Title
(EN) LINEAR GUIDE DEVICE
(FR) DISPOSITIF DE GUIDE LINÉAIRE
(JA) リニアガイド装置
Abstract
(EN) Disclosed is a linear guide device, wherein a sealing member (17) is formed by connecting the following in the cross-sectional direction: a lip (26), a sealing base unit (25), a first extender (27) that has a smaller thickness measurement than the sealing base unit, and a first locking unit (28) that has a larger thickness measurement than the first extender. Furthermore, a retention plate (16) is provided with a base unit storage recess (20) for storing the sealing base unit, and is also provided with a first engaging recess (21) for storing the first locking unit (28) on the inside of same, and for controlling the first engaging unit in a manner such that the sealing member does not slip out. The first engaging unit (28) has a narrow opening in both the thickness direction and the cross-sectional direction, and is stored in the first engaging recess.
(FR) L'invention concerne un dispositif de guide linéaire, dans lequel un élément d'étanchéité (17) est constitué en reliant les éléments suivants dans la direction transversale: une lèvre (26), une unité de base d'étanchéité (25), une première allonge (27) qui a une valeur d'épaisseur plus faible que celle de l'unité de base d'étanchéité et une première unité de blocage (28) qui a une valeur d'épaisseur plus forte que celle de la première allonge. On trouve en outre une plaque de retenue (16) ayant un évidement (20) de rangement de l'unité de base pour loger l'unité de base d'étanchéité et ayant également un premier évidement d'enclenchement (21) pour loger la première unité de blocage (28) à l'intérieur de celui-ci et pour contrôler la première unité d'enclenchement de manière à ce que l'élément d'étanchéité ne s'échappe pas. La première unité d'enclenchement (28) comporte une ouverture étroite tant dans la direction de l'épaisseur que dans la direction transversale et est logée dans le premier évidement d'enclenchement.
(JA)  シール部材(17)は、リップ(26)と、シール基部(25)と、シール基部より厚み寸法を小さくした第1延長部(27)と、第1延長部より厚み寸法を大きくした第1係止部(28)とが断面方向に連続して形成した部材である。保持板(16)は、シール基部を収容する基部収容凹部(20)と、第1係止部(28)を内部に収容し、シール部材が抜け出ないよう第1係合部を規制する第1係合凹部(21)とを備えている。第1係合部(28)は、厚み方向及び断面方向の両方に隙間を設けて第1係合凹部に収容されている。
