Then, the cam surface with the large diameter is set for a switch (2) for regulation of a push operation, and the cam surface with the small diameter is set for switches except the switch for regulation of the push operation.

According to the present example, for maximum of four switches, it becomes possible to simultaneously regulate their push operations by a single actuator.

Description

  The present invention relates to a push operation restricting device that restricts a push operation and a shift switching device including the push operation restricting device.

  In a vehicle equipped with a transmission, an input operation by an operation member such as a shift lever or a push button is detected by a sensor, and the detection result is reflected in the connection state of the transmission, for example, when the D range is selected through the input operation. The connection state of the transmission is switched to the forward gear stage. When the transmission connection state is switched to the forward gear as described above, the vehicle can travel forward, but the transmission connection state is not switched to the reverse gear during the forward traveling. Such a shift switching device is provided with a restriction mechanism that restricts an input operation by the operation member under a specific condition.

  In the restriction mechanism according to Patent Document 1, the first solenoid is provided between the neutral position and the selected position of the D range, and the plunger protrudes during driving of the first solenoid, whereby the input from the neutral position to the selected position of the D range. Operation is restricted. In addition, a second solenoid is provided between the neutral position and the R range selection position, and the plunger protrudes during driving thereof, thereby restricting the input operation from the neutral position to the R range selection position. . Therefore, in a vehicle equipped with this restricting mechanism, the input operation from the neutral position to the selected position of the R range can be restricted by driving the second solenoid during forward traveling that satisfies the above specific condition. By driving the first solenoid during the reverse travel as a condition, it becomes possible to regulate the input operation from the neutral position to the selected position of the D range.

JP 2002-248963 (paragraphs [0031] and [FIG. 5])

  However, if one actuator such as a solenoid is provided for one input operation pattern to be regulated, the number of actuators increases as the pattern increases, and the entire shift switching device including this increases in size. Invite. If it does so, mounting in the limited space like a vehicle will become difficult, and it will become disadvantageous also in cost.

  The present invention has been made paying attention to such problems, and its purpose is to be able to efficiently restrict the push operation even in a limited space, such as a compact push operation restriction device, And it is providing the shift switching apparatus provided with the push operation control apparatus.

  In order to achieve the above object, the invention according to claim 1 is directed to a plurality of operation members that are displaced over a standby position before a push operation and a press position after the push operation, from the standby position to the press. In a push operation restricting device for restricting a push operation to a position, the push operation restricting device includes a permissible means for permitting a push operation of the operation member and a restricting means for restricting a push operation of the operation member. The operation means is configured such that, when it is an object to be permitted, the permission means is set corresponding to the operation member, and when the object is a restriction object, the restriction means is set corresponding to the operation member. The gist is to provide a smaller number of actuators than the number of members.

  According to this configuration, it is possible to regulate the push operation to be regulated by a smaller number of actuators than the number of operation members. Therefore, it is possible to provide a compact push operation restricting device that can efficiently restrict the push operation even in a limited space.

  According to a second aspect of the present invention, in the push operation restricting device according to the first aspect, the actuator includes a moving member that rotates or linearly moves in response to a driving force from a power source, and is based on the movement of the moving member. The gist is that the permissible means and the restricting means are set for each of the plurality of operation members for each displacement position.

  According to the same configuration, for example, in a case where a pattern such as allowing the push operation of the first operation member and restricting the push operation of the second operation member is required, at a specific displacement position of the motion member, It is only necessary to set the restricting means for the second operating member while setting the allowing means for the first operating member. Further, when a pattern that restricts the push operation of the first operation member and allows the push operation of the second operation member is required, the first operation member is located at another displacement position of the motion member. Therefore, it is only necessary to set the permitting means for the second operating member while setting the restricting means. That is, it is only necessary to set the allowance means and the restriction means for each displacement position in such a manner that all required patterns are realized. Therefore, it is possible to deal with many patterns with a relatively simple configuration in which the displacement position of the moving member is adjusted through control of the power source.

