Description

本発明は、車体側に取り付けられるペダルブラケットに車幅方向に延びる樹脂製の支軸を介して揺動自在に支持される操作ペダルの支持構造に関するものである。   The present invention relates to a support structure for an operation pedal that is swingably supported by a pedal bracket attached to a vehicle body via a resin support shaft extending in the vehicle width direction.

車体側に取り付けられるペダルブラケットに車幅方向に延びる樹脂製の支軸を介して揺動自在に支持される操作ペダルの支持構造が従来技術として知られている。   2. Description of the Related Art Conventionally, a support structure for an operation pedal that is swingably supported by a pedal bracket attached to the vehicle body via a resin support shaft extending in the vehicle width direction is known.

例えば、特許文献１のものは、その一端側にボスが設けられたペダルアーム（操作ペダル）を、ブラケット（ペダルブラケット）に対してボスに挿通される枢支ピン（支軸）を介して揺動自在に枢支せしめる一方、ボスにはアシストスプリングを支持するスプリング取付アームが突設されたものである。そして、ボスを金属製とする一方、枢支ピンを樹脂製とし、この枢支ピンをボスに設けられたピン受穴に直接嵌挿する。   For example, in Patent Document 1, a pedal arm (operating pedal) provided with a boss on one end side thereof is swung via a pivot pin (support shaft) inserted into the boss with respect to a bracket (pedal bracket). The boss is provided with a spring mounting arm that supports the assist spring while being pivotally supported. Then, while the boss is made of metal, the pivot pin is made of resin, and the pivot pin is directly inserted into a pin receiving hole provided in the boss.

ペダルアームのブラケットへの取り付けは、まず、ボスをブラケットの一対の側板間に介装配置して、そのピン受穴を一対の側板の各ピン穴に重合させ、そして、これら重合穴に枢支ピンを、ブラケットの一方の側板側から他方の側板側に向けて挿通するとともに、この他方の側板から突出した枢支ピンの先端部にプッシュナットを取り付けることにより行う。このようにプッシュナットを取り付けることにより、枢支ピンをブラケットやペダルアームから抜け止めしている。   To attach the pedal arm to the bracket, first, the boss is interposed between the pair of side plates of the bracket, the pin receiving holes are overlapped with the pin holes of the pair of side plates, and the pivot holes are pivotally supported. The pin is inserted from one side plate side of the bracket toward the other side plate side, and a push nut is attached to the tip of the pivot pin protruding from the other side plate. By attaching the push nut in this way, the pivot pin is prevented from being detached from the bracket or the pedal arm.

しかしながら、特許文献１のものは、ペダルアームをブラケットに枢支ピンを介して支持させるのに、枢支ピンの先端部に、枢支ピンをブラケットやペダルアームから抜け止めするためのプッシュナットを取り付ける必要があるため、その作業を簡単に行うことができないという問題がある。   However, in Patent Document 1, in order to support the pedal arm on the bracket via the pivot pin, a push nut for preventing the pivot pin from coming off from the bracket or the pedal arm is provided at the tip of the pivot pin. Since it is necessary to attach, there is a problem that the work cannot be easily performed.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、車体側に取り付けられるペダルブラケットに車幅方向に延びる樹脂製の支軸を介して揺動自在に支持される操作ペダルの支持構造において、操作ペダルをペダルブラケットに支軸を介して支持させる作業を簡単に行うことにある。   The present invention has been made in view of such points, and an object of the present invention is to be swingably supported by a pedal bracket attached to the vehicle body via a resin support shaft extending in the vehicle width direction. In the support structure of the operation pedal, the operation of supporting the operation pedal on the pedal bracket via the support shaft is simply performed.

