- the telescopic rocking friction plate 25 swings around the support pin 33. That is, when the outer column 13a is displaced forward, the adjusting rod 22a is displaced along the telescopic long hole 19a and the guide long hole 32 from the state shown in FIG. 5 to the state shown in FIG.

- the length direction of the guide slot 32 and the length direction of the telescopic slot 19a remain non-parallel and do not coincide with each other in the entire range of the swing. It is like that.
- the distance between the adjustment nut 29 and the head 30 is reduced by swinging the adjustment handle 23 in a direction opposite to a predetermined direction (generally upward). Thereby, the surface pressure of the contact portion between the outer side surface of the support plate portion 20a and the inner side surface of the adjustment nut 29 and the inner side surface of the head 30 is increased, and the steering wheel 1 is held at the adjusted position.
- the holding force of the outer column 13a with respect to the support bracket 12a is the steering wheel with respect to the support bracket 12a.
- the holding force of the outer bracket 13a on the support bracket 12a particularly the holding force in the front-rear direction (the axial direction of the outer column 13a). It effectively functions as a friction surface.

- the side surfaces on both sides of the telescopic rocking friction plate 25, the inner surface of the support plate portion 20a, and the outer surface of the displacement bracket 18a are used. It is not sufficient to cause only one of the abutting portions to slip, and it is necessary to cause both of the abutting portions to slip. Therefore, both of these contact portions effectively function as friction surfaces for securing the holding force in the front-rear direction.
- the number of friction surfaces is reduced.
- the number can be increased by one for each place where the telescopic rocking friction plate 25 is installed.
- the holding force in the front-rear direction can be improved accordingly.

- the holding force related to the adjustment direction of the front-rear position can be ensured.
- the contact portions between the side surfaces on both sides of the telescopic rocking friction plate 25 and the outer surface of the support plate portion 20a of the support bracket 12a become contact portions of surfaces having different hardnesses. For this reason, with the occurrence of a secondary collision, when the slip tends to occur in the contact portions of the surfaces having different hardness, the surface on the high hardness side bites into the surface on the low hardness side, It is possible to prevent slippage at the contact portion. This also secures the holding force related to the adjustment direction of the front-rear position among the holding force of the outer column 13a with respect to the support bracket 12a.
- the oscillating friction plates 25 are arranged on both the left and right sides of the outer column 13a, but can be arranged only on one side in the left-right direction.

- the swing friction plate 34 swings around the support pin 37 in the clockwise direction of FIGS. 6 and 8. As a result, the adjustment rod 22a and the support pin 37 are relatively displaced in a direction away from each other.
- the distance between the adjustment nut 29 and the head 30a is reduced by swinging the adjustment handle 23 in the direction opposite to the predetermined direction. Thereby, the surface pressure of the fitting portion between the inner peripheral surface of the front end portion of the outer column 13a and the outer peripheral surface of the rear end portion of the inner column 14a is increased, and the steering wheel 1 is held at the adjusted position.
- both side surfaces of the tilting oscillating friction plate 34, the outer surface of the support plate portion 20a, the inner surface of the adjusting nut 29, and The contact portions with the inner side surface of the head 30a effectively function as a friction surface for securing the holding force in the vertical direction among the holding force of the outer column 13a with respect to the support bracket 12a.

