For this reason, the number of parts is large, and the number of assembling steps increases accordingly, and problems such as deterioration of operational feeling such as looseness, friction and overload due to accumulation of tolerances between parts, and damage to parts are likely to occur. It was.

  In the holder portion of the present invention, the assembly holding portion includes, in a state where the base portion is assembled, an axial direction slip-out preventing portion that prevents the base portion from slipping out in the neutral axis direction, and a diameter of the base portion with respect to the neutral axis line. It can have a radial direction slip prevention part for preventing slipping in the direction. With this configuration, the base part and the holder part can be securely held together.

  The holder part of this invention can form a sliding receiving part as an assembly | attachment holding | maintenance part. Specifically, the spherical portion of the base portion is configured to have an inward spherical portion exposed to the swing center side and an outward spherical portion exposed to the opposite side of the swing center, while the holder As the sliding receiving portion of the portion, the inward spherical portion has a contact direction on both the first side in the neutral axis direction and the first side in the radial direction with respect to the neutral axis, and the base in the contact direction The outward sliding receiving portion for preventing the part from slipping out, the outward spherical surface portion, the second side opposite to the first side in the neutral axis direction, and the first side in the radial direction with respect to the neutral axis line are opposite It has a contact direction on both of the second side and an inward sliding receiving portion for preventing the base portion from coming off in the contact direction. According to this configuration, while the outward sliding receiving portion and the inward sliding receiving portion contact the assembled base portion from both sides in the neutral axial direction, while functioning as the axial disconnection preventing portion, In addition, since it is configured to function as the radial slip-off prevention part by contacting the base part that is also assembled from both radial sides with respect to the neutral axis, the base part and the holder part can be assembled and held with a simple structure. It can be done reliably.

  Further, as a specific configuration, the rear end of the base portion is on the front side of the apparatus from the swing center, the inward spherical portion is the surface on the swing center side, and the outward spherical portion is opposite to the swing center. The inner wall has an outward sliding receiving portion that slides in contact with the sliding plate portion from the rocking center side while being configured as a sliding plate portion as a side surface. And an outer wall portion having an inward sliding receiving portion that slides in contact with the sliding plate portion from the side opposite to the swing center, and between the inner wall portion and the outer wall portion. It can comprise in the form which forms the space | gap which pinches | interposes a sliding plate part. According to this configuration, the base portion and the holder portion can be assembled and held with an extremely simple structure in which the curved plate portion is sandwiched from both sides by the inner and outer two wall portions.

  Further, in the above configuration, on the projection surface obtained by projecting the inner wall portion and the outer wall portion of the holder portion in the neutral axis direction, the gap-side end portions of the inner wall portion and the outer wall portion are spaced apart from each other by a predetermined width. Can be configured to According to this structure, the parting line of the metal mold | die which shape | molds the holder which is a resin injection molding body can be provided in the said predetermined width. Thereby, the parting line of a metal mold | die can be taken so that a burr | flash may not arise in the sliding surface (outer surface) of an inner wall part, and the sliding surface (inner surface) of an outer wall part.

  Moreover, in the holder part of the said structure, the end surface by the side of the space | gap of an inner wall part and an outer wall part can be made into the surface extended along a neutral axis line direction. According to this configuration, since the end surfaces on the air gap side of the inner wall portion and the outer wall portion can be made straight surfaces as if they were linearly cut along the neutral axis direction, the above-described predetermined width can be reliably provided.

  In the present invention, either or both of the outward sliding receiving portion and the inward sliding receiving portion protrude toward the spherical portion to be slid and extend in the extending direction of the arc-shaped sliding stroke. It can be formed as a protruding front end surface of the receiving rib. Thereby, the sliding operation force to the operation unit can be reduced, the operability can be increased, and the shape management of the sliding surface is facilitated. In particular, if the slide receiving portion facing forward in the neutral axial direction is formed as a protruding tip surface of the rib, it is possible to effectively support the backward force in the neutral axial direction received from the operation portion. Further, the slide receiving portion is formed as a protruding front end surface of a plurality of slide receiving ribs, and a lubricant accommodating groove portion can be formed between adjacent slide receiving ribs. Thereby, the lubricant can be held and supplied for a long time in the vicinity of the sliding receiving portion.

  By the way, in the present invention, the base part and the holder part are assembled in such a way that the base part and the holder part are brought close to each other in the neutral axis direction, and are set to a predetermined assembly reference position state in the neutral axis direction. A direction assembling operation, a circumferential assembling operation in which the base portion and the holder portion in the assembled state are rotated relative to each other around a neutral axis so that they are in a predetermined assembling completion position around the neutral axis; Can be configured to be As a result, the base part and the holder part can be easily assembled by a fitting operation in the neutral axis direction (axial direction assembly operation) and a rotation operation around the neutral axis line (circumferential direction assembly operation). Sexuality is improved. A fastening operation using a fastening member such as a screw is also unnecessary.