第１の発明は、ペダルブラケットに車幅方向に延びる樹脂製の支軸を介して揺動自在に支持される操作ペダルの支持構造であって、上記ペダルブラケットは、互いに車幅方向に間隔を隔てて車両前後方向に延びる第１及び第２側板を有しており、上記第１側板には、上記支軸の軸方向一端部が挿通支持される第１支持孔が形成されており、上記第２側板には、上記支軸の軸方向他端部が挿通支持される第２支持孔が形成されており、上記支軸の軸方向一端部における上記第１支持孔に支持される部分の軸方向外側部分には、上記第１支持孔を通り抜け不能な頭部が形成されており、上記支軸の軸方向他端部における上記第２支持孔に支持される部分の軸方向外側部分の外周面には、径方向外側に突起する少なくとも１つの突起部が形成されており、上記第２支持孔の周縁部には、該第２支持孔に連続しかつ上記支軸を該第２支持孔に挿通させる際に上記突起部が通り抜け可能な通り抜け孔が上記突起部に対応するように形成されており、上記支軸をその軸方向他端部側から上記第１支持孔及び上記操作ペダルに挿通させた後に、上記支軸を上記第２支持孔に挿通させるとともに上記突起部を、上記通り抜け孔を通り抜けさせ、上記突起部が上記第２支持孔の周縁部における上記通り抜け孔の形成部以外の部分に位置するように上記支軸をその軸周りに回転させることにより、上記操作ペダルが上記ペダルブラケットに上記支軸を介して支持されるように構成されていることを特徴とするものである。   A first aspect of the present invention is a support structure for an operation pedal that is swingably supported by a pedal bracket via a resin support shaft extending in the vehicle width direction. The pedal brackets are spaced from each other in the vehicle width direction. First and second side plates extending in the vehicle front-rear direction are spaced apart from each other, and the first side plate is formed with a first support hole through which one end portion in the axial direction of the support shaft is inserted and supported. The second side plate is formed with a second support hole through which the other axial end of the support shaft is inserted and supported, and a portion of the second support that is supported by the first support hole at the one axial end of the support shaft is formed. A head that cannot pass through the first support hole is formed in the axially outer portion, and an axially outer portion of a portion supported by the second support hole at the other axial end of the support shaft is formed. At least one protrusion that protrudes radially outward is formed on the outer peripheral surface. In the peripheral edge of the second support hole, a through-hole is formed in the protrusion that is continuous with the second support hole and through which the protrusion can pass when the support shaft is inserted into the second support hole. The support shaft is formed so as to correspond to the first support hole and the operation pedal from the other end in the axial direction, and then the support shaft is inserted into the second support hole. By causing the protrusion to pass through the through hole and rotating the support shaft around the axis so that the protrusion is positioned at a portion other than the through hole forming portion at the peripheral edge of the second support hole. The operation pedal is configured to be supported by the pedal bracket via the support shaft.

これによれば、支軸をその軸方向他端部側からペダルブラケットの第１側板の第１支持孔及び操作ペダルに挿通させた後に、支軸をペダルブラケットの第２側板の第２支持孔に挿通させるとともに支軸の突起部を、第２側板の通り抜け孔を通り抜けさせ、突起部が第２支持孔の周縁部における通り抜け孔の形成部以外の部分に位置するように支軸をその軸周りに回転させることにより、操作ペダルがペダルブラケットに支軸を介して支持される。このように、突起部を第２支持孔の周縁部における通り抜け孔の形成部以外の部分に位置させることにより、操作ペダルがペダルブラケットに支軸を介して支持された状態において支軸をペダルブラケットや操作ペダルから抜け止めすることができる。したがって、操作ペダルをペダルブラケットに支軸を介して支持させるのに、支軸に、支軸をペダルブラケットや操作ペダルから抜け止めするための別部材を取り付ける必要がなく、その作業を簡単に行うことができる。   According to this, after inserting the support shaft into the first support hole of the first side plate of the pedal bracket and the operation pedal from the other axial end side, the support shaft is inserted into the second support hole of the second side plate of the pedal bracket. And the protrusion of the support shaft is passed through the through hole of the second side plate, and the support shaft is moved so that the protrusion is positioned at a portion other than the formation portion of the through hole in the peripheral portion of the second support hole. By rotating around, the operation pedal is supported by the pedal bracket via the support shaft. In this way, by positioning the protruding portion at a portion other than the through-hole forming portion at the peripheral edge portion of the second support hole, the support shaft can be moved to the pedal bracket in a state where the operation pedal is supported by the pedal bracket via the support shaft. And can be secured from the operation pedal. Therefore, in order to support the operation pedal on the pedal bracket via the support shaft, it is not necessary to attach a separate member to the support shaft to prevent the support shaft from coming off from the pedal bracket or the operation pedal. be able to.

第２の発明は、上記第１の発明において、上記操作ペダルが上記ペダルブラケットに上記支軸を介して支持された状態において該支軸がその軸周りに回転するのを規制する回転規制手段を備えていることを特徴とするものである。   According to a second invention, in the first invention, a rotation restricting means for restricting the rotation of the support shaft around the shaft in a state where the operation pedal is supported by the pedal bracket via the support shaft. It is characterized by having.

これによれば、操作ペダルがペダルブラケットに支軸を介して支持された状態において支軸がその軸周りに回転するのを規制する回転規制手段を設けているので、操作ペダルがペダルブラケットに支軸を介して支持された状態において支軸がその軸周りに回転して突起部が通り抜け孔を通り抜けるのを規制することでき、操作ペダルがペダルブラケットに支軸を介して支持された状態を維持することができる。   According to this, the rotation restricting means for restricting the rotation of the support shaft around the shaft in a state where the operation pedal is supported by the pedal bracket via the support shaft is provided, so that the operation pedal is supported by the pedal bracket. When the support shaft is supported via the shaft, the support shaft can be prevented from rotating around the shaft and the protrusion passing through the hole, so that the operation pedal is supported by the pedal bracket via the support shaft. can do.

