Description

  The present invention relates to a shift lever device for operating a transmission such as a vehicle.

  A plurality of shift ranges are set in advance in the automatic transmission of the vehicle, and an operation device for selecting and operating the plurality of shift ranges is provided in the vehicle. As this type of operating device, a so-called shift lever device is often used. The shift lever device includes a substantially rod-shaped shift lever. The shift lever can be swung around a predetermined portion on the base end side in the longitudinal direction.

  When the shift lever is swung and the shift lever reaches a predetermined shift position set in advance, for example, the position of the shift lever is detected by position detecting means such as a micro switch or a magnetic sensor, and based on the detection result An electric signal is input to an ECU constituting the automatic transmission. The ECU of the automatic transmission to which this electric signal is input is configured to determine that the shift lever has reached a predetermined shift position and to change the shift range of the automatic transmission to a shift position corresponding to the shift position. .

  On the other hand, when changing a shift register from a plurality of shift ranges set in the automatic transmission to another shift range from a parking range used for parking (hereinafter referred to as “P range”), for example, If the brake pedal is not depressed, the shift lever device is provided with a so-called “P shift lock mechanism” that regulates the swing operation of the shift lever in a direction away from the P position, which is a shift position corresponding to the P range. An example of a shift lever device provided with a “P shift lock mechanism” is disclosed in Patent Document 1 below.

  The P shift lock mechanism disclosed in Patent Document 1 includes a shift lock solenoid. The shift lock solenoid has a winding, and is a so-called electromagnet that generates a magnetic force by energizing the winding.

  The shift lock solenoid is integrally provided with a yoke formed of a magnetic material such as iron. When the shift lock solenoid is energized and energized, the yoke is magnetized.

  A cam member having a slope is provided on the yoke. The slope of the cam member is formed so that the lever provided integrally with the shift lever faces in the state where the shift lever is located at the P position. Presses against the slope. The cam member is configured to slide with a shift lock solenoid when the inclined surface receives a pressing force from the lever.

  A stopper is provided on the opposite side of the shift lock solenoid via the cam member. The stopper is made of a magnetic material such as iron, and can be slid independently of the cam member in the same direction as the cam member.

  When the shift lever is moved to move away from the P position, the lever presses and moves the inclined surface of the cam member as described above. However, since the stopper is slidable independently of the cam member, The stopper does not slide even when moved. When the stopper is brought into contact with and interferes with the lever on which the cam member is slid, the movement of the shift lever in the direction away from the P position is restricted.

  On the other hand, when a predetermined operation such as depression of the brake pedal of the foot brake is performed, a current flows through the shift lock solenoid and the shift lock solenoid is excited. When the yoke, and thus the cam member, is magnetized by exciting the shift lock solenoid, the stopper is attracted to the cam member and integrated.

In this state, when the lever presses the slope of the cam member and slides the cam member as described above, the stopper slides with the cam member. In this way, the lever slides away from the movement path of the lever so that the lever does not receive interference from the stopper. As a result, the shift lever can be detached from the P position and moved to a shift position corresponding to a shift range different from the parking range.

  By the way, the shift lock solenoid used in the shift lever device as described above is configured such that the shift lock solenoid slides together with the cam member. For this reason, the power supply member such as a cord for electrically connecting the shift lock solenoid and the power source does not bend the power supply member so that it can move with the shift lock solenoid. must not.

  In addition, considering that the shift lock solenoid is slid several times, it is firmly connected so that the electrical connection between the power supply member and the shift lock solenoid can be maintained even if the power supply member repeatedly moves with such sliding. I have to do it.

  The present invention has been made in view of the above facts, and has an object to obtain a shift lever device that does not need to bend and install a power supply member to an electromagnet and that does not require excessively strong connection with an electromagnet. It is.