  According to a third aspect of the present invention, in the push operation restricting device according to the second aspect, the motion member restricts a permissible position allowing a push operation of one specific operation member and a push operation of the operation member. A cam that is displaced over the restriction position is assigned to one operation member, and a plurality of cams defined as a number equal to the number of operation members includes a camshaft that rotates integrally with the shaft, For each rotational position of the rotational movement of the camshaft, at the rotational position, the permitting means is constituted by a cam at the permissible position, and at the rotational position, the restricting means is constituted by a cam at the restricting position. The gist is to be done.

  According to the same configuration, for example, when a pattern is required such that the push operation of the first operation member is permitted and the push operation of the second operation member is restricted, at a specific rotational position of the camshaft, The cam assigned to the first operation member may take the allowable position, and the cam assigned to the second operation member may take the restriction position. Further, when a pattern that restricts the push operation of the first operation member and allows the push operation of the second operation member is required, the first operation member is located at another rotational position of the camshaft. The cam assigned to the second operation member may take the restricting position, and the cam assigned to the second operation member may take the allowable position. That is, it is only necessary to set the cam for each rotational position in such a manner that all required patterns are realized. Therefore, many patterns can be handled by controlling the rotation of the camshaft.

  According to a fourth aspect of the present invention, in the push operation restricting device according to the second aspect, the motion member includes a shaft that rotates about a predetermined axis, and a peripheral surface of the shaft extends from the shaft. Along the direction, it is divided into a number of areas equal to the number of operating members, and that area is assigned to one operating member, and for each area, a push operation of a specific operating member is allowed. And a restricting portion for restricting the push operation of the operation member are set, and for each rotational position by the rotational movement of the shaft, the permissive means is configured by the region where the permissible portion is set at the rotational position. At the same time, the gist is that the restricting means is constituted by a region where the restricting portion is set at the rotational position.

  According to the same configuration, for example, in a case where a pattern that permits the push operation of the first operation member and restricts the push operation of the second operation member is required, The permissible portion of the area assigned to one operating member may be set, and the restricting portion of the area assigned thereto may be set for the second operating member. Further, when a pattern is required such that the push operation of the first operation member is restricted and the push operation of the second operation member is permitted, the first operation member is moved to the first operation member at another rotational position of the shaft. On the other hand, it is only necessary to set a restricting portion of the area assigned to it and to set an allowable portion of the area assigned to the second operation member. That is, it is only necessary to set the permissible portion and the restricting portion for each rotational position in such a manner that all required patterns are realized. Therefore, many patterns can be dealt with by controlling the rotation of the shaft.

  According to a fifth aspect of the present invention, in the push operation restricting device according to the second aspect, the moving member includes a slider that linearly moves along a predetermined straight line, and the slider extends along a direction in which the straight line extends. Are divided into a number of areas equal to the number of operating members, one of which is assigned to each operating member, and for each of the areas, a permissible portion that permits a push operation of a specific operating member and A restricting portion for restricting the push operation of the operation member is set, and for each slide position by the linear motion of the slider, the allowance means is configured by the set region of the allowance portion at the slide position, The gist of the invention is that the restricting means is configured by a region where the restricting portion is set at the slide position.

  According to this configuration, for example, when a pattern is required that allows the push operation of the first operation member and restricts the push operation of the second operation member, The permissible portion of the area assigned to one operating member may be set, and the restricting portion of the area assigned thereto may be set for the second operating member. Further, when a pattern is required such that the push operation of the first operation member is restricted and the push operation of the second operation member is permitted, the first operation member is moved to the first operation member at another slide position of the slider. On the other hand, it is only necessary to set a restricting portion of the area assigned to it and to set an allowable portion of the area assigned to the second operation member. That is, it is only necessary to set the permissible portion and the restricting portion for each slide position in such a manner that all required patterns are realized. Therefore, it is possible to deal with many patterns by performing slider slide control.

The gist of the invention according to claim 6 is that, in the push operation restricting device according to any one of claims 1 to 5, the plurality of operation members are arranged in a straight line.
According to this configuration, by arranging a plurality of operation members on a straight line, the structure of the actuator can be simplified, and the push operation regulating device can be made compact.

