Machine having vibration source

摘要

A machine with vibration source includes a frame for carrying a vibration source such as a motor. A housing is attached to a bottom of the frame, in which a sphere made of a rigid material is housed rotation free in a manner that a portion of the sphere is projected from an opening at the bottom of the housing. The surface of a plate made of a rigid material contacts the portion of the sphere projecting from the housing and the plate is surrounded by a member of an elastic material. The elastic member has an upwardly extending portion which surrounds the housing, and therefore, the elastic member controls the relative position between the sphere and the plate, and resultingly, rolling of the machine can be suppressed. In addition, since the sphere can be rotated on the plate, horizontal vibration of the machine is absorbed to be suppressed. Furthermore, since the sphere is supported by the plate and the plate is supported by a floor via the elastic member, vertical vibration of the machine is also suppressed.
