DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device having a shock absorbing structure.

[0002]

2. Description of the Related Art As shown in FIG.
2 is attached to the control shaft 204, and the control shaft 204 is
Are supported by a shaft 208 whose both ends are supported.
Thus, when the shift lever 202 is shifted, the control shaft 204 rotates, and a desired shift range can be selected.

[0003] However, when a strong force is applied in the axial direction, the shift lever 202 has a weak absorbing force against this force.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and has as its object to provide a shift lever device which has an improved absorption of a strong force when the force is received.

[0005]

According to the present invention, a shift lever capable of selecting an arbitrary shift range by a shift operation, the shift lever is rotatably supported, and the shift lever is axially moved. And support means for breaking when subjected to an impact force.

Normally, a shift lever is rotatably supported by a support means, and an arbitrary shift range can be selected by a shift operation.

The shift lever has an axial impact force (strong force).
The support means is broken. With this break,
The impact force received by the shift lever can be absorbed.
That is, in the shift lever device of the present invention, the impact force received by the shift lever is absorbed by the breakage of the support means, so that the absorbing force for the impact force is improved as compared with the conventional shift lever device.

[0008] In the second aspect of the present invention, the support means includes a control shaft to which a lower end of the shift lever is connected and which enables the shift lever to rotate in the vehicle longitudinal direction, and a shaft on which the control shaft is supported. It is characterized by having a bearing portion in which a support hole is formed, and an escape hole formed in the bearing portion while leaving a thin portion between the bearing portion.

Normally, since the control shaft is supported by the shaft support hole of the bearing, the shift lever can be operated to rotate the control shaft to select an arbitrary shift range.

When the shift lever receives an impact force in the axial direction, the control shaft presses the thin portion of the bearing, and the thin portion is broken. This break allows the impact force received by the shift lever to be absorbed. The control shaft whose thin portion has been broken enters the escape hole and moves in the direction of the impact force.

As described above, since the relief hole is formed in the bearing portion while leaving the thin portion between the bearing portion and the bearing hole, the impact force can be absorbed without increasing the number of parts.

According to a third aspect of the present invention, the relief hole is a long hole whose width decreases as the distance from the shaft support hole increases.

The control shaft, which breaks the thin portion and enters the escape hole, comes into contact with the hole wall of the elongated hole during the movement and moves while expanding the width of the elongated hole. For this reason, the decay time of the impact force is lengthened, and the impact force can be effectively absorbed.

In the invention described in claim 4, the support means includes a control shaft supported by a bearing portion of the main body, a bracket attached to the control shaft, an insertion hole formed in the bracket, and A pin that is inserted into a shaft hole formed in the shift lever and rotatably supports the shift lever; a thin portion formed in the bracket that breaks when the shift lever receives an impact force in the axial direction; A break portion formed on the thin portion side and breaking when the shift lever receives an impact force in the axial direction.

Normally, a shift lever is rotatably supported on a bracket by a pin, and an arbitrary shift range can be selected by operating the shift lever to rotate the control shaft.

When the shift lever receives an impact force in the axial direction, the thin portion is broken by being pressed by the shift lever, and the broken portion of the pin is also broken. Due to this breakage, a part of the shift lever and the bracket is detached from the control shaft together with the pin, moves in the direction of the impact force, and can absorb the impact force.

As described above, the impact force received by the shift lever can be absorbed by a simple structure in which a thin portion is formed on the bracket and a broken portion is formed on the pin.

In the invention described in claim 5, the support means includes a control shaft supported by a bearing portion of the main body, a bracket attached to the control shaft, an insertion hole formed in the bracket, and A pin that is inserted into a shaft hole formed in the shift lever to rotatably support the shift lever, and that is pressed by the shift lever and broken when the shift lever receives an impact force in the axial direction. I do.

Normally, a shift lever is rotatably supported on a bracket by a pin, and an arbitrary shift range can be selected by operating the shift lever to rotate the control shaft.

When the shift lever receives an impact force in the axial direction, the pin is pressed by the shift lever and breaks, and the shift lever detaches from the bracket together with the pin and moves in the direction of the impact force, thereby absorbing the impact force.

As described above, the shift lever has a simple structure in which the shift lever is rotatably supported on the bracket by the pin which is pressed by the shift lever and breaks when the shift lever receives an impact force in the axial direction. Can absorb the impact force received.