  In the shift lever device according to the first aspect of the present invention, any one of the shift positions can be obtained by moving the shift lever toward any one of a plurality of preset shift positions. A shift lever device that operates a transmission mounted on the vehicle in response to an engagement member provided on the shift lever to be movable between an engagement position and an engagement avoidance position, and the engagement First urging means for urging the engaging member toward the position side, and movement of the shift lever to a specific shift position and the shift from the specific shift position among the plurality of shift positions. A restricting means provided to be able to interfere with the engaging member located at the engaging position to be moved in accordance with any one of the movements of the lever, and indirectly restricting the one of the movements by the interference. And the lock position And the unlocking position so as to be displaceable, and abut against the engaging member that moves with the movement of either one of the engaging member in the state of being in the engaging position before the regulating means. The engagement member is moved to the engagement avoidance position that avoids interference from the restricting means by contacting the engagement member while being positioned at the unlocked position. An interference avoiding means for receiving a pressing force from the unlocked position toward the locked position by contacting the engaging member; and the first biasing when the interference avoiding means contacts the engaging member. A second urging means for urging the interference avoiding means toward the lock release position with an urging force smaller than the pressing force based on the urging force of the means, and the interference avoiding means by a magnetic force generated by energization. When adsorbed To is characterized in that it comprises a shift lock device the resultant force of the biasing force is configured by including, an electromagnet exceeds the pressing force of the suction force and the second biasing means based on the magnetic force.

  In the shift lever device according to the first aspect of the present invention, when the shift lever is moved to any one of a plurality of preset shift positions, according to any one of the shift positions. A transmission mounted on the vehicle is operated. As a result, among the plurality of gears constituting the transmission, the gear that is actually used is changed, or one of the above-described shift positions among a plurality of shift ranges set in advance in the transmission is supported. The shift range is changed.

  In the shift lever device according to the present invention, the shift lever is provided with an engaging member. The engagement member is movable between the engagement position and the engagement avoidance position, but is biased toward the engagement position by the first biasing means. As long as an external force exceeding the force does not act on the engaging member, the engaging member remains in the engaged position.

  When the shift lever thus provided with the engagement member tries to move to a specific shift position among the plurality of shift positions, or when the shift lever tries to move from the specific shift position. The engaging member located at the engaging position comes into contact with the interference avoiding means. The engaging member that moves together with the shift lever presses the interference avoiding unit from the unlocked position to the locked position by the contact of the interference avoiding unit.

  The interference avoiding means is biased toward the unlocking position by the second biasing means. The biasing force of the second biasing means is based on the biasing force of the first biasing means. It is smaller than the pressing force applied to. Therefore, basically, the interference avoiding means cannot resist the pressing force from the engaging member, moves from the unlocked position to the locked position, and the position of the engaging member is maintained at the engaged position. .

  If the shift lever further tries to move in this state, the engaging member receives interference by the interference means. Thus, when the engaging member receives interference from the interference means, the shift lever cannot move to the specific shift position or cannot move from the specific shift position (shift lock state). .

  On the other hand, the shift lever device according to the present invention includes an electromagnet. When the electromagnet is energized and a magnetic force is generated in the electromagnet, the interference avoiding means is attracted to the electromagnet. Here, the attracting force of the interference avoiding means by the electromagnet is larger than the pressing force that the interference avoiding means receives from the engaging member based on the biasing force of the first biasing means, with the resultant force with the biasing force of the second biasing means. It is set to be.

  As described above, when the shift lever is about to move to a specific shift position, or when the shift lever is about to move from a specific shift position, the engaging member comes into contact with the interference avoiding means, and interference avoidance is performed. The means receives a pressing force from the engaging member. However, when the electromagnet is energized as described above, the resultant force of the attraction force of the electromagnet and the urging force of the second urging means exceeds the pressing force from the engaging member based on the urging force of the first urging means. . For this reason, the interference avoiding means resists the pressing force from the engaging member, and does not move to the lock position.