第３の発明は、上記第２の発明において、上記回転規制手段は、上記頭部の軸方向内側面に軸方向内側に突起するように形成された少なくとも１つの嵌合突起部と、上記第１側板に該嵌合突起部に対応するように形成されて上記嵌合突起部が嵌合可能な嵌合孔とを有しており、上記支軸をその軸方向他端部側から上記第１支持孔及び上記操作ペダルに挿通させた後に、上記支軸を上記第２支持孔に挿通させるとともに上記突起部を、上記通り抜け孔を通り抜けさせ、上記突起部が上記第２支持孔の周縁部における上記通り抜け孔の形成部以外の部分に位置しかつ上記嵌合突起部が上記嵌合孔に嵌合されるように上記支軸をその軸周りに回転させることにより、上記操作ペダルが上記ペダルブラケットに上記支軸を介して支持されるように構成されていることを特徴とするものである。   In a third aspect based on the second aspect, the rotation restricting means includes at least one fitting protrusion formed on the inner surface in the axial direction of the head so as to protrude inward in the axial direction. The side plate has a fitting hole that is formed so as to correspond to the fitting projection, and the fitting projection can be fitted therein. After the first support hole and the operation pedal are inserted, the support shaft is inserted into the second support hole and the protruding portion is passed through the through hole, and the protruding portion is a peripheral portion of the second supporting hole. By rotating the support shaft around the shaft so that the fitting protrusion is fitted in the fitting hole, the operation pedal is moved to the pedal. Configured to be supported by the bracket via the support shaft And it is characterized in that they are.

これによれば、嵌合突起部及び嵌合孔という簡単な構成で、回転規制手段を具現化することができる。   According to this, the rotation restricting means can be realized with a simple configuration of the fitting protrusion and the fitting hole.

また、突起部が第２支持孔の周縁部における通り抜け孔の形成部以外の部分に位置しかつ嵌合突起部が嵌合孔に嵌合されるように支軸をその軸周りに回転させることにより、操作ペダルがペダルブラケットに支軸を介して支持されるので、嵌合突起部を嵌合孔に嵌合させる作業を別に行う必要がなく、操作ペダルをペダルブラケットに支軸を介して支持させる作業をより一層簡単に行うことができる。   Further, the supporting shaft is rotated around the axis so that the protruding portion is located at a portion other than the through hole forming portion at the peripheral edge portion of the second support hole and the fitting protruding portion is fitted into the fitting hole. Since the operation pedal is supported by the pedal bracket via the support shaft, there is no need to separately perform the operation of fitting the fitting protrusion into the fitting hole, and the operation pedal is supported by the pedal bracket via the support shaft. It is possible to more easily perform the operation.

第４の発明は、上記第１〜３のいずれか１つの発明において、上記支軸の外周面には、上記操作ペダルが上記ペダルブラケットに上記支軸を介して支持された状態において上記通り抜け孔に対応する部分に、軸方向に延びる溝部が形成されていることを特徴とするものである。   According to a fourth aspect of the present invention, in any one of the first to third aspects, the through hole is formed on the outer peripheral surface of the support shaft in a state where the operation pedal is supported by the pedal bracket via the support shaft. A groove portion extending in the axial direction is formed in a portion corresponding to.

これによれば、支軸の外周面には、操作ペダルがペダルブラケットに支軸を介して支持された状態において通り抜け孔に対応する部分に、軸方向に延びる溝部を形成しているので、潤滑油を通り抜け孔及び溝部を介して固定部側の支軸と回転部側の操作ペダルとの間に供給することができ、通り抜け孔を利用して、その間の摩擦を抑制することができる。   According to this, a groove portion extending in the axial direction is formed on the outer peripheral surface of the support shaft in the portion corresponding to the through hole when the operation pedal is supported by the pedal bracket via the support shaft. Oil can be supplied between the support shaft on the fixed portion side and the operation pedal on the rotating portion side through the through hole and the groove portion, and friction between them can be suppressed by using the through hole.

本発明によれば、支軸をその軸方向他端部側からペダルブラケットの第１側板の第１支持孔及び操作ペダルに挿通させた後に、支軸をペダルブラケットの第２側板の第２支持孔に挿通させるとともに支軸の突起部を、第２側板の通り抜け孔を通り抜けさせ、突起部が第２支持孔の周縁部における通り抜け孔の形成部以外の部分に位置するように支軸をその軸周りに回転させることにより、操作ペダルがペダルブラケットに支軸を介して支持される。このように、突起部を第２支持孔の周縁部における通り抜け孔の形成部以外の部分に位置させることにより、操作ペダルがペダルブラケットに支軸を介して支持された状態において支軸をペダルブラケットや操作ペダルから抜け止めすることができ、操作ペダルをペダルブラケットに支軸を介して支持させるのに、支軸に、支軸をペダルブラケットや操作ペダルから抜け止めするための別部材を取り付ける必要がなく、その作業を簡単に行うことができる。   According to the present invention, the support shaft is inserted into the first support hole of the first side plate of the pedal bracket and the operation pedal from the other axial end side of the support shaft, and then the support shaft is second supported on the second side plate of the pedal bracket. The projecting portion of the support shaft is passed through the second side plate through-hole and the projecting portion of the support shaft is positioned at a portion other than the through-hole forming portion at the peripheral edge of the second support hole. By rotating around the shaft, the operation pedal is supported by the pedal bracket via the support shaft. In this way, by positioning the protruding portion at a portion other than the through-hole forming portion at the peripheral edge portion of the second support hole, the support shaft can be moved to the pedal bracket in a state where the operation pedal is supported by the pedal bracket via the support shaft. It is necessary to attach a separate member to the support shaft to prevent the support shaft from coming off from the pedal bracket or the operation pedal so that the operation pedal can be supported by the pedal bracket via the support shaft. The work can be done easily.

