A lock mechanism 13 that locks the pedal arm 20 and releases the lock of the pedal arm 20 by being depressed again is provided.

  As shown in FIG. 1, the pedal arm 20 is provided with an inner cable 42 of the brake cable 40 in which the distal end of the outer tube 41 is fixed to the mounting portion 12 a of the bracket 12 along the upper peripheral edge of the pedal arm 20. The tip is fixed to the cable attachment portion 20 a of the pedal arm 20. As a result, when the driver (operator) steps on the pedal pad 30, the pedal arm 20 is rotated counterclockwise in FIG. 1 and pulls the inner cable 42 to operate a wheel brake mechanism (not shown). Although the pedal arm 20 is urged clockwise in FIG. 1 by a return spring (not shown), when the brake mechanism is not operated, the pedal arm 20 abuts against a stopper 12b provided on the bracket 12 to restrict clockwise rotation. Is done.

  The lower part of the pedal arm 20 is formed in a U-shaped cross section, and the upper plate 20b, the side plate 20c, and the lower plate 20d are integrally connected. Thus, the pedal arm 20 can be manufactured by pressing a sheet metal, and can be manufactured easily and at low cost. Moreover, since it is substantially U-shaped, it is possible to obtain sufficient rigidity against the force of stepping on the foot and to reduce the weight.

  An attachment portion (pedal pad attachment portion) 21 is provided at the lower end portion of the pedal arm 20. The attachment portion 21 is formed in a substantially square shape and a plate shape, and one side other than the upper end of the attachment portion 21, that is, the lower side and the left and right sides are connected to the lower end portion of the pedal arm 20. In the present embodiment, the right side of the attachment portion 21 is integrally connected to the upper edge of the lower end of the side plate 20 c of the pedal arm 20. The attachment portion 21 is also integrally connected to the upper plate 20b. That is, the attachment portion 21 extends from the upper end of the lower side surface of the pedal arm 20 in the left direction (see FIG. 3). Accordingly, the lower end portion of the pedal arm 20 is also formed in a U-shaped cross section.

  A pedal pad 30 is attached to the attachment portion 21. The pedal pad 30 is used to place a driver's foot when the parking brake pedal 10 is depressed by an operator. The pedal pad 30 is formed of a resin material having elasticity (for example, an elastomer including synthetic rubber) to prevent the foot from sliding on the pedal pad 30 and to improve the feel when the pedal pad 30 is stepped on. As shown mainly in FIGS. 1, 2, and 4, the pedal pad 30 is formed in a stepped portion 31 that is formed in a plate shape that covers the entire stepped surface 21 a of the mounting portion 21, and is formed in a bag shape on the stepped portion 31. And a fitting portion 32 that is fitted on the attachment portion 21. The stepping portion 31 and the fitting portion 32 are integrally formed of a resin material.

  As shown in FIG. 2, the stepping portion 31 does not protrude from the side surface of the side plate 20 c that is the side surface of the lower end portion of the pedal arm 20. Thereby, it is possible to prevent the pedal pad 30 from coming off by preventing the operator's foot from being caught on the pedal pad 30 from the back side of the pedal. The fitting portion 32 has an open end into which the attachment portion 21 is inserted, a closed end (left end) provided on one side opposite to the open end, and two closed portions provided on both sides (upper and lower sides) of the open end. It has ends (upper and lower ends). The closed end (upper end) of the fitting portion 32 is set to a length that is more than half of the left-right width of the stepping portion 31, and the closed end (lower end) of the fitting portion 32 is approximately the length of the left-right width of the stepping portion 31. It is set to be the same.

  The fitting part 32 of the pedal pad 30 is fitted from the left side (the extending direction of the attachment part 21) opposite to the right side which is one side of the attachment part 21 of the pedal arm 20 (fixed end side of the attachment part 21). Thus, the pedal pad 30 is attached to the pedal arm 20. When the fitting portion 32 is fitted, the fitting portion 32 is fitted to the fitting position (position shown in FIG. 2) where the inside of the left end that is the closed end of the fitting portion 32 contacts the left end that is the tip of the mounting portion 21. Thereby, the pedal pad 30 is positioned and fixed at the fitting position.