  In order to achieve this configuration, the holder portion is formed with a plurality of axial direction slip-out preventing portions around the neutral axis, and the base portion is formed with a plurality of spherical surface forming portions having a spherical portion around the reference axis. Furthermore, an axial assembly permission portion can be formed in the base portion between the spherical surface forming portions adjacent to each other around the reference axis. In addition, the axial direction assembly allowable portion is not obstructed by the axial direction omission prevention portion of the holder portion when the base portion and the holder portion are brought close to each other in the neutral axial direction by the axial direction assembly operation. This is a part that can reach the assembly reference position state. As a result, the base portion and the holder portion are rotated relative to each other around the neutral axis line by the circumferential assembly operation from the assembly reference position state to the assembly completion position state, so that the spherical surface portion of the spherical surface forming portion in the base portion can be handled. The sliding receiving portion is slidably positioned, and the spherical surface forming portion is prevented from being pulled out by the axial direction slip-out preventing portion and the radial direction slip-out preventing portion (the reference axial direction and its slip-out preventing state in the radial direction). It can comprise so that it may be hold | maintained. Thereby, reliable assembly | attachment of a base part and a holder part is realizable by simple assembly operation.

  Said axial direction assembly | attachment permission part can be used as the notch part provided in the form which divides | segments the spherical surface formation part of a base part around a neutral axis line. Thereby, an axial direction assembly | attachment permission part can be formed easily.

  In the present invention, either or both of the base part and the holder part may be provided with a circumferential assembly operation guide part for guiding relative rotation between the base part and the holder part by the circumferential assembly operation. Specifically, the circumferential direction assembly operation guide portion can be formed in a shape extending around the neutral axis with a spherical surface centered on the swing center. Thereby, the circumferential assembly operation can be easily performed. In addition, the circumferential assembly operation guide portion is simply formed by simply extending the spherical portion of the base portion extending in the swing operation direction of the operation portion in the circumferential direction perpendicular to the swing operation direction. There are also advantages that can be achieved.

  Further, in the present invention, the holder part is fixed on the substrate located behind the base part, and the base part has a plurality of arm parts projecting radially outward with respect to the reference axis around the neutral axis, On the upper side, in the assembly completion position state, it can be configured to have a pressing operation detection unit mounted at a position pressed by the arm unit in accordance with the swinging operation to the operation unit. Since the pressing operation detection unit is configured to be pressed by the arm portion protruding outward in the radial direction, the pressing operation stroke of the arm unit can be made longer, and the pressing operation detection unit accompanying the swinging operation to the operation unit Can be reliably pressed.

  Further, in the above configuration, the arm portion of the base portion can be provided around the reference axis corresponding to each swing operation direction defined in the operation portion. Thereby, it becomes a structure which can detect the rocking | fluctuation operation to each rocking | fluctuation operation direction reliably. At this time, the arm portion of the base portion can be formed at equal intervals around the neutral axis corresponding to the swinging operation direction of the operation portion.

  Further, the holder portion can be configured to have a plurality of fixing portions used for fastening and fixing to the substrate. In the above configuration, the plurality of fixing portions are assembled at positions where the holder portion and the base portion are assembled. When in a state, the base portion can be provided at an intermediate position between adjacent arm portions around the reference axis. According to this configuration, the force transmitted from the operation unit is supported by the fixed part on the substrate. However, since the fixed part is provided between the protruding parts arranged at equal intervals, the supporting force is increased. It is possible to effectively disperse each fixed part and prevent the action of local force.

  Further, in this case, when the holder portion has the above-described configuration in which the base portion includes the sliding plate portion and the holder portion includes the inner wall portion and the outer wall portion, the fixing portion of the holder portion starts from the lower end side of the outer wall portion. It can be formed to extend radially outward with respect to the neutral axis. Since the fixed portion that is uniformly arranged in the circumferential direction around the neutral axis is provided on the outer side from the axis, the force transmitted from the operation portion can be stably supported.

  In addition, the axial direction omission prevention part and fixing | fixed part of a holder part, the spherical surface formation part of a base part, an axial direction assembly | attachment permission part, and a protrusion part can be formed at equal intervals around a neutral axis line. According to this configuration, since the structure of the holder part and the base part is equalized in the circumferential direction, there is no place to receive local force when force is applied to the operation part, and the received force is distributed and effective. Can be supported.

