END CAP AND LINEAR MOTION GUIDE BEARING DEVICE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To make specifications of an end cap changeable and to improve operability of a linear motion guide bearing device. SOLUTION: The linear motion guide bearing device 1 comprises an end cap 10 formed with a direction changing path 20 serving for communication between a load rolling path 18 formed between a rail side rolling element rolling groove 6 and a slider side rolling element rolling groove 14, and a rolling element return path 16, and has a plurality of rolling elements 24 charged in a rolling element rolling path 22. The direction changing path 20 comprises a load rolling path side curved part 34 of circular arc shape communicating with the load rolling path 18; a rolling element return path side curved part 36 of circular arc shape communicating with the rolling element return path 16; and a straight line part 38 extending in a straight line with both ends communicating with the load rolling path side curved part 34 and the rolling element return path side curved part 36. The straight line part 38 is formed to establish a conditional expression A
