The first spring and the second spring are compression coil springs. The first spring is stretched between the bottom wall (lower wall) of the first cylinder 18A and the proximal end surface (lower end surface) of the first pin 20A, and biases the first pin 20A toward the distal end. , the second spring is stretched between the bottom wall (lower wall) of the second cylinder 18B and the proximal end surface (lower end surface) of the second pin 20B, and biases the second pin 20B toward the distal end. There is.

A moderation plate 22 (see FIG. 2(C)) is fixed within the plate 12. A first plate 22A and a second plate 22B each having a substantially rectangular plate shape are provided at the front and rear ends of the moderation plate 22, and the first plate 22A slopes downward as it goes forward. At the same time, the second plate 22B is inclined downward toward the rear. A long rectangular plate-shaped connecting plate 22C is provided at the left end of the moderation plate 22, and the connecting plate 22C is arranged on the left side of the lever 14 and integrates the first plate 22A and the second plate 22B. is connected to.

The lower surface of the first plate 22A and the lower surface of the second plate 22B are a first surface 24 as a first biasing surface (biasing surface) and a second surface as a second biasing surface (biasing surface), respectively. 26, the tip end surface of the first pin 20A is brought into contact with the first surface 24 by the biasing force of the first spring, and the tip end surface of the second pin 20B is brought into contact with the second surface 26. They are brought into contact by the biasing force of a spring.

The front portion of the first surface 24 is a first inclined surface 24A, and the first inclined surface 24A is inclined inward in the radial direction of rotation of the lever 14 in the front-rear direction as it moves toward the front side. . The rear portion of the first surface 24 is a first maintenance surface 24B, and the first maintenance surface 24B is smoothly connected to the first inclined surface 24A, and as it goes toward the rear side, the lever 14 is moved forward and backward. It is slightly inclined in the radially outward direction.

The rear portion of the second surface 26 is a second inclined surface 26A, and the second inclined surface 26A is inclined inward in the radial direction of rotation of the lever 14 in the front-rear direction as it goes toward the rear side. ing. The front part of the second surface 26 is a second maintenance surface 26B, and the second maintenance surface 26B is smoothly connected to the second inclined surface 26A, and as it goes toward the front side, the lever 14 is moved in the front-rear direction. It is slightly inclined in the direction toward the outside in the rotational radial direction.

Next, the operation of this embodiment will be explained.

In the shift device 10 having the above configuration, the lever 14 is disposed at the H position, and in the first moderation mechanism 16A, the tip end surface of the first pin 20A is moved by the biasing force of the first spring to the moderation plate 22 (first plate 22A). ), and the first moderation mechanism 16A urges the lever 14 rearward. Further, in the second moderation mechanism 16B, the tip end surface of the second pin 20B is moved by the biasing force of the second spring to the second inclined surface 26A of the second maintenance surface 26B on the second surface 26 of the moderation plate 22 (second plate 22B). The second moderation mechanism 16B urges the lever 14 forward. The rearward biasing force applied to the lever 14 by the first moderation mechanism 16A and the forward biasing force applied to the lever 14 by the second moderation mechanism 16B are made the same, and the lever 14 is held at the H position. There is.

When the lever 14 is rotated from the H position to the front side (R position side, other side), in the first moderation mechanism 16A, the tip end surface of the first pin 20A resists the biasing force of the first spring. The first moderation mechanism 16A urges the lever 14 rearward as it is slid forward on the first inclined surface 24A of the first surface 24, and the first moderation mechanism 16A biases the lever 14 rearward. Power will be increased. Further, in the second moderation mechanism 16B, the tip end surface of the second pin 20B is slid forward with respect to the second maintenance surface 26B of the second surface 26 by the biasing force of the second spring, and the second moderation mechanism 16B is moved to the lever. 14 toward the front, and the forward biasing force exerted on the lever 14 by the second moderation mechanism 16B is maintained constant. Then, the biasing force applied to the lever 14 rearward by the first moderation mechanism 16A is made larger than the force applied to the front side against the lever 14 by the second moderation mechanism 16B, and the lever 14 is urged rearward.

