  Then, the pressing portion 26D extending downward inside the button body 26 contacts the pressing button 27A of the central switch contact 27 via the pressing body 30, and the pressing portion 24D of the second driving body 24 via the pressing body 30. Are in contact with the push buttons 28A of the outer switch contacts 28, respectively.

  Further, when the button body 26 is pressed, the button body 26 is guided to the inside of the second drive body 24 and moves downward, and the push button 27A of the center switch contact 27 is pushed down via the pressing portion 26D. When the electrical contact / separation of the contact 27 is performed and the operating body 25 is swung to swing the second drive body 24 in a substantially intermediate direction between the first axis 22B and the second axis 24B, the pressing is performed. The outer switch contact 28 is electrically connected / disconnected by depressing the push button 28A of the outer switch contact 28 facing the portion 24D.

  The first axis 22B and the second axis 24B are arranged on the same plane that is substantially parallel to the upper surface of the holding body 22 when the operating body 25 is in a neutral state, and the first axis 22B and the second axis 24B. Is substantially coincided with the contact position of the pressing portion 26D and the pressing body 30 that contacts the pressing portion 26D.

  As a result, when the operating body 25 is swung in each direction, the tip of the pressing portion 26D remains stably at a predetermined position and is difficult to move in the vertical direction and the horizontal direction. In accordance with the operation, the distal end of the button body 26 moves downward, and the switch contact malfunctions such that the push button 27A is pushed down via the pressing body 30 to operate the central switch contact 27 are unlikely to occur.

Since the entire multi-directional operation switch becomes large because it is necessary to sequentially arrange on the same straight line extending outwardly with 22G as the center, as described above, the pair of shaft support portions 22A of the holding body 22 are moved back and forth, and left and right. Since the restricting portion 22C, the pressing portion 24D, and the outer guide portion 22H can be disposed at a substantially intermediate position between the disposing directions, the entire multi-directional operation switch becomes smaller.

  Reference numeral 31 denotes a plurality of screws, and 32 denotes a cover made of an insulating resin such as PBT or ABS. The cover 32 covers the lower surface of the wiring board 29, and the case 21, the holding body 22, the wiring board 29 and the cover 32 are covered with the screws 31. Are fastened and fixed to form the multidirectional operation switch 40.

  Then, as shown in the plan view of the steering in FIG. 9, the multi-directional operation switch 40 configured in this way, for example, between the steering wheel 15 and the center pad 15 </ b> A with the upper surface of the operating body 25 facing forward, for example, Attached to the left spoke 15B and mounted on the automobile, the central switch contact 27, the outer switch contact 28, etc. are connected to the vehicle electronic circuit (not shown) via a connector, a lead wire (not shown), etc. Is electrically connected.

  In the above configuration, when the thumb is extended while grasping the steering wheel 15 and the upper surface of the button body 26 is pressed in a neutral state where the operating body 25 is not tilted in any direction as shown in FIG. As shown in the sectional views of a) and (b), in the button body 26, the protruding portions 26B of all the arm portions 26A extending in the front-rear and left-right directions are inserted into the groove portions 22D of the regulating portions 22C facing downward. The button body 26 is guided to the inside of the second drive body 24 and moves downward, and the pressing portion 26D pushes down the push button 27A via the pressing body 30, and the central switch contact 27 is turned on. For example, input modes such as radio and music CD are sequentially switched.

  Further, when the operating body 25 is in a neutral state, for example, the left operating section 25B among the front, rear, left, and right operating sections 25B is pressed, the second driving body 24 locked to the operating body 25 becomes the first driving body. 23, the first driving body 23 rotates about the first axis 22B relative to the holding body 22, and the second driving body 24 rotates about the first axis 24B. It swings to the left which is a substantially intermediate direction between 22B and the second axis 24B.

  At this time, as shown in the cross-sectional view of FIG. 5 (a), the button body 26 swinging integrally with the second driving body 24 has a regulating portion 22C opposed to the protruding portion 26B of the left arm portion 26A. The button body 26 and the second driving body 24 are further swung to the lower left, and the pressing portion 24D immediately below the left arm portion 26A is tilted downward, so that the pressing body 30 is Then, the left push button 28A is pressed down, and the outer switch contact 28 is turned on. In response to this, for example, the music selection in the music CD of the audio apparatus and the radio frequency are switched in descending order by the electronic circuit of the vehicle.

  Further, when the operating body 25 swings to the left in this way, as shown in FIG. 5B, the front and rear arm portions 26A, which are perpendicular to the swinging direction of the button body 26, Since the protrusion 26B is displaced from the upper part of the groove 22D and faces the contact part 22E in the left direction of the groove 22D, the button body 26 is erroneously pressed at this time. The protrusion 26B is in contact with the lower contact portion 22E, and is restricted so that the button body 26 cannot move downward any further.

  That is, when the operating body 25 is in the neutral state, when the button body 26 is pressed, the button body 26 moves downward and the switch operation can be performed on the central switch contact 27, but when the operating body 25 is swung, Even if the button body 26 is accidentally touched and pressed, the projection 26B of the arm portion 26A arranged in a direction different from the swinging direction of the button body 26 is brought into contact with the contact portion 22E other than the groove portion 22D of the restriction portion 22C. Since the abutting and the downward movement of the button body 26 are restricted, an erroneous operation on the central switch contact 27 does not occur.

