(1) Assemble the shock absorber A to the suspension member.
(2) The coil spring 52 is extrapolated from above to the cylinder tube 60 of the shock absorber, and the lower end portion of the coil spring 52 is placed on a flange-like spring receiver 61 formed on the cylinder tube 60 so as to be coiled by a pressing tool or the like. The spring 52 is compressed.
To do.
(3) The strut mount 100 is arranged above the rod R of the shock absorber so that the upper ends of the coil springs 52 are received by the mounting flanges 11 and 14 of the strut mount 100 and the upper end of the rod R is attached to the inner cylinder fitting 1. The fitting portion 50 of the rod R is fitted into the fitting hole 30 of the inner cylinder fitting 1.
(4) The nut 54 is screwed into the male screw portion formed on the upper end side of the rod R. As a result, the strut mount 100 is assembled to the suspension member.
(5) A plurality of engaging portions of the mounting cone 25 are individually engaged with a plurality of engaging holes of the rebound stopper, whereby the mounting cone 25 is mounted on the rebound stopper 7, and the vehicle body F, the suspension member, and the strut mount 100 is relatively moved up and down. At this time, the upper-constricted mounting cone 25 is guided through the strut mount insertion hole 51 on the vehicle body side, and the upper end portion of the strut mount 100 is smoothly inserted into the strut mount insertion hole 51. That is, the mounting cone 25 is a component for smoothly inserting the upper end portion of the strut mount 100 into the strut mount insertion hole 51.

前述のようにロッドの嵌合部は、断面形状がＤ字形や小判形などの非円形状に形成されて直線状の嵌合面を備え、内筒金具の嵌合孔もＤ字形や小判形などの非円形状に形成されて直線状の被嵌合面を備えていることから、上記の（３）の工程では、作業者が内筒金具の嵌合孔の被嵌合面を観察しながらストラットマウントをロッドに対して周方向で位置を合わせなければならない。ところが、内筒金具の嵌合孔は内筒金具の下方の底に形成されており、そのうえ、サスペンションメンバーから立ち上がったショックアブソーバーの上端部付近の高所に前記内筒金具を位置させて作業するために、作業者から嵌合孔が見えにくかった。そこで従来、リバウンドストッパの上面にペンキで目印を付け、平面視において、前記被嵌合面と直交する方向で、前記目印と、前記嵌合孔の被嵌合面とを並んで位置させていた。これにより、見えにくい嵌合孔の被嵌合面を観察しなくても前記目印を観察することで、被嵌合面と直交する方向をすぐに識別でき、ストラットマウントをロッドに対して周方向で位置を合わせ、ロッドの嵌合部と内筒金具の嵌合孔とを嵌合させることができる。 As described above, the fitting portion of the rod is formed in a non-circular shape such as a D-shape or an oval cross-sectional shape and has a linear fitting surface, and the fitting hole of the inner cylinder fitting is also a D-shape or an oval shape. In the process (3), the operator observes the mating surface of the mating hole of the inner cylinder fitting, because the mating surface is formed in a non-circular shape. However, the strut mount must be aligned with the rod in the circumferential direction. However, the fitting hole of the inner cylinder fitting is formed in the bottom below the inner cylinder fitting, and the inner cylinder fitting is positioned at a high position near the upper end of the shock absorber rising from the suspension member. Therefore, it was difficult for the operator to see the fitting hole. Therefore, conventionally, a mark is provided on the upper surface of the rebound stopper with a paint, and the mark and the fitted surface of the fitting hole are positioned side by side in a direction orthogonal to the fitted surface in a plan view. . This makes it possible to immediately identify the direction orthogonal to the mating surface by observing the mark without observing the mating surface of the mating hole which is difficult to see, and the strut mount in the circumferential direction with respect to the rod. The position can be adjusted by fitting the fitting portion of the rod and the fitting hole of the inner cylinder fitting.

しかしながら上記従来の手段によれば、リバウンドストッパの上面に作業者がいちいちペンキを塗布しなければならず、作業工程が増えるとともにペンキの塗布作業に手間がかかって製作コストが高くなるという問題があった。 However, according to the conventional means, there is a problem that an operator has to apply paint to the upper surface of the rebound stopper one by one, which increases the work process and takes time to apply the paint, which increases the manufacturing cost. It was.

本発明の目的は、製作コストを低廉化できるストラットマウントを提供する点にある。 An object of the present invention is to provide a strut mount that can reduce the manufacturing cost.