Therefore, when the lever 14 is disposed in front of the H position and no rotational operating force is applied to the lever 14, the tip end surface of the first pin 20A is moved to the first surface 20 by the biasing force of the first spring. At the same time, the tip surface of the second pin 20B slides rearwardly against the first inclined surface 24A of the second surface 26 against the biasing force of the second spring. By sliding, the lever 14 is rotated rearward to the H position (returned to the H position).

When the lever 14 is rotated from the H position to the rear side (D position side, one side), the tip surface of the second pin 20B resists the biasing force of the second spring in the second moderation mechanism 16B. The second moderation mechanism 16B urges the lever 14 forward, and the second moderation mechanism 16B pushes the lever 14 forward. Power will be increased. Further, in the first moderation mechanism 16A, the tip end surface of the first pin 20A is slid rearward with respect to the first maintenance surface 24B of the first surface 24 by the urging force of the first spring, and the first moderation mechanism 16A is The lever 14 is urged rearward, and the rearward urging force of the first moderation mechanism 16A against the lever 14 is maintained constant. Then, the forward biasing force on the lever 14 by the second moderation mechanism 16B is made larger than the rearward biasing force on the lever 14 by the first moderation mechanism 16A, and the lever 14 is urged forward.

Therefore, when the lever 14 is disposed rearward from the H position and no rotational operating force is applied to the lever 14, the tip surface of the second pin 20B is moved to the second surface by the biasing force of the second spring. At the same time, the tip surface of the first pin 20A slides forward against the first maintenance surface 24B of the first surface 24 against the biasing force of the first spring. The lever 14 is rotated forward to the H position (returned to the H position).

Here, when the lever 14 is disposed at the H position, the tip end surface of the first pin 20A in the first moderation mechanism 16A is moved to the first inclined surface 24A on the first surface 24 by the biasing force of the first spring. The first moderation mechanism 16A is brought into contact with the end on the side of the first maintenance surface 24B, and the first moderation mechanism 16A is enabled to bias the lever 14 rearward. Further, in the second moderation mechanism 16B, the tip end surface of the second pin 20B is brought into contact with the end of the second inclined surface 26A on the second maintenance surface 26B side of the second surface 26 due to the urging force of the second spring, and The moderation mechanism 16B is enabled to bias the lever 14 forward.

As a result, when the lever 14 is rotated from the front side to the H position by the urging force of the first moderation mechanism 16A, the tip surface of the first pin 20A in the first moderation mechanism 16A is aligned with the first point of the first maintenance surface 24B. Not only does it not come into contact with the end of the second inclined surface 24A, but also the tip end surface of the second pin 20B in the second moderation mechanism 16B is not subjected to a rearward turning force by the second surface 26, so that the second end of the second inclined surface 26A It comes into contact with the side end of the maintenance surface 26B. Therefore, it is possible to suppress the generation of contact noise caused by the tip end surface of the second pin 20B contacting the end portion of the second inclined surface 26A on the second maintenance surface 26B side, and the lever 14 is attached to the H position from the front side. It is possible to suppress the generation of contact noise when being returned by force.

On the other hand, when the lever 14 is rotated to the H position from the rear side by the urging force of the second moderation mechanism 16B, the tip surface of the second pin 20B in the second moderation mechanism 16B The tip surface of the first pin 20A is not brought into contact with the end of the inclined surface 26A, and the front end surface of the first pin 20A is not subjected to a rotational force toward the front side by the first surface 24, so that the first inclined surface 24A is maintained in the first state. It is brought into contact with the end portion on the side of surface 24B. Therefore, it is possible to suppress the occurrence of contact noise caused by the tip end surface of the first pin 20A contacting the end of the first inclined surface 24A on the first maintenance surface 24B side, and the lever 14 is moved from the rear side to the H position. It is possible to suppress the occurrence of contact noise when returning by the biasing force.

