<p>PROBLEM TO BE SOLVED: To provide a suspension mechanism capable of inhibiting a sheave from rotating.SOLUTION: A suspension mechanism 100 includes: a suspending tool 3; a support bracket 10 having a support part 11 supporting the suspending tool 3, an extension part 12 extending upward from an upper surface 11a of the support part 11, and a large diameter part 13 provided at an outer periphery of the extension part 12 and having a diameter larger than the extension part 12; a fixed bracket 20 which is fixed to the frame 1 and has a housing part 24 for housing the large diameter part 13; rotation support members 31, 33 which may slide in a vertical direction in the housing part 24 and support the large diameter part 13 in an axial direction so that the support bracket 10 may rotate around an axis center of the extension part 12; a biasing member 34 which biases the rotation support members 31, 33 upward; and a brake part 35 which puts a brake on relative rotation between the support bracket 10 and the fixed bracket 20.</p> |