  In the invention according to claim 7, one specific operation member selected from a plurality of operation members displaced over the standby position before the push operation and the pressing position after the push operation is selected from the standby position. 7. The shift switching device according to claim 1, wherein when a push operation is performed to the pressing position, a shift range assigned to the operation member is selected, and a connection state of a transmission of the vehicle is switched. The gist of the invention is that it is provided with the described push operation restricting device.

  According to this configuration, among the push operations of the operation member that is operated when selecting the shift range of the vehicle, it becomes possible to regulate the push operation to be regulated.

  According to the present invention, it is possible to provide a compact push operation restriction device and a shift switching device including the push operation restriction device, such as being able to efficiently restrict a push operation even in a limited space.

Sectional drawing which shows the partial cross section structure about the structure of the push operation control apparatus which controls the push operation used as the object of regulation with the structure of a pushbutton switch.

  Hereinafter, an embodiment in which the present invention is embodied in a shift switching device that switches a connection state of a transmission of a vehicle will be described. In the shift switching device of this embodiment, a push button switch (hereinafter simply referred to as a switch) is used as an operation member operated to select a shift range, and one switch is assigned to one shift range. ing.

  As shown in FIG. 1, in the vicinity of the driver's seat, a switch 1 for selecting a P (parking) range, a switch 2 for selecting an R (reverse) range, a switch 3 for selecting an N (neutral) range, and a D (drive) ) Range selection switches 4 are gathered and arranged in a line. Each of the switches 1 to 4 has the same structure except for the characters stamped on the surface of the operation buttons.

  FIG. 2 shows the structure of the switch 2 for selecting the R range and the switch 4 for selecting the D range, and the structure of the switch 1 for selecting the P range and the switch 3 for selecting the N range is not shown. ing. The structure of the switch 2 will be described as a representative. The switch 2 includes an operation button 21 that is pushed by the user from the outside of the switch case 20 and an operation bar 22 that is interlocked with the displacement of the operation button 21. A coil spring 23 is provided inside the switch case 20, and the switch 2 is held at the standby position before the push operation in such a manner that the operation button 21 receives the urging force of the coil spring 23. The front end of the bar 22 is retracted so as to be flush with the bottom surface of the switch case 20. When the operation button 21 is pushed against the urging force, the switch 2 is displaced to the pressed position after the push operation while the operation button 21 is guided to the internal shape of the switch case 20. At this time, the tip of the operation bar 22 protrudes from the bottom surface of the switch case 20 so as to face the outside. Then, the displacement of the operation button 21 due to this push operation is detected by the detection sensor 24 provided in the switch case 20, that is, in this case, the selection operation of the R range is detected, and the connection state of the transmission changes to the reverse gear stage. It can be switched. When the push operation is released, the operation button 21 receives the urging force of the coil spring 23 and the switch 2 is held again at the standby position. In this case, the selected state of the R range is electrically Maintained.

  And in the operation area | region of each switch 1-4, the push operation control apparatus 50 which controls the push operation of the specific switch selected from the said switches 1-4 under the specific conditions is provided. This push operation restricting device 50 is engaged with a single motor 51 serving as a power source, a gear portion formed on an output shaft of the motor 51, and a gear 52 rotating with a reduction by a gear ratio thereto, and the gear A camshaft 53 is fitted in 52 and rotated integrally therewith. The camshaft 53 includes a shaft 60 that serves as a rotating shaft of the gear 52. The shaft 60 has a number equal to the number of the switches 1 to 4, that is, four in the present embodiment (only two are shown). A cam is fixed, and one cam is assigned to one switch.