  By the way, in the present invention, when the assembly operation in the axial direction is performed, the opposing surfaces of the base portion and the holder portion facing each other in the neutral axial direction satisfy a predetermined surface direction relationship that allows assembly and do not face each other. In this case, an assembly direction defining portion that prevents the base portion and the holder portion from approaching the assembly reference position state can be provided on either or both of the base portion and the holder portion, and satisfies the surface direction relationship. The base part and the holder part can be configured to be in the assembled reference position state only when they are opposed to each other. Thereby, directionality is provided in the assembly of the base portion and the holder portion, and assembly in an incorrect direction can be prevented.

  This assembling direction defining portion, when performing the axial direction assembling operation, when the facing surfaces of both the base portion and the holder portion do not face each other satisfying the above-described surface direction relationship, Provided in the holder part that contacts the base part in the neutral axis direction to prevent the approach while approaching the assembly reference position state, contacts the base part in the neutral axis direction to prevent the approach. Ribs. Thereby, directionality can be provided to the assembly of the base portion and the holder portion with the addition of a simple structure.

  Further, in the configuration in which the circumferential assembly operation guide portion formed so as to form a spherical surface centered on the swing center and extending around the neutral axis is formed, the base portion includes a plurality of around the reference axis. The axial direction assembly permission portion can be formed, and the circumferential direction assembly operation guide portion can be formed between the plurality of axial direction assembly permission portions. And when the circumferential direction assembly operation guide portion performs the axial direction assembly operation, when the opposing surfaces of the base portion and the holder portion do not face each other satisfying the above-described surface direction relationship, In addition to having an abutting portion that abuts and satisfying the surface direction relationship, the abutting avoiding portion for avoiding the abutting with the rib can be formed. With this configuration, by adding a structure in which a contact portion and a contact avoidance portion are provided in the circumferential assembly operation guide portion extending around the neutral axis, directionality is imparted to the assembly of the base portion and the holder portion. be able to. If the contact avoiding portion is formed as, for example, a notch portion, directionality can be imparted to the assembly of the base portion and the holder portion with the addition of a simpler structure.

  In the above configuration, when the base portion includes the sliding plate portion and the holder portion includes the inner wall portion and the outer wall portion, the holder portion includes a plurality of outer walls around the neutral axis. The rib can be formed corresponding to a part of the outer wall part of the plurality of outer wall parts and connect the part of the outer wall part and the inner wall part. In addition, the rib forming the assembling direction defining portion also functions as a reinforcing structure that increases the strength of the outer wall portion and the inner wall portion.

  Moreover, when giving directionality to the assembly of a base part and a holder part, it is good to employ | adopt the structure which provides directionality also to the assembly of an operation part and a base part. Specifically, the operation portion and the base portion are configured to be assembled in a form in which the rear end portion of the operation portion is fitted to the front end side opening of the cylindrical main body portion whose axis is the reference axis line of the base portion. In the case of the assembling, if the facing surfaces of both the operation portion and the base portion facing in the reference axis direction do not face each other satisfying a predetermined surface direction relation that can be assembled, the operation portion In addition, when the fitting of the base portion is impossible and the surfaces are opposed to each other while satisfying the plane direction relationship, the operation portion and the base portion can be fitted and assembled. More specifically, the rear end portion of the operation portion may be formed so that the outer peripheral surface of the rear end portion has an asymmetric shape that appears asymmetrically around the reference axis in a cross section perpendicular to the reference axis direction. On the other hand, the cylindrical main body portion of the base portion is formed such that the inner peripheral surface of the cylindrical main body portion has an asymmetric shape corresponding to the outer peripheral surface of the rear end portion of the operation portion, and the rear end portion Can be provided so as to be fitted. As a result, assembly in the wrong direction can be prevented in the three parts of the operation portion, the base portion, and the holder portion, which constitute the main structure of the vehicle input operation device of the present invention, and workability can be improved.

Is not possible, and it is configured so that it can be assembled only when it is opposed to satisfy the surface direction relationship, and the surface direction relationship is defined in a single way. Specifically, the assembling directionality is determined by the positional relationship of the claw engagement.

  The front end surface 450a of the push knob 450 is subjected to a coating process and then laser-cut so that only a predetermined character portion becomes transparent, and is illuminated by the light emitting diode 103 provided on the rear substrate 100. .

  Further, the push knob 450 is accommodated in an annular dial bezel 460. The dial bezel 460 is a decorative member obtained by plating the surface of ABS resin, for example, and is attached to the upper portion of the dial knob 430 by claw engagement.

