　図８は図７のプルロッド部材１３０と操作レバー１２０とを連結する連結部１４０をＶＩＩＩ－ＶＩＩＩ線で切った断面を示す。図８に示すように、連結部１４０の構成は、ベース部材１１４の平板状部位１１６を挟む操作レバー１２０の両側の壁部１２０Ｒ、１２０Ｌの間にプルロッド部材１３０の結合部位１３２が配設され、ベース部材１１４とプルロッド部材１３０に連結ピン１４２を挿通させて、連結ピン１４２の他端をカシメて結合する構成である。 FIG. 8 is a cross-sectional view taken along the line VIII-VIII of the connecting portion 140 connecting the pull rod member 130 and the operation lever 120 of FIG. As shown in FIG. 8, the connecting portion 140 is configured such that the connecting portion 132 of the pull rod member 130 is disposed between the wall portions 120R and 120L on both sides of the operation lever 120 sandwiching the flat portion 116 of the base member 114, The connection pin 142 is inserted through the base member 114 and the pull rod member 130, and the other end of the connection pin 142 is connected by caulking.
　上記構成におけるプルロッド部材１３０は操作レバー１２０の両側に配設される壁部１２０Ｒ、１２０Ｌの間にあり、ベース部材１１４の平板状部位１１６の配設位置と車幅方向で同じ位置関係にある。すなわち、プルロッド部材１３０と平板状部位１１６は、上方から見た場合、同じライン上にあり、且つ、連結部１４０の位置は重複した位置関係にある。したがって、後方の取付フランジ部位１１８Ｒは、プルロッド部材１３０を避けて形成される。このため、後方の取付フランジ部位１１８Ｒは、平板状部位１１６の後部を側方（図７で見て手前側）に屈曲させ、更に、その下部を前方側（ＦＲ方向）に屈曲させて形成させている。すなわち、二度屈曲形成させて形成している。 に お け る The pull rod member 130 in the above configuration is located between the wall portions 120R and 120L disposed on both sides of the operation lever 120, and has the same positional relationship in the vehicle width direction as the disposed position of the flat plate portion 116 of the base member 114. That is, when viewed from above, the pull rod member 130 and the flat part 116 are on the same line, and the position of the connecting part 140 is in an overlapping positional relationship. Therefore, the rear mounting flange portion 118R is formed avoiding the pull rod member 130. For this reason, the rear mounting flange portion 118R is formed by bending the rear portion of the flat plate portion 116 to the side (front side in FIG. 7) and further bending the lower portion to the front side (FR direction). ing. That is, it is formed by bending twice.
　操作装置１１０におけるプルロッド部材１３０と操作レバー１２０とを連結する連結部１４０が図８に示すように構成されている場合、連結部１４０の組付けは、操作レバー１２０の両側の壁部１２０Ｒ、１２０Ｌの間にプルロッド部材１３０の結合部位１３２を挿し込んで、壁部１２０Ｒ、１２０Ｌの挿通孔１４６、１４８とプルロッド部材１３０の挿通孔１３３に連結ピン１４２を挿通させて、連結ピン１４２の端部をカシメる方法をとる。この場合、連結ピン１４２の差し込みに際して、壁部１２０Ｒ、１２０Ｌの挿通孔１４６、１４８とプルロッド部材１３０の挿通孔１３３とを位置合わせする必要がある。しかしながら、プルロッド部材１３０の結合部位１３２が挿し込まれる両側の壁部１２０Ｒ、１２０Ｌの間は、視認困難である。このため、挿通孔の位置合わせが困難であり、組付け作業性が悪いという不都合があった。 When the connecting portion 140 for connecting the pull rod member 130 and the operating lever 120 in the operating device 110 is configured as shown in FIG. 8, the connecting portion 140 is assembled with the wall portions 120R and 120L on both sides of the operating lever 120. The connecting portion 132 of the pull rod member 130 is inserted between them, and the connecting pin 142 is inserted into the through holes 146 and 148 of the walls 120R and 120L and the through hole 133 of the pull rod member 130, and the end of the connecting pin 142 is Take the method of caulking. In this case, it is necessary to align the insertion holes 146 and 148 of the walls 120R and 120L with the insertion hole 133 of the pull rod member 130 when inserting the connection pin 142. However, it is difficult to visually recognize between the wall portions 120R and 120L on both sides of the pull rod member 130 where the coupling portion 132 is inserted. For this reason, it is difficult to position the insertion hole, and there is a disadvantage that the assembling workability is poor.
