<p>PROBLEM TO BE SOLVED: To enable application of a minimum amount of lubricant to a guide shoe by a simple structure while preventing generation of abnormal sound and abnormal vibration and fouling by splashed lubricant.SOLUTION: An oiling device for oiling the guide shoe 3 that slides on a guide rail 1 vertically erected in a place where a car and a balance weight 2 are disposed so as to be movable in a vertical direction, comprises: a contact surface pressure detection device 7 (contact surface pressure detection means) for detecting the contact surface pressure between the guide rail 1 and the guide shoe 3; and an oil application device 4, piping 5, an oil leading path 6, first to third openings 6a, 6b, 6c, and an oil application control device 8 which feed a minimum amount of lubricant to a contact surface to the guide rail 1 when the contact surface pressure detection device 7 detects that the contact surface pressure is higher than a preset threshold.</p> |