以下、本発明の実施形態を図面に基づいて詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１は、本発明の実施形態に係る操作ペダルの支持構造の斜視図であり、この操作ペダル１は、車体側に取り付けられるペダルブラケット２に車幅方向に延びる樹脂製の支軸３を介して車両前後方向に揺動自在に支持されるようになっている。操作ペダル１は、例えばクラッチペダルやブレーキペダル、アクセルペダルなどであり、本実施形態ではクラッチペダルである。操作ペダル１は、図１〜図３に示すように、半割形状の樹脂製の一対の半体を互いに突き合わせて筒形状に形成されていて、支軸３から下側に延びた後に車両後側斜め下側に延びている。操作ペダル１の上端部の車幅方向両端面における互いに対向する部分には、支軸３が挿通支持される円筒形状のボス部１０が車幅方向に延びるようにそれぞれ一体に形成されている。操作ペダル１の下端部には、その操作の際に運転者が踏み込む踏み込み部１１が設けられている。   FIG. 1 is a perspective view of a support structure for an operation pedal according to an embodiment of the present invention. The operation pedal 1 is connected to a pedal bracket 2 attached to the vehicle body via a resin support shaft 3 extending in the vehicle width direction. Thus, it is supported so as to be swingable in the longitudinal direction of the vehicle. The operation pedal 1 is, for example, a clutch pedal, a brake pedal, an accelerator pedal, or the like, and is a clutch pedal in this embodiment. As shown in FIGS. 1 to 3, the operation pedal 1 is formed in a cylindrical shape by abutting a pair of half-made resin halves together, and extends downward from the support shaft 3 before the rear of the vehicle. The side extends diagonally downward. Cylindrical boss portions 10 through which the support shaft 3 is inserted and supported are integrally formed at opposite ends of the upper end portion of the operation pedal 1 in the vehicle width direction so as to extend in the vehicle width direction. At the lower end of the operation pedal 1, a stepping portion 11 is provided for the driver to step on during the operation.

ペダルブラケット２は、図１〜図４に示すように、略コ字形状の金属製のものであって、互いに車幅方向（支軸３方向）に間隔を隔てて車両前後方向に延びる車両左側の第１側板２０及び車両右側の第２側板２１と、これらの両側板２０，２１の車両前側端縁部同士を互いに連結する連結板２２とを有している。第１側板２０の車両後側部分には、支軸３の軸方向一端部（図１では車両左側端部。以下、車両左側端部という）が挿通支持される円形状の第１支持孔２０ａが形成されている。第１側板２０の第１支持孔２０ａの上側部分及び下側部分には、後述する各嵌合突起部３１ａが嵌合可能な嵌合孔２０ｂが各嵌合突起部３１ａに対応するようにそれぞれ形成されている。   As shown in FIGS. 1 to 4, the pedal bracket 2 is made of a substantially U-shaped metal and extends in the vehicle front-rear direction with an interval in the vehicle width direction (support shaft 3 direction). The first side plate 20 and the second side plate 21 on the right side of the vehicle, and a connecting plate 22 for connecting the front end edges of the both side plates 20 and 21 to each other. In the vehicle rear side portion of the first side plate 20, a circular first support hole 20a into which an axial end portion of the support shaft 3 (vehicle left end portion in FIG. 1; hereinafter referred to as vehicle left end portion) is inserted and supported. Is formed. In the upper part and the lower part of the first support hole 20a of the first side plate 20, a fitting hole 20b into which each fitting projection 31a described later can be fitted corresponds to each fitting projection 31a. Is formed.

第２側板２１の車両後側部分における第１支持孔２０ａに対向する部分には、支軸３の軸方向他端部（図１では車両右側端部。以下、車両右側端部という）が挿通支持される円形状の第２支持孔２１ａが形成されている。第２支持孔２１ａの周縁部には、この第２支持孔２１ａに連続しかつ支軸３を第２支持孔２１ａに挿通させる際に後述する各突起部３４が通り抜け可能な４つの通り抜け孔２１ｂ，…が周方向に９０度間隔（等間隔）で各突起部３４に対応するように形成されている。これらの通り抜け孔２１ｂ，…は、第２支持孔２１ａから車両前側斜め上側、車両前側斜め下側、車両後側斜め上側、及び車両後側斜め下側にそれぞれ延びている。連結板２２は車幅方向に延びていて、エンジンルームと車室とを区画する車体側としてのダッシュパネル（図示せず）に取り付けられる。   The other end in the axial direction of the support shaft 3 (the vehicle right end in FIG. 1; hereinafter referred to as the vehicle right end) is inserted into the portion of the second side plate 21 facing the first support hole 20a in the rear portion. A circular second support hole 21a to be supported is formed. At the periphery of the second support hole 21a, there are four through holes 21b that are continuous with the second support hole 21a and through which each projection 34 described later can pass when the support shaft 3 is inserted into the second support hole 21a. Are formed so as to correspond to the protrusions 34 at intervals of 90 degrees (equal intervals) in the circumferential direction. These through holes 21b,... Extend from the second support hole 21a to the vehicle front side oblique upper side, the vehicle front side oblique lower side, the vehicle rear side oblique upper side, and the vehicle rear side oblique lower side, respectively. The connecting plate 22 extends in the vehicle width direction, and is attached to a dash panel (not shown) as a vehicle body that partitions the engine room and the vehicle compartment.

