Elevator brake

An elevator brake, comprising:

• a hoisting machine provided with at least a frame part and a traction sheave;
• a brake drum arranged to be rotatable with the traction sheave and provided with a braking surface;
• and
• a brake configured to provide a braking effect on the rotary motion of the traction sheave, said brake comprising at least one brake block provided with a braking surface, said brake block being arranged to act on the braking surface of the brake drum with a force directed substantially towards the braking surface,
• wherein the brake is provided with a first eccentric adjusting element and a second eccentric adjusting element, arranged on a first end and a second end of the brake, respectively, to adjust size of an air gap between the braking surface of the brake block and the braking surface of the brake drum, and
• wherein the second eccentric adjusting element at the second end of the brake is placed in a substantially loose through hole whose diameter is substantially larger than the diameter of the second eccentric adjusting element, and wherein a portion of the periphery of the substantially loose through hole which lies closer to the brake drum directly contacts and bears against the second eccentric adjusting element to form a stop face for the second eccentric adjusting element.
