Block compactor

A block compactor, comprising:

• a base;
• a motor mounted on the base;
• an exciter that generates vibration by rotational drive force supplied from the motor;
• a plurality of rollers, at least the surface layers of which are made of an elastic material, and which are rotatably arranged on the underside of the base;
• and a parking brake mechanism that can lock the rotation of the rollers, wherein:
• the parking brake mechanism consists of a brake shaft, a brake pad, and a brake lever;
• the brake pad is fixed to the lower end portion of the brake shaft, and is configured to be rotatable together with the brake shaft at a position between two rollers adjacent in the front and rear among the plurality of rollers;
• and
• by rotating the brake lever, the brake shaft and the brake pad are rotated to switch between an unlocked state in which the brake pad does not contact with the outer circumferential surfaces of the two rollers, and these rollers are free to rotate, and a locked state in which the brake pad contacts with the outer circumferential surfaces of the two rollers, and these rollers are unable to rotate due to the frictional force.