支軸３は、図１〜図５に示すように、円筒形状のピンであり、その中空部の車両左側端部は六角形状をなしている。支軸３の車両左側端部における第１支持孔２０ａに支持される部分の車両左側（軸方向外側）部分には、第１支持孔２０ａを通り抜け不能な略楕円形状の頭部３０が一体に形成されている。このように、頭部３０を、第１支持孔２０ａを通り抜け不能にすることにより、頭部３０は、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３をペダルブラケット２や操作ペダル１から抜け止めするようになっている。頭部３０における互いに支軸３径方向に対向する部分には、支軸３径方向外側（図１では上側及び下側）に突出する腕部３１がそれぞれ一体に形成されている。このように、腕部３１，３１は頭部３０の一部を構成している。各腕部３１の先端部の車両右側面（軸方向内側面）には、車両右側（軸方向内側）に突起する嵌合突起部３１ａが一体に形成されている。これらの嵌合突起部３１ａ，３１ａは、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において、嵌合孔２０ｂ，２０ｂにそれぞれ嵌合している。そして、嵌合突起部３１ａ及び嵌合孔２０ｂが、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３がその軸周りに回転するのを規制する回転規制手段を構成している。   As shown in FIGS. 1 to 5, the support shaft 3 is a cylindrical pin, and the vehicle left end portion of the hollow portion has a hexagonal shape. A substantially elliptical head 30 that cannot pass through the first support hole 20a is integrally formed on the left side (axially outer side) of the portion of the support shaft 3 that is supported by the first support hole 20a at the left end of the vehicle. Is formed. Thus, by making the head 30 impossible to pass through the first support hole 20a, the head 30 can support the support shaft 3 in a state where the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3. The pedal bracket 2 and the operation pedal 1 are prevented from coming off. Arms 31 projecting outward in the radial direction of the support shaft 3 (upper side and lower side in FIG. 1) are integrally formed at portions of the head 30 that are opposed to each other in the radial direction of the support shaft 3. Thus, the arm portions 31 and 31 constitute a part of the head 30. A fitting protrusion 31a that protrudes toward the vehicle right side (axially inner side) is integrally formed on the vehicle right side surface (axially inner surface) at the tip of each arm portion 31. These fitting protrusions 31a and 31a are fitted in fitting holes 20b and 20b, respectively, in a state where the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3. Then, the rotation restricting means that restricts the rotation of the support shaft 3 about the shaft in a state where the operation protrusion 1 is supported by the pedal bracket 2 via the support shaft 3. Is configured.

支軸３の車両右側端部には外径が縮径した縮径部３２が形成されており、この縮径部３２が第２支持孔２１に挿通支持される。縮径部３２と該縮径部３２の車両左側部分との間には円環形状の段差部３３が形成されている。縮径部３２における第２支持孔２１ａに支持される部分の車両右側部分（軸方向外側部分）の外周面には、径方向外側に突起する４つの突起部３４，…が周方向に９０度間隔（等間隔）で一体に形成されている。これらの突起部３４，…のうち互いに支軸３径方向に対向配置された２つの突起部３４，３４は、腕部３１，３１とそれぞれ車幅方向に対向配置されている。各突起部３４は、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において、第２支持孔２１ａの周縁部における通り抜け孔２１ｂ，…の形成部以外の部分、具体的には、第２支持孔２１ａの周縁部における互いに隣り合う２つの通り抜け孔２１ｂ，２１ｂの間の中間部に位置している。このように、各突起部３４を第２支持孔２１ａの周縁部における通り抜け孔２１ｂ，…の形成部以外の部分に位置させることにより、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３をペダルブラケット２や操作ペダル１から抜け止めするようになっている。各突起部３４と段差部３３との間には、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において、第２支持孔２１ａの周縁部が介在している。支軸３の車両右側端部は、全体として、支軸３を第１支持孔２０ａに挿通させる際に第１支持孔２０ａを通り抜け可能になっている。   A diameter-reduced portion 32 having a reduced outer diameter is formed at the vehicle right end portion of the support shaft 3, and this reduced-diameter portion 32 is inserted into and supported by the second support hole 21. An annular step portion 33 is formed between the reduced diameter portion 32 and the left side portion of the reduced diameter portion 32 in the vehicle. On the outer peripheral surface of the vehicle right side portion (axially outer portion) of the portion supported by the second support hole 21a in the reduced diameter portion 32, four projecting portions 34,... Projecting radially outward are 90 degrees in the circumferential direction. They are integrally formed at intervals (equal intervals). Of these projections 34,..., Two projections 34, 34 that are arranged to face each other in the radial direction of the support shaft 3 are arranged to face the arm portions 31, 31 respectively in the vehicle width direction. Each protrusion 34 is a portion other than the formation portion of the through holes 21b,. Is located in an intermediate portion between two adjacent through-holes 21b, 21b at the peripheral edge of the second support hole 21a. In this way, the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3 by positioning each projection 34 at a portion other than the formation portion of the through hole 21b,... At the peripheral edge of the second support hole 21a. In this state, the support shaft 3 is prevented from being detached from the pedal bracket 2 or the operation pedal 1. Between the protrusions 34 and the stepped portions 33, the peripheral portion of the second support hole 21 a is interposed in a state where the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3. The vehicle right end portion of the support shaft 3 can pass through the first support hole 20a as a whole when the support shaft 3 is inserted into the first support hole 20a.