　また、連結部１４０が上述のように構成されている場合、操作装置１１０におけるベース部材１１４の後方の取付フランジ部位１１８Ｒは、異なる方向への２回の曲げ加工により形成により行われる。このため、ベース部材１１４の成形前の展開形状が複雑な形状となり、ベース部材１１４を板材から切り出す際の歩留まりが悪くなるという不都合もある。 When the connecting portion 140 is configured as described above, the mounting flange portion 118R behind the base member 114 in the operating device 110 is formed by bending twice in different directions. For this reason, the unfolded shape of the base member 114 before forming becomes a complicated shape, and there is also an inconvenience that the yield when cutting the base member 114 from the plate material is deteriorated.
　このため、プルロッド部材を操作レバーに連結する連結部を視認可能な位置に配設することにより、組付け作業性の向上を図ることが望まれる。 Therefore, it is desired to improve the assembling workability by arranging a connecting portion for connecting the pull rod member to the operation lever at a visible position.

　以下、本発明の各種実施形態について図面を参照しながら説明する。図１に示した一つの実施形態としての車両用パーキングブレーキの操作装置は、手動でレバーを回動させるタイプのものであり、運転者がレバーを引っ張ることによりパーキングブレーキを働かせ、戻すことによりパーキングブレーキを解除する。操作装置は自動車等の車両における運転席と助手席との間に配置される。通常、同位置に配置されるセンターコンソールボックスに組込まれて配置される。なお、各図に適宜示す方向表示は、車両の通常の進行状態における姿勢の方向を示し、矢印ＦＲは車両前方方向、矢印ＵＰは車両上方向、矢印ＷＲは車幅方向の右側方向を示す。以下の説明において、方向に関する記述は、この方向を基準として示す。 Hereinafter, various embodiments of the present invention will be described with reference to the drawings. The operating device for a vehicle parking brake as one embodiment shown in FIG. 1 is of a type in which a lever is manually rotated, and the driver operates the parking brake by pulling the lever, and returns the parking brake by returning the lever. Release the brake. The operating device is arranged between a driver's seat and a passenger seat in a vehicle such as an automobile. Usually, it is installed in a center console box arranged at the same position. The direction display appropriately shown in each figure indicates the direction of the posture of the vehicle in the normal traveling state, where the arrow FR indicates the vehicle front direction, the arrow UP indicates the vehicle upward direction, and the arrow WR indicates the right direction in the vehicle width direction. In the following description, the description relating to the direction is based on this direction.
　先ず、図１及び図２を参照しながら、操作装置１０の全体構成を説明する。図１は操作装置１０を前方の右側上方から見た斜視図であり、図２は操作装置１０を前方の左側上方から見た斜視図である。操作装置１０は、車両への取付面である床面１２に対して立設状態で配設される。そして、操作装置１０は、ベース部材１４と、操作レバー２０と、プルロッド部材３０とを備える。なお、ベース部材１４は通称セクタとも称される部材である。 First, the overall configuration of the operating device 10 will be described with reference to FIGS. FIG. 1 is a perspective view of the operating device 10 as viewed from the upper right front, and FIG. 2 is a perspective view of the operating device 10 as viewed from upper left front. The operating device 10 is provided in an upright state with respect to a floor surface 12 which is a mounting surface to a vehicle. The operating device 10 includes a base member 14, an operating lever 20, and a pull rod member 30. The base member 14 is a member commonly called a sector.
