The shift lever 10 is a shift body that changes the shift position by movement. The shift lever 10 includes a detent rod 11, a detent pin 12 interlocked with the detent rod 11, and the like. The control lever 20 is a member that interlocks with the shift lever 10 when the shift lever 10 is operated in the shift direction (front-rear direction). The control lever 20 is connected to a shift cable, and movement of the control lever 20 changes the shift position of the transmission.

(2) Indicator device 30
The indicator device 30 is a device that displays the shift position to the occupant. The construction of the indicator device 30 will now be described in detail with further reference to FIGS. FIG. 2 is a perspective view of the indicator device 30 according to this embodiment. FIG. 3 is an exploded perspective view of the indicator device 30 according to this embodiment. As shown in FIGS. 2 and 3 , the indicator device 30 includes an indicator plate 31 , a dummy cover 32 , a housing 33 , a LED (light emitting diode) substrate 34 and a substrate case 35 .

The housing 33 is a member to which each component of the indicator device 30 is attached. Specifically, the indicator plate 31 and the dummy cover 32 are attached above the housing 33 , and the substrate case 35 containing the LED substrate 34 is attached below the housing 33 . A shift lever through hole 334 , which is an opening, is provided in the center of the housing 33 , and the shift lever 10 passes through the shift lever through hole 334 . Further, the housing 33 has a release operation hole 333 that is an opening for releasing a release body (tip 414 of the first link 410 described later) that releases the shift lock to the outside. Further, the housing 33 has a first mounting hole 331 and a second mounting hole 332, which are openings to which the first mounting portion 321 and the second mounting portion 322 of the dummy cover 32 are respectively mounted. The first attachment hole 331, the second attachment hole 332, and the release operation hole 333 are spaced apart in the front-rear direction. As a result, even if the indicator device 30 is exposed to water in the vehicle interior and water enters either the first mounting hole 331 or the second mounting hole 332, the water does not enter the release operation hole 333. can be prevented.

The indicator plate 31 is a member that displays the shift position. "P" (parking), "R" (reverse), "N" (neutral), and "D" (drive) are printed on the indicator plate 31 from the front to the rear. To the left of these characters, "+" (plus), "S" (sequential), and "-" (minus) are printed from front to back. The shift position is changed by moving the shift lever 10 to a position corresponding to these characters. In other words, the characters on the indicator plate 31 corresponding to the position of the shift lever 10 indicate the shift position. Note that the shift lever 10 is positioned at "P" in FIG.

The dummy cover 32 is detachably attached to the housing 33 and is a cover that covers the release operation hole 333 . Each of the first mounting portion 321 and the second mounting portion 322 projecting downward from the dummy cover 32 is inserted into a first mounting hole 331 and a second mounting hole 332 provided above the housing 33 . The dummy cover 32 is attached to the housing 33 by being fitted and the like. The dummy cover 32 covers the release operation hole 333 while attached to the housing 33 .

The LED board 34 is a board having a plurality of LED light emitting elements. The light emitted by the LED light emitting element irradiates each character provided on the indicator plate 31 from below, thereby improving the visibility of each character. The LED board 34 may improve the visibility of the shift position by irradiating the character corresponding to the current shift position with stronger light.

(3) Shift lock mechanism 40
The shift lock mechanism 40 is a device that restricts movement of the shift lever 10 under predetermined conditions. The predetermined conditions are, for example, that the shift position is "P" and that the vehicle brake (brake pedal) is in the OFF state (not depressed). The configuration of the shift lock mechanism 40 will be described in detail with further reference to FIGS. 4 and 5. FIG. FIG. 4 is a right side view of the main parts of the shift lock mechanism 40 according to the present embodiment. FIG. 5 is a left side view of the main parts of the shift lock mechanism 40 according to the present embodiment. As shown in FIGS. 4 and 5 , shift lock mechanism 40 includes first link 410 , second link 420 and third link 430 .

The first link 410 is rotatably provided around a rotating shaft 411 . The first link 410 has an engagement hole 412 that engages with the engagement protrusion 422 of the second link 420 and a detent pin contact surface 413 that contacts the detent pin 12 of the shift lever 10 . The tip 414 of the first link 410 is a release body that releases the shift lock by the shift lock mechanism 40 by being pushed downward with a tool such as a flat-blade screwdriver, as will be described in detail later. The second link 420 is rotatably provided around a rotating shaft 421 . The second link 420 has an engaging protrusion 422 that engages with the engaging hole 412 of the first link 410 and a yoke 423 that is attracted by magnetic force. The third link 430 is rotatably provided around a rotating shaft 431 . The third link 430 has an electromagnet 432 that generates magnetic force when energized, and a detent pin contact surface 433 that contacts the detent pin 12 . The shift lock operation and shift lock release operation by the shift lock mechanism 40 will be described in detail below.