  Since the interference avoiding means remains in the unlocked position, the engagement member that is in contact with the interference avoiding means tries to move together with the shift lever so that the interference avoiding means applies the biasing force of the first biasing means. Against the disengagement position. By moving the engagement member to the engagement release position, the engagement member does not receive interference from the restricting means, and the shift lever can move (shift lock release state).

  By the way, in the present shift lever device, as described above, the electromagnet does not move when the electromagnet constituting the shift lock device attracts the interference avoiding means by magnetic force or when the attracting is released. Therefore, the cord or the like for supplying current to the electromagnet at the time of energization or release of energization does not move.

  As a result, if the electromagnet is movable so far, the cord or the like has to be loosened according to the movable range of the electromagnet, but in the shift lock device of the shift lever device according to the present invention, the electromagnet It is not necessary to loosen the cord for feeding power, and the electromagnet can be fixed to the substrate or the like without using a flexible feeding member such as a cord.

  In addition, there is a possibility that the connection of the flexible power supply member such as the cord described above may be disconnected due to the movement of the electromagnet. However, in the shift lever device according to the present invention, the electromagnet does not move, and thus such a problem occurs. There is no. This improves the reliability of the shift lock device.

  As described above, in the shift lever device according to the present invention, since the electromagnet does not move, it is not necessary to bend and install the power feeding member for feeding power to the electromagnet, and the connection with the electromagnet is excessively strong. You don't have to.

<Configuration of First Embodiment>
FIG. 5 is an exploded perspective view schematically showing the overall configuration of the shift lever device 10 according to the first embodiment of the present invention.

  As shown in this figure, the shift lever device 10 includes a lower housing 12. The lower housing 12 includes a plurality of leg portions 14. For example, the leg portion 14 is fixed to a predetermined part of the vehicle body between the driver's seat and the passenger seat of the vehicle, so that the lower housing 12, and thus the shift lever, is provided. The device 10 is structured to be attached to a vehicle.

  An upper housing 16 is provided above the lower housing 12, and the upper housing 16 partitions the interior of the vehicle from a portion where the lower housing 12 and the like are provided. Further, the upper housing 16 is formed with a zigzag-shaped shift hole 18 that is appropriately bent in the vertical direction (for example, approximately the vehicle longitudinal direction) and the lateral direction (for example, approximately the vehicle width direction).

  In addition, the lower housing 12 includes a pair of side walls 20 that face each other along, for example, a substantially vehicle width direction (a substantially vehicle left-right direction). A circular hole 22 is coaxially formed in both side walls 20, and a shaft 24 is attached in a state of passing through the circular hole 22. A bracket 30 constituting a lever body 28 of the shift lever 26 is disposed between the side walls 20.

  The bracket 30 includes a cylindrical portion 32 having a substantially cylindrical shape that is axial along the opposing direction of the side walls 20. The above-described shaft 24 penetrates through the cylindrical portion 32, and the cylindrical portion 32, that is, the bracket 30 is pivotally supported by the shaft 24 so as to be rotatable about an axis whose axial direction is substantially the vehicle width direction.

  A holding portion 34 is provided integrally with the cylindrical portion 32 at an intermediate portion in the axial direction of the cylindrical portion 32. The holding portion 34 includes a pair of vertical walls 36 that face each other substantially in the vehicle front-rear direction with the cylindrical portion 32 supported by the shaft 24. In these vertical walls 36, circular holes 38 formed so as to penetrate along the opposing directions are formed coaxially, and a shaft 40 is disposed therethrough.

  Further, a block-shaped lever support portion 42 is disposed between the vertical walls 36. The lever support portion 42 is formed with a through hole 44 penetrating substantially in the vehicle front-rear direction, and the lever support portion 42 is rotated about an axis whose axis is substantially the vehicle front-rear direction with the shaft 40 penetrating therethrough. I support it as possible.