In the invention described in claim 6, the support means includes a control shaft to which a lower end of the shift lever is connected and which enables the shift lever to rotate in the vehicle longitudinal direction, and a shaft on which the control shaft is supported. It has a bearing portion formed with a support hole, and a reduced-diameter portion formed in the control shaft and pressed by the shift lever to break when the shift lever receives an impact force in the axial direction.

Normally, since the control shaft is supported by the shaft support hole of the bearing portion, the user can operate the shift lever to rotate the control shaft to select an arbitrary shift range.

When the shift lever receives an impact force in the axial direction, the control shaft is pressed by the shift lever and the reduced diameter portion is broken. The break causes the shift lever and the control shaft to separate from the bearing portion, move in the direction of the impact force, and absorb the impact force.

As described above, the impact force received by the shift lever is absorbed by breaking the reduced diameter portion formed on the control shaft, so that the structure is simplified without increasing the number of parts.

[0026] In the invention described in claim 7, the support means includes a control shaft to which a lower end of the shift lever is connected and which enables the shift lever to rotate in the vehicle front-rear direction, and a shaft on which the control shaft is supported. A connecting plate having a support hole, a support hole formed in the connecting plate, and a fixing hole formed in the main body frame are inserted into the connecting plate to fix the connecting plate to the main body frame, and the shift lever applies an impact force in the axial direction. And a sure plate that is pressed by the connecting plate and broken when received.

Normally, the control shaft is rotatably supported by the shaft support hole of the connecting plate, and the connecting plate is fixed to the main body plate by the sure plate. Can be selected.

When the shift lever receives an impact force in the axial direction, the connecting plate that supports the control shaft also tends to move in the direction of the impact force. As a result, the sure plate is pressed by the connecting plate and is broken, so that the connecting plate is disengaged from the main frame and moves in the direction of the impact force, thereby absorbing the impact force.

Further, since the shift lever and the connecting plate can be arranged on a straight line, no mounting space is required.

According to the present invention, the support means includes a control shaft supported by a bearing of the main body, a bracket provided below the shift lever, and a support provided on the bracket. Hole, an insertion hole formed in the control shaft and a pin inserted into the shaft support hole, and an escape hole formed in the bracket leaving a thin portion between the shaft support hole. Features.

Normally, a pin is inserted into the shaft support hole of the bracket and the insertion hole of the control shaft, and the user can operate the shift lever to rotate the control shaft to select an arbitrary shift range.

When the shift lever receives an impact force in the axial direction, the bracket at the lower end of the shift lever is pushed toward the pin, and the reaction pushes the pin against the thin portion of the bracket, causing the thin portion to go bankrupt. By breaking the thin part,
The pin moves into the escape hole and can absorb the impact force received by the shift lever.

As described above, the impact force received by the shift lever can be absorbed by a simple structure in which the escape hole is formed by leaving the thin portion in the bracket of the shift lever.

According to the ninth aspect of the present invention, the support means includes a sphere to which a lower end of the shift lever is connected, a sphere receiver for holding the sphere, and a pedestal for rotatably supporting the sphere receiver. And a support portion which is attached to the main body, and which is broken when the shift lever receives an impact force.

Normally, a sphere receiver for holding a sphere is rotatably supported by a cradle, and the cradle is attached to the main body by a support portion. Can be selected.

When the shift lever receives an impact force in the axial direction, the sphere presses the sphere receiver. As a result, the support is also pressed to break the support portion, the support is separated from the main body, and the shift lever moves in the direction of the impact force, so that the impact force can be absorbed.

As described above, since the impact force acts on the support portion via the sphere, the impact force can be reliably absorbed even if the direction of the impact force is blurred or eccentric.

[0038]

1 and 2 show a first embodiment of the present invention.
1 shows a shift lever device 10 according to the embodiment.

The shift lever device 10 has a shift lever 12 for a shift operation.
Is attached to the lever holder 14.

A bracket 16 is formed at the lower end of the lever holder 14 so as to be mounted on a cylindrical control shaft 18. The bracket 16 is connected to the control shaft 18 by a pin 22 so that the lever holder 14 can rotate in the axial direction of the control shaft 18.

The control shaft 18 is supported by a shaft 20. The shaft 20 is connected to a pair of parallel shaft supporting plates 2 erected from the main body of the shift lever device 10.
4 are supported by the four shaft support holes 26. As a result, the shift lever 12 is rotatable about the shaft 20 in the front-rear direction of the vehicle, and is further rotatable about the pin 22 in the width direction of the vehicle.