  Similarly, when the operating body 25 is pressed on the right side, the front side, or the rear side, the second driving body 24 and the button body 26 are similarly swung downward on the right side and the front and rear sides, and the second driving body 24 The external switch contact 28 facing the pressing portion 24D in the swinging direction is turned on, for example, the music selection in the music CD and the radio frequency are switched in ascending order in accordance with the swinging operation to the right side. Various operations of the audio device are easily performed with the thumb or the like while grasping the steering wheel 15 in accordance with the pressing operation of the operating body 25 to the left or right or front and rear, such as the volume of the audio device increasing or decreasing with the swinging operation of .

  When the operating body 25 is swung to the left, right, and left in the normal swinging direction, for example, to the left, the button body 26 is neutral as shown in the plan view excluding the operating body 25 in FIG. From the state, as shown in FIG. 6B, the distal end portion of the left arm portion 26A in the swinging direction of the button body 26 is guided to the width W1 on the outer peripheral side of the guide portion 22F above the opposing restricting portion 22C. For example, as shown in FIG. 6C, when the operating body 25 is swung in an oblique direction on the left rear side, the tip of the arm portion 26A is moved. The two outer switch contacts 28 on the left side and the rear side are erroneously operated simultaneously by being in contact with the inner sides of the outer peripheral portions of the left side and the rear side guide portion 22F so as not to be able to swing further obliquely. Only when the swing operation is performed in the normal swing direction, Only switch contact 28 is configured to operate.

  Further, as shown in the plan view of FIG. 7, the guide portion 22F made of substantially L-shaped ribs arranged symmetrically is slightly weaker in strength, but has a width W1 on the outer peripheral sides on both sides of the groove portion 22D. You may form with a pair of substantially rectangular rib which has.

  As described above, according to the present embodiment, the plurality of arm portions 26A extending outward are provided on the outer periphery of the button body 26, and the restricting portion 22C facing the arm portion 26A is provided on the upper surface of the holding body 22, The protrusion 26B is formed on the lower surface of the portion 26A, and the groove 22D is formed on the upper surface of the restricting portion 22C. When the operating body 25 is in the neutral state, all the protrusions 26A and the groove 22D are arranged to face each other, and the button body 26 holds. When the operating body 25 swings with respect to the body 22, the protrusion 26B arranged excluding the swinging direction is displaced and faces the contact part 22E other than the groove part 22D so as to face the button body 26. When the operation body 26 is in a neutral state, the protrusion 26B provided on the arm portion 26A is inserted into the groove portion 22D of the restriction portion 22C by restricting the downward movement of the multi-directional operation switch. Body 26 is down When the operating body 25 swings, the projection 26B of the arm portion 26A arranged excluding the swinging direction faces the contact portion 22E, and the button body 26 is moved. Even if the button 26 is pressed, the protrusion 26B contacts the contact portion 22E other than the groove portion 22D, and the downward movement of the button body 26 is restricted. Even if the button body 26 is pressed, the central switch contact 27 does not operate unintentionally, and a simple configuration prevents a switch contact from being erroneously operated and realizes a multi-directional operation switch capable of reliable operation. be able to.

  In the above description, the button body 26 is disposed in the opening 25A of the operating body 25, and the button body 26 moves up and down in accordance with the pressing operation on the button body 26 to operate the lower central switch contact 27. However, as shown in the perspective view of the main part of FIG. 8, the individual parts of the operating body and the button body are locked and fixed, or the operating body and the button body are resin-molded with a single mold. The operation body 35 formed integrally with the operation body 35 can also be implemented. When the operation body 35 is in a neutral state and the upper surface of the operation body 35 is pressed, the entire operation body 35 moves downward and the central switch is operated. By operating the contact 27 and the plurality of external switch contacts 28, the number of parts can be further reduced and the assembly can be simplified.

  In the above description, the projecting portion 26B is provided on the lower surface of the arm portion 26A, and the groove portion 22D is provided on the upper surface of the restricting portion 22C. However, the groove portion and the abutting portions on both sides thereof are provided on the lower surface of the arm portion. The present invention can be implemented even if the protrusions are provided on the upper surface of 22C.

  In the above description, the operation body 25 locked to the second drive body 24 has been described as a multidirectional operation switch that swings with the two axes of the first axis 22B and the second axis 24B. For example, in the operating body alone or the driving body to which the operating body is locked and the holding body that swings and holds the operating body, the upper surface portion of the holding body and the lower surface portion of the operating body or the driving body slide in a substantially spherical shape. The present invention can also be implemented in multidirectional operation switches having various configurations, such as a configuration in which the multidirectional operation is performed.

  Further, the push buttons 27A and 28A of the central switch contact 27 and the outer switch contact 28 have been described as being pressed by the pressing portions 26D and 24D via the pressing body 30, but the push buttons are extended upward to form the pressing body.