　ベース部材１４は厚みのある高剛性の板材で形成されており、平板状部位１６と、この平板状部位１６の下縁から略直角に屈曲して形成されている取付フランジ部位１８Ｆ、１８Ｒとから成っている。平板状部位１６は車両の床面１２に対しパーキングブレーキの操作方向（車両の前後方向）に立設した状態で配設される。平板状部位１６の外形形状は、図３の側面図に良く示されるように、上方が尖った概略３角形状の山形状に形成されている。山形状の上部の先端は後方寄りの位置とされている。これは後述する操作レバー２０との配設関係からの要請である。 The base member 14 is formed of a thick and high-rigidity plate material, and includes a flat portion 16 and mounting flange portions 18F and 18R which are formed by bending the lower edge of the flat portion 16 at substantially right angles. Made up of The plate-like portion 16 is provided so as to stand upright on the floor surface 12 of the vehicle in the parking brake operation direction (the front-rear direction of the vehicle). As shown in the side view of FIG. 3, the external shape of the flat plate portion 16 is formed in a substantially triangular mountain shape with a sharp upper part. The tip of the upper part of the mountain shape is located closer to the rear. This is a request from the arrangement relationship with the operation lever 20 described later.
　前側取付フランジ部位１８Ｆと後側取付フランジ部位１８Ｒとは平板状部位１６を挟んで反対方向に屈曲している。前側取付フランジ部位１８Ｆは左側方向に屈曲し、後側取付フランジ部位１８Ｒは右側方向に屈曲している。それぞれの取付フランジ部位１８Ｆ、１８Ｒの形状は、図４の上面図で見ると良く分かるように、前側取付フランジ部位１８Ｆは三角形状に形成されており、後側取付フランジ部位１８Ｒは半楕円形状として形成されている。 The front mounting flange portion 18F and the rear mounting flange portion 18R are bent in opposite directions with the flat portion 16 interposed therebetween. The front mounting flange portion 18F is bent leftward, and the rear mounting flange portion 18R is bent rightward. As can be clearly seen from the top view of FIG. 4, the shape of each of the mounting flange portions 18F and 18R is such that the front mounting flange portion 18F is formed in a triangular shape, and the rear mounting flange portion 18R is formed as a semi-elliptical shape. Is formed.
　前側取付フランジ部位１８Ｆと後側取付フランジ部位１８Ｒのそれぞれには取付孔２６Ｆ、２６Ｒが形成されている。取付フランジ部位１８Ｆ、１８Ｒは床面１２に面しており、取付孔２６Ｆ、２６Ｒにボルト等の締着手段を通して床面１２にねじ込むことにより取付フランジ部位１８Ｆ、１８Ｒを床面に固定する。その結果、ベース部材１４の平板状部位１６は床面に対して立設される。なお、ベース部材１４は、板材を所定形状にブランキングして、プレス成形により取付フランジ部位１８Ｆ、１８Ｒを屈曲させることにより形成される。 取 付 Mounting holes 26F and 26R are formed in the front mounting flange portion 18F and the rear mounting flange portion 18R, respectively. The mounting flange portions 18F and 18R face the floor surface 12. The mounting flange portions 18F and 18R are fixed to the floor surface by screwing the mounting holes 26F and 26R into the floor surface 12 through fastening means such as bolts. As a result, the flat portion 16 of the base member 14 stands on the floor. The base member 14 is formed by blanking a plate material into a predetermined shape and bending the mounting flange portions 18F and 18R by press molding.
　操作レバー２０はベース部材１４の平板状部位１６を挟む二つの壁部２０Ｌ、２０Ｒを有する。そして、操作レバー２０は回動ピン２８により平板状部位１６に回動可能に軸支されている。回動ピン２８は両側の壁部２０Ｌ、２０Ｒに跨がって配設されており、カシメ等により操作レバー２０に固定されている。なお、回動ピン２８は平板状部位１６に穿設された挿通孔を貫通して配設されている。 The operation lever 20 has two walls 20L and 20R sandwiching the flat portion 16 of the base member 14. The operation lever 20 is rotatably supported on the flat portion 16 by a rotation pin 28. The rotation pin 28 is disposed so as to straddle both side walls 20L and 20R, and is fixed to the operation lever 20 by caulking or the like. In addition, the rotation pin 28 is disposed so as to pass through an insertion hole formed in the flat plate-shaped portion 16.