When the shift lever 10 attempts to move rearward (in the direction of "R" or the like) from the "P" position, the detent pin 12 contacts and presses the detent pin contact surface 433 of the third link 430. Third link 430 rotates. Here, when the vehicle brake is in the OFF state, the electromagnet 432 is not energized and the electromagnet 432 and the yoke 423 do not attract each other, so the third link 430 rotates independently. In this case, the detent pin contact surface 413 of the first link 410 comes into contact with the detent pin 12 and interferes with the movement of the detent pin 12, so that the movement of the shift lever 10 is restricted (that is, the shift is locked). ). On the other hand, when the vehicle brake is in the ON state, the electromagnet 432 is energized and the electromagnet 432 and the yoke 423 attract each other. Furthermore, due to the engagement between the engagement hole 412 of the first link 410 and the engagement projection 422 of the second link 420, the first link 410 rotates as the second link 420 rotates. As a result, the detent pin contact surface 413 of the first link 410 moves to a position where it does not interfere with the movement of the detent pin 12, so that the movement restriction of the shift lever 10 is released (that is, the shift lock is released). .

When the shift lock is manually released, the dummy cover 32 is removed from the housing 33 of the indicator device 30, a tool is inserted through the release operation hole 333 exposed in the vehicle interior space, and the tip 414 of the first link 410 is inserted into the tool. is pushed downward by . Then, the first link 410 rotates as the tip 414 is pushed down. Due to the engagement between the engagement hole 412 of the first link 410 and the engagement projection 422 of the second link 420, the second link 420 rotates as the first link 410 rotates. Further, as the second link 420 rotates, the yoke 423 of the second link 420 presses the electromagnet 432 of the third link 430, so that the third link 430 also rotates. As a result, the detent pin contact surface 413 of the first link 410 and the detent pin contact surface 433 of the third link 430 move to positions where they do not interfere with the movement of the detent pin 12, so that the movement of the shift lever 10 is restricted. be released.

(4) Plate 50 and Cable Bracket 60
Each member of the shift device 1 such as the control lever 20 , the indicator device 30 , the shift lock mechanism 40 and the cable bracket 60 is attached to the plate 50 . A plate 50 supports these components and is attached to the vehicle. Cable bracket 60 supports various cables related to shift device 1 .

<<2. Configuration of dummy cover >>
The configuration of the dummy cover 32 will be described in detail below with reference to FIG. FIG. 6 is a diagram showing an example of the configuration of the dummy cover 32 according to this embodiment. As shown in FIG. 6 , the dummy cover 32 includes a first mounting portion 321 , a second mounting portion 322 , a release operation hole covering portion 323 and a notch 324 .

The first mounting portion 321 is configured as a pair of mounting claws spaced apart in the front-rear direction, is inserted into the first mounting hole 331 of the housing 33, and is fitted to the inner wall of the first mounting hole 331. , the dummy cover 32 is locked to the housing 33 . The second mounting portion 322 is configured as an L-shaped hook, is inserted into the second mounting hole 332 of the housing 33, and is hooked to a projection (not shown) in the second mounting hole 332, Dummy cover 32 is locked to housing 33 . The first mounting portion 321 is provided on one end side (front) of the dummy cover 32 in the longitudinal direction (front-rear direction), and the second mounting portion 322 is provided on the other end side (rear side) of the dummy cover 32 in the longitudinal direction. be provided. With such a configuration, it is possible to efficiently lock the dummy cover 32 to the housing 33 . When the occupant removes the dummy cover 32 from the housing 33, first, the first mounting portion 321 is removed from the first mounting hole 331 using a tool. Next, the occupant removes the dummy cover 32 from the housing 33 by rotating the dummy cover 32 around the second mounting portion 322 that is caught in the second mounting hole 332 to eliminate the hooking. Even if the front side of the dummy cover 32 springs up due to the reaction force of the mounting claws when the first mounting portion 321 is removed from the first mounting hole 331, the dummy cover 32 does not support the second mounting portion 322. Rotate as a fulcrum. Therefore, the possibility of the dummy cover 32 popping out due to the reaction force is low, and loss of the dummy cover 32 is prevented. It is desirable that the front-back direction and left-right direction end portions of the first mounting portion 321 and the second mounting portion 322 are configured so as not to protrude outside the range of the design surface 325 when viewed from above.

