therefore, even if the release button 34 is pushed, the detent pin 44 remains on the lower inner circumference. It only moves to the part 52 and does not enter the avoidance hole 72. Even if the shift lever 10 is tilted with the detent pin 44 moved to the lower inner peripheral portion 52, the detent pin 44 is in contact with the corner portion 48 </ b> A of the detent hole 48. No entry into 72. For this reason, the safety and stability of driving | running | working are securable.
[0045]