　操作レバー２０の上部には操作アーム部２２が配設されており、操作アーム部２２の前方部位は運転者が操作時に把持するグリップ２３となっている。運転者がこのグリップ２３を手で把持して図１及び図２に示す矢印Ｘ、Ｙ方向に動かすことにより、操作レバー２０は回動ピン２８の周りに回動する。通常は、Ｘ方向の引き上げによりパーキングブレーキを効かせ、Ｙ方向の戻しによりパーキングブレーキを解除する。 (4) An operation arm 22 is provided above the operation lever 20, and a front portion of the operation arm 22 is a grip 23 which is gripped by the driver during operation. When the driver grips the grip 23 by hand and moves the grip 23 in the directions of arrows X and Y shown in FIGS. 1 and 2, the operation lever 20 rotates around the rotation pin 28. Normally, the parking brake is activated by raising in the X direction, and released by returning in the Y direction.
　操作レバー２０には爪部材（図示しない）が回転可能に支持されている。操作レバー２０を引き上げると、ベース部材１４に設けられたラチェット（これも図示しない）にこの爪部材が噛み合って操作レバー２０が引き上げ位置に保持される。グリップ２３の前方先端部には、パーキングブレーキを解除する時の押しボタン２４が設けられている。操作レバー２０をさらに少し引き上げながらこの押しボタン２４を押し込むと、爪部材が回動してラチェットに対する噛み合いが外れ、操作アーム部２２のＹ方向の戻し操作が可能となる。 爪 A claw member (not shown) is rotatably supported by the operation lever 20. When the operation lever 20 is raised, the pawl member is engaged with a ratchet (also not shown) provided on the base member 14, and the operation lever 20 is held at the raised position. At the front end of the grip 23, a push button 24 for releasing the parking brake is provided. When the push button 24 is pushed in while the operation lever 20 is further pulled up slightly, the pawl member is rotated and disengaged from the ratchet, and the operation arm 22 can be returned in the Y direction.
　操作レバー２０の回動は、連結部４０を介してプルロッド部材３０に軸方向動作として伝達される。実施形態によっては、プルロッド部材３０の軸方向動作は張力を分配するためのイコライザ３４に伝達される。このため、プルロッド部材３０はイコライザロッドと称されることもある。この場合、プルロッド部材３０は操作レバー２０とイコライザ３４との間に配設される伝達部材である。プルロッド部材３０は、高剛性の棒形状部材とすることができる。 回 動 The rotation of the operation lever 20 is transmitted to the pull rod member 30 via the connecting portion 40 as an axial operation. In some embodiments, the axial movement of the pull rod member 30 is transmitted to an equalizer 34 for distributing tension. For this reason, the pull rod member 30 may be called an equalizer rod. In this case, the pull rod member 30 is a transmission member disposed between the operation lever 20 and the equalizer 34. The pull rod member 30 can be a highly rigid rod-shaped member.
　図１、図２のようにイコライザ３４に伝達されたプルロッド部材３０の軸方向動作は、線図で示すように、通常、車両の左右後輪に備えられるホイールブレーキ３６にケーブル３８等の伝達部材を介して伝達される。なお、ホイールブレーキ３６を効かせるときには操作アーム部２２の引き上げ力が伝えられる。しかし、ホイールブレーキ３６の解除は、通常、ホイールブレーキ３６自体に備えられているばねによりなされる。操作アーム部２２を下ろすことによりケーブル３８の張力が緩み、ホイールブレーキ３６のばねの付勢力によりホイールブレーキ３６の解除が行われる。 As shown in the diagrams, the axial movement of the pull rod member 30 transmitted to the equalizer 34 as shown in FIGS. 1 and 2 is generally performed by a transmission member such as a cable 38 to a wheel brake 36 provided on the left and right rear wheels of the vehicle. Is transmitted via When the wheel brake 36 is applied, the lifting force of the operation arm 22 is transmitted. However, the release of the wheel brake 36 is normally performed by a spring provided on the wheel brake 36 itself. By lowering the operation arm 22, the tension of the cable 38 is relaxed, and the wheel brake 36 is released by the urging force of the spring of the wheel brake 36.