支軸３の外周面には、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において各通り抜け孔２１ｂに対応する部分に、車幅方向に延びる溝部３５が形成されている。本実施形態では、溝部３５は、車幅方向から見て、各突起部３４の支軸３周方向両外側近傍部分にそれぞれ形成されている。そして、グリースなどの潤滑油を各通り抜け孔２１ｂ及び各溝部３５を介して固定部側の支軸３の外周面と回転部側の操作ペダル１のボス部１０，１０の内周面との間に供給して、その間の摩擦を抑制するようになっている。これから分かるように、各通り抜け孔２１ｂは、各突起部３４の通り抜け用と潤滑油の摩擦面への供給用とに兼用している。   A groove 35 extending in the vehicle width direction is formed on the outer peripheral surface of the support shaft 3 in a portion corresponding to each through hole 21b in a state where the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3. . In the present embodiment, the groove 35 is formed in the vicinity of both outer sides in the circumferential direction of the support shaft 3 of each projection 34 when viewed from the vehicle width direction. Then, lubricating oil such as grease is passed through the through holes 21b and the groove portions 35 between the outer peripheral surface of the support shaft 3 on the fixed portion side and the inner peripheral surfaces of the boss portions 10 and 10 of the operation pedal 1 on the rotating portion side. To suppress friction between them. As can be seen, each through hole 21b is used both for passing through each projection 34 and for supplying the lubricating oil to the friction surface.

−操作ペダルのペダルブラケットへの支持方法−
以下、操作ペダル１をペダルブラケット２に支持する方法について説明する。 -How to support the operation pedal to the pedal bracket-
Hereinafter, a method of supporting the operation pedal 1 on the pedal bracket 2 will be described.

まず、操作ペダル１をペダルブラケット２の第１及び第２側板２０，２１の間に配置して、操作ペダル１のボス部１０，１０の中空部を、車幅方向（支軸３方向）から見て、第１及び第２側板２０，２１の第１及び第２支持孔２０ａ，２１ａに重ならせる。その次に、支軸３をその車両右側端部側から、第１側板２０の車両左側面側より該第１側板２０の第１支持孔２０ａ及びボス部１０，１０の中空部にこの順に挿通させた後に、支軸３を第２側板２１の第２支持孔２１ａに挿通させるとともに支軸３の各突起部３４を、第２側板２１の各通り抜け孔２１ｂを通り抜けさせる。このとき、支軸３の頭部３０は第１支持孔２０ａを通り抜けない。また、支軸３を第２支持孔２１ａに挿通させるとともに各突起部３４を、各通り抜け孔２１ｂを通り抜けさせると、支軸３の各腕部３１の嵌合突起部３１ａが第１側板２０の車両左側面に当接するため、各腕部３１が撓んだ状態になる。尚、上述の如く、突起部３４，…及び通り抜け孔２１ｂ，…が、それぞれ、互いに対称性をもって配置されているため、各突起部３４をどの通り抜け孔２１ｂを通り抜けさせても、すべての突起部３４，…が通り抜け孔２１ｂ，…を通り抜ける。   First, the operation pedal 1 is disposed between the first and second side plates 20 and 21 of the pedal bracket 2, and the hollow portions of the boss portions 10 and 10 of the operation pedal 1 are arranged from the vehicle width direction (support shaft 3 direction). As seen, the first and second side plates 20 and 21 are overlapped with the first and second support holes 20a and 21a. Next, the support shaft 3 is inserted from the vehicle right end side into the first support hole 20a of the first side plate 20 and the hollow portions of the boss portions 10 and 10 in this order from the vehicle left side of the first side plate 20. Then, the support shaft 3 is inserted into the second support hole 21a of the second side plate 21 and the projections 34 of the support shaft 3 are passed through the through holes 21b of the second side plate 21. At this time, the head 30 of the support shaft 3 does not pass through the first support hole 20a. Further, when the support shaft 3 is inserted into the second support hole 21 a and the protrusions 34 are passed through the through holes 21 b, the fitting protrusions 31 a of the arm portions 31 of the support shaft 3 are formed on the first side plate 20. Since it contacts the left side of the vehicle, each arm 31 is bent. As described above, the protrusions 34,... And the through holes 21b,... Are arranged symmetrically with each other, so that all the protrusions can be passed through any of the protrusions 34 through any of the through holes 21b. 34,... Pass through the through holes 21b,.