An intensity gate is provided in the main body of the shift lever device 10, and when the shift lever 12 in the D range (2 or L range depending on the case) rotates in the direction of the N range, the N wall of the intensity gate is provided. At 34, it is stopped at the position of the N range (the position indicated by the solid line in FIG. 2) so that it does not accidentally enter the R range or the P range (the position indicated by the two-dot chain line in FIG. 2). When the shift lever 12 is rotated in the width direction of the vehicle around the pin 22, the shift lever 12 does not hit the N wall 34 and the R range or the P range
Can be put into range.

A control lever (not shown) protrudes from the control shaft 18, and a pin of the control lever is connected to the automatic transmission via a transmission mechanism, and the automatic transmission is shifted by operating the shift lever 12. Has become.

The shaft 20 supported by the shaft support hole 26 is
One end is retained by a push nut 21. An enlarged diameter portion 20A is formed at the other end of the shaft 20 and is prevented from falling off. Reinforcing ribs 38 are formed between the support plates 24 to reinforce the support plates 24.

As shown in FIG. 2, the shaft support plate 24 is formed with a long hole-shaped relief hole 30 except for a predetermined thin portion 28 between the shaft support hole 26 and the shaft support hole 26. The thickness of the thin portion 28 is the same for the left and right pivot plates. Also, the escape hole 30
Are formed parallel to the axial direction of the shift lever 12 when the shift lever 12 is in the N range. The width of the escape hole 30 gradually decreases as the distance from the shaft support hole 26 increases, and the width of the escape hole 30 is substantially the same as the shaft diameter of the shaft 20 at a substantially middle portion.

Therefore, when the shift lever 12 is in the N range and receives an impact force in the axial direction, the impact force causes the shaft 20 to press the thin portion 28, and the thin portion 28 is broken. This break absorbs the impact force and moves the shaft 20 further into the escape hole 30. Further, since the width of the escape hole 30 gradually decreases as the distance from the shaft support hole 26 increases, as shown in FIG. 4, the shaft 20 hits the hole wall of the escape hole 30 during the movement, and the width of the escape hole 30 is reduced. Move while spreading. This causes a resistance to the movement of the shaft 20,
The decay time of the impact force is increased, so that the impact force can be absorbed more effectively.

When the movement of the shaft 20 having moved through the escape hole 30 has stopped, the shift lever 12 enters the center console 36 as shown in FIG. It is almost flush with the seat. For this reason, the possibility that the occupant or the load will hit the shift lever 12 again is reduced.

It should be noted that the above-mentioned impact force is shown in FIG.
As shown in the figure, the force F is applied along the axis J of the shift lever 12.
When this acts, this force F is referred to as shown in FIG.
As shown in FIG.
Acts obliquely, of the component Fy of the force J in the direction of the axis J and the component Fx in the direction perpendicular thereto, the component Fy in the direction of the axis J. (In the following description, the impact force is similarly defined.) Therefore, not only when the force F acts along the axis J of the shift lever 12, but also when the shift lever 1
This force F can be absorbed even when it acts obliquely with respect to the axis 2.

Next, the operation of the shift lever device 10 according to the first embodiment will be described. In a normal use state, the shaft 20 is supported by the shaft support hole 26. Therefore, when the shift lever 12 is operated to rotate the lever holder 14, the control shaft 18 also rotates, and an arbitrary shift range is selected. it can.

When the vehicle is running, the shift lever 12 is in the D range (2 or L range depending on the case). When the shift lever 12 receives an impact force, for example, when the vehicle is suddenly decelerated, the shift lever 12 first moves to the D range. Move from range to N range. In the N range, since the shift lever 12 hits the N wall 34, the shift lever 12 does not accidentally move to the R range or the P range.

Next, the shaft 20 presses the thin portion 28 by the impact force, and the thin portion 28 is broken. The breaking force absorbs the impact force.

The shaft 20 whose thin portion 28 is broken moves into the escape hole 30 as shown in FIG.
The width of the escape hole 30 gradually decreases as the distance from the shaft support hole 26 increases, and the width of the escape hole 30 substantially at the intermediate portion is reduced by the shaft 20.
, The shaft 20 hits the hole wall of the escape hole 30 during the movement, and moves while expanding the width of the escape hole 30. Thereby, the shaft 2
A resistance is generated in the movement of 0, and the decay time of the impact force becomes longer, so that the impact force can be absorbed more effectively.