Abstract
Description
図1~図5は、本発明の実施の形態の第1例を示している。本例のステアリング装置は、ステアリングコラム6aと、ステアリングシャフト5aと、テレスコピック用長孔19aと、支持ブラケット12aと、チルト用長孔21aと、拡縮装置24と、1対のテレスコピック用揺動摩擦板25とを備える。
図6~図8は、本発明の実施の形態の第2例を示している。本例の場合、実施の形態の第1例の構造と異なり、支持ブラケット12aを構成する1対の支持板部20aの内側面と、変位ブラケット18aの両側の外側面との間には、テレスコピック用揺動摩擦板を設置せず、これらの側面同士を直接当接させている。その代わりに、本例の場合には、支持板部20aの外側面と調節ナット29の内側面および支持板部20aの外側面と調節杆22aの頭部30aの内側面との間に、それぞれチルト用揺動摩擦板34を1枚ずつ挟持している。
図9は、本発明の実施の形態の第3例を示している。本例の場合、チルト用揺動摩擦板34を、支持板部20aの内側面と、アウタコラム13aの被狭持板部27の外側面との間部分に狭持している。その他の構成および作用は、実施の形態の第2例と同様である。
図10~図12は、本発明の実施の形態の第4例を示している。本例は、実施の形態の第1例および第2例を組み合わせた構造を有する。すなわち、支持板部20aの内側面と被狭持板部27の外側面との間にテレスコピック用揺動摩擦板25を、支持板部20aの外側面と調節ナット29の内側面の間および支持板部20aの外側面と調節杆22aの頭部30aの内側面との間にチルト用揺動摩擦板34を、それぞれ狭持している。このような構造により、支持ブラケット12aに対するアウタコラム13aの保持力を、上下方向および前後方向について確保することができる。その他の構成および作用は、実施の形態の第1例および第2例と同様である。
図13は、本発明の実施の形態の第5例を示している。本例は、特開2010-52639号公報に記載の構造に、本発明を適用した構造を有する。すなわち、チルト用長孔21bの、ステアリングコラム6aの中心軸に対し直交する仮想平面αに対する傾斜角度βを、ステアリングホイール1(図41参照)の上下位置にかかわらず、ステアリングコラム6aの中心軸の前後方向γに対する傾斜角度δよりも大きくしている。このため、二次衝突時にステアリングホイール1に加わる前方に向いた衝撃荷重に基づき、調節杆22aをチルト用長孔21bの前下方に変位させようとする分力が、調節杆22aをチルト用長孔21bの後上方に変位させようとする分力よりも確実に大きくなる。この結果、アウタコラム13aが舞い上がることが防止されて、ステアリングホイール1と運転者の身体が衝突する位置を適正にできる。その他の部分の構成および作用は、実施の形態の第1例と同様である。
図14~図16は、本発明の実施の形態の第6例を示している。本例の場合には、テレスコピック用揺動摩擦板25aに形成する揺動中心孔31と案内長孔32aとのうち、案内長孔32aを円弧状にするとともに、これらの揺動中心孔31と案内長孔32aとを、同一円弧上に配置している。これに合わせて、テレスコピック用揺動摩擦板25aを円弧形としている。このような構成を採用することにより、ステアリングホイール1(図41参照)の前後位置の調節時における、調節杆22aを中心とするテレスコピック用揺動摩擦板25aの揺動を、より円滑に行わせることができる。
図17~図19は、本発明の実施の形態の第7例を示している。本例の場合、チルト用揺動摩擦板34aに形成する揺動中心孔35と案内長孔36aとのうち、この案内長孔36aを円弧状とするとともに、これら揺動中心孔35と案内長孔36aとを、同一円弧上に配置している。これに合わせて、チルト用揺動摩擦板34aを円弧形としている。これにより、ステアリングホイール1(図41参照)の上下位置の調節時における、調節杆22aを中心とするチルト用揺動摩擦板34aの揺動を、より円滑に行わせることができる。
図20および図21は、本発明の実施の形態の第8例を示している。本例の場合、チルト用揺動摩擦板34bの形状、および、案内長孔36bの形成方向を、実施の形態の第2例の場合と異ならせている。すなわち、チルト用揺動摩擦板34bの幅方向両側縁のうち、片側縁を円弧とすることで、チルト用揺動摩擦板34bの表面積を、実施の形態の第2例のチルト用揺動摩擦板34(図6参照)よりも大きくしている。これにより、支持ブラケット12aに対するアウタコラム13aの保持力のうち、上下方向に関する保持力をより大きくすることができる。その他の部分の構成および効果は、実施の形態の第2例と同様である。
図22および図23は、本発明の実施の形態の第9例を示している。本例の場合、テレスコピック用揺動摩擦板25bの形状、および、案内長孔32bの形成方向を、実施の形態の第1例の場合と異ならせている。すなわち、テレスコピック用揺動摩擦板25bを略三角形とすることで、このテレスコピック用揺動摩擦板25bの表面積を、実施の形態の第1例のテレスコピック用揺動摩擦板25よりも大きくしている。これにより、支持ブラケット12aに対するアウタコラム13aの保持力をより大きくすることができる。その他の部分の構成および効果は、実施の形態の第1例と同様である。
