The case 31 has an opening on the left side, and a cover 32 is attached to the left side of the case 31 in the housing 30 as shown in FIG. The housing 30 is configured as a left wall where the cover 32 faces the right wall 37.

  As shown in FIG. 2, an opening 36 </ b> A is provided in the upper wall 36 of the case 31, that is, the upper wall of the housing 30. The organ-type vehicle pedal device is provided with a rod 40 penetrating through the opening 36A. The rod 40 has an upper end extending upward from the housing 30 connected to the pad 20 and a lower end located inside the housing 30. An arm 50 is provided at the lower end of the rod 40. The arm 50 is bent at the lower end of the rod 40 in a direction intersecting with the extending direction of the rod 40, and bent upward from the first bent portion 51 at the front end of the first bent portion 51. And a second bent portion 52 extending along the front wall 34. A magnetic body 53 such as a magnet is embedded in the first bent portion 51. A pedestal 60 is fixed to the lower wall 33 of the housing 30. A magnetic sensor 61 is embedded in the pedestal 60. The magnetic sensor 61 outputs a signal corresponding to the distance between the first bent portion 51 and the magnetic body 53. A compressed spring 70 is disposed between the lower wall 33 and the first bent portion 51 of the arm 50. The spring 70 biases the arm 50 upward, and functions as a biasing member that biases the upper end portion of the pad 20 via the rod 40 in a rotating direction away from the housing 30.

  As shown in FIG. 3, the arm 50 is provided with a stopper 54. The stopper 54 is provided on the facing surface 52 </ b> A that faces the front wall 34 of the housing 30 on the peripheral surface of the second bent portion 52, and protrudes toward the housing 30. The stopper 54 is positioned at the lower end of the arm 50 and has a substantially triangular shape when viewed from the front wall 34 side. The stopper 54 has a pair of outer surfaces 54A extending in the vertical direction, and the outer surfaces 54A are closer to each other toward the upper side and are connected at their upper ends. A pair of opposing walls 55 are disposed in the second bent portion 52 with the stopper 54 interposed therebetween. Each opposing wall 55 protrudes from the opposing surface 52A to the front wall 34 side by substantially the same amount as the protruding amount of the stopper 54 from the opposing surface 52A, and continuously extends in the vertical direction from the upper end to the lower end of the second bent portion 52. ing.

  As shown in FIG. 3, the second bent portion 52 of the arm 50 is provided with an extending wall 56 extending upward from the second bent portion 52. The extending wall 56 refers to a portion continuously extending from the second bent portion 52 above the height position where the stopper 54 of the second bent portion 52 is provided. A pair of projecting walls 57 extending in the vertical direction are provided at both ends of the side wall 56A on the front wall 34 side of the extending wall 56. The pair of projecting walls 57 has lower ends connected to upper ends of the pair of opposing walls 55, and the projecting walls 57 and the opposing walls 55 constitute a pair of walls that are continuous in the vertical direction.

  As shown in FIGS. 4 and 5, the housing 30 is provided with a restraining portion 39 protruding inside. The restraining portion 39 is provided on the inner surface of the front wall 34 and is in a positional relationship facing the facing surface 52A on which the stopper 54 of the second bent portion 52 is provided. The length of the restraining portion 39 in the left-right direction is slightly shorter than the maximum length of the stopper 54 in the left-right direction. As shown in FIG. 5, the restraining portion 39 is disposed so as to be above the stopper 54, and the protruding length from the inner surface of the housing 30 is set so as to reach the facing region by the pair of facing walls 55. . As shown in FIG. 4, the restraining portion 39 has a substantially rectangular parallelepiped shape and has a pair of cutout surfaces 39 </ b> A cut out from the lower end thereof. The cut-out surface 39A extends in the vertical direction, and approaches the upper side and is connected to the upper end. The inclination angle of the pair of notch surfaces 39A is set to be substantially the same as the inclination angle of the outer surface 54A of the stopper 54. Therefore, the upper end of the stopper 54 can come into contact with the upper end of the notch surface 39A. When the upper end of the stopper 54 is in contact with the upper end of the notch surface 39A as shown in FIG. Is disposed between the cut-out surfaces 39A of the stop portion 39, and the lower end portion of the stopper 54 protrudes downward from the stop portion 39.

The operation of the organ-type vehicle pedal device will be described.
As shown in FIG. 2, when the driver depresses the pad 20, the pad 20 is rotated away from the housing 30 by the urging force of the spring 70, that is, upward. Accordingly, the stopper 54 is displaced upward and comes into contact with the restraining portion 39 of the housing 30 provided above the stopper 54. The lower end portion of the restraining portion 39 is notched as described above, and the upper end of the stopper 54 comes into contact with the upper end of the notch surface 39A of the restraining portion 39, and the stopper 54 is locked to the restraining portion 39. Thereby, the rotation of the pad 20 by the urging force of the spring 70 is stopped at a predetermined position.

  When the driver steps on the pad 20, the pad 20 rotates in the rotating direction approaching the housing 30 against the biasing force of the spring 70, that is, in the downward direction, and the stopper 54 and the stopper 39 are separated from each other. As the driver's stepping force increases, the first bent portion 51 of the arm 50 connected to the pad 20 moves downward and approaches the lower wall 33 of the housing 30. As shown in FIG. 6, when the first bent portion 51 comes into contact with the pedestal 60, the pad 20 is further prevented from rotating. Since a signal corresponding to the distance from the magnetic body 53 is output from the magnetic sensor 61, the vehicle control device, for example, based on the signal input from the magnetic sensor 61, the amount of rotation of the pad 20, that is, the vehicle pedal device. The operation amount is detected, and various controls in the vehicle are executed.

