Abstract
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.
