Description
本発明は、例えばトラックの側方下部に設けられ、車外の物体を巻き込むことを抑制する、車両のバンパ構造と、当該構造に適用されるバンパずれ止め板に関するものである。 This invention relates to a vehicle bumper structure, for example, one provided on the lower side of a truck, which prevents objects from being caught inside the vehicle, and to a bumper anti-slip plate applied to this structure.
従来のバンパ構造の一例として、例えば特許文献１に記載のものがある。この従来のバンパ構造では、上下方向に延びるステーに対し、車両前後方向に延びる丸パイプを、ステーにボルト止めした押さえ金具で押さえつけて固定していた。 One example of a conventional bumper structure is described in Patent Document 1. In this conventional bumper structure, a round pipe extending in the vehicle's front-to-rear direction was secured to a vertically extending stay using a retaining bracket bolted to the stay.
しかし、このように押さえ金具で丸パイプを押さえつけるような固定では、車両走行の際の振動等により押さえ金具に緩みが生じた場合、丸パイプに、車両前後方向にずれたり、回転したりするような変位が生じることにより、丸パイプを複数用いてバンパ構造を構成していた場合、各丸パイプの端部の位置や角度（特に曲げ加工されていた場合）がばらばらになることで、バンパ構造の見た目が悪くなるという問題があった。 However, with this method of securing the round pipes using retaining clips, if the clips loosen due to vibrations during vehicle operation, the round pipes can shift or rotate in the vehicle's longitudinal direction. If multiple round pipes are used to construct the bumper structure, this can cause the positions and angles of the ends of each pipe (especially if they are bent) to become inconsistent, resulting in an unsightly appearance of the bumper structure.
そこで本発明は、ステーに対するパイプ材の変位を抑制した車両のバンパ構造と、バンパずれ止め板を提供することを課題とする。 Therefore, the object of this invention is to provide a vehicle bumper structure that suppresses the displacement of pipe material relative to the stay, and a bumper slip prevention plate.
本発明の構成の一つは、車両の周囲部分に設けられるバンパ構造であって、前記車両の本体に取り付けられるステーと、棒状体から構成され、前記ステーに交差して設けられたバンパ部と、前記ステーに対して前記バンパ部を前記交差した状態で保持する締結部材と、前記ステーに対する前記バンパ部のずれを抑制するバンパずれ止め板と、を備え、前記締結部材は、前記バンパ部の外方に位置して前記バンパ部を前記ステーに対して当接させる押さえ部と、前記押さえ部から突出し前記ステーを貫通して前記ステーに固定される貫通棒と、を備え、前記バンパずれ止め板は、前記バンパ部と前記押さえ部との間に介在し、前記バンパ部の外周面に沿う板状体であって、前記貫通棒が係合する係合部と、前記バンパ部を固定する固定部と、を備える車両のバンパ構造である。 One configuration of the present invention is a bumper structure provided on the periphery of a vehicle, comprising: a stay attached to the main body of the vehicle; a bumper portion composed of a rod-shaped body and provided intersecting the stay; a fastening member that holds the bumper portion in the intersecting position relative to the stay; and a bumper slip prevention plate that suppresses displacement of the bumper portion relative to the stay. The fastening member comprises a pressing portion located outside the bumper portion and causing the bumper portion to abut against the stay, and a through-rod protruding from the pressing portion and penetrating the stay, and fixed to the stay. The bumper slip prevention plate is interposed between the bumper portion and the pressing portion, is a plate-shaped body along the outer circumferential surface of the bumper portion, and comprises an engaging portion that engages with the through-rod and a fixing portion that fixes the bumper portion.
前記構成によれば、バンパずれ止め板をバンパ部と押さえ部との間に介在させることで、締結部材と係合部とによりステーに対してバンパずれ止め板が車両前後方向でずれないようにでき、かつ、固定部によりバンパずれ止め板に対してバンパ部が少なくとも車両前後方向でずれないようにできる。 According to the above configuration, by interposing the bumper anti-slip plate between the bumper portion and the retaining portion, the fastening member and the engaging portion prevent the bumper anti-slip plate from shifting relative to the stay in the vehicle's longitudinal direction, and the fixing portion prevents the bumper portion from shifting relative to the bumper anti-slip plate, at least in the vehicle's longitudinal direction.