As described above, in the shift lever device 10 according to the first embodiment, the shaft 20 breaks the thin portion 28 when the shift lever receives an impact force. In comparison, the absorbing power for the impact force is improved. Further, the impact force received by the shift lever 12 can be absorbed without increasing the number of parts.

In the shift lever device 10, the magnitude of the impact force at which the thin portion 28 is broken can be arbitrarily adjusted by changing the thickness of the thin portion 28.

The shape of the escape hole 30 is not limited to the above-described one, and may be, for example, a gently curved one.

FIGS. 6 and 7 show a shift lever device 40 according to a second embodiment of the present invention.

The shift lever device 40 has a substantially U-shaped rotating bracket 42, and an insertion hole 46 is formed in the end plate 44 of the rotating bracket 42 facing the rotating bracket 42. A control shaft 48 is inserted through the insertion hole 46, and the control shaft 48 is
It is also rotatable together. Control shaft 4
An enlarged diameter portion 48A is formed at the end of 8 to prevent it from falling off.

Further, the control shaft 48 is
Similarly to the embodiment, the shift lever device 40 is rotatably supported by a pair of parallel shaft support plates (not shown) erected from the main body of the shift lever device 40.

A substantially L-shaped support bracket 50 is provided at a substantially middle portion in the longitudinal direction of the rotating bracket 42 in a side view. A thin portion 52 is formed at the base of the support bracket 50 to reduce the strength. When the support bracket 50 receives a force equal to or more than a predetermined value from above, the thin portion 52 is broken as shown in FIG. Support bracket 50
Is detached from the rotating bracket 42.

Further, a support hole 54 (see FIG. 7) and a support hole 56 are formed coaxially in the rotation bracket 42 and the support bracket 50, respectively. Rotating bracket 4
A lower end of a shift lever 60 having a shaft hole 58 (see FIG. 7) is disposed between the support lever 2 and the support bracket 50.
The pin 62 is inserted into the support hole 54, the shaft hole 58, and the support hole 56, and the shift lever 60 is supported by the shaft. Thus, the shift lever 60 is rotatable around the control shaft 48 in the front-rear direction of the vehicle, and is further rotatable around the pin 62 in the width direction of the vehicle.

The pin 62 is formed at one end with an enlarged diameter portion 66 having a diameter larger than the shaft diameter of the pin 62. When the pin 62 is inserted into the support hole 54, the shaft hole 58 and the support hole 56, the diameter is increased. The portion 66 is positioned against the rotating bracket 42.

In the pin 62, a break hole 64 is cut out at a predetermined length from one end side in the axial direction, and the break portion 6 is formed.
5 are formed, and the strength is weakened. As a result, as shown in FIG. 8, when a force equal to or more than a predetermined value is applied from a direction perpendicular to the axial direction, the pin 62 is broken at the break portion 65.

At the other end of the pin 62, a caulking portion 68 smaller than the shaft diameter of the pin 62 is formed. After the pin 62 is inserted through the support hole 54, the shaft hole 58, and the support hole 56, the caulked portion 68 is caulked and the diameter is expanded, so that the pin 62 is prevented from coming off.

In the shift lever device 40, in a normal use state, the lower end of the shift lever 60 is disposed between the rotating bracket 42 and the support bracket 50 as shown in FIG. Therefore, the user can operate the shift lever 60 to rotate the control shaft 48 to select an arbitrary shift range.

When the shift lever 60 receives an impact force in the axial direction, for example, during rapid deceleration of the vehicle, the shift lever 60 presses the pin 62 as shown in FIG.
Is broken at The thin portion 52 of the rotating bracket 42
Is also broken. Due to this break, the impact force received by the shift lever 60 is absorbed. Further, the shift lever 60 and the support bracket 50 move downward while being integrated by the pin 62.

As described above, the thin portion 52 is attached to the bracket 42.
And the impact force received by the shift lever 60 can be absorbed by a simple structure in which the break portion 65 is simply formed in the pin 62.

FIGS. 9 and 10 show a shift lever device 70 which is a modification of the shift lever device 40 according to the second embodiment of the present invention.