  The knob slider 440 is a single resin injection molded body made of ABS resin or the like, and a rear end side shaft portion (rear end portion) 442 is fitted into an inner cylindrical portion (tubular main body portion) 380 of the base 300 described later. It is fixed. Specifically, the rear end side shaft portion 442 of the knob slider 440 is fitted into the front end side opening of the inner cylindrical portion (cylindrical main body portion) 380 of the base 300 whose axis is the common reference axis B with the knob slider 440. It is combined with. However, the direction of the assembly of the rear end side shaft portion 442 of the knob slider 440 and the inner cylindrical portion 380 of the base 300 is determined, so that only a predetermined assembly state can be taken. Yes. That is, the rear end side shaft portion 442 of the knob slider 440 and the inner cylindrical portion 380 of the base 300 are opposed to each other by satisfying a predetermined plane direction relationship that allows both opposing surfaces to be assembled to each other. If it is not, assembly is not possible, and it is configured so that assembly is possible only when facing the surface direction relationship, and the surface direction relationship is defined in a single way . Specifically, the outer peripheral surface 442a (402a) of the rear end side shaft portion 442 (402) of the knob slider 440 is formed in an asymmetric shape that appears asymmetrically around the reference axis B in a cross section perpendicular to the reference axis B direction. On the other hand, the inner peripheral surface 380b of the inner cylindrical portion 380 that forms the shaft portion 390 of the base 300 is also configured so that it can be fitted to the rear end portion 442 (402) of the knob slider 440 in a predetermined assembled state.

It is provided so as to slide in the reference axis B direction with respect to 300. The knob slider 440 is always urged forward (upward in the drawing) by a spring member (not shown) provided between the base slider 300 and the inner cylindrical portion 380, but is engaged with the inner cylindrical portion 380. This prevents the inner cylindrical portion 380 from coming off in the reference direction B.

  A switch push-down portion 443 is formed at the rear end of the rear end side shaft portion 442 of the knob slider 440. As shown in FIG. 5, the switch push-down portion 443 is disposed through the through hole 382 formed in the bottom portion 385 of the inner cylindrical portion 380 of the base 300 and penetrating in the reference axis B direction, and is mounted on the circuit board 100. The tact switch (pressing operation detection unit) 102 is always in contact. When the push knob 450 is not pressed, the contact position between the switch push-down portion 443 and the tact switch 102 and the position of the swing fulcrum O of the operation member 400 are on the same plane H perpendicular to the neutral axis A. It is set to be located at. The other through hole 383 formed in the bottom portion 385 is provided for irradiating the push knob 450 with the light of the light emitting diode 103.

  The dial knob 430 is a single resin injection molded body made of, for example, ABS resin, and has a cylindrical shape with the reference axis B described above as a rotation axis. While the outer peripheral surface 431a is used as a grip portion for the operator, a claw portion 433 protruding inward is formed on the inner peripheral surface 432b, and this claw portion 433 is formed inside the cylindrical shape of the dial knob 430. By engaging with the claw engaging portion 413 of the rotor 410 to be fitted, the rotor 410 is coupled to the rotor 410 so as to be integrally rotatable, and also prevents the rotor 410 from coming off in the reference axis B direction.

  The dial knob 430 in the present embodiment is formed in a double hollow cylindrical shape having an outer cylindrical portion 431 and an inner cylindrical portion (in this embodiment, an inner stepped cylindrical portion) 432. The outer cylindrical portion 431 functions as a gripping portion that can be operated by being picked by a finger with an operator, while the inner cylindrical portion 432 has a reference axis B direction around (a circumferential direction with respect to the reference axis B direction). The claw portions 433 are integrated with the rotor 410 by engagement between the claw portions 433 and the engagement hole portions 413 that form claw engagement portions of the rotor 410.

  The rotor 410 is a single resin injection-molded body made of, for example, POM resin or ABS resin, and is formed in a cylindrical shape having the above-described reference axis B as the axis. The outer cylinder forming the shaft portion 390 in the base 300 is formed. It is incorporated so as to be able to swing with the base 300 and to be rotatable about the reference axis B with respect to the base 300 so as to be sandwiched by a space between the portion 350 and the inner cylindrical portion 380. Note that a claw portion (not shown) provided on either or both of the rotor 410 and the base 300 prevents the rotor 410 from slipping out of the base 300 in the reference axis B direction.