また、前記バンパ部が丸パイプ材から構成され、前記締結部材がＵボルトであり、前記バンパずれ止め板は、前記バンパ部の外周面に沿う曲率を有する湾曲板から構成され、前記バンパ部と前記押さえ部との間に介在させた際の、前記バンパ部が延びる方向に交差する方向での少なくとも一端部に、前記係合部としての切欠を有するものとできる。 Furthermore, the bumper portion may be made of round pipe material, the fastening member may be a U-bolt, and the bumper anti-slip plate may be made of a curved plate having a curvature along the outer circumferential surface of the bumper portion, and may have a notch as the engaging portion at at least one end in a direction intersecting the direction in which the bumper portion extends when interposed between the bumper portion and the retaining portion.
前記構成によれば、汎用的な構成でバンパ部のずれ止めを実現できる。 According to the above configuration, bumper slippage can be prevented with a general-purpose setup.
また、前記バンパずれ止め板は、前記固定部として、ねじまたはリベットが貫通する貫通穴を有するものとできる。 Furthermore, the bumper anti-slip plate may have through holes through which screws or rivets pass, serving as the fixing portion.
前記構成によれば、バンパずれ止め板とバンパ部との固定を容易に行える。 According to the above configuration, the bumper anti-slip plate and the bumper portion can be easily fixed together.
また、前記バンパ部は、車両前後方向に延びるように設けられ、前記バンパずれ止め板は、前記バンパ部と前記押さえ部との間に介在させた際に、車両前後方向で前端部の上下寸法が、後端部の上下寸法よりも小さく形成されており、かつ、上下寸法が小さく形成された部分に前記貫通穴が形成されているものとできる。 Furthermore, the bumper portion is provided to extend in the longitudinal direction of the vehicle, and when the bumper anti-slip plate is interposed between the bumper portion and the retaining portion, the vertical dimension of the front end in the longitudinal direction of the vehicle is formed to be smaller than the vertical dimension of the rear end, and the through hole is formed in the portion where the vertical dimension is smaller.
前記構成によれば、バンパずれ止め板の前端部で、貫通穴から離れた部分を小さくできるため、車両走行時の物体衝突による、バンパずれ止め板の変形（めくれ等）を抑制できる。 According to the above configuration, the portion of the bumper anti-slip plate away from the through-hole at the front end can be made smaller, thereby suppressing deformation (such as peeling) of the bumper anti-slip plate caused by object collisions during vehicle operation.
また本発明の構成の一つは、車両の周囲部分に設けられるバンパ構造に適用されるバンパずれ止め板であって、前記バンパ構造は、前記車両の本体に取り付けられるステーと、丸パイプ材から構成され、前記ステーに交差して設けられたバンパ部と、前記ステーに対して前記バンパ部を前記交差した状態で保持するＵボルトと、を備え、前記バンパ部と前記押さえ部との間に介在し、前記バンパ部の外周面に沿うように配置され、板状体から構成され、前記Ｕボルトが係合する切欠と、前記バンパ部をねじまたはリベットにより固定する貫通穴と、を備えるバンパずれ止め板である。 Furthermore, one configuration of the present invention is a bumper slip prevention plate applied to a bumper structure provided on the periphery of a vehicle. The bumper structure comprises a stay attached to the vehicle body, a bumper portion made of a round pipe material and intersecting the stay, and a U-bolt that holds the bumper portion in the intersecting position relative to the stay. The bumper slip prevention plate is interposed between the bumper portion and the retaining portion, arranged along the outer circumferential surface of the bumper portion, and is made of a plate-like body. It includes a notch into which the U-bolt engages and a through-hole for fixing the bumper portion with screws or rivets.
前記構成によれば、バンパずれ止め板をバンパ部と押さえ部との間に介在させることで、締結部材と係合部とによりステーに対してバンパずれ止め板が車両前後方向でずれないようにでき、かつ、固定部によりバンパずれ止め板に対してバンパ部が回転方向及び車両前後方向にずれないようにできる。従って、車体に対してバンパ部をずれないようにできる。 According to the above configuration, by interposing the bumper anti-slip plate between the bumper portion and the retaining portion, the fastening member and the engaging portion prevent the bumper anti-slip plate from shifting relative to the stay in the vehicle's longitudinal direction, and the fixing portion prevents the bumper portion from shifting relative to the bumper anti-slip plate in the rotational direction and the vehicle's longitudinal direction. Therefore, the bumper portion can be prevented from shifting relative to the vehicle body.
本発明によると、ステーに対するパイプ材の変位を抑制できる。 According to the present invention, the displacement of the pipe material relative to the stay can be suppressed.