  FIG. 2 shows a cam 62 assigned to the switch 2 for selecting the R range and a cam 64 assigned to the switch 4 for selecting the D range, as well as the cam assigned to the switch 1 for selecting the P range. The cam assigned to the N range selection switch 3 is not shown. The configuration of the cam 62 will be described as a representative with reference to FIG. 3. The cam surface formed along the circumferential direction of the cam 62 faces the front end of the operation bar 22 of the R range selection switch 2. The cam diameter defined as the distance from the rotation center to the cam surface is set in two stages. As the cam 62 rotates, when the small-diameter cam surface 62a faces the tip of the operation bar 22, the cam 62 takes an allowable position to permit the push operation of the switch 2, and the large-diameter cam surface 62b When facing the front end of the operation bar 22, a restriction position for restricting the push operation of the switch 2 is taken. When the cam 62 takes the restricting position, the tip of the operation bar 22 of the switch 2 held at the standby position is not in contact with the cam surface 62b, but is positioned so that the gap between the two is small. Yes. Therefore, when the switch 2 is pushed with the cam 62 in the restricted position, immediately after the operation, the tip of the operation bar 22 comes into contact with the large-diameter cam surface 62b, and the push operation is quickly restricted. .

  As shown in FIG. 2, a magnet 71 is attached to the end of the shaft 60, and a change in magnetic flux by the magnet 71 due to the rotation of the shaft 60 is detected at a required position facing the magnet 71. Thus, a magnetic sensor 72 for detecting the rotational position of the camshaft 53 is provided.

  Here, when the P range is selected, the switch 1 for selecting the P range, the switch 2 for selecting the R range, the switch 3 for selecting the N range, on the condition that the foot brake is depressed. All the switches 1-4 such as the D range selection switch 4 are allowed to be pushed. That is, under such a first condition, the small cam surface (62) of the cam (62) assigned to the switch with respect to the tip of the operation bar (typically 22) of each switch 1-4. The rotation of the camshaft 53 is controlled so that 62a) is at the opposite rotational position. Then, the rotational position of the camshaft 53 under the first condition is defined as the first rotational position. In the case where the P range is selected, when the foot brake is not depressed, the push operations of all the switches 1 to 4 are restricted. That is, under such a second condition, the large-diameter cam surface (62b) of the cam (62) assigned to the switch with respect to the tip of each operation bar (22) of each switch 1-4. The rotation of the camshaft 53 is controlled so that the rotation positions are opposed to each other. Then, the rotational position of the camshaft 53 under the second condition is defined as the second rotational position.

  On the other hand, when the R range is selected, the push operation of the D range selection switch 4 is restricted on condition that the vehicle speed is constant (for example, 10 km / h) or more, and other switches Push operations are allowed. That is, under the third condition, the large-diameter cam surface of the cam 64 assigned to the switch 4 faces the tip of the operation bar 42 of the switch 4 and each of the other switches. The rotation of the camshaft 53 is controlled so that the small cam surface of the cam assigned to the switch faces the tip of the operation bar. Then, the rotational position of the camshaft 53 under the third condition is defined as the third rotational position. In the case where the R range is selected, when the vehicle speed is less than a certain value, all the push operations of the switches 1 to 4 are permitted. That is, under the fourth condition, the small-diameter cam surface (62a) of the cam (62) assigned to the switch is located at the tip of the operation bar (22) of each switch 1-4. The rotation of the camshaft 53 is controlled so that the rotation positions face each other. Then, the rotational position of the camshaft 53 under the fourth condition is defined as a fourth rotational position. The fourth rotation position is substituted for the first rotation position.

  On the other hand, when the N range is selected, push operations of all the switches 1 to 4 are allowed. That is, under the fifth condition, the small-diameter cam surface (62a) of the cam (62) assigned to the switch is located at the tip of the operation bar (22) of each of the switches 1-4. The rotation of the camshaft 53 is controlled so that the rotation positions face each other. Then, the rotational position of the camshaft 53 under the fifth condition is defined as a fifth rotational position. The fifth rotational position is substituted for the first rotational position.