  Further, the lever support portion 42 is formed with an insertion hole 46 opened at the upper end thereof, and constitutes the lever main body 28 together with the lever support portion 42 and the bracket 30, and consequently the rod-like lever constituting the shift lever 26. The base end portion of the member 48 is fixed to the lever support portion 42 in a state where the member 48 is inserted. The lever member 48 protrudes above the upper housing 16 through the shift hole 18 of the upper housing 16.

  Further, a knob 50 that constitutes the shift lever 26 together with the lever member 48 is attached to the upper end portion of the lever member 48. When the lever 50 is gripped and pressed in the vehicle width direction, the lever member 48 is provided. Rotates around the shaft 40. Further, when the knob 50 is gripped and the lever member 48 is pressed substantially in the vehicle front-rear direction, the lever support portion 42 presses the vertical wall 36, whereby the bracket 30 rotates around the shaft 24. In this way, in the present shift lever device 10, the lever member 48, that is, the shift lever 26 is moved substantially in the vehicle front-rear direction by holding the knob 50 and pressing the lever member 48 in the substantially vehicle width direction or the vehicle front-rear direction. And it has the structure which rotates in the substantially vehicle width direction.

  Further, on the side of the shift hole 18 formed in the upper housing 16, marks such as letters representing a plurality of shift ranges set in the automatic transmission of the vehicle are described. The lower housing 12 is appropriately provided with a magnetic sensor such as a Hall element and an MRE element, and position detection means such as a microswitch, and the rotation position of the lever member 48 is detected by these position detection means. Based on the detection result of the lever member 48 by the position detection means, the ECU that controls the automatic transmission operates the automatic transmission to a shift range corresponding to the rotation position of the lever member 48.

  On the other hand, as shown in FIG. 3 and more specifically in FIG. 1, a plate guide 52 is formed in the lever support portion 42. The plate guide 52 includes a pair of guide walls 54 (only one guide wall 54 is shown in FIG. 1). These guide walls 54 extend from the side surface of the lever support portion 42 so as to face each other substantially along the vehicle front-rear direction.

  A main body 58 of a shift lock plate 56 as an engaging member constituting the shift lock device 55 is disposed between the guide walls 54. The main body 58 of the shift lock plate 56 is a plate-like member having a thickness direction along the axial direction of the lever member 48, and the base end side enters between the pair of guide walls 54 with respect to the middle portion in the longitudinal direction. The guide wall 54 is slidably held only in the axial direction of the lever member 48.

  A pressing piece 60 is further extended from the longitudinal end portion of the main body 58 of the shift lock plate 56. The pressing piece 60 has a width dimension shorter than the width dimension of the main body 58, and is formed on the front end side of the main body 58 with respect to the intermediate portion in the width direction at the front end portion of the main body 58.

  A locking piece 62 is formed above the pair of guide walls 54. One end of a compression coil spring 64 as a first urging means is locked to the lower end surface of the locking piece 62. The other end of the compression coil spring 64 is fixed to the upper end face of the shift lock plate 56. The compression coil spring 64 mechanically connects the locking piece 62 and the shift lock plate 56, and shifts. The lock plate 56 is urged downward.

  On the other hand, a guide hole 66 is formed in one of the pair of side walls 20 constituting the lower housing 12. The guide hole 66 is formed corresponding to the shift lock plate 56. Basically, when the lever member 48 rotates in a direction approaching the one side wall 20, the pressing piece 60 and the main body are formed in the guide hole 66. It is formed so that the front end side of 58 can enter.

  However, as shown in FIG. 1, a regulation wall 68 as a regulation means extends upward from an inner peripheral portion on the front end side of the guide hole 66. The restriction wall 68 is a P position (a shift position of the lever member 48 corresponding to the parking range used for locking the wheels when the vehicle is stopped among the plurality of shift ranges set in the automatic transmission (see “ The compression coil spring 64 is provided opposite to the main body 58 of the shift lock plate 56 in a state in which the lever member 48 is positioned on the side of the mark “P” and in the natural length state.