次に、本発明につき一実施形態を取り上げて説明を行う。なお、以下における前後と上下の表現は、車両に配置された場合の方向に対応する。また、内外の表現は、車幅方向で車両の中心から遠い方を外方とする。なお、丸パイプ材に関しては、径方向の内外を示すことにも用いる。 Next, we will describe one embodiment of the present invention. In the following, the terms "front/back" and "up/down" correspond to the direction when the object is positioned on a vehicle. Furthermore, the terms "inside" and "outside" refer to the direction furthest from the vehicle's center in the vehicle width direction. For round pipe materials, these terms are also used to indicate the inside and outside in the radial direction.
本実施形態は、図示しない車両（例えば荷役車両や特装車両）の周囲部分、特にタイヤの車幅方向での側方や前後に設けられるバンパ構造である。このバンパ構造は車両側方の「サイドバンパ」に適用することができる。また、車両後方の「リアバンパ」に適用することもできる。図１、図２に示すように、バンパ構造は主に、ステー１、バンパ部２、締結部材３、バンパずれ止め板４、をそれぞれ備える。 This embodiment describes a bumper structure provided on the periphery of a vehicle (e.g., a cargo handling vehicle or a special-purpose vehicle), particularly on the sides and front/rear in the vehicle width direction relative to the tires. This bumper structure can be applied to the "side bumper" on the side of the vehicle. It can also be applied to the "rear bumper" at the rear of the vehicle. As shown in Figures 1 and 2, the bumper structure mainly comprises a stay 1, a bumper section 2, a fastening member 3, and a bumper anti-slip plate 4.
ステー１は、車両の本体（具体的にはサブフレーム）に取り付けられ、上下方向に延びる垂下部１１を有する。ステー１の基端部及び下部には、車両側に取り付けるための、鋼材等からなる取付補助部材Ｘが連結されている。ステー１は、バンパ部２を支持するため、車両の側面や後面の一面当たりで、間隔を空けて２本以上が設けられる（図１ではそのうち１本を示している）。本実施形態のステー１は曲げ加工された丸パイプ材から構成されている。 The stay 1 is attached to the vehicle's main body (specifically, the subframe) and has a vertically extending hanging portion 11. Mounting auxiliary members X, made of steel or the like, are connected to the base and lower ends of the stay 1 for attachment to the vehicle. Two or more stays 1 are provided at intervals on each side or rear surface of the vehicle to support the bumper portion 2 (Figure 1 shows one of them). In this embodiment, the stay 1 is made from a bent round pipe.
バンパ部２は、１本以上の棒状体、具体的には中空のパイプ材から構成され、ステー１の垂下部１１に交差して設けられる。なお、バンパ部２は中実の棒状体から構成されていてもよい。本実施形態のバンパ部２は、複数（具体的には３本）の同一長さの丸パイプ材から構成されている。しかしこれに限定されず、角パイプから構成することもできる。バンパ部２はステー１に対して車幅方向外方で直交して設けられる。このため、バンパ部２のうちステー１に直交する部分は、車両前後方向（図１の左右方向）に延びている。図２に示すように、バンパ部２はステー１に対して当接している。なお、場合によっては板状体やクッション材が介在してもよい。また、複数の丸パイプ材は、図１に示すように上下で等間隔かつ平行に配置されている。 The bumper section 2 is composed of one or more rod-shaped bodies, specifically hollow pipes, and is provided intersecting the hanging portion 11 of the stay 1. The bumper section 2 may also be composed of solid rod-shaped bodies. In this embodiment, the bumper section 2 is composed of multiple (specifically three) round pipes of the same length. However, it is not limited to this and can also be composed of square pipes. The bumper section 2 is provided perpendicular to the stay 1 in the outward direction of the vehicle width. Therefore, the portion of the bumper section 2 perpendicular to the stay 1 extends in the front-rear direction of the vehicle (left-right direction in Figure 1). As shown in Figure 2, the bumper section 2 is in contact with the stay 1. In some cases, a plate-like body or cushioning material may be interposed. Furthermore, the multiple round pipes are arranged equally spaced and parallel to each other vertically, as shown in Figure 1.