  Finally, when the D range is selected, the push operation of the R range selection switch 2 is restricted on condition that the vehicle speed is constant (for example, 10 km / h) or more, and other switches The push operation is allowed. That is, under the sixth condition, the large-diameter cam surface 62b of the cam 62 assigned to the switch 2 faces the tip of the operation bar 22 of the switch 2, and the other switches The rotation of the camshaft 53 is controlled so that the small cam surface of the cam assigned to the switch is opposed to the tip of each operation bar. Then, the rotational position of the camshaft 53 under the sixth condition is defined as the sixth rotational position. When the D range is selected, when the vehicle speed is less than a certain value, all the push operations of the switches 1 to 4 are permitted. That is, when the seventh condition is satisfied, the small-diameter cam surface (62a) of the cam (62) assigned to the switch is located at the tip of the operation bar (22) of each of the switches 1-4. The rotation of the camshaft 53 is controlled so that the rotation positions face each other. Then, the rotational position of the camshaft 53 under the seventh condition is defined as the seventh rotational position. The seventh rotational position is substituted for the first rotational position.

  Thus, for each rotational position of the camshaft 53, the push operation that is subject to restriction is restricted at that rotational position, and other push operations are allowed, so that each of the four cams (62), A small-diameter cam surface (62a) and a large-diameter cam surface (62b) are set. This is summarized as shown in FIG.

Next, the operation of the shift switching device will be described.
When various signals such as a brake signal related to a foot brake, a vehicle speed signal from a vehicle speed sensor, and a position signal from a detection sensor (typically 24) are acquired by a shift-by-wire electronic control unit (not shown), the control unit The push operation of the specific switch selected according to the grasped vehicle situation is regulated. For example, as shown in the second row from the bottom in FIG. 4, when the sixth condition is grasped as the vehicle situation, that is, when the D range is selected and the vehicle speed is 10 km / h or higher, in other words, the vehicle travels forward. In this case, the control unit restricts the push operation of the R range selection switch 2 and allows the other switches to be pushed. That is, the control unit monitors the rotation position detection signal from the magnetic sensor 72 while rotating the motor 51, and stops the rotation of the motor 51 at the timing when the camshaft 53 is stopped at the sixth rotation position. As a result, at the sixth rotational position, the large-diameter cam surface 62b of the cam 62 assigned to the switch 2 faces the tip of the operation bar 22 of the switch 2 for selecting the R range. The push operation of the switch 2 is restricted. Further, at the sixth rotation position, the small cam surface of the cam assigned to the switch is opposed to the tip of the operation bar of each of the three switches other than the switch 2, so that the three switches The push operation is allowed. Thus, when the vehicle is traveling forward at a vehicle speed above a certain level, only the push operation of the R range selection switch 2 is restricted.

  Thereafter, when the seventh condition is grasped as a new vehicle situation as the traveling speed of the vehicle is decelerated (see the lowermost stage in FIG. 4), the control unit controls all switches 1-4. Allow push operation. That is, the control unit monitors the rotational position detection signal from the magnetic sensor 72 while rotating the motor 51 from the state where the camshaft 53 is stopped at the sixth rotational position. The rotation of the motor 51 is stopped at the timing when it is stopped at the rotation position (substitute at the first rotation position). As a result, at the seventh rotational position, the small-diameter cam surface (62a) of the cam (62) assigned to the switch faces the tip of the operation bar (22) of each switch 1-4. Thus, the push operation of these four switches 1 to 4 is allowed. In this way, when the vehicle is traveling forward at a vehicle speed less than a certain level, push operations of all the switches 1 to 4 are permitted.

  Although the detailed description of other control modes is omitted, the motor 51 is controlled to rotate so that the camshaft 53 is stopped at a rotation position suitable for the new vehicle situation after the change every time the vehicle situation changes. Is done.

  Here, for each of the four cams (typically 62), the small-diameter cam surface (62a) faces the tip of the operation bar (22) of the switch (2) to which the cam is assigned. At this time, this cam is defined to be in the “allowable position”, and the cam in the allowable position corresponds to “allowable means”. On the other hand, for each of the four cams (62), when the large-diameter cam surface (62b) faces the tip of the operation bar (22) of the switch (2) to which the cam is assigned, The cam is defined to be in the “restricted position”, and the cam in the restricted position corresponds to “restricting means”. In this embodiment, the camshaft 53 having four cams (62) corresponding to the above-mentioned permissible means and the above-mentioned restricting means corresponds to a “rotating motion member”, and the camshaft 53 and a motor for rotating it. An “actuator” is configured to include 51 and a gear 52. The number of the cams (62) is four, which is equal to the number of the switches 1 to 4, but the number of the camshafts 53 fixed to one shaft 60 so that they are rotated synchronously with each other is one. In addition, the number of motors 51 and gears 52 that are “power sources” for rotating the single camshaft 53 is one. From this, the number of actuators is defined as a number (one in this embodiment) smaller than the number of switches 1 to 4 each corresponding to an “operation member”.