  Accordingly, when the lever member 48 is rotated from the P position to the side of the one side wall 20 in order to move the lever member 48 from the P position to another shift position, the main body of the shift lock plate 56 is placed on the restriction wall 68. 58 is in contact with the lever member 48 so as to restrict the detachment of the lever member 48 from the P position.

  A solenoid mounting hole 70 is formed continuously at the front end of the guide hole 66. Inside the solenoid mounting hole 70, a cam member 72 is provided as interference avoiding means. The cam member 72 includes a base 74 formed in a plate shape from a magnetic material such as metal.

  A compression coil spring 76 is provided between the base 74 and the inner peripheral portion on the lower side of the solenoid mounting hole 70 as second biasing means having a sufficiently smaller biasing force than the compression coil spring 76 described above. The base 74 is urged upward. A substantially block-shaped main body 78 is formed on one end in the longitudinal direction on the upper surface of the base 74. A slope 80 inclined upward with respect to the side of the other side wall 20 is formed at the tip of the main body 78.

  The inclined surface 80 is opposed to the pressing piece 60 in a state where the lever member 48 is positioned at the P position in a state where no external force against each urging force is applied to any of the compression coil springs 64 and 76. When the lever member 48 formed at the P position is rotated toward the one side wall 20 so as to be separated from the P position, the pressing piece 60 comes into contact with the inclined surface 80.

  A solenoid 82 as an electromagnet is fixed to the side wall 20 on the side of the main body 58. The solenoid 82 is configured to generate a magnetic force when energized, and the base 74 that is in pressure contact with the solenoid 82 by the urging force of the compression coil spring 76 causes the solenoid 82 to generate a magnetic force generated by energizing the solenoid 82. To be adsorbed. Here, the attracting force when the energized solenoid 82 attracts the base 74 is such that the resultant force with the second biasing force of the compression coil spring 76 exceeds the magnitude of the first biasing force of the compression coil spring 64. Is set.

<Operation and Effect of First Embodiment>
Next, the operation and effect of the present embodiment will be described.

  In the present shift lever device 10, for example, when an occupant seated in the driver's seat of the vehicle grips the knob 50 and presses the lever member 48 in a substantially vehicle width direction or a vehicle front-rear direction according to the shape of the shift hole 18, Along the 48 shift holes 18, the shafts 24 and 40 rotate. Further, the rotation position of the lever member 48 that rotates along the shift hole 18 is detected by the position detecting means provided appropriately in the lower housing 12, and the mark is formed on the upper housing 16. When the position detecting means detects that the lever member 48 is located, the ECU for controlling the automatic transmission operates and controls the automatic transmission, and the shift range corresponding to the mark on the side of the lever member 48 is detected. Change to

  On the other hand, in a state where the lever member 48 as shown in FIG. 2 is located at the P position, the lever member 48 is rotated from the P position toward the side wall 20 in order to change to a shift range other than the parking range. When trying to do so, the pressing piece 60 approaches and comes into contact with the inclined surface 80 of the cam member 72.

  Here, since the first urging force of the compression coil spring 64 is larger than the second urging force of the compression coil spring 76, when the lever member 48 is moved toward the one side wall 20 as shown in FIG. The pressing piece 60 presses the inclined surface 80 and lowers the cam member 72 against the second urging force of the compression coil spring 76. In this state, basically, an external force that can overcome the first urging force of the compression coil spring 64 does not act on the compression coil spring 64. Therefore, the regulating wall 68 and the shift lock plate along the rotation direction of the lever member 48. 56 main bodies 58 face each other.

  Accordingly, when the lever main body 28 is rotated toward the one side wall 20, as shown in FIG. 3, the main body 58 of the shift lock plate 56 contacts the restriction wall 68, and the main body 58 enters the guide hole 66. I can't. Thus, since the lever member 48 cannot be rotated until the main body 58 enters the guide hole 66, the lever member 48 cannot be removed from the P position, and the shift range of the automatic transmission is the parking range. It is maintained as it is (shift lock state).

