  Thereby, as shown in FIGS. 1-3 and FIG. 5, the position control part 14 is the pedal main body 2 of the location located in the spring member 11 arrange | positioned on the chassis main body part 5, and the opening part 13 of the cover case 4. As shown in FIG. It is comprised so that it may be arrange | positioned in the pedal case 1 in the state straddled. On the lower surface of the upper plate portion 14 c in the position restricting portion 14, an upper limit stopper portion 15 such as felt or rubber with which the upper surface of the pedal body 2 abuts so as to be able to come into contact with and separate from is provided.

  On the other hand, the pedal body 2 is, as shown in FIGS. 1, 2, and 4, the width of the tip 2 a side (left side in FIG. 4A) (that is, the length in the direction orthogonal to the longitudinal direction of the pedal body 2). And the rear end 2b side (the right side in FIG. 4 (a)) has a narrow width (the length in the direction perpendicular to the longitudinal direction of the pedal body 2) and has a substantially insulator shape. 2c is formed.

  In this case, as shown in FIGS. 4A and 4B, the rear end portion 2b of the pedal body 2 is formed so that the downward wall 2c protrudes rearward (right side in FIG. 4A). . As shown in FIG. 2, the pedal body 2 is inserted into the cover case 4 through the opening 13 of the cover case 4, and the inserted rear end 2 b is a pedal on the chassis body 5. It is configured to be attached to the support portion 8 by a rotary shaft 16 so as to be rotatable in the vertical direction.

  In addition, as shown in FIG. 2, the pedal body 2 has a portion inserted into the cover case 4 through the opening 13 of the cover case 4 is pushed up by the spring member 11 on the chassis body 5 and is positioned. The upper limit position is regulated by abutting the upper limit stopper portion 15 of 14 from below.

  Further, as shown in FIG. 6, the pedal body 2 is pushed down against the spring force of the spring member 11 when the distal end portion 2 a protruding outside the cover case 4 through the opening 13 of the cover case 4 is pressed. The pedal support portion 8 provided on the chassis main body 5 is configured to rotate counterclockwise about the rotation shaft 16 of the pedal support portion 8.

A switch pressing portion 9 is provided for pressing. As a result, as shown in FIG. 6, when the pedal body 2 rotates counterclockwise around the rotation shaft 16 of the pedal support portion 8, the switch pressing portion 9 of the pedal body 2 becomes the dome-shaped rubber of the switch portion 10. The bulging portion 10b is pushed down to be elastically deformed, and the movable contact in the elastically deformed rubber bulging portion 10b is brought into contact with the fixed contact of the switch substrate 10a to output a switch signal.

  Further, as shown in FIG. 6, the pedal body 2 rotates counterclockwise around the rotating shaft 16 of the pedal support portion 8 and pushes down the dome-shaped rubber bulging portion 10b of the switch portion 10 to elastically deform. Then, the lower limit stopper portion 7 provided on the front end portion (left end portion in FIG. 2) of the extension portion 6 extending from the chassis main body portion 5 to the front side (left side in FIG. 4) is contacted from above. The lower limit position is restricted.

  By the way, a gap S is generated in the opening 13 of the cover case 4 from which the pedal body 2 protrudes from the inside of the pedal case 1 according to the depression operation of the pedal body 2 as shown in FIG. In this gap S, as shown in FIGS. 1, 2, and 6, foreign matter for preventing foreign matter from being inserted between the upper portion of the opening 13 of the cover case 4 and the upper surface of the pedal body 2. An insertion prevention part 17 is arranged.

  As shown in FIG. 1, FIG. 3, and FIG. 5, the foreign matter insertion preventing portion 17 is formed by bending a belt-like plate, and has a flat plate-like attachment portion 17a and a tip portion of the flat plate-like attachment portion 17a. And a flat plate-shaped insertion preventing portion 17b bent downward. The foreign matter insertion preventing portion 17 has a flat plate-like mounting portion 17 a attached to the position restricting portion 14 of the pedal case 1, and a flat plate-like insertion preventing portion 17 b bent downward is provided on the cover case 4. The pedal body 2 at a location corresponding to the opening 13 is configured to be inserted into a slit-shaped insertion hole 18a provided in an elongated shape in a direction perpendicular to the longitudinal direction.

  That is, as shown in FIGS. 2 and 6, the foreign matter insertion preventing portion 17 has a flat mounting portion 17 a on the upper plate portion 14 c of the position restricting portion 14 provided on the chassis main body portion 5 of the pedal case 1. The flat plate-shaped insertion preventing portion 17b is suspended from the upper portion in the opening 13 of the cover case 4, and the lower portion of the suspended insertion preventing portion 17b is vertically inserted into the slit-shaped insertion hole 18a of the pedal body 2. The insertion preventing portion 17b is configured to move relatively vertically in the insertion hole 18a in accordance with the vertical movement of the pedal body 2 while maintaining this state.