　操作レバー２０とプルロッド部材３０とを連結する連結部４０は、左側の壁部２０Ｌの外面に設定されている。一つの実施形態としては、図２に良く示されるように、ベース部材１４における平板状部位１６の左側に配設される操作レバー２０の外面に配設されている。そして、この連結部４０におけるプルロッド部材３０は、ベース部材１４の平板状部位１６の平面から水平方向にオフセットした位置にある。このオフセット配置は、図４、図５、及び図６から理解することができる。図４、図５、及び図６に、平板状部位１６の平面を直線Ｌ１として示し、プルロッド部材３０の軸線を直線Ｌ２として示し、オフセット距離をＳとして示した。 連結 The connecting portion 40 connecting the operating lever 20 and the pull rod member 30 is set on the outer surface of the left wall portion 20L. In one embodiment, as shown in FIG. 2, it is disposed on an outer surface of an operation lever 20 disposed on the left side of the flat portion 16 of the base member 14. The pull rod member 30 in the connecting portion 40 is located at a position horizontally offset from the plane of the flat portion 16 of the base member 14. This offset arrangement can be understood from FIGS. 4, 5 and 6. 4, 5, and 6, the plane of the flat portion 16 is shown as a straight line L1, the axis of the pull rod member 30 is shown as a straight line L2, and the offset distance is shown as S.
　図６に示されるように、一つの実施形態として、連結部４０は、連結ピン４２を介してプルロッド部材３０を回動可能に支持する。連結ピン４２は、プルロッド部材３０の結合部位３２に形成された挿通孔３３、ベース部材１４の平板状部位１６に形成された回動規制孔４４、及び、操作レバー２０の両側の壁部２０Ｌ、２０Ｒに形成された挿通孔４６、４８を貫通して配設される。連結ピン４２の頭部４２Ｈ側にプルロッド部材３０の結合部位３２が配設され、連結ピン４２の反対側の先端がカシメられて固定される。なお、結合部位３２の挿通孔３３、操作レバー２０の両側の壁部２０Ｌ、２０Ｒの挿通孔４６、４８は、貫通される連結ピン４２の軸径に対応した丸孔に形成されている。 As shown in FIG. 6, as one embodiment, the connecting portion 40 rotatably supports the pull rod member 30 via the connecting pin 42. The connection pin 42 has an insertion hole 33 formed in the coupling portion 32 of the pull rod member 30, a rotation restricting hole 44 formed in the flat plate-shaped portion 16 of the base member 14, and walls 20 </ b> L on both sides of the operation lever 20. It is disposed so as to penetrate through the insertion holes 46 and 48 formed in the 20R. The connecting portion 32 of the pull rod member 30 is disposed on the head 42H side of the connecting pin 42, and the tip on the opposite side of the connecting pin 42 is caulked and fixed. In addition, the insertion hole 33 of the coupling portion 32 and the insertion holes 46 and 48 of the walls 20L and 20R on both sides of the operation lever 20 are formed as round holes corresponding to the shaft diameter of the connecting pin 42 penetrated.
　平板状部位１６に形成された回動規制孔４４は、回動ピン２８の軸を中心とした円弧形状の長孔に形成されている。図３に円弧形状の回動規制孔４４が破線で示されている。この円弧形状の回動規制孔４４の中を連結ピン４２が動くことにより操作レバー２０が回動する。そして、回動規制孔４４の円弧形状の両端部に連結ピン４２が当接することにより、操作レバー２０の回動が所定の範囲に規制される。このように、連結ピン４２は、プルロッド部材３０を操作レバー２０に連結する機能と、操作レバー２０の回動範囲を規制する機能を合わせて果たしている。これによりそれぞれの機能に対してそれぞれのピンを設ける場合に比べ１本ピンの本数を減少させることができる。 回 動 The rotation restricting hole 44 formed in the flat plate-shaped portion 16 is formed as an arc-shaped long hole around the axis of the rotation pin 28. In FIG. 3, the arc-shaped rotation restricting hole 44 is indicated by a broken line. When the connecting pin 42 moves in the arc-shaped rotation restricting hole 44, the operation lever 20 rotates. The rotation of the operation lever 20 is restricted to a predetermined range by the contact of the connecting pin 42 with the arc-shaped ends of the rotation restriction hole 44. As described above, the connection pin 42 has both a function of connecting the pull rod member 30 to the operation lever 20 and a function of restricting the rotation range of the operation lever 20. Thereby, the number of one pin can be reduced as compared with the case where each pin is provided for each function.