  On the other hand, for example, when an occupant in the driver's seat steps on a brake pedal that constitutes a foot brake of the vehicle while the lever member 48 is in the P position, the solenoid 82 is energized and a magnetic force is generated in the solenoid 82. Thus, when a magnetic force is generated in the solenoid 82, the base portion 74 of the cam member 72 is attracted to the solenoid 82 by this magnetic force.

  Next, in this state, when the lever member 48 is rotated to the side of the one side wall 20 in order to disengage the lever member 48 from the P position, the pressing piece 60 comes into contact with the inclined surface 80 as described above. However, in this state, a magnetic force is generated in the solenoid 82. As described above, the resultant force of the adsorbing force of the solenoid 82 on the base 74 based on the magnetic force of the solenoid 82 and the second urging force of the compression coil spring 76 is the compression coil. It is larger than the first biasing force of the spring 64.

  For this reason, even if the pressing piece 60 presses the inclined surface 80 in this state, the shift lock plate 56 biased by the first biasing force of the compression coil spring 64 causes the suction force of the solenoid 82 and the second force of the compression coil spring 76 to move. The cam member 72 cannot be pushed down against the urging force. Therefore, as shown in FIG. 4, when the lever member 48 is rotated toward the side wall 20 in this state, the shift lock plate 56 is guided against the first urging force of the compression coil spring 64. While being guided by the wall 54, it slides upward, that is, toward the distal end side of the lever member 48.

  Thus, as the shift lock plate 56 slides upward, as shown in FIG. 4, the main body 58 of the shift lock plate 56 is positioned above the front end of the regulating wall 68, and the main body of the shift lock plate 56. 58 can enter the guide hole 66 without coming into contact with the regulating wall 68 (shift lock released state).

  Therefore, the lever member 48 can be detached from the P position by rotating the lever member 48 toward the one side wall 20 until the main body 58 of the shift lock plate 56 enters the guide hole 66, and the shift range is different from the parking range. The shift lever 26 can be rotated to the shift position corresponding to the above.

  As described above, in the present shift lever device 10, the lever member 48 cannot be detached from the P position unless the predetermined condition such as depressing the brake pedal as described above is satisfied. It is possible to prevent the automatic transmission from being changed to a shift range different from the parking range.

  Incidentally, as described above, in the present shift lever device 10, the solenoid 82 is fixed to the side wall 20 and does not move together with the cam member 72. For this reason, even if the lever member 48 is rotated, a cord or the like for causing a current to flow through the solenoid 82 does not move. Therefore, the cord for feeding power to the solenoid 82 does not need to be loosened, and the electromagnet can be fixed to the substrate or the like without using a flexible feeding member such as a cord.

  Further, since the solenoid 82 does not move, the connection of a flexible power supply member such as a cord is not disconnected. Thereby, the reliability of the shift lock device 55 of the present shift lever device 10 is improved.

  Further, in this shift lever device 10, a shift lock plate 56 is provided on the side surface of the lever support portion 42, and the shift lock device 56 is shift-locked to the regulation wall 68 along the rotation direction of the lever member 48 toward the side wall 20. When the main body 58 of the plate 56 abuts, the rotation of the lever member 48 toward the side wall 20 is restricted. Therefore, no matter how much the lever member 48 is rotated toward the one side wall 20 with an excessive force, the contact between the regulation wall 68 and the main body 58 of the shift lock plate 56 is not released. For this reason, the lever member 48 is operated with an excessive force, so that the so-called “unlocking” that inadvertently releases the locked state does not occur in the shift lever device 10. The reliability of the device 55 can be improved.