本発明の特徴は、
ショックアブソーバーのロッドが挿通嵌合されて連結される内筒金具と、車体側に取付けられる外筒金具と、前記内筒金具と外筒金具を連結するゴム状弾性体と、前記内筒金具の筒部の上端部から前記外筒金具の筒部の上方側に張り出すリバウンドストッパと、前記外筒金具の筒部から径方向外方側に張り出す取付けフランジとを備え、前記ロッドの嵌合部を嵌合させる前記内筒金具の嵌合孔の内周部に、前記嵌合部に形成された直線状の嵌合面を嵌合させる直線状の被嵌合面が形成され、前記車体への組付けの際に前記車体側のストラットマウント挿通孔に挿通案内される上窄まりの搭載コーンを搭載する搭載部が前記リバウンドストッパに設けられるとともに、前記リバウンドストッパに、前記搭載コーンの下端部側の複数の係合部を各別に係合させる複数の係合孔が形成されているストラットマウントであって、
平面視において、前記嵌合孔の被嵌合面と、前記複数の係合孔のうちの一つの係合孔とが前記被嵌合面と直交する方向に並んで位置し、前記一つの係合孔の内周面に凹部が形成されている点にある。 The feature of the present invention is that
An inner cylinder fitting to which a rod of a shock absorber is inserted and fitted, an outer cylinder fitting attached to the vehicle body side, a rubber-like elastic body connecting the inner cylinder fitting and the outer cylinder fitting, and an inner cylinder fitting The rod fitting includes a rebound stopper that projects from the upper end portion of the tubular portion to the upper side of the tubular portion of the outer tubular fitting, and a mounting flange that projects radially outward from the tubular portion of the outer tubular fitting. A linear mating surface for mating a linear mating surface formed in the mating portion is formed on the inner peripheral portion of the mating hole of the inner cylinder fitting for mating the portion, and the vehicle body A mounting portion for mounting a constricted mounting cone that is inserted and guided through the strut mount insertion hole on the vehicle body side when assembled to the vehicle body is provided on the rebound stopper, and the lower end of the mounting cone is mounted on the rebound stopper. A plurality of engaging parts on the side A strut mount a plurality of engaging holes for engaging is formed,
In plan view, the mating surface of the mating hole and one of the plurality of engaging holes are aligned in a direction orthogonal to the mating surface, and the one engagement The recess is formed in the inner peripheral surface of the joint hole.

この構成によれば、平面視において、前記嵌合孔の被嵌合面と、前記複数の係合孔のうちの一つの係合孔とが前記被嵌合面と直交する方向に並んで位置し、前記一つの係合孔の内周面に凹部が形成されているから、被嵌合面と直交する方向を前記凹部を観察することで判別することができる。凹部は内筒金具の上端部側のリバウンドストッパに形成されており、作業者から見やすい位置にあることから凹部をすぐに観察することができる。これにより、ストラットマウントをロッドに対して周方向で位置を合わせて、ロッドの嵌合部と内筒金具の嵌合孔とを嵌合させることができる。また、係合孔を形成するときに凹部を形成できて、凹部を形成するための専用の工程を設ける必要がない。凹部は係合孔の内周部に形成してあるから、例えば、前記凹部に換えてリバウンドストッパの外周縁部に、前記被嵌合面と直交する方向を識別するための切欠きを形成してある構造に比べると、リバウンドストッパの強度が低下する不具合を回避することができる。 According to this configuration, in a plan view, the fitted surface of the fitting hole and one engaging hole of the plurality of engaging holes are aligned in a direction orthogonal to the fitted surface. And since the recessed part is formed in the internal peripheral surface of said one engagement hole, the direction orthogonal to a to-be-fitted surface can be discriminate | determined by observing the said recessed part. The concave portion is formed in the rebound stopper on the upper end side of the inner cylinder fitting, and the concave portion can be observed immediately because it is in a position that is easy to see from the operator. Thus, the strut mount can be aligned with the rod in the circumferential direction, and the fitting portion of the rod and the fitting hole of the inner cylinder fitting can be fitted. Further, when forming the engagement hole, the recess can be formed, and there is no need to provide a dedicated process for forming the recess. Since the concave portion is formed in the inner peripheral portion of the engagement hole, for example, a notch for identifying the direction orthogonal to the mating surface is formed in the outer peripheral edge portion of the rebound stopper instead of the concave portion. Compared to the existing structure, the problem that the strength of the rebound stopper is reduced can be avoided.

前記係合孔が前記内筒金具の周方向に沿う円弧状に形成され、前記周方向における前記一つの係合孔の中央部に前記凹部が位置していると、係合孔の周りのリバウンドストッパ部分に力が集中しにくくなって、リバウンドストッパの強度の低下を防止できる。 In the present invention,
When the engagement hole is formed in an arc shape along the circumferential direction of the inner cylinder fitting, and the recess is located at the center of the one engagement hole in the circumferential direction, the rebound around the engagement hole It becomes difficult for the force to concentrate on the stopper part, and the strength of the rebound stopper can be prevented from being lowered.

本発明において、
平面視において、前記嵌合孔の軸芯と、前記被嵌合面の中心と、前記一つの係合孔の中心と、前記凹部の幅方向の中心とが一直線状に並んでいる構成にすることができる。この構成によれば、前記凹部を観察することで被嵌合面と直交する方向をより判別しやすくなる。 In the present invention,
In plan view, the shaft core of the fitting hole, the center of the mating surface, the center of the one engaging hole, and the center in the width direction of the recess are arranged in a straight line. be able to. According to this structure, it becomes easier to distinguish the direction orthogonal to the mating surface by observing the recess.

本発明において、
前記凹部が円弧状に形成されていると、凹部の周りのリバウンドストッパ部分に力が集中しにくくなって、リバウンドストッパの強度の低下を防止できる。 In the present invention,