その後に、各突起部３４が第２支持孔２１ａの周縁部における互いに隣り合う２つの通り抜け孔２１ｂ，２１ｂの間の中間部に位置しかつ各嵌合突起部３１ａが各嵌合孔２０ｂに嵌合されるように支軸３をその軸周りに回転させる。この回転の間、各嵌合突起部３１ａが第１側板２０に接触し続けるため、各腕部３１が継続して撓み状態となる。この撓み状態は、各嵌合突起部３１ａが各嵌合孔２０ｂに嵌合されるまで続き、各嵌合突起部３１ａが各嵌合孔２０ｂに嵌合されると、各腕部３１は元の状態に戻る。尚、上述の如く、突起部３４，３４が腕部３１，３１とそれぞれ車幅方向に対向配置されているため、各嵌合突起部３１ａが各嵌合孔２０ｂに嵌合されるように支軸３をその軸周りに回転させれば、各突起部３４は第２支持孔２１ａの周縁部における互いに隣り合う２つの通り抜け孔２１ｂ，２１ｂの間の中間部に移動する。このように、各突起部３４が第２支持孔２１ａの周縁部における互いに隣り合う２つの通り抜け孔２１ｂ，２１ｂの間の中間部に位置すると、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３がペダルブラケット２や操作ペダル１から抜け止めされる。また、各嵌合突起部３１ａが各嵌合孔２０ｂに嵌合されると、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３がその軸周りに回転して各突起部３４が各通り抜け孔２１ｂを通り抜けるのが規制され、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態が維持される。尚、上述の如く、嵌合突起部３１ａ，３１ａ及び嵌合孔２０ｂ，２０ｂが、それぞれ、互いに対称性をもって配置されているため、各嵌合突起部３１ａをどの嵌合孔２０ｂに嵌合しても、すべての嵌合突起部３１ａ，３１ａが嵌合孔２０ｂ，２０ｂに嵌合される。   Thereafter, each projection 34 is positioned at an intermediate portion between two adjacent through holes 21b and 21b at the peripheral edge of the second support hole 21a, and each fitting projection 31a is fitted into each fitting hole 20b. The support shaft 3 is rotated around the axis so as to be aligned. Since each fitting protrusion 31a keeps contacting the 1st side plate 20 during this rotation, each arm part 31 will be in a bending state continuously. This bending state continues until each fitting projection 31a is fitted into each fitting hole 20b, and when each fitting projection 31a is fitted into each fitting hole 20b, each arm 31 is the original. Return to the state. As described above, since the projections 34 and 34 are arranged to face the arm portions 31 and 31 in the vehicle width direction, the support projections 31a are fitted in the fitting holes 20b. When the shaft 3 is rotated around the axis, each projection 34 moves to an intermediate portion between the two through holes 21b and 21b adjacent to each other at the peripheral edge of the second support hole 21a. As described above, when each protrusion 34 is located at the intermediate portion between the two through holes 21b and 21b adjacent to each other at the peripheral edge of the second support hole 21a, the operation pedal 1 is interposed between the pedal bracket 2 and the support shaft 3. In this state, the support shaft 3 is prevented from coming off from the pedal bracket 2 and the operation pedal 1. Further, when each fitting protrusion 31a is fitted into each fitting hole 20b, the support shaft 3 rotates around its axis in a state where the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3. Thus, the projections 34 are restricted from passing through the respective through holes 21b, and the state where the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3 is maintained. As described above, since the fitting protrusions 31a and 31a and the fitting holes 20b and 20b are arranged symmetrically with each other, each fitting protrusion 31a is fitted in which fitting hole 20b. Even so, all the fitting protrusions 31a and 31a are fitted into the fitting holes 20b and 20b.

それから、ペダルブラケット２をダッシュパネルに取り付ける。以上のようにして、操作ペダル１がペダルブラケット２に支軸３を介して支持されかつペダルブラケット２が車体側に取り付けられた状態にする。そして、操作ペダル１は、運転者が踏み込み部１１を踏み込むと、支軸３を中心として車両前後方向に回動するようになっている。   Then, the pedal bracket 2 is attached to the dash panel. As described above, the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3 and the pedal bracket 2 is attached to the vehicle body side. When the driver depresses the stepping portion 11, the operation pedal 1 rotates about the support shaft 3 in the vehicle front-rear direction.

