The side stand spring L applies an urging force to the side stand T to hold the side stand T in the stand position or the storage position, and when the side stand T is in the stand position, as shown in FIG. The biasing force is applied to contact the bracket F to hold the position, and when the side stand T is in the storage position, the biasing force is applied to the side stand T in the direction of arrow b as shown in FIG. Then, it abuts on the bracket F to hold its position.

  The rotating member 2 is rotated along with the swing between the stand position of the side stand T and the storage position, and as shown in FIG. 3, the side wall covering the side of the head Ba of the mounting bolt B It consists of a substantially cylindrical member which has 2a and the recessed part 2b to which the integral member 3 is attached. The side wall 2a is a portion integrally formed on the lower surface of the rotating member 2 in an annular shape, and the head Ba of the mounting bolt B is positioned in the space A surrounded by the side wall. There is.

  The recess 2 b is a portion formed in an annular shape on the upper surface of the rotating member 2, and is formed in a shape following the outer contour of the integral member 3. Then, when the integral member 3 is fixed to the concave portion 2b (in the present embodiment, insert molding), the head Ba of the mounting bolt B is positioned in the space A and the screw portion Bb is integral as shown in FIG. The central hole 3 b of the member 3 can be inserted.

  As shown in FIG. 5, the integral member 3 has a locking portion 3a that can be locked to the side stand T, and a threaded portion Bb of the mounting bolt B, and a tightening portion 3b that receives the tightening force of the mounting bolt B. A plurality of through holes 3c which are filled with a resin at the time of insert molding are formed, as well as made of a disc-like metal member (for example, iron) in which is formed. The integral member 3 according to the present embodiment is formed by pressing a metal plate to integrally form the locking portion 3a and the tightening portion 3b. The locking portion 3a is formed by bending the edge portion of the metal plate. The clamping portion 3 b is formed by bending and projecting in a direction substantially orthogonal to the plane, and the clamping portion 3 b is formed by punching the center of the metal plate.

  Thus, when the position detection device 1 of the side stand is attached to a motorcycle, as shown in FIG. 6, the engagement portion 3a is inserted into and engaged with the engagement hole Ta formed in the side stand T, and the attachment bolt The tightening force when B is tightened to the stepped bolt D can be received at the opening edge of the tightening portion 3a. Thereby, the integral member 3 receives the load (rotational torque) applied as the side stand T swings, and the tightening force (tightening torque) by the mounting bolt B is tightened by the locking portion 3a. Are received at the opening edge of the

  The locking portion 3a and the tightening portion 3b may be formed simultaneously by one press process, or may be formed by a plurality of press processes. The plurality of through holes 3c are formed by press processing (punch processing) in the same manner as the locking portion 3a and the tightening portion 3b, and the same step or a separate step as the locking portion 3a and the tightening portion 3b. It is formed by Further, the shape of the integral member 3 is not limited to the substantially disc shape as in the present embodiment, and is an integral member in which the locking portion 3a is formed at a predetermined portion and the tightening portion 3b is formed at another portion. If it is, it may be another shape such as a rectangular shape or an irregular shape.

  On the other hand, the rotation member 2 is formed by resin molding other than the integral member 3, and the fixing member 3 is fixed to the recess 2 b by insert molding. Then, since the resin is filled in the through holes 3c of the integral member 3 and solidified by the insert molding, the integral member 3 can be fixed to the rotary member 2 more firmly. Note that, instead of insert molding, the integral member 3 may be fixed by a general purpose screw, an adhesive, or the like.

  The housing case 4 rotatably accommodates the rotating member 2 and is configured to have a locking claw 4a, a locking groove 4b, a central hole 4c, and a resin mold portion 4d. As shown in FIG. 2, a plurality of (four in the present embodiment) locking claws 4a are formed at substantially equal intervals at the edge of the opening where the rotary member 2 etc. can be inserted into the housing case 4 as shown in FIG. In the state where all the components are accommodated in the accommodation case 4, the components (the seal member S2) can be locked by being deformed inward by heat.

  The locking groove 4b is formed of a portion capable of locking the bracket pin P formed to be protruded from the vehicle body when the position detection device 1 of the side stand is attached to the vehicle body. The central hole 4c is a portion through which the mounting bolt B can be inserted and a tool or the like for rotating the head Ba can be inserted. As shown in FIG. 4, the resin mold portion 4d is composed of a portion where the connection ends 7aa and 7ba of the terminal boards 7a and 7b to the wiring H are located, and after the wiring H is connected to the connection ends 7aa and 7ba Is filled with resin and solidified.

  The movable contact 5 and the terminal boards 7a and 7b constitute the position detecting means of the present invention, and by detecting the rotation of the rotating member 2, it is possible to detect whether the side stand T is in the stand position or the storage position. It is assumed. Specifically, the movable contact 5 is attached to the rear surface side edge portion of the rotating member 2, and the terminal plates 7 a and 7 b are fixed by insert molding to a portion facing the movable contact 5. The movable contact 5 is biased toward the terminal plates 7a and 7b by the spring 6, and a contact pressure is applied to the terminal plates 7a and 7b.

  Then, when the rotary member 2 rotates with the swing of the side stand T, the movable contact 5 slides on the terminal plate 7a or 7b. For example, when the side stand T is in the stand position, the movable contact 5 is When the side stand T is in the storage position, the movable contact 5 is in contact with the terminal plate 7a and the terminal plate when the side stand T is in the storage position while the current does not flow in the wiring H by contacting only one of the terminal plate 7a or 7b A current flows in the wiring H in contact with both 7b, and is turned on. Thus, it is possible to detect that the side stand T is in the stand position when in the off state, and that the side stand T is in the storage position when in the on state.