　また、図６に示すように、プルロッド部材３０とベース部材１４の平板状部位１６との間に介在する操作レバー２０の左側の壁部２０Ｌは、連結ピン４２の周りで平板状部位１６からプルロッド部材３０に向かって持ち上げられた座面を有する。これにより、プルロッド部材３０は座面に接しながら回動するため、プルロッド部材３０は座面の周囲の表面から浮いた位置に保持され、パーキングブレーキ操作時におけるプルロッド部材３０と操作レバー２０との擦れを防止することができる。特に、プルロッド部材３０の軸方向作動時における操作レバー２０の壁部２０Ｌの縁部との擦れを防止することができる。その結果、異音および摩耗の防止を図ることができる。 As shown in FIG. 6, the left wall 20L of the operation lever 20 interposed between the pull rod member 30 and the flat plate portion 16 of the base member 14 is pulled from the flat plate portion 16 around the connection pin 42 by the pull rod. It has a seat raised to the member 30. As a result, the pull rod member 30 rotates while being in contact with the seat surface, so that the pull rod member 30 is held at a position floating above the surface around the seat surface, and the pull rod member 30 and the operation lever 20 are rubbed during parking brake operation. Can be prevented. In particular, it is possible to prevent the operation lever 20 from rubbing against the edge of the wall 20L when the pull rod member 30 is operated in the axial direction. As a result, abnormal noise and wear can be prevented.
　なお、図１～図３において、操作レバー２０の壁部２０Ｌ、２０Ｒの外面に形成されているビード５０は、操作レバー２０の面強度を強化するためのものである。また、図２及び図３に示される操作レバー２０の下面と接触する状態で配設される検知手段５２は、パーキングブレーキの操作状態を電気的に検知するためのものである。 In FIGS. 1 to 3, the beads 50 formed on the outer surfaces of the walls 20L and 20R of the operation lever 20 are for enhancing the surface strength of the operation lever 20. The detection means 52 provided in contact with the lower surface of the operation lever 20 shown in FIGS. 2 and 3 is for electrically detecting the operation state of the parking brake.
　次に、以上に説明した実施形態の利点を挙げる。先ず、プルロッド部材３０を操作レバー２０に連結する連結部４０は、その組立作業者が視認することのできる操作レバー２０の左側の壁部２０Ｌの外面にあり、ベース部材１４の平板状部位１６から平面方向にオフセットした位置とされている。このため、連結ピン４２を挿通するためのプルロッド部材３０の結合部位３２に形成する挿通孔３３と、左側の壁部２０Ｌに形成する挿通孔４６との位置合わせを視認状態で容易且つ確実に行うことができる。その結果、位置合わせした挿通孔３３、４６、及び平板状部位１６に形成される回動規制孔４４、更に操作レバー２０の右側の壁部２０Ｒに形成される挿通孔４８に、連結ピン４２を容易且つ確実に挿入することができる。したがって、連結部の組付け作業を容易且つ確実に行うことができる。 Next, advantages of the above-described embodiment will be described. First, the connecting portion 40 for connecting the pull rod member 30 to the operation lever 20 is located on the outer surface of the left wall 20L of the operation lever 20 that can be visually recognized by the assembling operator. The position is offset in the plane direction. For this reason, the positioning between the insertion hole 33 formed in the coupling portion 32 of the pull rod member 30 for inserting the connecting pin 42 and the insertion hole 46 formed in the left wall 20L is performed easily and reliably in a visible state. be able to. As a result, the connecting pin 42 is inserted into the aligned insertion holes 33 and 46, the rotation restricting hole 44 formed in the plate-shaped portion 16, and the insertion hole 48 formed in the right wall 20 </ b> R of the operation lever 20. It can be inserted easily and reliably. Therefore, the assembling work of the connecting portion can be easily and reliably performed.
　なお、ベース部材１４の平板状部位１６に形成される回動規制孔４４は、視認が困難な位置にあるが、回動ピン２８によるベース部材１４と操作レバー２０との組立により自動的に位置合わせされる。したがって、積極的に位置合わせする必要がない。同様に、操作レバー２０の反対側（右側）の壁部２０Ｒに形成される挿通孔４８も予め左側の操作レバー２０に形成される挿通孔４６と位置合わせして形成されるので、位置合わせする必要がないものである。 The rotation restricting hole 44 formed in the flat plate-shaped portion 16 of the base member 14 is located at a position where it is difficult to visually recognize the position. Be matched. Therefore, there is no need to actively perform the alignment. Similarly, the insertion hole 48 formed in the wall portion 20R on the opposite side (right side) of the operation lever 20 is formed in advance by being aligned with the insertion hole 46 formed in the left operation lever 20. It is not necessary.
