以下本発明の実施例のその構成を図面に基づいて説明す
る。The configuration of an embodiment of the present invention will be explained below based on the drawings.
第１図は本発明の第１番目の実施例によるボールシライ
ンド１を表している。FIG. 1 shows a ball shield 1 according to a first embodiment of the invention.
２はボールスタッドで、柄部３と柄部８の先端に球状頭
部４を有し、球状頭部４は軸受部材１２内周の内周球面
部に支承されている。Reference numeral 2 denotes a ball stud, which has a spherical head 4 at the tip of a handle 3 and a handle 8, and the spherical head 4 is supported by the inner spherical surface of the inner periphery of the bearing member 12.
ソケット１１は上下に開口を有し、底部の大開口はゴム
層１４被覆の皿バネによる閉止板１３が圧入固定されて
閉鎖され、他方の上方開口１６はボールスタッド２の柄
部３を突出させると共にブーツ５により開口周囲の空間
が外部と遮へいされている。The socket 11 has openings at the top and bottom, and the large opening at the bottom is closed by press-fitting and fixing a closing plate 13 made of a disc spring covered with a rubber layer 14, and the other upper opening 16 allows the handle 3 of the ball stud 2 to protrude. At the same time, the space around the opening is shielded from the outside by the boot 5.
ブーツ５は、上方の小開口縁部７がボールスタッド柄部
３の所定位置に嵌着され、下方の大開口縁部８がソケッ
ト１１の周溝１５に嵌着している。In the boot 5, the upper small opening edge 7 is fitted into a predetermined position of the ball stud handle 3, and the lower large opening edge 8 is fitted into the circumferential groove 15 of the socket 11.
この下方の大開口縁部８の外周には、半径方向外周に開
口した環状のブーツ溝９が形成されており、その溝９に
は、第２図、第３図に示す如き平面上で渦巻く渦巻サー
クリップ１０が装着されている。An annular boot groove 9 is formed on the outer periphery of this lower large opening edge 8, and the annular boot groove 9 is opened to the outer periphery in the radial direction. A spiral circlip 10 is attached.
また上記ブーツ５は、適当な合成ゴムにより、その両開
口縁部７，８の中間部が半径方向外周に膨出した肉薄円
筒状の胴部６を有する円筒状に形成されている。The boot 5 is formed of a suitable synthetic rubber into a cylindrical shape having a thin cylindrical body portion 6 whose middle portion between the opening edges 7 and 8 bulges outward in the radial direction.
渦巻サークリップ１０は、金属まだはその他の適当な材
料によ多形成されている。The spiral circlip 10 is made of metal or other suitable material.

でその外表面２８に亀裂が生じることはない。As shown in FIG. 4, which is an enlarged view of part A in FIG. It is formed in a substantially arc shape. Therefore, even if the inner corner 23 is pressed strongly against the outer surface 28 of the boot 5 due to the force exerted by a larger tightening force than in the past, the inner corner 23 will not dig into the outer surface 28 of the boot 5. No cracks occur on its outer surface 28.

とができる。Further, as shown in FIG. 2, a compression portion 25 is formed at the outer circumferential end 21 of the spiral circlip 10, which curves in the inner diameter direction to compress the adjacent intermediate portion 27 in the inner diameter direction. ing. In order to effectively exert the compression force in the inner diameter direction of the compression part 25, a compression part introduction part 24 is formed on the opposite end 26 side continuous with the compression part 25 and curved in the outer diameter direction. Therefore, as shown in FIG. 3, when attached to the ball cylinder, the outer peripheral end formed by these exerts a high compressive force 30 in the inner diameter direction, and as a result, this spiral circlip 10 boots 5
can be fixed to the socket 11 with a large amount of force.