In addition, the first moderation mechanism 16A increases the biasing force toward the rear side of the lever 14 by contacting the tip end surface of the first pin 20A with the first inclined surface 24A at the front side of the H position, and at the same time, at the rear side of the H position By contacting the tip end surface of the first pin 20A with the first maintenance surface 24B, the biasing force toward the rear side of the lever 14 is maintained. Therefore, it is possible to restrict the biasing side of the lever 14 by the first moderation mechanism 16A from being changed on the front side and the rear side of the H position. As a result, when the first pin 20A is made tiltable with respect to the first cylinder 18A due to play between the first pin 20A and the first cylinder 18A, the lever 14 can be rotated between the front side and the rear side of the H position. When the first pin 20A is tilted rearward with respect to the first cylinder 18A, the first pin 20A is tilted between the rear side and the front side with respect to the first cylinder 18A. It is possible to suppress generation of contact noise due to contact with the single cylinder 18A.

Moreover, the first moderation mechanism 16A always urges the lever 14 rearward. Therefore, in all rotational positions of the lever 14, it is possible to restrict the first moderation mechanism 16A from changing the urging side of the lever 14. As a result, when the first pin 20A is made tiltable with respect to the first cylinder 18A due to backlash between the first pin 20A and the first cylinder 18A, when the lever 14 is rotated through all rotational positions, the The state in which the first pin 20A is tilted rearward with respect to the first cylinder 18A can be maintained, and the first pin 20A is tilted between the rear side and the front side with respect to the first cylinder 18A and hits the first cylinder 18A. It is possible to suppress the generation of contact noise caused by contact.

On the other hand, the second moderation mechanism 16B increases the forward urging force on the lever 14 by contacting the second inclined surface 26A of the tip end surface of the second pin 20B on the rear side of the H position, and The forward urging force on the lever 14 is maintained by the contact of the tip end surface of the two pins 20B with the second maintenance surface 26B. Therefore, it is possible to restrict the biasing side of the lever 14 by the second moderation mechanism 16B from being changed on the rear side and the front side of the H position. As a result, when the second pin 20B is allowed to tilt relative to the second cylinder 18B due to backlash between the second pin 20B and the second cylinder 18B, the lever 14 cannot be rotated between the rear side and the front side of the H position. When the second pin 20B is tilted forward with respect to the second cylinder 18B, the second pin 20B is tilted between the front side and the rear side with respect to the second cylinder 18B. It is possible to suppress generation of contact noise due to contact with the cylinder 18B.

Furthermore, the second moderation mechanism 16B always urges the lever 14 forward. Therefore, in all rotational positions of the lever 14, it is possible to restrict the second moderation mechanism 16B from changing the urging side of the lever 14. As a result, when the second pin 20B is made tiltable with respect to the second cylinder 18B due to backlash between the second pin 20B and the second cylinder 18B, when the lever 14 is rotated through all rotation positions, the The state where the second pin 20B is tilted forward with respect to the second cylinder 18B can be maintained, and the second pin 20B is tilted between the front side and the rear side with respect to the second cylinder 18B and comes into contact with the second cylinder 18B. It is possible to suppress the occurrence of contact noise caused by contact.

Furthermore, as described above, the state in which the first pin 20A is tilted rearward relative to the first cylinder 18A is maintained, and the state in which the second pin 20B is tilted forward relative to the second cylinder 18B is maintained. Ru. Therefore, it is possible to suppress rattling of the lever 14 due to at least one of the tilting of the first pin 20A with respect to the first cylinder 18A and the tilting of the second pin 20B with respect to the second cylinder 18B.

Further, a first moderation mechanism 16A and a second moderation mechanism 16B are arranged on the front side and the rear side of the lever 14, respectively. Therefore, the biasing positions of the lever 14 by the first moderation mechanism 16A and the second moderation mechanism 16B can be separated, the wobbling of the lever 14 can be suppressed, and the operability of the lever 14 can be improved.

The shift position of No. 14 is changed from the front side to the rear side to the R position, H position, and D position (see (A) and (B) of FIG. 5), and the shift position is changed from the left side to the right side to the P position and H position. position and N position (see (A) and (B) of FIG. 6).

The first cylinder 18A of the first moderation mechanism 16A and the second cylinder 18B of the second moderation mechanism 16B (see FIG. 7(A)) are integrated on the front side and left side and the rear side and right side of the lever 14, respectively. The inside of the first cylinder 18A is opened diagonally upward to the front and left side, and the inside of the second cylinder 18B is opened diagonally upward to the rear and right side. The second pin 20B protrudes obliquely upward from the inside of the cylinder 18A to the front side and the left side, and the tip of the second pin 20B projects diagonally upward from the inside of the second cylinder 18B to the rear side and the right side.