The release operation hole covering portion 323 is a portion of the rear surface of the design surface 325 of the dummy cover 32 that covers the release operation hole 333 of the housing 33 when the dummy cover 32 is attached to the housing 33 . The release operation hole covering portion 323 prevents water from entering the release operation hole 333 when the indicator device 30 is submerged in the vehicle interior, thereby exhibiting water resistance.

The notch 324 is provided on the left side surface of the dummy cover 32 near the first mounting portion 321 . In particular, as shown in FIGS. 1 and 2, the notch 324 is provided at the boundary between the indicator plate 31 and the dummy cover 32, and the slit 36 is formed by the notch 324 and the right side surface of the indicator plate 31. be. The occupant can remove the first attachment portion 321 from the first attachment hole 331 by inserting a tool through the slit 36 . Moreover, by providing the slit 36 at such a boundary portion, the slit 36 can be made inconspicuous, and the design can be improved. Furthermore, by providing the slit 36 at such a boundary portion, the driver's seat, the slit 36, and the first mounting portion 321 are arranged in order from the left to the right. The removal operation performed by inserting the

What should be particularly noted about the configuration of the dummy cover 32 is that the first mounting portion 321, the second mounting portion 322, and the release operation hole covering portion 323 are separated from each other. Thereby, the release operation hole 333 of the housing 33 can be separated from the first mounting hole 331 and the second mounting hole 332 . Therefore, even if the indicator device 30 gets wet in the vehicle interior and water enters from the slit 36, it is possible to prevent water from entering the release operation hole 333 and improve water resistance. It becomes possible. Here, the separating direction is the longitudinal direction of the dummy cover 32 . As a result, the amount of separation between the release operation hole 333 and the first mounting hole 331 and the second mounting hole 332 can be increased, so that the water resistance can be further improved.

Another notable feature of the dummy cover 32 is that the notch 324 and the release operation hole covering portion 323 are separated from each other. With this configuration, the release operation hole 333 can be separated from the slit 36 . Therefore, even if the indicator device 30 gets wet in the vehicle interior and water enters from the slit 36, it is possible to prevent water from entering the release operation hole 333 and improve water resistance. It becomes possible. The separating direction is the longitudinal direction of the dummy cover 32 . As a result, it is possible to increase the amount of separation between the release operation hole 333 and the slit 36, so that it is possible to further improve the water resistance.

<<3. Comparison with comparative example>>
FIG. 7 is a diagram showing an example of the configuration of a dummy cover 900 according to a comparative example. As shown in FIG. 7, the dummy cover 900 includes a mounting portion 901 consisting of a pair of mounting claws, a release operation hole covering portion 902, and a slit 903. As shown in FIG. The dummy cover 900 is attached to the housing of the shift device by inserting and fitting the attachment portion 901 into the release operation hole. That is, the entire rear surface of the dummy cover 900 corresponds to the release operation hole covering portion 902 . A tool for removing the dummy cover 900 can be inserted into the slit 903 . Below, the effect of the dummy cover 32 according to the present embodiment described above will be described in comparison with the dummy cover 900 according to the comparative example.

According to the comparative example, the attachment portion 901 and the release operation hole covering portion 902 are formed at the same position. Therefore, when the indicator device is exposed to water inside the vehicle, water enters the release operation hole through the slit 903 or the boundary portion of the outer periphery. In contrast, according to the above configuration of the present embodiment, the first mounting portion 321, the second mounting portion 322, and the release operation hole covering portion 323 are provided separately. Accordingly, as described above, even if the indicator device 30 is exposed to water in the vehicle interior and water enters from the slit 36, it is possible to prevent water from entering the release operation hole 333. A higher water resistance than the comparative example is exhibited.

According to the comparative example, the slit 903 and the release operation hole covering portion 902 are formed at the same position. Therefore, if the indicator device is exposed to water in the passenger compartment and water enters from the slit 903, the water will enter the release operation hole. In contrast, according to the above configuration of the present embodiment, the notch 324 and the release operation hole covering portion 323 are provided apart from each other. Accordingly, as described above, even if the indicator device 30 is exposed to water in the vehicle interior and water enters from the slit 36, it is possible to prevent water from entering the release operation hole 333. A higher water resistance than the comparative example is exhibited.