　次に、ベース部材１４における平板状部位１６から屈曲形成される前側取付フランジ部位１８Ｆ及び後側取付フランジ部位１８Ｒはいずれも、平板状部位１６から１回の曲げ加工により形成されている。この様に曲げ加工が１回のみであると、ベース部材１４の成形前の展開形状を単純な形状とすることができて、ベース部材１４を形成する板材（素材）の歩留まりの向上を図ることができる。 Next, the front mounting flange portion 18F and the rear mounting flange portion 18R formed by bending from the flat plate portion 16 of the base member 14 are both formed by a single bending process from the flat plate portion 16. If the bending process is performed only once, the unfolded shape of the base member 14 before forming can be made simple, and the yield of the plate material (material) forming the base member 14 can be improved. Can be.
　また、以上の実施形態では、前側取付フランジ部位１８Ｆと後側取付フランジ部位１８Ｒは反対方向に屈曲している。具体的には前側取付フランジ部位１８Ｆは車幅方向左方向に屈曲し、後側取付フランジ部位１８Ｒは車幅方向右方向に屈曲している。これにより、操作装置１０はバランスよく、安定した配置状態として床面１２に取り付けられる。 In the above embodiment, the front mounting flange portion 18F and the rear mounting flange portion 18R are bent in opposite directions. Specifically, the front mounting flange portion 18F is bent leftward in the vehicle width direction, and the rear mounting flange portion 18R is bent rightward in the vehicle width direction. Thereby, the operating device 10 is mounted on the floor 12 in a well-balanced and stable arrangement state.
　また、連結部４０におけるプルロッド部材３０と、連結部４０の近傍位置に配設される後側取付フランジ部位１８Ｒは、ベース部材１４の平板状部位１６を挟んで反対側にある（図４参照）。これにより、図５及び図６に示されように、プルロッド部材３０と後側取付フランジ部位１８Ｒとが干渉することがなく、後側取付フランジ部位１８Ｒがプルロッド部材３０の作動の障害となることがない。また、後側取付フランジ部位１８Ｒが干渉しない結果、その分だけプルロッド部材３０の位置を低く設定することも可能となる。 Further, the pull rod member 30 in the connecting portion 40 and the rear mounting flange portion 18R disposed near the connecting portion 40 are on opposite sides of the flat portion 16 of the base member 14 (see FIG. 4). . Thereby, as shown in FIGS. 5 and 6, the pull rod member 30 and the rear mounting flange portion 18R do not interfere with each other, and the rear mounting flange portion 18R may obstruct the operation of the pull rod member 30. Absent. Further, as a result of the rear mounting flange portion 18R not interfering, the position of the pull rod member 30 can be set lower by that amount.
　別の実施形態として、図７に示す形状のベース部材をそのまま用いることもできる。すなわち、後方の取付けフランジ部位を２回の曲げ加工で形成したものであっても良い。この場合、図７に示した操作装置との間でベース部材を共用できる。 と し て As another embodiment, a base member having the shape shown in FIG. 7 can be used as it is. That is, the rear mounting flange portion may be formed by bending twice. In this case, the base member can be shared with the operating device shown in FIG.
　また、プルロッド部材とプルロッド部材近傍に配設される取付けフランジ部位は、上述の実施形態ではベース部材を挟んで反対側にあったが、別の実施形態として、両者とも同じ側にあってもよい。 In addition, although the pull rod member and the mounting flange portion disposed near the pull rod member are on the opposite side across the base member in the above-described embodiment, both may be on the same side as another embodiment. .
　また、上記の実施形態では、ベース部材の平板状部位に穿設した回動規制孔に差し込むピンとしてプルロッド部材のための連結ピンを利用することにより、ピンの本数を１本減らした。しかし、別の実施形態として、専用のピンを使用してもよい。 In the above-described embodiment, the number of pins is reduced by one by using a connecting pin for the pull rod member as a pin to be inserted into the rotation restricting hole formed in the flat plate-shaped portion of the base member. However, in another embodiment, dedicated pins may be used.