The connecting plate 22C of the moderation plate 22 (see FIGS. 7B and 7C) is approximately disk-shaped and arranged vertically in the vertical direction, and the connecting plate 22C has a cross-shaped A regulation hole 22D is formed to penetrate. The lever 14 passes through the regulation hole 22D, and the circumferential surface of the regulation hole 22D defines the rotation range of the lever 14. The upper end of the first plate 22A and the upper end of the second plate 22B in the moderation plate 22 are integrated with the front side and left side and the rear side and right side of the connecting plate 22C, respectively, and the first plate 22A (including the first surface 24 ) and the second plate 22B (including the second surface 26) are curved along the circumferential direction of the connecting plate 22C.

The first inclined surface 24A of the first surface 24 is inclined in the direction inward in the radial direction of the rotation of the lever 14 in the front-rear direction as it moves toward the front side, and in the direction that moves inward in the radial direction of the rotation of the lever 14 in the left-right direction as it moves toward the left side. It is inclined in a radially inward direction. The first maintenance surface 24B of the first surface 24 is slightly inclined toward the outside in the radial direction of rotation of the lever 14 in the front-rear direction as it goes toward the rear side, and in the left-right direction of the lever 14 as it goes toward the right side. It is slightly inclined in the direction toward the outside in the rotational radial direction.

The second inclined surface 26A of the second surface 26 is inclined in a direction inward in the radial direction of the rotation of the lever 14 in the front-rear direction as it goes to the rear side, and as it goes to the right side, it is inclined in the direction inward in the radial direction of the rotation of the lever 14 in the left-right direction. It is inclined in the direction toward the inside in the radial direction. The second maintenance surface 26B of the second surface 26 is slightly inclined toward the outside in the radial direction of rotation of the lever 14 in the front-rear direction as it goes toward the front side, and is inclined slightly toward the outside in the radial direction of rotation of the lever 14 as it goes toward the left side. It is slightly inclined in the direction toward the outside in the rotational radial direction.

By the way, when the lever 14 is rotated from the H position to the left side (P position side, other side), the tip surface of the first pin 20A in the first moderation mechanism 16A resists the biasing force of the first spring. The first moderation mechanism 16A biases the lever 14 to the right, and the first moderation mechanism 16A urges the lever 14 to the right. Power will be increased. Further, in the second moderation mechanism 16B, the tip end surface of the second pin 20B is slid to the left with respect to the second maintenance surface 26B of the second surface 26 by the biasing force of the second spring, and the second moderation mechanism 16B is moved to the lever. 14 to the left, and the force exerted by the second moderation mechanism 16B on the lever 14 to the left is maintained constant. Then, the biasing force applied to the lever 14 to the right by the first moderation mechanism 16A is made larger than the biasing force exerted to the left on the lever 14 by the second moderation mechanism 16B, and the lever 14 is urged to the right.

Therefore, when the lever 14 is disposed to the left of the H position and no rotational operating force is applied to the lever 14, the tip end surface of the first pin 20A is moved to the first surface 20 by the biasing force of the first spring. The tip surface of the second pin 20B slides to the right against the second retaining surface 26B of the second surface 26 against the biasing force of the second spring. Then, the lever 14 is rotated to the right to the H position (returned to the H position).

When the lever 14 is rotated from the H position to the right side (N position side, one side), the tip surface of the second pin 20B in the second moderation mechanism 16B resists the biasing force of the second spring. When the second surface 26 is slid to the right with respect to the second inclined surface 26A, the second moderation mechanism 16B biases the lever 14 to the left, and the second moderation mechanism 16B biases the lever 14 to the left. will be increased.

Then, the biasing force applied to the lever 14 to the left by the second moderation mechanism 16B is made larger than the biasing force applied to the lever 14 to the right by the first moderation mechanism 16A, and the lever 14 is urged to the right.

At the same time, the tip end surface of the first pin 20A slides to the left against the first maintenance surface 24B of the first surface 24 against the biasing force of the first spring. Then, the lever 14 is rotated to the left to the H position (returned to the H position).