  Further, as shown in FIGS. 1, 2, and 3, an engagement hole 22 that is an engagement recess is provided in the stepping surface 21 a of the attachment portion 21 of the pedal arm 20. On the back surface of the stepped portion 31 of the pedal pad 30 that abuts on the stepped surface 21a, an engaging convex portion 33 is provided at a portion corresponding to the engaging hole 22, as shown in FIGS. . A direction in which the engagement portion 22 of the pedal pad 30 engaged with the engagement hole 22 and the engagement convex portion 33 and engaged with the attachment portion 21 of the pedal arm 20 deviates from the above-described engagement position (leftward in FIG. 2). ) Is restricted to move to. Moreover, although the engagement hole 22 is a hole which penetrates the attachment part 21, it may be a recessed part instead of such a hole.

  As shown in FIG. 4, the engagement convex portion 33 is formed in a cross-sectional wedge shape having an inclined surface 33 a and a vertical surface 33 b connected to the inclined surface 33 a, and the pointed end is a fitting portion 32 (pedal pad 30). Is disposed so as to face the fitting direction (right direction in FIGS. 2 to 4). Thus, when the fitting portion 32 is fitted into the attachment portion 21, when the inclined surface 33a comes into contact with the left end of the attachment portion 21, the engagement convex portion 33 and the stepping portion 31 are elastically deformed and smoothly move to the fitting position. That is, the engaging convex portion 33 can smoothly move to the engaging position (the position where the engaging convex portion 33 engages with the engaging hole 22). When the fitting portion 32 reaches the fitting position, the engagement convex portion 33 fits into the engagement hole 22 and engages, and the elastic deformation of the stepping portion 31 is released. Can be definitely obtained. The vertical surface 33 b of the engagement convex portion 33 is in contact with and engaged with the inner peripheral surface of the engagement hole 22. Thereby, the fitting part 32 is prevented from coming off from the attachment part 21.

  Moreover, it is preferable that the engaging convex part 33 is integrally molded with a resin material having higher rigidity than the other parts of the pedal pad 30. Thereby, since the engagement convex part 33 becomes difficult to deform | transform, the engagement feeling at the time of engagement can be obtained more reliably, and the engagement of the engagement convex part 33 and the engagement hole 22 is strengthened more firmly. can do.

  A portion corresponding to the engagement hole 22 on the back surface of the step portion 31 of the pedal pad 30 provided with an engagement recess (engagement hole 22) on the step surface 21a of the attachment portion 21 of the pedal arm 20 and contacting the step surface 21a. However, conversely, the engagement convex portion is provided on the stepping surface 21a of the attachment portion 21 of the pedal arm 20, and the back surface of the stepping portion 31 of the pedal pad 30 that contacts the stepping surface 21a. You may make it provide an engagement recessed part in the site | part corresponding to this engagement convex part. Even in this case, the engagement recess 32 and the engagement protrusion can be engaged and the fitting portion 32 fitted to the attachment portion 21 can be restricted from moving away from the fitting position.

  The process of assembling the pedal pad 30 to the pedal arm 20 in the automobile pedal configured as described above will be described. The opening of the fitting portion 32 of the pedal pad 30 is inserted from the left side of the attachment portion 21 of the pedal arm 20. At this time, when the inclined surface 33a of the engaging convex portion 33 of the pedal pad 30 contacts the left end of the mounting portion 21, the engaging convex portion 33 and the stepping portion 31 are smoothly moved toward the fitting position while being elastically deformed. That is, the engagement convex portion 33 is smoothly moved to the engagement position (position where the engagement convex portion 33 engages with the engagement hole 22). When the fitting portion 32 reaches the fitting position, the engagement convex portion 33 is fitted into the engagement hole 22 and engaged, and the pedal pad 30 is attached to the pedal arm 20 (state of FIG. 2).