締結部材３は、ステー１に対してバンパ部２を前記交差した状態で保持するための部材である。締結部材３は、バンパ部２の車幅方向での外方に位置してバンパ部２をステー１に対して当接させる押さえ部３１と、押さえ部３１から突出しステー１を貫通してステー１に固定される貫通棒３２と、を備える。このため、ステー１には径方向に貫通する貫通穴が形成されている。本実施形態の締結部材３はＵボルトである。押さえ部３１はＵボルト３の湾曲部分に該当し、貫通棒３２はＵボルト３のねじ棒部分に該当する。図２に示すように、貫通棒３２に形成されているねじに、車幅方向内方からナットＮがねじ込まれることで、Ｕボルト３がステー１に固定される。 The fastening member 3 is a member for holding the bumper portion 2 in the intersecting position relative to the stay 1. The fastening member 3 comprises a pressing portion 31 located outward in the vehicle width direction of the bumper portion 2 to bring the bumper portion 2 into contact with the stay 1, and a through-rod 32 protruding from the pressing portion 31, passing through the stay 1, and being fixed to the stay 1. Therefore, a through-hole is formed in the stay 1, penetrating in the radial direction. In this embodiment, the fastening member 3 is a U-bolt. The pressing portion 31 corresponds to the curved portion of the U-bolt 3, and the through-rod 32 corresponds to the threaded portion of the U-bolt 3. As shown in Figure 2, the U-bolt 3 is fixed to the stay 1 by screwing a nut N onto the thread formed on the through-rod 32 from the inside in the vehicle width direction.
バンパずれ止め板４は、ステー１に対するバンパ部２のずれを抑制する部材である。バンパずれ止め板４は、バンパ部２と締結部材３の押さえ部３１との間に介在し、バンパ部２の外周面に沿う板状体である。バンパずれ止め板４は、例えばステンレス板等の、横長の金属板で構成されている。バンパずれ止め板４は、締結部材（Ｕボルト）３の貫通棒３２が係合する係合部４１と、バンパ部２を固定する固定部４２と、を備える。バンパずれ止め板４は、図２、図３（Ａ）に示すように、バンパ部２を構成する丸パイプ材の外周面に沿う曲率とされた内面４３を有する湾曲板から構成されている。内面４３の曲率は、バンパずれ止め板４の長手方向で一定とされている。このため、バンパずれ止め板４をガタつくことなく、バンパ部２における各丸パイプの外周面に沿わせることができる。 The bumper anti-slip plate 4 is a member that suppresses the displacement of the bumper portion 2 relative to the stay 1. The bumper anti-slip plate 4 is interposed between the bumper portion 2 and the pressing portion 31 of the fastening member 3, and is a plate-like body that follows the outer circumferential surface of the bumper portion 2. The bumper anti-slip plate 4 is made of a horizontally elongated metal plate, such as a stainless steel plate. The bumper anti-slip plate 4 includes an engaging portion 41 into which the through-rod 32 of the fastening member (U-bolt) 3 engages, and a fixing portion 42 for fixing the bumper portion 2. As shown in Figures 2 and 3(A), the bumper anti-slip plate 4 is made of a curved plate having an inner surface 43 with a curvature that follows the outer circumferential surface of the round pipe material constituting the bumper portion 2. The curvature of the inner surface 43 is constant in the longitudinal direction of the bumper anti-slip plate 4. Therefore, the bumper anti-slip plate 4 can be positioned along the outer circumferential surface of each round pipe in the bumper portion 2 without rattling.
バンパずれ止め板４は、図３（Ｂ）に示すように、バンパ部２と押さえ部３１との間に介在させた際の、前記バンパ部２が延びる方向に交差する方向での少なくとも一端部に、前記係合部としての切欠４１を有する。本実施形態の切欠４１は、バンパずれ止め板４の前記介在させた際の上下端部に形成されている。このように切欠４１を形成することにより、汎用的な構成でバンパ部２のずれ止めを実現できる。切欠４１は、図２に示すように、Ｕボルト３の貫通棒３２としてのねじ棒部分が入り込む。このため切欠４１は、バンパ部２への配置状態で上下に対向するように一対形成されている。Ｕボルト３はステー１に強固に固定されているため、バンパずれ止め板４はＵボルト３によって車両前後方向への移動が制限される。これは、具体的には、切欠４１の前側端面または後側端面にＵボルト３の外周面が接触することでなされる。また、Ｕボルト３の締付力により、Ｕボルト３、バンパずれ止め板、バンパ部２のそれぞれの間で摩擦力が働くことでなされる。このため、ステー１に対してのずれ止めがなされる。 As shown in Figure 3(B), the bumper anti-slip plate 4 has a notch 41 as an engaging portion at at least one end in a direction intersecting the direction in which the bumper portion 2 extends when interposed between the bumper portion 2 and the retaining portion 31. In this embodiment, the notch 41 is formed at the upper and lower ends of the bumper anti-slip plate 4 when it is interposed. By forming the notch 41 in this way, anti-slip of the bumper portion 2 can be achieved with a general-purpose configuration. As shown in Figure 2, the threaded portion of the U-bolt 3 as the through rod 32 fits into the notch 41. For this reason, a pair of notches 41 are formed so as to face each other vertically when positioned on the bumper portion 2. Since the U-bolt 3 is firmly fixed to the stay 1, the movement of the bumper anti-slip plate 4 in the vehicle's longitudinal direction is restricted by the U-bolt 3. Specifically, this is achieved by the outer circumferential surface of the U-bolt 3 contacting the front or rear end surface of the notch 41. Furthermore, the tightening force of the U-bolt 3 creates frictional forces between the U-bolt 3, the bumper anti-slip plate, and the bumper section 2. This prevents slippage relative to the stay 1.
