Thereby, the sliding member 85 pressed by the lever shaft 41 returns to the original position on the right side of the pressed operation portion 81h shown in FIG. 8 when the pressing is lost.

  Further, the right end side of the second pressing operation member main body 86 is placed in the casing 10, and as shown in FIG. 17, the pressing operation portion 85b of the sliding member 85 is pressed operation portion of the plus gate detection switch operation arm 81e. A range from the upper position of 81h to the upper position (not shown) of the pressed operation portion 81h of the negative gate detection switch operation arm 81d is movable in the front-rear direction.

  Further, as shown in FIG. 6, the second pressing operation member main body 86 pressed by the lever shaft 41 is urged by the second urging means, and when the pressing from the lever shaft 41 is eliminated. The original position shown in FIG. 8 is returned.

  Specifically, the second pressing operation member main body 86 is provided with second urging means on the upper side thereof. The second urging means of this embodiment includes a protruding piece holding portion 89 fixed to the second pressing operation member main body 86 and a pair of front and rear protruding pieces held by the protruding piece holding portion 89 so as to be slidable in the front-rear direction. 88 and a second coil spring 87b disposed between the projecting pieces 88.

  Although not shown, each of the projecting pieces 88 is disposed in the casing 10 so as to contact the inner wall of the casing 10.

  When the second pressing operation member main body 86 is pressed by the lever shaft 41 and moves forward or rearward, the projecting piece 88 abutting against the inner wall of the casing 10 is rearward or forward of the projecting piece holding portion 89. Move relative to the direction.

  During the relative movement, the second coil spring 87b is compressed, whereby the second pressing operation member main body 86 is urged rearward or forward.

  Note that the holding piece 86 a of the second pressing operation member main body 86 and the sliding member lever pressing portion 85 a of the sliding member 85 protrude outward from the left end of the casing 10 and are arranged below the communication path 55 of the gate plate 51. As shown in FIG. 16, when the lever shaft 41 enters the communication path 55, the lever shaft 41 can enter between the holding pieces 86a to press the sliding member lever pressing portion 85a of the sliding member 85. It is like that.

  Next, the shift lock mechanism will be described. This shift lock mechanism shift-locks (locks) when the lever shaft 41 of the change lever 4 enters the parking range 53a so that the lever shaft 41 of the change lever 4 does not unexpectedly move to the other ranges 53b to 53d. Is for.

  As shown in FIGS. 3 and 4, the shift lock mechanism of this embodiment can be interlocked with a lock member 90 that is detachably engaged with the transmission switching member 3 and a brake pedal as a brake device provided in the vehicle. And a locking arm 94 that is detachably locked to the solenoid 100.

  The lock member 90 includes a lock shaft 91 and a long lock shaft operation member 92 that moves the lock shaft 91 in a movable manner.

  The lock shaft 91 is housed in the lock shaft housing hole 21 (see FIG. 2) of the apparatus main body 2 so as to be movable in the axial direction, and as shown in FIG. When moving to the side), the lock member 37 enters the lock hole 37a of the switching member main body 30. Thereby, the switching member main body 30 that has entered the switching member receiving groove 22 of the apparatus main body 2 is locked.

  The lock shaft 91 housed in the lock shaft housing hole 21 is urged to the right side (the other direction side) in the axial direction by a coil spring 21b as an urging member provided in the lock shaft housing hole 21, The urging force causes the lock shaft 91 that has entered the lock hole 37a to come out of the lock hole 37a.

  The lock shaft operating member 92 has a longitudinal upper end side (one end side) thereof rotatably connected to the first pressing operation member 83 in the casing 10, and the first pressing operation member 83 is connected to the change lever 4. When the first pressing operation member 83 is moved by being pressed by the lever shaft 41, the upper end side of the lock shaft operation member 92 is moved along with the movement. Therefore, in this embodiment, the lock shaft operating member 92 is indirectly pressed against the lever shaft 41 of the change lever 4 via the first pressing operation member 83.

  Further, the intermediate portion 92a in the longitudinal direction of the lock shaft operating member 92 is pivotally supported by the casing 10 in the casing 10, so that the upper end side and the lower end side (the other end side) are centered on the intermediate portion 92a. And can be rotated in the left-right direction.

  Further, as shown in FIG. 5, a U-shaped locking groove 92b opened from the lower end surface is provided at the lower end of the lock shaft operating member 92. The lower end side of the lock shaft operating member 92 is extended to the outside from the lower end of the casing 10 as shown in FIG. 1. When the casing 10 is attached to the right side wall 52 b, the lock shaft operating member 92 is provided with a locking shaft 91. A pin 91a (shown in FIGS. 1 and 4) is inserted into the locking groove 92b. Thereby, the lower end of the lock shaft operating member 92 and the lock shaft 91 are rotatably connected.

