Claims (1)

[Claims for Utility Model Registration] 1. On one side of the movable body 2 that reciprocates along the linear guide rail 1, an inner side is formed with a substantially C-shaped cross section, and the two end portions 16, 16 face each other. One end of a protective cover body 9 formed to have an elastic force to close the legs in the direction is connected, and both tip ends 16, 16 of the protective cover body 9 are elastically attached to both sides of the linear guide rail 1. The protective cover body 9 is provided to cover a portion of the linear guide rail 1 that comes into contact with the moving body 2 and is located on one side of the moving body 2, and the protective cover body 9 is provided to cover the part of the linear guide rail 1 that is located on one side of the moving body 2. In order to maintain the covered state of the portion of the linear guide rail 1 located on one side of the moving body 2 when moving along the line, at least the entire length of the linear guide rail 1 is set to be longer than the reciprocating movement dimension of the moving body 2, and the protection On the other end side of the cover body 9, a shape-retaining means 14 is provided to maintain both tip ends 16, 16 of the portion projecting outward from the end of the linear guide rail 1 in an open state. A protective structure for a linear guide rail characterized by: 2. In the protection structure for the linear guide rail as described in claim 1 of the utility model registration, at one end of the linear guide rail 1, there is a protective structure formed between the protective cover body 9 and the one end of the linear guide rail 1. A protective structure for a linear guide rail, characterized in that a sealing body 11 is provided which slidably abuts on the inner surface of a protective cover body 9 to close a gap 17 between the two sides. 3 A cross section of approximately C
Both ends of the protective cover body 4, which is formed in a letter shape and is formed to have a resilient force to close in the inward direction where both ends 15, 15 face each other, are connected,
Moreover, the protective cover body 4 has both ends 15, 15.
A protection structure for a linear guide rail, characterized in that abutting against both sides of the linear guide rail 1 with elastic force is provided to cover a portion of the linear guide rail 1 located between the movable bodies 2 and 2a. . 4 In the protective structure for a linear guide rail as described in claim 3 of the utility model registration, an oil coating material 8 impregnated with oil is provided on the inner surface of the protective cover body 4 so as to be able to come into sliding contact with the linear guide rail 1. A protective structure for a linear guide rail characterized by being provided as much as possible.