As described above, according to this embodiment, the following effects can be obtained.
(1) The actuator mainly including the camshaft 53 includes a total of four cams (62), one for each switch (typically 2), and each cam (62) has a small diameter. A cam surface (62a) and a large-diameter cam surface (62b) are provided. Then, a large-diameter cam surface (62b) is set corresponding to the switch (2) subject to the restriction of the push operation, and a small-diameter cam surface (62a) is set corresponding to the other switches. Here, the number of actuators smaller than the number of switches 1 to 4 restricts the push operation that is subject to restriction. According to this example, it becomes possible to simultaneously control the push operations of up to four switches 1 to 4 by a single actuator. Therefore, it is possible to provide a compact push operation restricting device 50 such that the push operation can be efficiently restricted even in a limited space. As a result, a compact shift switching device can be provided.

  (2) As shown in FIG. 4, the rotational position of the camshaft 53 is defined for each of the seven conditions such as the first condition to the seventh condition, and a small diameter is provided for each of the switches 1 to 4 for each rotational position. A cam surface (62a) and a large-diameter cam surface (62b) are set. Here, the cams (62) for each rotational position of the camshaft 53 may be set in such a manner that four restriction patterns such as patterns 1 to 4 are realized. Therefore, it is possible to deal with many patterns with a relatively simple configuration in which the rotational position of the camshaft 53 is adjusted through the rotation control of the motor 51.

  (3) The switches 1 to 4 are arranged in a row, and the actuator is mainly composed of a single camshaft 53 having a total of four cams, each cam being assigned to one switch. Thus, by arranging the switches 1 to 4 on a straight line, the structure of the actuator can be simplified, and the push operation restricting device 50 and the shift switching device can be made compact.

  (4) Even if the number of switches subject to regulation is large, it is not always necessary to increase the number of actuators, and it is possible to cope with the number of cams. In this way, all push operations to be regulated can be regulated simultaneously by simply selecting the number of cams according to the number of switches.

  (5) Since the four cams are synchronously rotated by controlling the rotation of the single motor 51, it is easy to synchronize each cam in comparison with a configuration in which one power source is assigned to one cam. Moreover, it can contribute to the downsizing of the apparatus.

  (6) Since the restricting structure based on the rotation of the cam is adopted, the occupied area due to the moving locus of the movable body can be narrowed compared with the restricting structure based on the link mechanism. In this respect as well, it is possible to contribute to downsizing of the apparatus, and it is easy to mount in a limited space such as a vehicle.

  (7) Instead of mechanically restricting the push operation to be regulated according to this example, the shift range is not switched by electrically invalidating the push operation while mechanically allowing the push operation. It is also possible to do so. However, in such a configuration, from the user's standpoint, it is impossible to immediately distinguish whether the push operation performed by the user has been invalidated or validated. In this respect, according to the present example, a tactile sensation due to mechanical regulation can be obtained. Therefore, from the user's standpoint, it can be felt with the skin that the push operation is invalidated.

In addition, the said embodiment can also be changed and actualized as follows.
In the above embodiment, the push operation is permitted and restricted using the cam. However, as shown in FIG. 5, a notch recess is provided on the peripheral surface of the shaft, and the push operation is permitted when the switch is opposed thereto. In addition, the push operation may be restricted when the switch faces a portion where the notch recess is not provided on the peripheral surface of the shaft. In this case, the shaft 80 (movement member) rotates around a predetermined axis, and the circumferential surface of the shaft 80 is equal to the number of switches 1 to 4 along the direction in which the axis extends, i.e. In the example, it is divided into four areas (only two are shown), and one area is assigned to one switch. In FIG. 5, in the region 82 assigned to the R range selection switch 2, the notch recess 82 a (allowable portion) that allows the push operation of the switch 2 faces the switch 2, and the D range selection In the region 84 assigned to the switch 4, a state in which the regulating surface 84 b (regulating portion) that regulates the push operation of the switch 4 faces the switch 4 is shown.