Next, the operation of the pedal device according to the first embodiment will be described.
First, in a normal state where the pedal body 2 is not depressed, the pedal body 2 is pushed up by the spring force of the spring member 11 as shown in FIG. The pedal body 2 rotates clockwise around the rotation shaft 16, and the upper surface of the pedal body 2 comes into contact with the upper limit stopper portion 15 of the position restricting portion 14 provided on the chassis body portion 5 from below. The pedal body 2 is restricted to the upper limit position.

  In this state, as shown in FIG. 2, the pedal body 2 is in a substantially horizontal state, and the distal end portion 2 a of the pedal body 2 is provided with the lower limit stopper portion 7 provided at the distal end portion of the extension portion 6 of the pedal case 1. Separated upward. At this time, the gap S between the upper part of the opening 13 of the cover case 4 and the upper surface of the pedal body 2 is the narrowest. For this reason, the foreign object insertion preventing portion 17 has the flat plate-shaped insertion preventing portion 17 b inserted deeply into the slit-like insertion hole 18 a of the pedal body 2.

  At this time, as shown in FIG. 2, the switch pressing portion 9 of the pedal body 2 located in the cover case 4 is separated above the switch portion 10. For this reason, the dome-shaped rubber bulging portion 10b of the switch portion 10 is elastically restored, and the movable contact in the rubber bulging portion 10b is separated from the fixed contact of the switch substrate 10a and is in the off state.

  In this state, when the front end portion 2a of the pedal body 2 positioned outside the cover case 4 is stepped on against the spring force of the spring member 11, the pedal body 2 is moved to the chassis body portion as shown in FIG. 5 rotates counterclockwise around the rotation shaft 16 of the pedal support 8. Then, the front end portion 2a of the pedal body 2 is lowered, and accordingly, the gap S generated between the upper portion of the opening 13 of the cover case 4 and the upper surface of the pedal body 2 is gradually widened. For this reason, the foreign object insertion preventing portion 17 is relatively moved so that the flat plate-like insertion preventing portion 17 b faces upward in the slit-like insertion hole 18 a of the pedal body 2.

  And when the front-end | tip part 2a of the pedal main body 2 is further stepped on, when the pedal main body 2 further rotates counterclockwise centering on the rotating shaft 16 of the pedal support part 8 of the chassis main body part 5, as shown in FIG. The switch pressing portion 9 of the pedal body 2 located in the cover case 4 presses the switch portion 10 and elastically deforms the dome-shaped rubber bulging portion 10 b in the switch portion 10. Thereby, the switch part 10 contacts the fixed contact of the switch board | substrate 10a, and the movable contact in the rubber bulging part 10b contacts, and outputs a switch signal.

  Thereafter, when the distal end portion 2a of the pedal body 2 is further stepped on, the lower end stopper portion 7 provided at the distal end portion of the extension portion 6 of the pedal case 1 is provided with the distal end portion 2a of the pedal body 2 as shown in FIG. The lower limit position is restricted by abutting from above. In this state, the gap S generated between the upper part of the opening 13 of the cover case 4 and the upper surface of the pedal body 2 is the widest.

  For this reason, as shown in FIG. 6, the foreign object insertion preventing portion 17 has its flat insertion preventing portion 17 b relatively moved upward in the slit-like insertion hole 18 a of the pedal body 2. However, at this time, as shown in FIG. 6, the flat plate-shaped insertion preventing portion 17 b does not slip upward from the slit-shaped insertion hole 18 a of the pedal body 2.

  In this state, even if the foot that is stepping on the tip 2a of the pedal body 2 moves toward the gap S between the upper part of the opening 13 of the cover case 4 and the upper surface of the pedal body 2, The toe of the foot touches the insertion preventing part 17 b of the foreign object insertion preventing part 17. Thereby, it is possible to prevent the tip of a toe from being inserted into the gap S generated between the upper portion of the opening 13 of the cover case 4 and the upper surface of the pedal body 2. For this reason, when the pedal body 2 is pushed up by the spring force of the spring member 11 and returns to the initial position, the toe of the foot that is stepped on is between the upper portion of the opening 13 of the cover case 4 and the upper surface of the pedal body 2. Is not caught in the gap S.

