- ケーシングの両端に設けたエンドキャップを設けたスライダと、これらエンドキャップ間に掛け渡した下面カバーとを備えた直動転がり案内ユニットにおいて、上記エンドキャップには、上記下面カバーが接する斜面を形成し、しかも、この斜面の両端部分において斜面と隣接する軌道面付きレール側に、上記斜面に対して段差を有する圧接面を形成し、かつ、上記斜面であって圧接面に隣接する位置に、下面カバーの長手方向に一定の長さを保持するとともに圧接面側に開放された鉤部材を設け、しかも、この鉤部材の開放側とは反対側面に鉤部材より低くした掛止用突部を形成し、かつ、一方、上記下面カバーには、その両端部分に掛止孔を形成するとともに、この掛止孔はそれを鉤部材に掛け止めたとき、上記掛止用突部が圧入される大きさを保つ一方、この下面カバーであって、上記圧接面に対向する側面に弾性突部を形成し、この弾性突部の弾性力で、掛止孔周囲が鉤部材に圧接する構成にした直動転がり案内ユニット。
- 上記下面カバーは、上記弾性突部とは反対側で、かつ、下面カバーの長手方向全長にわたって第1リップ部を形成し、下面カバーの掛止孔を鉤部材に掛け止めたとき、上記第1リップ部がケーシングおよびエンドキャップに圧接する構成にした請求項1記載の直動転がり案内ユニット。
- 上記下面カバーは、上記掛止孔と第1リップ部との間で、かつ、長手方向の長さを、エンドキャップにおける斜面の長手方向の長さとほぼ等しくした第2リップ部を設け、下面カバーの掛止孔を鉤部材に掛け止めたとき、上記第2リップ部がエンドキャップの斜面に圧接する構成にした請求項2記載の直動転がり案内ユニット。
