When the lever welded to the shift lever 40 comes into contact with a contact of a micro switch (not shown), the solenoid 10 is in an excited state, that is, in an ON state, and the plunger 12 is attracted to reverse the lock lever 70. The lock portion 72 is set so as to be rotated clockwise so as to move to a position facing the position pin 21 when the lock portion 72 is at the parking position P.

When the brake pedal is depressed when the vehicle starts, the solenoid 10 is in the non-excited state, that is, the OFF state, the plunger 12 projects in the direction of arrow A (see FIG. 3) by the spring force of the compression spring, and the lock lever 70 is released.

Since the key lock cable 81 is pulled by the key lock lever 50, the stopper 84 is moved downward to a position where the key rotor 83 is allowed to rotate.

Further, as shown in FIG. 4, the key rotor 83 is provided with a restricting portion 83a for restricting the counterclockwise rotation of the key rotor 83 when the key rotor 83 is rotated to a position other than the lock position LOCK. Has been. Reference numeral 83b is a position restricting portion of the stopper 84 formed on the key rotor 83.

Next, the operation of the first embodiment of the present invention will be described.

When attaching the solenoid 10 to the solenoid case 20, the solenoid 10 is inserted into the opening 20 a of the solenoid case 20 in the direction of arrow B (see FIG. 3). Then, the plate 13 and the inclined portion 11c of the solenoid 10 come into contact with the lead surfaces 21a and 22a of the engaging claws 21 and 22 of the solenoid case 20 to bend the engaging claws 21 and 22 outward.

Then, as shown in FIG. 1, when the solenoid 10 reaches a predetermined position, the engaging portions 21b and 22b of the engaging claws 21 and 22 come into contact with the end surface of the plate 13 and the inclined portion 11c, and the solenoid 10 can be elastically supported by the engaging claws 21 and 22. At the same time, the wall surface 11b of the solenoid 10 is pressed by the convex portion 26 toward the non-engaging side. Thereby, the main body 11 of the solenoid 10 can be firmly supported.

As described above, when the bracket 23 integral with the solenoid case 20 accommodating the solenoid 10 is attached to the machine frame 32, the bead 22c of the engaging claw 22 comes into contact with the reinforcing member 33. As a result, the engagement claw 22 can be prevented from being deformed toward the non-engagement side, and the main body 11 of the solenoid 10 can be supported more firmly. As a result, it is possible to prevent the solenoid 10 from falling off and to prevent rattling due to vibration or the like.

Next, the operation of the shift lever device F of the vehicle automatic transmission to which the solenoid mounting structure E according to the present invention is applied will be described.

As shown in FIG. 2, when the shift lever 40 is shifted to the parking position P and the engine key is removed from the cylinder lock 80 during parking, the arm portions 50 a and 60 a of the key lock lever 50 and the support lever 60 are provided. Are vertically opposed to each other with the position pin 41 at the parking position P interposed therebetween. Further, although the solenoid 10 is off, the key lock lever 81 cannot be moved in the opposite direction because the key lock cable 81 cannot be moved in the pulled state, and the lock lever 70 and the lock portion 72 thereof are in the position. It is rotated to a position facing the pin 41. That is, the stopper 84 is pulled by the key lock lever 50 via the key lock cable 81 and moves downward to a position where the rotation of the key rotor 83 is allowed, and the key rotor 83 rotates to the position shown in FIG. 84 cannot be moved, which prevents the key lock lever 50 from rotating.

In this state, even if the knob pin 44 is pushed to move the position pin 41 downward, the movement is restricted by the position pin 41 coming into contact with the lock portion 72 of the lock lever 70. This can prevent the shift lever 40 from shifting from the parking position P to the traveling position.

In order to shift the shift lever 40 from the parking position P to the traveling position, first, the engine key is inserted into the cylinder lock 80, and the key rotor 83 is turned to the on position ON, as shown in FIG. As a result, the restricting portion 83a retreats from the movement trajectory of the stopper 84 in the sliding direction, and the stopper 84 can move upward. However, the arm portion 50a of the key lock lever 50 is pressed by the position pin 41, and It is held at the position shown in FIG. Further, the solenoid 10 is turned on, the plunger 12 is attracted, and the lock lever 70 is held at the position for locking the position pin 41.

In this state, when the engine is started and the brake pedal is depressed, the solenoid 10 is turned off and the plunger 12 projects in the direction of arrow A (see FIG. 2) to rotate the lock lever 70 clockwise.

Here, when the knob button 44 is pressed to lower the position pin 41, the key lock lever 50 rotates counterclockwise integrally with the support lever 60 and is connected from the cam surface 73 of the lock lever 70. Since the pin 53 is separated, the lock lever 70 is rotated clockwise by the plunger 12. Then, as shown in FIG. 4, the hook portion 60b of the support lever 60 engages with the hook portion 74 of the lock lever 70, whereby the lock mechanism G can be held in the unlocked state.

In this state, by further pressing the knob button 44 to disengage the position pin 41 from the parking position P, the shift lever 40 can be shifted from the parking position P to the traveling position, and the vehicle is made to travel. be able to.

In order to remove the engine key from the traveling state described above, first, the shift lever 40 is shifted from the traveling position to the parking position while pressing the knob button 44. Then, the lever of the shift lever 40 contacts the contact of the micro switch, the solenoid 10 is turned on, the plunger 12 is attracted and the lock lever 70 rotates counterclockwise, and the hook portion 74 and the support lever 60 of the lock lever 70 rotate. The engagement with the hook portion 60b is released.

Here, when the knob button 44 is released, the position pin 41 engages with the upper end of the position groove 30a at the parking position P as shown in FIG. 3 due to the spring force of the compression spring. At the same time, the stopper 84 is pulled and moved by the key lock lever 50 via the key lock cable 81, and the key rotor 83 can be rotated to the lock position LOCK. At this point, the engine key can be removed.