  At this time, the closed end (upper end) of the fitting portion 32 is set to a length that is more than half the left-right width of the stepping portion 31, and the closed end (lower end) of the fitting portion 32 is substantially the left-right width of the stepping portion 31. Therefore, the fitting portion 32 is externally fitted to more than half of the left side of the mounting portion 21. That is, the stepping surface 21 a and the back surface of the attachment portion 21 abut on the back surface (inner wall surface) of the stepping portion 31 and the inner wall surface of the fitting portion 32, and the upper and lower ends and the left end of the attachment portion 21 are closed ends of the fitting portion 32. It is in contact with the inner wall surfaces of the upper and lower ends and the closed end (left end).

  As can be understood from the above description, in this embodiment, the fitting portion 32 of the pedal pad 30 is attached to the attachment portion 21 in which the right end which is one side other than the upper end is connected to the lower end portion of the pedal arm 20. The pedal pad 30 is attached to the pedal arm 20 by being inserted from the left side opposite to the right end which is one side of the portion 21. Thereby, the fitting part 32 of the pedal pad 30 is externally fitted to the attachment part 21 of the pedal arm 20 from the left side that is not in the downward direction. At this time, the fitting portion 32 is externally fitted to more than half of the left side of the attachment portion 21. Therefore, when the operator steps on the pedal pad 30 and a downward load is applied to the lower end portion of the pedal pad 30, the fitting portion 32 does not move even if a force that lifts the upper end portion acts on the lever principle. Since the fitting part 21 is externally fitted, it is possible to prevent the pedal pad from being detached from the upper end part of the attaching part 21. Further, when a torsional load due to depression is applied to the pedal pad 30, the fitting portion 32 is externally fitted to the attachment portion 21 even if the pedal pad 30 is twisted. It can be prevented from coming off.

  Further, since the pedal pad 30 is inserted and fixed to the fitting position where the inner side of the closed end (left end) of the fitting portion 32 contacts the tip (left end) of the mounting portion 21, the pedal pad 30 is securely and securely attached. It can be positioned and fixed easily.

  In addition, an engagement recess is provided in one of the pedal arm 20 and the pedal pad 30, and an engagement protrusion is provided in the other portion corresponding to the engagement recess, and the engagement recess and the engagement protrusion are engaged. Thus, the movement of the fitting portion 32 of the pedal pad 30 fitted to the attachment portion 21 in the direction away from the fitting position is restricted, so that the pedal pad 30 can be prevented from coming off with a simple configuration.

  In addition, an engagement recess is provided on one of the stepping surface 21a of the attachment portion 21 of the pedal arm 20 and the back surface of the stepping portion 31 of the pedal pad 30 that is in contact with the stepping surface 21a, and the other corresponding to the engagement recess. Since the engagement convex portion is provided at the site, when the operator steps on the pedal pad 30, the engagement of the engagement convex portion and the engagement concave portion is further strengthened by the stepping force of the operator. Therefore, it is possible to more reliably prevent the pedal pad 30 from coming off.

  Further, the engagement convex portion 33 is formed in a wedge shape in section having an inclined surface 33a and a vertical surface 33b connected to the inclined surface 33a, and the pointed end has a fitting direction in which the pedal pad 30 is fitted into the mounting portion 21. Since the engagement convex portion 33 engages with the engagement concave portion (engagement hole 22), the engagement convex portion 33 can be smoothly engaged, and the engagement feeling at the time of engagement can be obtained. You can definitely get it.

  Further, since the engaging convex portion 33 is integrally formed of a resin material having higher rigidity than the other portions of the pedal pad 30, it is possible to more reliably obtain an engagement feeling at the time of engagement. The engagement between the mating convex portion 33 and the engaging concave portion (engagement hole 22) can be further strengthened.

  Also. Since the pedal arm 20 is formed in a U-shaped cross section by press molding, the pedal arm 20 can be configured with high rigidity with a thin sheet metal, can be easily manufactured without trouble, and can be manufactured at low cost. The weight can be reduced.