<Configuration of Second Embodiment>
Next, a second embodiment of the present invention will be described. In the following description of the second embodiment, components that are basically the same as those in the first embodiment are given the same reference numerals, and detailed descriptions thereof are omitted.

  FIG. 6 is a front view schematically showing the configuration of the main part of the shift lever device 110 according to the present embodiment.

  As shown in this figure, the lever support portion 42 constituting the shift lever device 110 is not formed with the guide wall 54 or the locking piece 62, and is not provided with the shift lock plate 56. Instead, the shaft 112 is formed so as to protrude from the end surface of the lever support portion 42 on the substantially vehicle front side.

  A base portion 118 of a shift lock plate 116 as an engaging member constituting the shift lock device 114 is supported on the shaft 112 so as to be rotatable around an axis having a substantially vehicle longitudinal direction as an axial direction. Further, one end of a torsion coil spring 120 as a first urging means is locked to the shaft 112. The other end of the torsion coil spring 120 is locked to the base 118 of the shift lock plate 116, and the torsion coil spring 120 biases the shift lock plate 116 in the direction of arrow A in FIG.

  On the other hand, a regulation hole 122 whose inner periphery is a regulation means is formed in one of the pair of side walls 20. The restriction hole 122 is formed corresponding to the shift lock plate 116 in a state where the lever member 48 is located at the P position, and the lever member 48 is formed on one side wall 20 when the lever member 48 is located at the P position. When it is pivoted in the direction in which it approaches, the insertion piece 124 formed at the tip of the shift lock plate 116 is formed so as to enter the inside of the restriction hole 122.

  In addition, a shaft 126 that is axially formed substantially along the vehicle front-rear direction is formed on the inner peripheral portion of the restriction hole 122, and a guide plate 128 as an interference avoiding means formed of a magnetic material such as metal is provided. The shaft 126 is rotatably supported around the shaft 126. Further, one end of a torsion coil spring 130 as a second urging means is locked to the shaft 126.

  The other end of the torsion coil spring 130 is locked to the guide plate 128, and the guide plate 128 is moved in the direction of arrow B in FIG. 6 with a second biasing force that is weaker than the first biasing force of the torsion coil spring 120. Energized.

  Further, the guide plate 128 is disposed in a state of penetrating the restriction hole 122. A cam piece 132 is formed on the shift lock plate 116 corresponding to the tip of the guide plate 128.

  The cam piece 132 is formed on the base 118 side of the insertion piece 124 and on the upper side of the insertion piece 124. In addition, the cam piece 132 has a slope 134. The inclined surface 134 is inclined upward with respect to the side wall 20, and the lower side of the intermediate portion in the vertical direction faces the tip of the guide plate 128 with the lever member 48 positioned at the P position. Yes.

  Further, the base end of the guide plate 128 protrudes to the back side of the one side wall 20. A solenoid 82 is fixed to the back surface of one side wall 20 facing the base end of the guide plate 128. Here, the attracting force when the solenoid 82 attracts the base portion of the guide plate 128 based on the magnetic force generated by energizing the solenoid 82 is the resultant force with the second biasing force of the torsion coil spring 130. It is set to exceed the magnitude of the first urging force of the torsion coil spring 120.

<Operation and Effect of Second Embodiment>
Next, the operation and effect of the present embodiment will be described.

  In the present shift lever device 110, when the lever member 48 is rotated from the P position toward the one side wall 20 in order to change to a shift range other than the parking range with the lever member 48 positioned at the P position, The slope 134 of the shift lock plate 116 approaches and abuts the tip of the guide plate 128.

  Here, since the first urging force of the torsion coil spring 120 is larger than the second urging force of the torsion coil spring 130, when the lever member 48 is moved toward the side wall 20, the inclined surface 134 is guided. The front end portion of the plate 128 is pressed, and the front end portion of the guide plate 128 is rotated upward against the second urging force of the torsion coil spring 130.

