Elastic body and linear compressor including the same

An elastic body, comprising:

• a plurality of elastic plates that are disposed about an axis and surround the axis in a circumferential direction, the plurality of elastic plates facing one another in a radial direction and defining a slit radially between adjacent elastic plates among the plurality of elastic plates,
• wherein the plurality of elastic plates are spaced apart from one another,
• wherein each of the plurality of elastic plates comprises:
• an elastic portion that spirally extends about the axis and away from the axis in the radial direction,
• an outer portion disposed at an outside of the elastic portion in the radial direction, and
• an inner portion disposed at an inside of the elastic portion in the radial direction,
• wherein the outer portions of the plurality of elastic plates are disconnected from one another, and the inner portions of the plurality of elastic plates are disconnected from one another,
• wherein the outer portion of a first elastic plate among the plurality of elastic plates is disposed adjacent to the outer portion of a second elastic plate among the plurality of elastic plates,
• wherein the inner portion of the first elastic plate is disposed adjacent to the inner portion of the second elastic plate,
• wherein the plurality of elastic plates define an outer boundary portion between the outer portion of the first elastic plate and the outer portion of the second elastic plate, and
• wherein a width of the outer boundary portion is equal to a width of the slit.