  As described above, according to the pedal device of the first embodiment, the rear end 2b of the pedal body 2 is vertically moved in the pedal case 1 in a state where the front end 2a of the pedal body 2 protrudes from the inside of the pedal case 1 to the outside. In the pedal device mounted so as to be rotatable in the direction, the pedal body 2 protrudes from the inside of the pedal case 1 toward the outside, and between the pedal case 1 and the pedal body 2 when the pedal body 2 is depressed. A foreign matter insertion preventing portion 17 for preventing foreign matter insertion is provided at a position corresponding to the generated gap S, and thus a foreign matter such as a toe of a foot is generated between the pedal case 1 and the pedal body 2. Inserting into S can be prevented reliably.

  That is, in the pedal device according to the first embodiment, the pedal case 1 and the pedal body 2 are located where the pedal body 2 protrudes from the inside of the pedal case 1 toward the outside when the distal end portion 2a of the pedal body 2 is stepped on. Even if a gap S is generated between the pedal case 1 and the foreign matter insertion preventing portion 17, foreign matter such as a toe can be reliably prevented from being inserted into the gap S generated between the pedal case 1 and the pedal body 2. . Thereby, there is no fear of injury by pinching the toes of the toes in the gap S between the pedal case 1 and the pedal body 2, and a highly safe product can be provided.

  In this case, the foreign matter insertion preventing portion 17 is provided at a position of the pedal case 1 located between the pedal case 1 and the pedal body 2, and the pedal body 2 is moved up and down in an insertion hole 18 a provided in the pedal body 2. Therefore, when the pedal body 2 is not depressed, the pedal body 2 is restricted to the upper limit position, and between the pedal case 1 and the pedal body 2. The generated gap S is the narrowest, and the foreign matter insertion preventing portion 17 is inserted deepest into the insertion hole 18a of the pedal body 2, so that the foreign matter insertion preventing portion 17 can be hidden from view outside the pedal case 1, Thereby, what is preferable in terms of appearance and design can be provided.

  Further, the foreign matter insertion preventing portion 17 has a gap S generated between the pedal case 1 and the pedal body 2 when the pedal body 2 is depressed. The foreign matter insertion preventing portion 17 moves without slipping out upward from the slit-like insertion hole 18a of the pedal body 2 and closes the gap S generated between the pedal case 1 and the pedal body 2. Thus, the foreign matter insertion preventing portion 17 can reliably prevent foreign matters such as the toes of the foot from being inserted into the gap S generated between the pedal case 1 and the pedal body 2.

  In this case, the foreign matter insertion preventing portion 17 is provided in the pedal case 1 and provided in the position restricting portion 14 for restricting the upper limit position of the pedal body 2, so that the position restricting portion 14 is attached to the pedal case 1. At the same time, the foreign object insertion preventing portion 17 can be disposed in the gap S generated between the pedal case 1 and the pedal body 2. For this reason, the number of parts at the time of assembly can be reduced, and the assembly work can be improved.

  In the first embodiment described above, the foreign matter insertion preventing portion 17 has a flat mounting portion 17a, and a flat insertion preventing portion 17b that is bent toward the lower end of the flat mounting portion 17a. However, the present invention is not limited to this. For example, as in the first modified example shown in FIGS. 7 and 8, the foreign matter insertion prevention unit 20 has a configuration in which a rod-shaped member such as a round bar is bent. There may be.

  That is, as shown in FIGS. 7 and 8, the foreign matter insertion preventing portion 20 of the first modified example has a rod-like attachment portion 20a attached to the position restricting portion 14 and a tip portion of the attachment portion 20a on the lower side. And a rod-shaped insertion preventing portion 20b bent toward the inside, and the insertion preventing portion 20b is inserted into the pedal body 2 so as to be movable in the vertical direction into an elliptical insertion hole 18b slightly longer along the longitudinal direction thereof. What is necessary is just to comprise. Even if comprised in this way, there exists an effect similar to Embodiment 1. FIG.

  Further, in the above-described first embodiment, the case where the foreign matter insertion preventing portion 17 is provided in the position restricting portion 14 that restricts the upper limit position of the pedal body 2 is described. As shown in the second modification shown in FIG. 2, the foreign matter insertion preventing portion 21 may be directly attached to the pedal case 1 at a location corresponding to the gap S generated between the pedal case 1 and the pedal body 2.

  That is, the foreign matter insertion preventing portion 21 of the second modified example is formed in a flat plate shape as shown in FIGS. 9 and 10, and the opening portion 13 provided in the cover case 4 of the pedal case 1. It is provided in a state where it is suspended from the upper part on the inner surface, and is inserted into the pedal body 2 in a slit-like insertion hole 18a formed in an elongated shape along a direction perpendicular to the longitudinal direction of the pedal body 2 so as to be movable in the vertical direction. What is necessary is just to comprise. Even if comprised in this way, there exists an effect similar to Embodiment 1. FIG.