  The locking arm 94 is interlocked with the lock member 90 and moves within a certain range when the lock member 90 and the switching member main body 30 are engaged and disengaged.

  In this embodiment, the locking arm 94 is integrally extended downward from the first pressing operation member 83, as shown in FIGS. 3 and 4, and the locking member is interposed via the first pressing operation member 83. It moves in the left-right direction in conjunction with 90 lock shaft operating members 92.

  The solenoid 100 includes a solenoid main body 101 having a coil wire (not shown) therein, and a rod-like plunger 102 protruding from the solenoid main body 101.

  The plunger 102 is disposed so as to be movable in and out (movable in the axial direction) from the solenoid body 101. Further, the plunger 102 of this embodiment is always urged in a direction protruding from the solenoid body 101 by a biasing spring (not shown) provided in the solenoid body 101. When a magnetic force is generated due to energization of the coil wire, the solenoid body 101 is immersed (sucked) against the biasing force of the biasing spring.

  Therefore, the plunger 102 of this embodiment moves from the longest state (the state shown in FIG. 4) in which the protrusion length from the solenoid main body 101 is projected and moved relative to the solenoid main body 101 to the solenoid main body 101. The range from the solenoid body 101 to the shortest state (state shown in FIG. 10) where the protrusion length from the solenoid body 101 is the shortest is movable with respect to the solenoid body 101.

  The solenoid 100 is communicably connected to the key interlock detection switch 71a and the parking detection switch 71b via the control main body of the vehicle. Specifically, the control body of the vehicle that is communicably connected to the key interlock detection switch 71a and the parking detection switch 71b and the solenoid 100 are communicably connected.

  The solenoid 100 is controlled by the control main body so as to be interlocked with the brake pedal. More specifically, when the control body detects that the lever shaft 41 of the change lever 4 has entered the parking range 53a by the parking detection switch 71b, when the brake pedal is depressed, the control body The solenoid 100 is energized based on the detection. And with the energization, the plunger 102 is immersed in the solenoid main body 101.

  In the solenoid 100 configured in this manner, the solenoid body 101 is housed in the casing 10 and fixed. In this stored state, the axial direction of the plunger 102 is along the front-rear direction and is orthogonal to the moving direction of the locking arm 94. Further, as shown in FIG. 10, the plunger 102 is in the shortest state in which it is retracted, and is located outside the path retracted from the movable path in which the locking arm 94 moves. 2. As shown in FIG. 4, it is disposed so as to have a position in the path that has entered the path across the movable path.

  Next, the operation of the shift device 1 will be described. For convenience of explanation, the lever shaft 41 of the change lever 4 will be described from the state where it is not in the parking range 53a of the main gate 53, for example, the left side of the parking range 53a.

  When the lever shaft 41 is on the left side position of the parking range 53a, as shown in FIGS. 7 and 8, the first pressing operation member 83 is separated from the lever shaft 41, and the key interlock switch operation arm. 81a and the parking detection switch operation arm 81b are arranged on the left side of the pressed operation portion 81h.

  Further, as shown in FIG. 9, the locking arm 94 closes the front side of the plunger 102 of the solenoid 100, and the distal end surface of the plunger 102 that tries to protrude by the urging force of the urging spring is locked. The arm 94 is in contact with the rear surface. The lock portion 37 of the switching member main body 30 enters the switching member receiving groove 22 of the apparatus main body 2, and the lock hole 37 a of the lock portion 37 and the lock shaft accommodation hole 21 of the apparatus main body 2 are in agreement. (See FIG. 2).

  When the lever shaft 41 enters the parking range 53a from this state, the lever shaft 41 contacts the lever pressing portion 83a of the first pressing operation member 83 as shown in FIG.

  Furthermore, when the lever shaft 41 enters the parking range 53a, the lever pressing portion 83a is pressed and the first pressing operation member 83 moves to the right (see FIG. 12). Further, when the first pressing operation member 83 is moved, the locking arm 94 is also moved to the right side to the right position of the plunger 102 of the solenoid 100 (see FIG. 3).

  At the same time, the lock shaft operating member 92 rotates counterclockwise in FIG. 3, and the lock shaft 91 is moved to the right in FIG. 3 against the urging force of the coil spring 21b. As a result, the lock shaft 91 enters the lock hole 37a of the switching member main body 30 to place the switching member main body 30 in the locked state.

  When the locking arm 94 passes through the plunger 102 of the solenoid 100, the plunger 102 that is in contact with the locking arm 94 is moved by the biasing force of the biasing spring as shown in FIG. The longest state is reached by projecting to the position in the path across the movable path.

  Further, when the first pressing operation member 83 is moved, as shown in FIG. 13, the pressing operation portion 83b starts to press the pressed operation portion 81h of the parking detection switch operation arm 81b and the key interlock switch operation. The pressing operation portion 81h of the arm 81a is pressed.

