The cover member 7 is made of a resin molded product, and has an insertion hole 7a at a corner thereof into which an engine key as an unlocking member can be inserted.

The shift lock mechanism, as shown in FIG.
A solenoid 15 having an extendable and retractable operating portion 15a, three arms extending in three directions (a first arm 16a, a second arm 16b as the other arm, and a third arm 16c as one arm) ) And a shift lock stopper 18 serving as a locking means. The shift lock stopper 18 is slid into a regulating hole 13a formed in the base end member 13 to perform insertion or removal. To lock or release the vertical rotation of the shift lever 3. In the state where the shift lock stopper 18 is inserted through the restriction hole 13a,
The shift lever 3 is designed to be in a parking (P) or neutral (N) position.

The operating member 16 is made of an oil-impregnated resin material. As shown in the figure, a shaft 4a protruding from the bracket 4 is inserted through a hole formed in a boss near the center. As a result, the second arm portion 16c has a convex portion 16d while being rotatable about the shaft portion 4a. The tip of the second arm portion 16b is formed on the shift lock stopper 18. The protrusion 16d is connected to the recess 18a, and is inserted into the hole at the tip of the operating portion 15a and assembled. Since the material of the operation member 16 is an oil-containing resin material, the rotation operation can be lubricated, and the operation noise at the connection with the other components such as the shift lock stopper 18 can be suppressed. .

On the other hand, as described above, the shift lock stopper 18 holds the base member 1 when the shift lever 3 is locked.
When a signal is transmitted from the vehicle to the solenoid 15 upon detecting that the brake has been depressed, the operating portion 15a is retracted from the state shown in FIG. The member 16 is rotated in the direction a in FIG. With this rotation, the shift lock stopper 18 connected to the second arm 16b slides in the direction b in FIG.
As shown in FIG. 4, the shift lever 3 is released from the restriction hole 13 a of the base end member 13 and the lock of the shift lever 3 is released.

Here, the tip of the second arm 16b (that is, the connecting portion with the shift lock stopper 18) has a notch 16ba extending in a direction substantially perpendicular to the sliding direction b of the shift lock stopper 18. The notch 16ba can absorb the impact at the slide end of the shift lock stopper 18. That is, the impact when the shift lock stopper 18 reaches the slide end is transmitted to the distal end of the second arm 16b of the operation member 16, where an operation sound is generated. Therefore, the second arm 1 is notched by the notch 16ba.
6b makes the tip easily deformable and absorbs the shock transmitted by the deformation.

Further, a cushioning member 16ca made of, for example, synthetic rubber is provided at the tip of the third arm portion 16c.
As shown in FIG. 5, the cushioning member 16ca can be brought into contact with the wall surface 4d at the pivotal end of the third arm 16c. The wall surface 4 d is a portion formed on the outer surface of the bracket 4, and is integrally formed when the bracket 4 is formed.

As shown in FIG. 8, the cushioning member 16ca has an acute angle portion P that protrudes in the radial direction d, and forms an abacus piece as a whole. And

As shown in FIG. 6, the cushioning member 16ca is
The acute angle portion P is always in contact with the bottom surface 4da surrounded by the wall surface 4d, and is set to slide or roll on the bottom surface 4da when the operation member 16 rotates. As described above, since the apex of the acute angle portion P comes into contact with the bottom surface 4da and slides or rolls, the cushioning member 1
The operation sound generated from 6ca can be suppressed.

On the other hand, when the operating member 16 is rotated to release the lock of the shift lever 3, as shown in FIG. 7, the second arm 16b slides the shift lock stopper 18 and pulls it out of the regulating hole 13a. , Third arm 16
c also rotates to bring the acute angle portion P of the buffer member 16ca into contact with the right side surface of the wall surface 4d in FIG. Thus, the third arm 1
By limiting the rotation range of the tip of 6c to the range within the wall surface 4d, the rotation range of the operation member can be restricted, and the buffer member 16ca has an acute-angled portion P that is convex in the radial direction. Therefore, the contact with the wall surface 4d is performed at one point or an area close thereto, and the impact sound (that is, the operation sound) at the time of the contact can be suppressed.

It is sufficient that the cushioning member 16ca has an acute angle portion protruding in the radial direction. In addition to the abacus piece as in this embodiment, the cushioning member 16ca may have a shape as shown in FIG. Good. Although the cushioning member 16ca 'in the figure has an acute angle portion P at the upper end, it may be configured to have an acute angle portion at the lower end.

The shift lock mechanism provided in the shift operation device 1 has been described above. However, since the unlocking of the shift lever 3 by the shift lock mechanism is exclusively performed by the operation of the solenoid 15, the battery of the vehicle rises. If a trouble occurs in the electric system, the lock cannot be released. In such a case, to manually forcibly release the lock of the shift lever 3, the speed change operation device 1 of the present embodiment includes the lever member 17 urged by the urging means 19.

The lever member 17 is rotated by inserting an engine key through the insertion hole 7a into the bracket, and releases the lock of the shift lever 3 by the shift lock stopper 18, as shown in FIG. It has an insertion hole 17c that can be inserted into the rotating shaft 4b protruding from the bracket 4 and is rotatably assembled around the rotating shaft 4b.

The lever member 17 has an insertion hole 7 at one end.
A key receiving portion 17a for receiving an engine key inserted from the bracket 4a is formed, and an operating portion 17b capable of rotating the operating member 16 is formed at the other end. Are assembled in a state of being urged in the direction c in FIG.

As shown in FIG. 11, when the key receiving portion 17a is pressed by the tip of the engine key KEY, the lever member 17 rotates, and with the rotation of the lever member 17, the operating portion 17b moves to the first position. The operation member 16 is rotated by pressing the one arm portion 16a, and the shift lock stopper 18 connected to the second arm portion 16b of the operation member 16 is slid toward the front of the drawing in FIG. Due to the sliding of the shift lock stopper 18, the tip of the shift lock stopper 18 comes out of the regulating hole 13a of the base member 13, and the lock of the shift lever 3 is forcibly released.

Although the present embodiment has been described above, the present invention is not limited to this, and is applicable not only to the automatic transmission operating device provided on the instrument panel 2 but also to the floor of the vehicle. It can also be applied to a type of automatic transmission operating device. Further, the present invention can be applied to an automatic transmission operating device that does not include the lever member 17 and does not have the forced lock release mechanism. That is, the arm portion of the operation member 16 only needs to have the second arm portion 16b and the third arm portion 16c, and the arm portion can be applied to the present invention.