  Also in this case, in a manner similar to FIG. 4, for each rotational position of the shaft 80, the push operation to be regulated is regulated at that rotational position, and other push operations are allowed. A notch recess (82a) and a regulation surface (84b) are set for each of the two regions (typically 82 and 84). Here, the area (82) in which the “permissible part” is set corresponds to “allowing means”, and the area (84) in which the “restricting part” is set corresponds to “restricting means”. According to this configuration, it is possible to achieve the same effect as the effect (2) according to the above embodiment. That is, it is only necessary to set notch recesses and restriction surfaces for each rotational position of the shaft 80 in a manner in which four restriction patterns such as patterns 1 to 4 shown in FIG. 4 are realized. Therefore, many patterns can be handled by controlling the rotation of the shaft 80.

  As shown in FIG. 6, when the notch recess is provided in the slider and the switch faces it, the push operation is allowed, and when the switch faces the portion of the slider where the notch recess is not provided, the push operation is restricted. It is good also as composition to be. In this case, the slider 90 (movement member) receives a driving force from the motor 51 (for example, a linear motor) and linearly moves along a predetermined straight line, and the slider 90 moves along the direction in which the straight line extends. It is divided into a number equal to the number of ~ 4, that is, in this example, four areas (only two are shown), and one area is assigned to one switch. A solenoid may be used as a power source instead of the linear motor. In FIG. 6, in the region 92 allocated to the R range selection switch 2, a notch recess 92 a (allowable portion) that allows the push operation of the switch 2 faces the switch 2, and for the D range selection In the region 94 assigned to the switch 4, a state in which a regulating surface 94 b (regulating portion) that regulates the push operation of the switch 4 faces the switch 4 is shown.

  Also in this case, in a manner similar to FIG. 4, for each slide position of the slider 90, the push operation to be regulated is regulated at the slide position, and other push operations are allowed. A notch recess (92a) and a restriction surface (94b) are set for each of the two regions (typically 92 and 94). Here, the area (92) in which the “permitted part” is set corresponds to “allowing means”, and the area (94) in which the “restricting part” is set corresponds to “restricting means”. According to this configuration, it is possible to achieve the same effect as the effect (2) according to the above embodiment. That is, it is only necessary to set the notch recess and the regulation surface for each slide position of the slider 90 in a mode in which four regulation patterns such as the patterns 1 to 4 shown in FIG. 4 are realized. Therefore, it is possible to cope with many patterns by performing the slide control of the slider 90. Incidentally, in this example, the magnetic sensor 72 detects the change in the magnetic flux caused by the slide of the slider 90 (linear displacement), so that the slide position of the slider 90 is detected. Used to adjust the slide stop position.

  Although not shown, a protrusion is provided on the surface of a moving member such as a camshaft or a slider, and the push operation is restricted when the switch faces the protrusion, and the switch faces a portion of the moving member where the protrusion is not provided. In this case, the push operation may be allowed.

  -It is not limited to the structure by which the several operation member (push button switch) is arrange | positioned on a straight line. For example, when a plurality of operation members are interspersed, an actuator in which a plurality of motion members are connected by several gears may be used so that the permission means and the restriction means are set for each operation member. As described above, by appropriately changing the construction mode of the actuator, it is possible to restrict the push operation to be restricted even when a plurality of operation members are scattered.

  In the above embodiment, the magnet 71 is provided in the movable part and the magnetic sensor 72 is provided in the fixed part. However, by reversing this arrangement relationship, the magnet 71 is provided in the fixed part and the magnetic sensor 72 is movable. It may be provided in the part. Note that these detection systems are not limited to the magnetic type according to the above-described embodiment. For example, the detection system may detect light emitted from a light emitter such as a light emitting diode with an optical sensor, that is, an optical type. Good.