本実施形態では、切欠４１を挟む長手方向両側方に、内面４３よりも曲率が小さいか、または平板状とされた切欠周囲部４５が形成されている。図２に示すように、切欠周囲部４５はバンパ部２における各丸パイプに沿わず、各丸パイプの径外位置に配置される。つまり切欠周囲部４５は、貫通棒３２に対して車両前後方向で引っ掛かりが生じる位置に配置される。このため、バンパずれ止め板４の車両前後方向への移動がより効果的に制限される。 In this embodiment, a notch perimeter portion 45 is formed on both longitudinal sides of the notch 41, having a curvature smaller than the inner surface 43 or being flat. As shown in Figure 2, the notch perimeter portion 45 is not aligned with each round pipe in the bumper portion 2, but is positioned outside the diameter of each round pipe. In other words, the notch perimeter portion 45 is positioned to catch on the through rod 32 in the vehicle's longitudinal direction. Therefore, the movement of the bumper anti-slip plate 4 in the vehicle's longitudinal direction is more effectively restricted.
バンパずれ止め板４は、前記固定部として、ねじまたはリベットが貫通する貫通穴４２を有する。本実施形態では貫通穴４２は真円形状で１個であるが、形状や数量は適宜変更できる。また貫通穴４２は、バンパ部２への配置状態で水平方向に貫通している。なお、ねじにはボルトが含まれる。貫通穴４２を通るねじまたはリベット（図示しない）はバンパ部２に固定される。前述のように、ステー１に対してずれ止めがなされているバンパずれ止め板４とバンパ部２とが、ねじまたはリベットで固定されるため、バンパ部２についてもステー１に対してのずれ止めがなされる。このバンパずれ止め板４によるずれ止めは、バンパ部２が丸パイプ材から構成されている場合、車両前後方向及び回転方向の両方に作用する。また、バンパ部２が角パイプ材（例えば断面形状が長方形や正方形）から構成されている場合、バンパ部２の断面形状により回転方向のずれが起こらないため、バンパずれ止め板４によるずれ止めは、車両前後方向に作用する。 The bumper anti-slip plate 4 has a through-hole 42 through which a screw or rivet passes, serving as the fixing portion. In this embodiment, the through-hole 42 is circular and single, but its shape and number can be changed as appropriate. The through-hole 42 penetrates horizontally when positioned on the bumper portion 2. Note that screws include bolts. The screw or rivet (not shown) passing through the through-hole 42 is fixed to the bumper portion 2. As described above, since the bumper anti-slip plate 4, which prevents slippage relative to the stay 1, and the bumper portion 2 are fixed together with screws or rivets, the bumper portion 2 is also prevented from slipping relative to the stay 1. This slip prevention by the bumper anti-slip plate 4 acts in both the longitudinal and rotational directions of the vehicle when the bumper portion 2 is made of round pipe material. Furthermore, when the bumper portion 2 is made of square pipe material (for example, with a rectangular or square cross-section), rotational slippage does not occur due to the cross-sectional shape of the bumper portion 2, so the slip prevention by the bumper anti-slip plate 4 acts in the longitudinal direction of the vehicle.