  By this pressing operation, the switch pressing portions 81g of the parking detection switch operating arm 81b and the key interlock switch operating arm 81a press the pressing buttons 72f of the parking detection switch 71b and the key interlock detection switch 71a, respectively.

  At that time, the key interlock switch operating arm 81a has elasticity and can be bent in the longitudinal direction as shown in FIG. Accordingly, even if the pressed operation portion 81h is pressed with an excessive force, the pressing button 72f can be prevented from being pressed with the excessive force, and the detection switches 71a and 71b can be prevented from being overloaded. On the other hand, the push button 72f can be reliably pressed by elasticity, and each detection switch 71a, 71b can be operated reliably.

  When the parking detection switch 71b is pressed, information to that effect is transmitted to the control main body of the vehicle. The received control main body waits for the brake pedal to be depressed, and energizes the solenoid 100 when the brake pedal is depressed as will be described later.

  When the key interlock detection switch 71a is pressed, information to that effect is transmitted to the vehicle control body, and the received control body receives the key that has entered the key insertion hole provided in the vehicle. Make the key insertion hole ready for removal.

  In this state, the lock shaft 91, the lock shaft operating member 92, the locking arm 94, and the first pressing operation member 83 each move in the opposite direction by the biasing force of the coil spring 21b.

  However, since the plunger 102 is located at the position in the path of the locking arm 94, the locking arm 94 is locked to the plunger 102 to maintain the position as shown in FIG. The operation member 92 and the first pressing operation member 83 also maintain their positions. Therefore, the switching member main body 30 is maintained in the locked state.

  In this state, the lever shaft 41 connected to the switching member main body 30 cannot move in the front-rear direction. Therefore, for example, even if the lever shaft 41 is erroneously moved while the vehicle is stopped, the lever shaft 41 maintains the position of the parking range 53a and can be prevented from moving from the parking range 53a to the reverse range 53b.

  When the lever shaft 41 enters the parking range 53a, the lever shaft 41 of the change lever 4 is moved to the parking range 53a by a locking means (not shown) for detachably locking the change lever 4 and the gate member 5. You can maintain the state that entered.

  To release the locked state and drive the vehicle, step on the brake pedal. As a result, the control main body that has detected it energizes the solenoid main body 101 via the circuit board 72. Then, as shown in FIG. 10, due to the generation of the magnetic force due to the energization, the plunger 102 moves into the position outside the path of the locking arm 94 against the urging force of the urging spring and becomes the shortest state.

  As a result, the locking between the locking arm 94 and the plunger 102 is released. As a result of the release of the engagement, the engagement arm 94, the lock shaft 91, the lock shaft operation member 92, and the first pressing operation member 83 are moved in the opposite direction by the urging force of the coil spring 21b.

  Then, as shown in FIGS. 7 and 9, the locking arm 94 moves to the front position of the plunger 102 and closes the front of the plunger 102. In this state, when the stepping operation of the brake pedal is stopped, the control main body unit that detects the operation stops supplying power to the solenoid 100.

  As a result, the plunger 102 of the solenoid 100 projects by the urging force of the urging spring, abuts against the rear surface of the locking arm 94, and maintains that state.

  Further, with the movement of the first pressing operation member 83, the parking detection switch 71b that has been pressed is released and the pressing operation is stopped.

  When the parking detection switch 71b is no longer pressed, information to that effect is transmitted to the control body, and the control body is based on that information (or no longer receives the pressed information). The solenoid 100 is controlled not to be energized when the brake pedal is subsequently depressed.

  Therefore, the control main body of this embodiment is in the state where the parking detection switch 71b detects that the change lever 4 has entered the parking range 53a as described above (while the parking detection switch 71b is on). When the brake pedal is depressed, the solenoid 100 is energized, and control is performed so that the solenoid 100 is not energized even when the brake pedal is depressed while the parking detection switch 71b is OFF.

  As the first pressing operation member 83 moves, the key interlock detection switch 71a is not pressed before the parking detection switch 71b is not pressed. Then, the information to that effect is transmitted to the control main body, and the received control main body receives the key from the key insertion hole and the vehicle based on the information (or no longer receives the pressed information). Is controlled so as not to be removed by means of a key removal prevention means (not shown) provided in FIG.

  Thereafter, the lever shaft 41 of the change lever 4 is taken out of the parking range 53a, and when it is operated to move to the reverse range 53b, neutral range 53c, or drive range 53d along the main gate 53, it is connected to the change lever 4. The switching member main body 30 rotates forward.

  Further, when the switching member main body 30 is rotated, the cable 10 (shown in FIG. 1) is pushed and pulled to switch the automatic transmission.