  In this state, basically, an external force that can overcome the first biasing force of the torsion coil spring 120 does not act on the torsion coil spring 120. For this reason, when the lever member 48 rotates toward the one side wall 20, the insertion piece 124 of the shift lock plate 116 enters the restriction hole 122 as shown in FIG. 7.

  In this state, in order to move the shift lever 26 to a shift position corresponding to a shift range different from the parking range, if the lever member 48 is rotated substantially toward the rear side of the vehicle, the inner periphery of the restriction hole 122 The insertion piece 124 abuts, and the movement of the insertion piece 124 to the rear side of the vehicle and the rotation of the lever member 48 to the rear side of the vehicle are restricted by the inner peripheral portion of the restriction hole 122 (shift lock). Status).

  Therefore, in this state, the shift lever 26 cannot be rotated to a shift position corresponding to a shift range different from the parking range. For this reason, the shift range of the automatic transmission is maintained in the parking range.

  On the other hand, for example, when an occupant in the driver's seat steps on a brake pedal that constitutes a foot brake of the vehicle while the lever member 48 is in the P position, the solenoid 82 is energized and a magnetic force is generated in the solenoid 82. Thus, when a magnetic force is generated in the solenoid 82, the base portion of the guide plate 128 is attracted to the solenoid 82 by this magnetic force.

  Next, in this state, when the lever member 48 is rotated to the side of the one side wall 20 in order to disengage the lever member 48 from the P position, the inclined surface 134 contacts the tip of the guide plate 128 as described above. Touch. However, in this state, a magnetic force is generated in the solenoid 82, and the resultant force of the attracting force of the solenoid 82 based on the magnetic force of the solenoid 82 and the second urging force of the torsion coil spring 130 is twisted as described above. It is larger than the first urging force of the coil spring 120. For this reason, even if the inclined surface 134 presses the tip of the guide plate 128 in this state, the shift lock plate 116 urged by the first urging force of the torsion coil spring 120 causes the adsorption force of the solenoid 82 and the compression coil to be compressed. The tip of the guide plate 128 cannot be rotated upward against the second urging force of the spring 76.

  Therefore, when the lever member 48 is rotated toward the side wall 20 in this state, the guide plate 128 in which the resultant force of the second urging force of the torsion coil spring 130 and the attracting force of the solenoid 82 acts is shown in FIG. As shown in FIG. 8, the shift lock plate 116 is rotated downward by a pressing reaction force corresponding to the pressing force from the inclined surface 134 against the first biasing force of the torsion coil spring 120 ( Shift lock released state).

  In this way, the shift lock plate 116 is rotated downward, so that, as shown in FIG. 8, even if the lever member 48 rotates toward the one side wall 20, the insertion piece 124 enters the restriction hole 122. Don't get in. Therefore, even if the lever member 48 is rotated to the rear side of the vehicle in this state, the insertion piece 124 does not receive interference from the inner peripheral portion of the restriction hole 122, and the lever member 48 is rotated to the rear side of the vehicle. I can move.

  As described above, in the present shift lever device 110, the lever member 48 is rotated to the shift position corresponding to the shift range other than the parking range unless the predetermined condition such as depressing the brake pedal as described above is satisfied. Therefore, it is possible to prevent the automatic transmission from being carelessly changed to a shift range different from the parking range when the vehicle is stopped.

  Further, as described above, in the shift lever device 110, the solenoid 82 is fixed to the back surface of the side wall 20, and does not move (turn) with the guide plate 128 or the like. For this reason, even if the lever member 48 is rotated, a cord or the like for causing a current to flow through the solenoid 82 does not move. Therefore, the cord for feeding power to the solenoid 82 does not need to be loosened, and the electromagnet can be fixed to the substrate or the like without using a flexible feeding member such as a cord.

  Further, since the solenoid 82 does not move, the connection of a flexible power supply member such as a cord is not disconnected. The reliability of the shift lock device 114 is improved.