With reference to FIG.7 and FIG.8, the effect of this embodiment is demonstrated.
(1) In the organ-type vehicle pedal device, foreign matter may enter the housing 30 through the opening 36 </ b> A of the housing 30. If a foreign object enters the inside of the housing 30 through the opening 36A, it is expected to move downward due to gravity as shown by a solid line in FIG. In the present embodiment, since the arm 50 is provided at the lower end of the rod 40, it is expected that the foreign matter that has entered through the opening 36A enters the vicinity of the arm 50. However, since the stopper 54 is provided not on the peripheral surface of the first bent portion 51 of the arm 50 but on the opposing surface 52A of the second bent portion 52 further away from the rod 40, the stopper 54 has moved downward from the opening 36A. Foreign matter is prevented from entering directly between the stopper 54 and the front wall 34 of the housing 30. Thereby, it is possible to prevent foreign matter that has entered the housing 30 through the opening 36 </ b> A from being sandwiched between the stopper 54 and the housing 30.

  (2) The second bent portion 52 of the arm 50 is provided with a pair of opposing walls 55 and extending walls 56, and the stopper 54 is surrounded by the opposing walls 55 and extending walls 56. As a result, the space from the opening 36A of the housing 30 to the stopper 54 becomes complicated, and as shown by a one-dot chain line in FIG. 7, the second bent unless the foreign matter goes around the pair of opposing walls 55 and the extending walls 56. It cannot enter between the portion 52 and the front wall 34. Therefore, entry of foreign matter between the stopper 54 and the front wall 34 of the housing 30 can be more suitably suppressed.

  (3) Further, the stopper 54 has a triangular shape when viewed from the front wall 34 side, and the outer surface 54A of the stopper 54 has an oblique shape. As a result, as shown by a solid line in FIG. 8, even if foreign matter enters between the second bent portion 52 and the front wall 34, the foreign matter moves downward along the outer surface 54A of the stopper 54, and the stopper It is possible to prevent foreign matter from adhering to 54.

In addition, the said embodiment can be changed and implemented as follows.
-Although the 2nd bending part 52 is provided so that it may extend along the front wall 34, it is not limited to this. For example, the upper side of the second bent portion 52 may be provided so as to be inclined toward the front wall 34 side.

The second bent portion 52 may be bent upward at a position closer to the rod 40 than the front end of the first bent portion 51.
-Although the example which bent the 1st bending part 51 to the front wall 34 side of the housing 30 was shown, if the direction in which the 1st bending part 51 bends is a direction which cross | intersects the extending direction of the rod 40, it will change arbitrarily Is possible. For example, the first bent portion 51 may be bent toward the right wall 37 side or bent toward the rear wall 35 side.

The first bent portion 51 may be bent at a position above the lower end of the rod 40.
-Although the housing 30 which provided the opening in the left side part of the case 31 and attached the cover 32 to this left side part was illustrated, the structure of the housing 30 is not restricted to such a thing. For example, a configuration in which an opening is provided in the front end portion of the case 31 and the cover 32 is attached to the front end portion may be employed. A housing in which the cover 32 and the case 31 are integrated may be employed. Further, the lower wall 33 may be omitted, and a configuration in which the lower end of each side wall of the housing 30 is directly attached to the plate body 11 of the support plate 10 may be employed.

  The cross-sectional shape of the stopper 54 is not limited to a substantially triangular shape. For example, a trapezoidal shape, a rhombus shape, a substantially oval shape, or a substantially round shape may be used so as to have a pair of outer surfaces. Further, the stopper 54 is configured to protrude in the same direction as the direction in which the first bent portion 51 extends on the facing surface 52A of the second bent portion 52, but if the stopper 54 contacts the restraining portion 39 of the housing 30, The protruding direction is not particularly limited.

  The inclination angle of the cutout surface 39A of the stop portion 39 may be different from the inclination angle of the outer surface 54A of the stopper 54. Moreover, the lower end of the stop part 39 does not need to be notched. Moreover, the shape of the stop part 39 is not restricted to a substantially rectangular parallelepiped. For example, a cube or a cylinder may be used. In short, any structure that can abut against the stopper 54 and stop the rotation of the pad 20 may be used.

  -The opposing wall 55 and the protrusion wall 57 do not need to be provided continuously. Further, the protruding wall 57 may be omitted. Further, the vertical length of the opposing wall 55 can be arbitrarily set as long as it is longer than the vertical length of the stopper 54 and can surround the side of the stopper 54. Further, the opposing wall 55 may be disposed so as to be inclined so that the distance between both of them becomes shorter toward the upper side. Further, the protruding amount of the facing wall 55 from the facing surface 52A can be arbitrarily changed. Further, the opposing wall 55 may be disposed so as to be inclined so that the distal ends thereof approach each other in the protruding direction from the opposing surface 52A.

  The extending direction of the extending wall 56 does not need to be the same as the extending direction of the second bent portion 52. For example, the extending direction of the extending wall 56 is inclined so that the upper wall is inclined toward the front wall 34 side of the housing 30. You may make it differ from the direction where the 2nd bending part 52 is extended.

  -Arrangement | positioning of an urging member is not restricted to arrangement | positioning of the spring 70 mentioned above. For example, a compression spring is disposed between the upper wall 36 of the housing 30 and the pad 20, or a spring is disposed between the plate body 11 of the support plate 10 and the pad 20 outside the housing 30. This may be used as the biasing member. Moreover, you may employ | adopt other elastic members as a biasing member instead of a spring as a form of a biasing member.