According to the comparative example, the dummy cover 900 is configured to be as small as the release operation hole, and is locked to the housing only by a pair of mounting claws. Therefore, when the dummy cover 900 is removed, the dummy cover 900 may pop out due to the reaction force of the mounting claws and may be lost. In this respect, according to the above configuration of the present embodiment, even if the first mounting portion 321 is removed from the first mounting hole 331, the second mounting portion 322 remains hooked on the second mounting hole 332. Therefore, loss can be prevented. Further, according to the above configuration of the present embodiment, it is possible to follow the same removal method as in the comparative example, in which a tool is inserted through the slit to remove the mounting claw from the mounting hole.

According to the comparative example, the dummy cover 900 entirely covers the release operation hole. Therefore, the shape of the release operation hole appears as a parting line on the design surface of the shift device, and the layout of the release operation hole is also restricted. In contrast, according to the above configuration of the present embodiment, a partial region of the dummy cover 32 (that is, the release operation hole covering portion 323) covers the entire release operation hole 333. As shown in FIG. Therefore, since the shape of the release operation hole 333 does not appear as a parting line on the design surface of the shift device 1, a higher design property than that of the comparative example is exhibited. Further, since the position of the release operation hole 333 can be freely arranged as long as it is within the range of the dummy cover 32, the degree of freedom in layout can be increased more than in the comparative example. Furthermore, even if the light from the LED board 34 leaks through the release operation hole 333 , the light leakage can be concealed by the dummy cover 32 larger than the release operation hole 333 .

According to the comparative example, a slit 903 is provided in the center of the dummy cover 900 . Therefore, a weld could occur around the slit 903 . In contrast, according to the above configuration of the present embodiment, the notch 324 is provided in the dummy cover 32 instead of the slit 36 itself. Therefore, occurrence of weld can be prevented. Also, since the slit 36 is formed at the boundary between the indicator plate 31 and the dummy cover 32, the slit 36 can be made less conspicuous than in the comparative example.

<<4. Supplement >>
Although the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention belongs can conceive of various modifications or modifications within the scope of the technical idea described in the claims. It is understood that these also naturally belong to the technical scope of the present invention.

For example, the configurations of the first mounting portion 321 and the second mounting portion 322 are not limited to the example shown in FIG. 8 and 9 are diagrams showing another example of the configuration of the dummy cover 32 according to this embodiment. As shown in FIG. 8, the first mounting portion 321 may be configured as a single mounting claw. Also, as shown in FIG. 9, the second attachment portion 322 may be configured as a pair of attachment claws spaced apart in the left-right direction instead of hooks. The separation direction of the pair of mounting claws may be the front-rear direction, the left-right direction, or any other direction. Moreover, as the shape of the hook, various shapes such as a U shape can be adopted in addition to the L shape. Also, other attachment devices such as hinges may be employed instead of hooks. Furthermore, the number of attachment portions for attaching the dummy cover 32 to the housing 33 is not limited to two, the first attachment portion 321 and the second attachment portion 322, and may be one or three or more.

For example, in the above embodiment, both the first attachment portion 321 and the second attachment portion 322 are separated from the release operation hole covering portion 323, but the present invention is not limited to such an example. In the present invention, at least the first attachment portion 321 provided near the slit 36 (that is, the notch 324 ) should be separated from the release operation hole cover portion 323 . The second mounting portion 322 and the release operation hole covering portion 323 may not be separated from each other, and may overlap, for example. In other words, the second attachment hole 332 and the release operation hole 333 of the housing 33 may not be separated, and may be the same, for example. Since there is a low possibility that water will enter the second attachment hole 332 that is far from the slit 36 , even with such a configuration, the water resistance of the shift device 1 can be ensured.

For example, in the above embodiment, the notch 324 is formed in the dummy cover 32, but the present invention is not limited to such an example. For example, the notch may be provided on the indicator plate 31 side of the boundary portion between the indicator plate 31 and the dummy cover 32 . Even in that case, the notch and the dummy cover 32 can form a slit into which a tool for removing the first mounting portion 321 from the first mounting hole 331 can be inserted, and the above-described embodiment can be used. The slit can be made inconspicuous in the same manner as in the configuration of . Further, the position of the notch 324 is not limited to the boundary portion between the indicator plate 31 and the dummy cover 32. good too.

For example, in the above embodiment, the dummy cover 32 is attached to the housing 33 of the shift device 1, but the attachment target of the dummy cover 32 is not limited to this. For example, the dummy cover 32 may be attached to the instrument panel of the vehicle. Also, the portion covered by the dummy cover 32 is not limited to the release operation hole 333, and may be any portion that should be avoided from being exposed to water.