−効果−
以上により、本実施形態によれば、支軸３をその車両右側端部側から、ペダルブラケット２の第１側板２０の車両左側面側より該第１側板２０の第１支持孔２０ａ及び操作ペダル１に挿通させた後に、支軸３をペダルブラケット２の第２側板２１の第２支持孔２１ａに挿通させるとともに支軸３の突起部３４を、第２側板２１の通り抜け孔２１ｂを通り抜けさせ、突起部３４が第２支持孔２１ａの周縁部における通り抜け孔２１ｂの形成部以外の部分に位置するように支軸３をその軸周りに回転させることにより、操作ペダル１がペダルブラケット２に支軸３を介して支持される。このように、突起部３４を第２支持孔２１ａの周縁部における通り抜け孔２１ｂの形成部以外の部分に位置させることにより、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３をペダルブラケット２や操作ペダル１から抜け止めすることができる。したがって、操作ペダル１をペダルブラケット２に支軸３を介して支持させるのに、支軸３に、支軸３をペダルブラケット２や操作ペダル１から抜け止めするための別部材を取り付ける必要がなく、その作業を簡単に行うことができる。 -Effect-
As described above, according to the present embodiment, the support shaft 3 is moved from the vehicle right end side to the first support hole 20a of the first side plate 20 and the operation pedal from the vehicle left side of the first side plate 20 of the pedal bracket 2. 1, the support shaft 3 is inserted into the second support hole 21 a of the second side plate 21 of the pedal bracket 2 and the protrusion 34 of the support shaft 3 is passed through the through hole 21 b of the second side plate 21. By rotating the support shaft 3 around its axis so that the projection 34 is positioned at a portion other than the portion where the through hole 21b is formed at the peripheral edge of the second support hole 21a, the operation pedal 1 supports the pedal bracket 2 on the support shaft 21. 3 is supported. Thus, the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3 by positioning the protrusion 34 at a portion other than the portion where the through hole 21b is formed at the peripheral edge of the second support hole 21a. The supporting shaft 3 can be prevented from being detached from the pedal bracket 2 or the operation pedal 1. Therefore, in order to support the operation pedal 1 on the pedal bracket 2 via the support shaft 3, it is not necessary to attach a separate member to the support shaft 3 to prevent the support shaft 3 from coming off from the pedal bracket 2 or the operation pedal 1. That work can be done easily.

また、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３がその軸周りに回転するのを規制する回転規制手段を設けているので、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において支軸３がその軸周りに回転して突起部３４が通り抜け孔２１ｂを通り抜けるのを規制することでき、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態を維持することができる。   Further, since the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3, there is provided a rotation restricting means for restricting the rotation of the support shaft 3 around the support shaft 3. 2, while the support shaft 3 is supported via the support shaft 3, the support shaft 3 can be prevented from rotating around the shaft and the projecting portion 34 from passing through the through hole 21 b. It is possible to maintain the state supported via 3.

また、嵌合突起部３１ａ及び嵌合孔２０ｂという簡単な構成で、回転規制手段を具現化することができる。   Further, the rotation restricting means can be realized with a simple configuration of the fitting protrusion 31a and the fitting hole 20b.

また、突起部３４が第２支持孔２１ａの周縁部における通り抜け孔２１ｂの形成部以外の部分に位置しかつ嵌合突起部３１ａが嵌合孔２０ｂに嵌合されるように支軸３をその軸周りに回転させることにより、操作ペダル１がペダルブラケット２に支軸３を介して支持されるので、嵌合突起部３１ａを嵌合孔２０ｂに嵌合させる作業を別に行う必要がなく、操作ペダル１をペダルブラケット２に支軸３を介して支持させる作業をより一層簡単に行うことができる。   Further, the support shaft 3 is arranged so that the projection 34 is located at a portion other than the formation portion of the through hole 21b at the peripheral edge of the second support hole 21a and the fitting projection 31a is fitted into the fitting hole 20b. By rotating around the shaft, the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3, so that it is not necessary to separately perform the work of fitting the fitting protrusion 31a into the fitting hole 20b. The operation of supporting the pedal 1 on the pedal bracket 2 via the support shaft 3 can be performed more easily.

また、支軸３の外周面には、操作ペダル１がペダルブラケット２に支軸３を介して支持された状態において通り抜け孔２１ｂに対応する部分に、軸方向に延びる溝部３５を形成しているので、潤滑油を通り抜け孔２１ｂ及び溝部３５を介して固定部側の支軸３と回転部側の操作ペダル１との間に供給することができ、通り抜け孔２１ｂを利用して、その間の摩擦を抑制することができる。   Further, on the outer peripheral surface of the support shaft 3, a groove portion 35 extending in the axial direction is formed in a portion corresponding to the through hole 21b when the operation pedal 1 is supported by the pedal bracket 2 via the support shaft 3. Therefore, the lubricating oil can be supplied between the support shaft 3 on the fixed portion side and the operation pedal 1 on the rotating portion side through the through hole 21b and the groove portion 35, and the friction between them is made using the through hole 21b. Can be suppressed.