  Further, when the lever shaft 41 enters the communication path 55 (see FIG. 2) from the drive range 53d, the lever shaft 41 comes into contact with the sliding member lever pressing portion 85a of the sliding member 85 of the second pressing operation member 84 (see FIG. 2). (See FIG. 16).

  In this state, when the lever shaft 41 moves further through the communication passage 55 to the right side sub-gate 54 side, as shown in FIG. The detection switch operation arm 81d and the positive gate detection switch operation arm 81e move to the right side until they are positioned to the right of the pressed operation portion 81h. During the movement, the pressed operation portion 81h of the communication path detection switch operating arm 81c is pressed.

  In accordance with this pressing operation, the switch pressing portion 81g of the communication path detection switch operation arm 81c presses the pressing button 72f of the communication path detection switch 71c.

  Also in this case, since the communication path detection switch operation arm 81c has elasticity, it can be bent in the longitudinal direction as shown in FIG. 14, and the key interlock switch operation arm 81a and the parking detection switch operation can be operated. It functions similarly to the arm 81b.

  The pressed communication path detection switch 71c transmits information indicating that the communication path has been pressed to the control main body. The received control main body unit switches from the auto mode state to the manual mode state.

  Further, when the lever shaft 41 is in the sub-gate 54, the connecting piece 43 of the change lever 4 comes out of the connecting hole 32 of the switching member main body 30 as shown in FIG. The connection with 30 is released.

  Therefore, in this disengaged state, the change lever 4 and the switching member main body 30 are not interlocked, and the automatic transmission is maintained in the drive state even if the lever shaft 41 of the change lever 4 moves the sub-gate 54 in the front-rear direction. The

  When the lever shaft 41 that has entered the sub-gate 54 is inserted into the plus gate 54b, for example, as shown in FIG. 17, when the lever shaft 41 enters the plus gate 54b, the lever for the main body of the second pressing operation member main body 86 is obtained. The pressing portion 86c is pressed rearward.

  During the pressing, the second pressing operation member main body 86 and the sliding member 85 held by the second movement member 85 are moved rearward, and the pressing operation portion 85b of the sliding member 85 is operated by the pressed operation portion 81h of the plus gate detection switch operation arm 81e. Is pressed.

  Further, along with this pressing operation, the switch pressing portion 81g of the operating arm 81e for the plus gate detection switch presses the pressing button 72f of the plus gate detection switch 71e.

  Also in this case, the plus gate detection switch operation arm 81e has elasticity, and thus functions in the same manner as the key interlock switch operation arm 81a and the like.

  Then, the pressed plus gate detection switch 71e transmits information indicating that it has been pressed to the control main body. The received control main body shifts up only once based on the information.

  When the lever shaft 41 that has entered the plus gate 54b is returned to the original position, the hand that pushes the lever shaft 41 in is operated. Accordingly, the second pressing operation member 84 returns to the original position by the urging force of the second coil spring 87b (see FIG. 6), and accordingly, the lever shaft 41 moves between the plus gate 54b and the minus gate 54a in the sub gate 54. Return to the intermediate position (position shown in FIG. 16).

  On the other hand, when the lever shaft 41 is inserted into the minus gate 54a, the main body lever pressing portion 86c of the second pressing operation member main body 86 is pressed forward when the lever shaft 41 enters the minus gate 54a.

  During the pressing, the second pressing operation member main body 86 and the sliding member 85 held thereby move forward, and the pressing operation portion 85b of the sliding member 85 moves to the pressed operation portion 81h of the minus gate detection switch operation arm 81d. Is pressed.

  In accordance with this pressing operation, the switch pressing portion 81g of the negative gate detection switch operation arm 81d presses the pressing button 72f of the negative gate detection switch 71d.

  Then, the pressed minus gate detection switch 71d transmits information indicating that it has been pressed to the control main body. The received control main body shifts down only once based on the information.

  Further, when the hand is released from the lever shaft 41 entering the minus gate 54a, the second pressing operation member 84 returns to the original position by the urging force of the second coil spring 87b (see FIG. 6), and accordingly, the lever shaft 41 However, it returns to an intermediate position (position shown in FIG. 16) between the plus gate 54b and the minus gate 54a in the sub-gate 54.

  Thereafter, when the lever shaft 41 of the change lever 4 is returned from the sub-gate 54 through the communication path 55 to the drive range 53d, the connection piece 43 of the change lever 4 enters the connection hole 32 of the switching member body 30 again. The change lever 4 and the switching member main body 30 are connected again.

  When the lever shaft 41 of the change lever 4 is moved from the drive range 84 of the main gate 53 to the neutral range 53c, the switching member main body 30 connected to the change lever 4 rotates to the front side opposite to the above. To do.

  In the above-described embodiment, the solenoid body 101 is housed in the casing 10. However, the invention is not limited to this. For example, the solenoid body 101 may be attached to the apparatus body 2 separately from the casing 10. Can be changed as appropriate.