バンパずれ止め板４は、図３（Ｂ）に示すように、バンパ部２と押さえ部との間に介在させた際に、車両前後方向で前端部の上下寸法が、後端部の上下寸法よりも小さく形成されており、かつ、上下寸法が小さく形成された部分（絞り部４４）に貫通穴４２が形成されている。絞り部４４は車幅方向から見た場合、横倒しの台形状とされている。バンパずれ止め板４をこのような形状とすることで、バンパずれ止め板４の前端部で、貫通穴４２から離れた部分を小さくできるため、車両走行時の物体衝突（例えば物体の擦れ）による、バンパずれ止め板４の変形（めくれ等）を抑制できる。 As shown in Figure 3(B), when the bumper anti-slip plate 4 is interposed between the bumper portion 2 and the retaining portion, the vertical dimension of the front end in the vehicle's longitudinal direction is smaller than the vertical dimension of the rear end, and a through hole 42 is formed in the portion where the vertical dimension is smaller (the constricted portion 44). When viewed from the vehicle width direction, the constricted portion 44 has a horizontally tilted trapezoidal shape. By giving the bumper anti-slip plate 4 this shape, the portion of the front end of the bumper anti-slip plate 4 away from the through hole 42 can be made smaller, thus suppressing deformation (such as peeling) of the bumper anti-slip plate 4 due to object collisions (e.g., friction) during vehicle operation.
以上のように構成された本実施形態によれば、バンパずれ止め板４をバンパ部２と押さえ部との間に介在させることで、締結部材３と係合部とによりステー１に対してバンパずれ止め板４が車両前後方向でずれないようにでき、かつ、固定部によりバンパずれ止め板４に対してバンパ部２がずれないようにできる。特に、バンパ部２が丸パイプ材から構成されている場合は、固定部によりバンパずれ止め板４に対してバンパ部２が回転方向及び車両前後方向にずれないようにできる。 As described above, in this embodiment, by interposing the bumper anti-slip plate 4 between the bumper portion 2 and the retaining portion, the fastening member 3 and the engaging portion prevent the bumper anti-slip plate 4 from shifting relative to the stay 1 in the vehicle's longitudinal direction, and the fixing portion prevents the bumper portion 2 from shifting relative to the bumper anti-slip plate 4. In particular, if the bumper portion 2 is made of a round pipe material, the fixing portion prevents the bumper portion 2 from shifting relative to the bumper anti-slip plate 4 in both the rotational and vehicle's longitudinal directions.
以上、本発明につき一実施形態を取り上げて説明したが、本発明は前記実施形態に限定されない。 Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.
例えば、前記実施形態では、ステー１が上下方向に延びる垂下部１１を有するものとされ、バンパ部２はステー１の垂下部１１に交差して、車両前後方向に延びるように設けられていた。しかしこれ以外に、ステー１が車両前後方向に延びる部分を有し、この部分にバンパ部２が交差して、上下方向に延びるように設けられていてもよい（図示しない）。この場合バンパずれ止め板４は、前記実施形態に対して９０度回転した状態で取り付けられることになる。 For example, in the above embodiment, the stay 1 has a hanging portion 11 extending in the vertical direction, and the bumper portion 2 is provided to intersect the hanging portion 11 of the stay 1 and extend in the vehicle's longitudinal direction. However, the stay 1 may also have a portion extending in the vehicle's longitudinal direction, and the bumper portion 2 may be provided to intersect this portion and extend in the vertical direction (not shown). In this case, the bumper anti-slip plate 4 would be mounted rotated 90 degrees relative to the above embodiment.
また、バンパずれ止め板４の内面４３は、前記実施形態では、バンパ部２を構成する丸パイプ材の外周面に沿う曲率とされていた。つまり、内面４３の曲率は丸パイプ材の外周面の曲率に略一致していた。しかし、これに限定されず、内面４３の曲率は丸パイプ材の外周面の曲率よりも大きくても小さくてもよい。特に前者の場合は、内面４３のうち２か所でバンパ部２と接するようにでき、バンパ部２とバンパずれ止め板４の摩擦を大きくできる。 Furthermore, in the above embodiment, the inner surface 43 of the bumper anti-slip plate 4 had a curvature that followed the outer surface of the round pipe material constituting the bumper portion 2. That is, the curvature of the inner surface 43 approximately matched the curvature of the outer surface of the round pipe material. However, it is not limited to this; the curvature of the inner surface 43 may be greater or less than the curvature of the outer surface of the round pipe material. In particular, in the former case, the inner surface 43 can be made to contact the bumper portion 2 at two points, thereby increasing the friction between the bumper portion 2 and the bumper anti-slip plate 4.
