摘要： PROBLEM TO BE SOLVED: To simplify a structure and to secure sufficient strength. SOLUTION: This guide device is provided with a side surface rolling roller supporting member 7 formed into an L-like shape and for supporting a side surface rolling roller 3a so that it may be rolled, and a front surface rolling roller supporting member 4 for supporting a front surface rolling roller 2 arranged perpendicular to a rising part and a horizontal part 6b of an approximately L shape of the side surface rolling roller supporting member 1. An elevator is guided along a guide rail 1 without requiring a lever and a rod as machined parts and without a vibrationproof spring having much number of parts. Therefore, manufacturing cost can be reduced, and the device can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide a guide device for an elevator with a simple structure and satisfactory riding comfortableness at low cost by directly setting a roller support member for supporting a side rolling roller and a front rolling roller on a car frame, and constituting each roller by use of an elastic material. SOLUTION: A side rolling roller support member 6 is provided vertically to a roller support member 4 set horizontally on the part of a car frame, and side rolling rollers 3a, 3b are rotatably pivoted thereto. A front rolling roller 2 is rotatably pivoted to a front rolling roller support member 7 provided vertically to the roller support member 4 and at a right angle to the side rolling roller support member 6. The roller support member 4 is fixed to a car frame by a fixing bolt 22. The side rolling rollers 3a, 3b and the front rolling roller 2 are formed of elastic bodies having characteristics of absorbing and damping the vibration of a rising and falling body. According to this satisfactory riding comfortableness can be provided without using a mechanical machined part or vibration isolating spring.

摘要： PROBLEM TO BE SOLVED: To inexpensively reduce traveling vibration with a simple structure by setting a rotational frequency of a rolling roller at a rated speed of an elevator to an area higher than a natural oscillation frequency of a lifter composed of a spring constant of a car room and a car room support elastic body. SOLUTION: Since a rotational frequency (fg) of a roller at a rated speed of an elevator is set to an area higher than a natural frequency (fc) composed of a spring constant of a car room and a car room support elastic body, a spring constant of a roller support elastic body is set smaller than the spring constant of the car room support elastic body to form a small diameter roller. Therefore, excellent traveling performance can be obtained without resonating since the natural frequency (fc) and the rotational frequency (fg) separate to a high area of the natural frequency (fc). An ordinary guide roller is generally not less than a diameter 125 mm, but for example, since it is formed in a small diameter of ϕ60 mm, a manufacturing cost of a roller single body can be reduced, and since an acceleration sensor is not required, the number of part items is reduced, a manufacturing process can be reduced, and a cost can be reduced with a simple structure.