  The seal member S1 is disposed between the side wall 2a of the rotary member 2 and the position of the position detection means (the movable contact 5 and the terminal plates 7a and 7b), and allows rotation of the rotary member 2 It is sealable. The seal member S2 is disposed along the edge of the opening through which the rotary member 2 and the like can be inserted into the housing case 4 and can seal while allowing the rotary member 2 to rotate. The reference numeral 8 in FIGS. 2 and 3 indicates an annular plate disposed below the seal member S1.

  In order to mount the position detection device 1 of the side stand according to the present embodiment to the vehicle body of a two-wheeled vehicle, as shown in FIG. 6, the lock portion 3a is inserted into the lock hole Ta to lock the side stand T, and a mounting bolt B is inserted from the central hole 4a of the housing case 4 and the screw portion Bb is formed on the stepped bolt D (rotation shaft of the side stand T) until the head Ba abuts against the opening edge of the tightening portion 3b It is inserted into the hole Da and screwed. A female screw that can be screwed with the screw shape of the screw portion Bb is formed on the inner peripheral surface of the mounting hole Da, and can be screwed by meshing with the screw portion Bb of the mounting bolt B.

  Thus, the rotary member 2 is fastened and fixed by the mounting bolt B to the stepped bolt D (rotational shaft) of the side stand T that rotates with the swing of the side stand T. When the side stand T swings between the stand position and the storage position about the stepped bolt D, the step bolt D rotates with the side stand T, so that the rotating member 2 swings the side stand T. Rotate by an angle corresponding to the movement angle. When the position detection means (the movable contact 5 and the terminal plates 7a and 7b) detects the rotation of the rotation member 2, it is possible to detect whether the side stand T is at the stand position or the storage position.

  Here, in the present embodiment, the head Ba of the mounting bolt B is configured to be positioned in the housing case 4. That is, since the space A formed in the housing case 4 is set such that the depth dimension α (dimension from the opening to the bottom surface) is larger than the dimension of the head Ba of the mounting bolt B, the head Ba Can be prevented from protruding outward from the central hole 4c of the storage case 4.

  Furthermore, the accommodation case 4 according to the present embodiment has a side accommodation space on the side (in the left and right direction in FIG. 3) of the head portion Ba of the mounting bolt B. The movable contact 5, the terminal plates 7a, 7b) and the seal member S1 are disposed. As a result, the housing case 4 becomes wider (that is, the dimension in the left-right direction in FIG. 3 is larger by the side housing space) by at least the side housing space, so the diameter of the integral member 3 is relatively increased. When the side stand T swings, the rotation member 2 can be rotated at a larger rotation angle to contribute to accuracy improvement by forming the locking portion 3a at the edge thereof.

  According to the above embodiment, the rotary member 2 is formed with the locking portion 3a which can be locked to the side stand T, and the tightening portion 3b which receives the tightening force of the mounting bolt B by inserting the mounting bolt B. Since the integral member 3 is attached, torque and the tightening force of the mounting bolt B applied with the swinging of the side stand T can be reliably received, and improvement in assembling workability and reduction in the number of parts are achieved. Can.

  Further, since the integral member 3 according to the present embodiment is formed by pressing the metal plate to form the locking portion 3a and the tightening portion 3b, the torque and the mounting bolt applied with the swing of the side stand T The tightening force of B can be received more reliably. Furthermore, since the rotation member 2 which concerns on this embodiment fixes the integral member 3 by insert molding, it can fix the integral member 3 with respect to the rotation member 2 more firmly.

  In addition, according to the above embodiment, since the head Ba of the mounting bolt B is located in the housing case 4, the head Ba of the mounting bolt B can be prevented from protruding from the housing case 4. Interference of a side stand spring L or the like for holding the side stand T in the stand position or the storage position can be prevented, and the degree of freedom in layout can be improved. That is, when the side stand T pivots between the stand position (see FIG. 7) and the storage position (see FIG. 8), a part of the side stand spring L passes above the attachment position of the attachment bolt B, but the attachment bolt Since the head Ba of B is located in the housing case 4, interference of the side stand spring L with the head Ba of the mounting bolt B can be surely prevented.

  Further, the accommodation case 4 according to the present embodiment has a side accommodation space on the side of the head portion Ba of the mounting bolt B, and the position detection means (the movable contact 5 and the terminal boards 7a and 7b) are included in the accommodation space. Since it arrange | positioned, the side accommodation space formed in the storage case 4 can be used effectively. Furthermore, according to the present embodiment, the side housing space is provided with the seal member S1 for sealing the position where the position detecting means (the movable contact 5 and the terminal plates 7a and 7b) is provided. While being able to utilize the formed side accommodation space still more effectively, the seal of a position detection means can be performed reliably.

  In particular, since the side wall portion 2a that covers the side of the head portion Ba of the mounting bolt B is formed, the rotary member 2 according to the present embodiment can cover the head portion Ba of the mounting bolt B more reliably. At the same time, the space where the head Ba of the mounting bolt B is located and the other space in the housing case 4 can be reliably defined. In the present embodiment, the side wall 2 a of the mounting bolt B covers the side of the head Ba of the mounting bolt B, but the side wall 2 a is not formed. The head Ba of the mounting bolt B may be located inside.

  As mentioned above, although this embodiment was described, the present invention is not limited to this, for example, it replaces with movable contact 5 and terminal boards 7a and 7b which constitute position detection means, for example, a rotating member 2 of magnet and Hall IC. It is good also as position detection means of other forms, such as what detects rotation. Further, in the present embodiment, the head portion Ba of the mounting bolt B is configured to be positioned within the housing case 4, but the head portion Ba of the mounting bolt B protrudes outside the housing case 4 It is also good.
