Disclosed herein is a linear compressor. In the present invention, a
spring sheet is equipped in an exhale cover to prevent an edge and an
outer circumference of an exhale spring from touching with the exhale
cover. A surface of the spring sheet is treated with a metal of the high
hardness, thereby protecting against its abrasion and transformation,
caused by a repetitive load from the exhale spring. Furthermore, the
durability is improved by enduring the excessive or local load from the
exhale spring.