In this shift lever device 70, similarly to the shift lever device 40 according to the second embodiment of the present invention, a substantially U-shaped rotating bracket 72 is provided with a substantially L
Although a U-shaped support bracket 74 is provided, a thin portion is not formed at the base of the support bracket 74. As shown in FIG. 11, the two bottom plates 74A of the support bracket 74 gradually widen toward the rotation bracket 72, and the space between these bottom plates 74A has a substantially trapezoidal shape larger than the cross section of the shift lever 76. A through hole 78 is formed.

Similarly to the shift lever device 40, the lower end of the shift lever 76 is provided between the rotation bracket 72 and the support bracket 74, and is supported by a pin 80. The pin 80 has a broken portion 82 formed by cutting a predetermined length of a broken hole 82 from one end side along the axial direction, and a broken portion 83 is formed. The strength of the broken portion 83 is reduced.

On the other hand, the other end of the pin 80 is provided with a rivet hole 8.
4 are formed, and the rivet hole 82 is a broken portion 85 having low strength. A rivet 86 is inserted into the rivet hole 84 and swaged, and the pin 80
Is to keep out.

Therefore, in this shift lever device 70,
As shown in FIG. 12, when an impact force of a predetermined value or more is applied in the axial direction of the shift lever 72, the pin 80 is broken at the break hole 82 and is broken along with the rivet 86 at the rivet hole 84, The impact force is absorbed. Since the support bracket 74 has no thin portion, only the shift lever 76 moves downward through the through hole 78 while the support bracket 74 is integrated with the rotation bracket 72.

FIG. 13 shows a shift lever device 90 according to a third embodiment of the present invention.

In the shift lever device 90, the lower end of the shift lever 92 is attached to the retainer 94. The retainer 94 has a substantially inverted T-shape, and the lower end of the shift lever 92 is inserted into and fixed to a tubular mounting portion 96 erected substantially at the center.

A substantially horizontal portion of the retainer 94 is formed as a cylindrical insertion portion 98. A bush 100 is fitted into both ends, and a control shaft 102 is inserted therethrough.

On the other hand, a pair of bearing plates 106 extend downward from the main body plate 104, and a shaft support hole 108 for supporting the control shaft 102 is formed in the center of the bearing plate 106. ing.

An enlarged diameter portion 102A is formed at one end of the control shaft 102, and the other end of the control shaft 102 is reduced in diameter.
2B is cut off. In a state where the control shaft 102 is supported by the shaft support hole 108, one end side has the enlarged diameter portion 10.
2A, the other end is a male screw 102B
The nut 110 is screwed into the nut to prevent the nut from coming off. In this state, the user can operate the shift lever 92 to select an arbitrary shift range.

A substantially wedge-shaped hollow portion 112 is formed in the control shaft 102 from one end to the other end. A reduced diameter portion 114 cut from the outer periphery toward the center is formed inside the portion of the control shaft 102 which is supported by the shaft support hole 108.
For this reason, the strength of the control shaft 102 is weak in the portion where the reduced diameter portion 114 is formed.

Also in the shift lever device 90, since the control shaft 102 is normally supported by the shaft support hole 108, the shift lever 92 is operated to rotate the control shaft 102, and an arbitrary shift range is set. You can choose.

When the shift lever 92 receives an impact force in the axial direction, as shown in FIG.
The second reduced diameter portion 114 is broken. By this break, the impact force received by the shift lever 92 can be absorbed,
The control shaft 102 falls down leaving both ends.

Further, the impact force received by the shift lever 92 can be absorbed by a simple structure in which only the reduced diameter portion is formed on the control shaft 102.

As described above, the control shaft 102
Since the impact force received by the shift lever 92 is absorbed by the breakage of the reduced diameter portion 114 formed in the above, the structure is simplified without increasing the number of parts.

It should be noted that the fracture of the right and left reduced diameter portions 114 does not always have to be simultaneous. For example, the size of the hollow portion 112 is adjusted to change the cross-sectional area of the left and right reduced diameter portions 114 so that there is a time difference in the fracture. May occur.

FIG. 15 shows a shift lever device 120 according to a fourth embodiment of the present invention.