　また、上記の実施形態では、連結部におけるプルロッド部材を、ベース部材の平板状部位から浮かせた。しかし、別の実施形態として、必ずしも浮かせる必要はない。 Further, in the above embodiment, the pull rod member in the connecting portion is floated from the flat portion of the base member. However, in another embodiment, it is not always necessary to float.
　以上で述べた実施形態では、プルロッド部材を操作レバーに連結する連結部は、ベース部材の平板状部位の平面からオフセットしており、操作レバーの壁部の外面に設定されている。壁部の外面は連結部の組付け作業をする際、視認することができるので、その組み付け作業を容易に且つ確実に行うことができる。 In the embodiment described above, the connecting portion connecting the pull rod member to the operation lever is offset from the plane of the flat portion of the base member, and is set on the outer surface of the wall of the operation lever. Since the outer surface of the wall portion can be visually recognized when assembling the connecting portion, the assembling operation can be performed easily and reliably.
　ベース部材における平板状部位から屈曲形成される取付フランジ部位は、平板状部位から１回の屈曲形成により形成される。この様に屈曲形成が１回のみであると、ベース部材の成形前の展開形状を単純な形状とすることができて、ベース部材を形成する板材（素材）の歩留まりの向上を図ることができる。 取 付 The mounting flange portion formed by bending the flat portion of the base member is formed by bending once from the flat portion. If the bending is performed only once in this manner, the unfolded shape of the base member before molding can be made simple, and the yield of the plate (material) forming the base member can be improved. .
　連結部におけるプルロッド部材と、連結部の近傍位置に配設されるベース部材の取付フランジ部位は、ベース部材の平板状部位を挟んで反対側とされている。これにより、プルロッド部材と取付フランジ部位とが干渉することがなく、取付フランジ部位がプルロッド部材の作動の障害となることがない。また、取付フランジ部位が干渉しない結果、その分だけプルロッドの位置を低く設定することも可能となる。 (4) The mounting flange portion of the pull rod member in the connection portion and the base member disposed near the connection portion is on the opposite side of the flat portion of the base member. Accordingly, the pull rod member does not interfere with the mounting flange portion, and the mounting flange portion does not hinder the operation of the pull rod member. In addition, as a result of the mounting flange not interfering, the position of the pull rod can be set lower by that amount.
　操作レバーとプルロッド部材とを連結する連結部は連結ピンを用いており、連結ピンはベース部材の平板状部位に穿設されるパーキングブレーキ操作の回動規制孔に挿通されている。これにより、連結ピンによりプルロッド部材の連結と、操作レバーのパーキングブレーキ操作を回動規制する２つの機能を果たしているので、ピンの設定を１本減少させることができる。 連結 A connecting portion for connecting the operating lever and the pull rod member uses a connecting pin, and the connecting pin is inserted into a rotation restricting hole for a parking brake operation formed in a flat portion of the base member. Thus, since the connecting pin has two functions of connecting the pull rod member and restricting rotation of the parking brake operation of the operation lever, the number of pins can be reduced by one.
　操作レバーが、連結ピンの周りでベース部材の平板状部位から浮いて離間している。これにより、プルロッド部材は操作レバーから浮いた状態となる。このため、パーキングブレーキ操作時におけるプルロッド部材と操作レバーとの擦れを防止することができる。特に、プルロッド部材の軸方向作動時における操作レバーの縁部との擦れを防止することができる。その結果、異音および摩耗の防止を図ることができる。 (4) The operation lever floats away from the flat portion of the base member around the connection pin. As a result, the pull rod member floats from the operation lever. Therefore, it is possible to prevent friction between the pull rod member and the operation lever when the parking brake is operated. In particular, it is possible to prevent the pull rod member from rubbing against the edge of the operation lever during the axial operation. As a result, abnormal noise and wear can be prevented.
　以上、本発明を具体的な実施形態で説明したが、本発明はこれらの実施形態に限定されるものではなく、当業者であれば本発明の目的を逸脱することなく様々な置換、改良、変更を施すことが可能である。 As described above, the present invention has been described with the specific embodiments. However, the present invention is not limited to these embodiments, and those skilled in the art can make various substitutions, improvements, and modifications without departing from the objects of the present invention. Changes can be made.