  By the way, as shown in FIGS. 10 and 11, the rotor 410 is provided with flange portions 411 and 412 that protrude outward in the radial direction with respect to the reference axis B from the outer peripheral surface 410a. Among these, as shown in FIG. 12, the flange portion 411 has an uneven portion 413 that repeats radially outward unevenness around the reference axis B, and an inner side of the outer cylindrical portion 350 of the base 300. A rail portion 414 that slides in contact with the provided step portion 41 in the reference axis B direction is formed. In the present embodiment, the concavo-convex portion 413 and the rail portion 414 are formed adjacent to each other in the front-rear direction (reference axis B direction).

In addition, a through window portion 334 that penetrates in the radial direction with respect to the reference axis B is provided. While making contact with the outer peripheral surface 411a, both end support portions 34b at both ends of the central projecting portion 34a are connected to the peripheral portion 335 of the through-window portion 334 and the leaf spring holding portion 336 positioned on the radially outer side than the peripheral portion 335. Therefore, it arrange | positions in the form which hold | maintains a narrow pressure in this radial direction. Accordingly, as the dial knob 430 is rotated and the rotor 410 is rotated, the leaf spring 34 comes into contact with the protrusions and recesses of the outer peripheral surface 411a alternately and repeatedly at the center protrusion 34a. In some cases, the operator can feel a sense of moderation (click feeling) by performing an operation in which the central projecting portion 34a gets over the convex portion and reaches the concave portion.

  In addition, since the outer peripheral surface of the flange portion 411 is exposed from the through-window portion 334, it can be used as a lubricant injection window portion so that the lubricant can be applied from the window portion 334 to the outer peripheral surface of the flange portion 411. Good. In this case, by rotating the dial knob 430, the lubricant spreads in the circumferential direction of the outer peripheral surface of the flange portion 411. The surface to which the lubricant is applied at this time is shown in FIG. 12, and the outer peripheral surface 411 a of the uneven portion 413 that forms the flange portion 411, and the rail portion that also forms the flange portion 411 (formed adjacent to the uneven portion 413). A front end surface 411b of 414 and an outer peripheral surface 411c of the rail portion 414. The lubricant is distributed over the outer peripheral surface 411c of the rail portion 414 through a slight gap between the rail portion 414 and the base 300. Furthermore, since the lubricant is distributed to the base 300 (particularly, the region facing the rail portion 414 of the inner peripheral surface 350b) and the leaf spring 34 in proximity to the flange portion 411, the lubricant can be applied simultaneously from one place. It can be applied to three parts (rotor 410, base 300, leaf spring 34).

  In addition, an uneven slit 415 (see FIG. 1) is formed in the lower end portion of the rotor 410 in the circumferential direction. The uneven slit 415 functions to transmit or block infrared light from the photo interrupter 104 described later.

Further, the photo interrupter 104 is arranged at a position closer to the neutral axis A than the tact switch 101. As a result, the fluctuation of the height of the light shielding plate due to the rotation is small even when the operation member 400 is swung, so that the output value of the rotation sensor does not change. As a result, the rotation operation is performed even though the rotation operation is not performed. It is possible to prevent erroneous determination as having been performed. Further, during the swinging operation, the light shielding wall does not interfere with the side wall or bottom surface of the photo interrupter 104 and is not damaged or abnormal noise is not generated.

When the opposing surfaces of both the holder 300 and the holder 200 satisfy the above-described surface direction relationship and do not face each other, the holder 200 has an abutting portion 352 that abuts against the assembling direction defining rib 250 of the holder 200, and FIG. As shown to (a), when satisfy | filling the said surface direction relationship and facing, it has the contact avoidance part 351 which avoids contact | abutting with the assembly direction regulation rib 250, and is formed. Here, the contact avoiding portion 351 can have various shapes, but in FIG. 8, a notch surface 353 is formed by cutting out the peripheral portion around the reference axis B of the axial assembly permitting portion 331. It is formed as a notch part formed. On the other hand, the contact portion 352 is a portion around the reference axis B of the axial direction assembly allowing portion 331 and is a portion corresponding to the position of the notch portion 351.

  Furthermore, as shown in FIG. 9, the assembly direction defining rib 250 that forms the assembly direction defining portion is formed corresponding to a part of the outer wall portions 210 of the plurality of outer wall portions 210 around the neutral axis A, A part of the outer wall portion 210 and the inner wall portion 220 are formed so as to be connected to each other, which contributes to an increase in the strength of the holder 200.

  In addition, the outer wall portion 210 formed with the inward sliding receiving portion 211b at the front end portion is inward in order to reduce the notch width in the circumferential direction of the axial assembly permission portion 331 and improve the rigidity of the base 300. The front end portion of the outer wall portion 210 where the slide receiving portion 211b is formed has a tapered shape. The strength of the outer wall portion 210 is ensured by the outer wall portion reinforcing rib 211.