図24は、本発明の実施の形態の第10例を示している。本例の場合、テレスコピック用揺動摩擦板25cを略三角形とするとともに、支持ピン33をテレスコピック用長孔19aよりも前側でアウタコラム13aの上方に設けている。これにより、テレスコピック用揺動摩擦板25cのうち、支持板部20a(図1~図3参照)と被狭持板部27との間に狭持される部分の表面積を大きくしている。また、案内長孔32cを円弧とすることで、テレスコピック用揺動摩擦板25cの揺動変位を円滑にするとともに、二次衝突時に調節杆22aが案内長孔32cに沿って変位しにくくしている。その他の部分の構成および効果は、実施の形態の第1例と同様である。
図25は、本発明の実施の形態の第11例を示している。本例の場合、支持ピン33を、テレスコピック用長孔19aの前方に設けている。その他の部分の構成および効果は、実施の形態の第10例と同様である。
図26は、本発明の実施の形態の第12例を示している。本例の場合、テレスコピック用揺動摩擦板25dを、下辺を円弧とした略三角形とし、支持ピン33をテレスコピック用長孔19aの後端部の上方に設けている。これにより、ステアリングホイール1(図41参照)の前後位置にかかわらず、テレスコピック用揺動摩擦板25dの、被挟持板部27の下端縁およびアウタコラム13aの前端縁からの突出量を抑えることができて、ステアリング装置を小型化することができる。
図27は、本発明の実施の形態の第13例を示している。本例の場合、チルト用揺動摩擦板34cを略三角形とするとともに、支持ピン33を支持板部20aの下端部の前方に設けている。これにより、支持板部20aと当接するチルト用揺動摩擦板34cの表面積を大きくして、支持ブラケット12aに対するアウタコラム13aの保持力を大きくしている。また、案内長孔36cを円弧状とすることで、チルト用揺動摩擦板34cの揺動変位を円滑にするとともに、二次衝突時に調節杆22aが案内長孔36cに沿って変位しにくくしている。その他の部分の構成および効果は、実施の形態の第2例と同様である。
図28は、本発明の実施の形態の第14例を示している。本例の場合も、実施の形態の第13例と同様に、チルト用揺動摩擦板34cを略三角形とするとともに、案内長孔36cを円弧状としているが、実施の形態の第13例とは異なり、支持ピン37を支持板部20aの前上方に設けている。
図29~図33は、本発明の実施の形態の第15例を示している。本例の場合、テレスコピック用揺動摩擦板25eを略三角形として、その表面積をより大きくするとともに、テレスコピック用揺動摩擦板25eに、直線状の案内長孔32eを形成している。また、テレスコピック用揺動摩擦板25eの一部で、案内長孔32eの幅方向両側縁のうち、二次衝突時に調節杆22aからの衝撃荷重が加わる片側縁(図29~図32の下側縁)から、この案内長孔32eの幅方向片側に離隔した部分に、この案内長孔32eと平行に強度調節用長孔38を設けている。これにより、これらの案内長孔32eと強度調節用長孔38との間に、二次衝突時に案内長孔32eの片側縁に加わる衝撃荷重に基づいて、この強度調節用長孔38側に向け塑性変形可能な、ブリッジ部39を設けている。
図34~図36は、本発明の実施の形態の第16例を示している。本例の場合、チルト用揺動摩擦板34dの幅方向両側縁のうち、片側縁を円弧として、その表面積をより大きくするとともに、チルト用揺動摩擦板34dに直線状の案内長孔36dを設けている。また、チルト用揺動摩擦板34dの一部で、案内長孔36dの幅方向両側縁のうち、二次衝突時に調節杆22aからの衝撃荷重が加わる片側縁(図34~図36の上側縁)から、この案内長孔36dの幅方向片側に離隔した部分に、この案内長孔36dと並列に強度調節用長孔40を設けている。これにより、これらの案内長孔36dと強度調節用長孔40との間に、この強度調節用長孔40側に向け塑性変形可能な、ブリッジ部41を設けている。
図37は、本発明の実施の形態の第17例を示している。本例は、実施の形態の第15例および第16例を組み合わせた構造を有している。すなわち、テレスコピック用揺動摩擦板25eに強度調節用長孔38を設けることでブリッジ部39を、チルト用揺動摩擦板34dに強度調節用長孔40を設けることでブリッジ部41を、それぞれ設けている。その他の部分の構成および効果は、実施の形態の第15例および第16例と同様である。
図38および図39は、本発明の実施の形態の第18例を示している。本例の場合、テレスコピック用揺動摩擦板25fに、円弧状の案内長孔32fを設けている。また、テレスコピック用揺動摩擦板25fの一部に、案内長孔32fと並列に円弧状の強度調節用長孔38aを設けることにより、二次衝突時に塑性変形可能な円弧状のブリッジ部39aを設けている。さらに、案内長孔32fのうち、二次衝突時に調節杆22aから加わる衝撃荷重に伴って応力が集中する、長さ方向一端縁(図38の下端縁)に、切り欠き部42を設けている。このような切り欠き部42を設けることで、二次衝突時に、ブリッジ部39aを変形しやすくしている。その他の部分の構成および効果は、実施の形態の第15例と同様である。
図40は、本発明の実施の形態の第19例を示している。本例は、実施の形態の第5例および第15例を組み合わせた構造を有する。すなわち、チルト用長孔21bの、ステアリングコラム6aの中心軸に対し直交する仮想平面αに対する傾斜角度βを、ステアリングホイール1(図41参照)の上下位置にかかわらず、ステアリングコラム6aの中心軸の前後方向γに対する傾斜角度δよりも大きくするとともに、テレスコピック用揺動摩擦板25eに強度調節用長孔38を設けることでブリッジ部39を設けている。その他の部分の構造および効果は、実施の形態の第5例および第15例と同様である。