In the shift lever device 120, the main body frame 122 is extended downward to form a pair of mounting plates 124. The mounting plates 124 have substantially inverted triangular connecting plates 126 also shown in FIG. Can be attached. That is, the secure plate 132 is inserted into the horizontally long fixing holes 128 formed in the mounting plate 124 and the horizontally long supporting holes 130 formed on the upper part of the connecting plate 126, and the connecting plate 126 is attached to the mounting plate 124. Have been. After the sure plate 132 is inserted through the fixing hole 128 and the support hole 130, both ends in the insertion direction are caulked and are prevented from coming off. Further, the sure plate 132 is formed of a material having lower strength than the mounting plate 124 and the connecting plate 126.

On the other hand, the lower end of the shift lever 138 is attached to a retainer 140, and a control shaft 134 is inserted through an insertion portion 142 of the retainer 140. Further, a shaft support hole 136 is provided at a lower portion of the connection plate 126.
The control shaft 134 is supported in the shaft support hole 136. As a result, the shift lever 138 can be operated and rotated to select an arbitrary shift range.

In this shift lever device 120,
Normally, the connecting plate 126 is mounted on the mounting plate 124, the control shaft 134 is supported by the shaft support hole 136, and the insertion portion 142 of the retainer 140 is supported by the control shaft 134. Therefore, the user can operate the shift lever 138 to rotate the control shaft 134 to select an arbitrary shift range.

When the shift lever 138 receives an impact force in the axial direction, the impact force is transmitted via the retainer 140, the control shaft 134, and the connecting plate 126 to the sure plate 132.
17 and as shown in FIG.
Is broken. Due to this break, the connecting plate 126 falls down, and the impact force received by the shift lever 138 can be absorbed. In addition, the breakage of the sure plate 138
There may be a time difference between left and right.

Further, the shift lever 138 and the sure plate 132 are arranged in a straight line,
No special space is required for mounting 2.

FIG. 18 shows a shift lever device 150 according to a fifth embodiment of the present invention.

In the shift lever device 150, the lower end of the shift lever 152 is attached to the lever holder 154. The lever holder 154 is bent at a substantially intermediate portion, and a bracket 156 formed of a pair of parallel plate pairs is formed below the lever holder 154.

The bracket 156 has a shaft support hole 158.
(See FIG. 19), and the pin 16 is positioned with the bracket 156 straddling the control shaft 160.
2 is inserted through the shaft support hole 158, and the lever holder 154 is rotatably supported by the control shaft 160. Further, similarly to the shift lever device 10 according to the first embodiment, the control shaft 160 is supported by a shaft support hole (not shown) of a main body. As a result, the shift lever 152 moves the control shaft 1
The vehicle can rotate in the front-rear direction of the vehicle around the axis 60, and can also rotate in the vehicle width direction around the pin 162.

A long escape hole 166 is formed above the shaft support hole 158 except for a predetermined thin portion 164 between the shaft support hole 158 and the shaft support hole 158.

In this shift lever device 150, normally, the lever holder 154 is mounted on the control shaft 160.
, The shift lever 162 can be operated to select an arbitrary shift range.

When the shift lever 162 receives an impact force in the axial direction, as shown in FIG.
2, the thin portion 164 is moved by the reaction
Thus, the impact force received by the shift lever 162 can be absorbed. In addition, the thin portion 164
As a result, the lever holder 154 falls downward, and the pin 162 enters the escape hole 166.

As described above, the impact force received by the shift lever 162 can be absorbed by a simple structure in which the escape hole 166 is formed by leaving the thin portion 164 in the bracket 156 of the shift lever 162.

In this shift lever device 150,
The width of the escape hole 166 may be gradually reduced as going upward, so that the pin 162 that has entered the escape hole 166 may hit the hole wall of the escape hole 166. As a result, while the lever holder 154 is falling downward,
62 moves while the width of the escape hole 166 is pushed and widened, so that the decay time of the impact force is lengthened and the impact force can be absorbed more effectively.

Further, since the lever holder 154 is bent at a substantially intermediate portion, the impact force received by the lever holder 154 is not directly transmitted to the control shaft 160.

FIGS. 20 and 21 show a shift lever device 170 according to a sixth embodiment of the present invention.

In this shift lever device 170, the shift lever 172 is inserted into the guide hole 176 of the cover plate 174, and the lower end of the shift lever 172 is further erected from a substantially spherical control sphere 178.
Screwed into 80. The cover plate 172 is screwed to the shift lever plate 188.

The lower half of the control sphere 178 is in surface contact with the inner surface of a control cable 184 formed in a substantially hemispherical shape, and holds the control sphere 178.
