A linear compressor comprising: a shell having a cylindrical shape that extends in an axial direction; a compressor body disposed within the shell; a first shell cover coupled to a rear end of the shell in the axial direction; a second shell cover coupled to a front end of the shell in the axial direction; a first support device (500, 600) coupled to a front portion of the compressor body in the axial direction to support the compressor body; and a second support device disposed between the compressor body and the first shell cover to support the compressor body in the axial direction, wherein the first support device (500, 600) is disposed between an inner circumferential surface of the shell and the compressor body to support the compressor body in a radial direction, wherein the compressor body comprises a discharge cover (591, 691) configured to define a compression space in which the refrigerant is compressed and a discharge space through which the refrigerant discharged from the compression space flows, characterized in that the discharge cover (591, 691) comprises: a flange part (591f, 691f) coupled to a front surface of a frame; and a chamber part (591e, 691e) extending forward from the flange part (591f, 691f) in the axial direction to define the discharge space, wherein the first support device (500, 600) has one end coupled to an outer surface of the chamber part (591e, 691e) and the other end coupled to the inner circumferential surface of the shell. a shell having a cylindrical shape that extends in an axial direction; a compressor body disposed within the shell; a first shell cover coupled to a rear end of the shell in the axial direction; a second shell cover coupled to a front end of the shell in the axial direction; a first support device (500, 600) coupled to a front portion of the compressor body in the axial direction to support the compressor body; and a second support device disposed between the compressor body and the first shell cover to support the compressor body in the axial direction, wherein the first support device (500, 600) is disposed between an inner circumferential surface of the shell and the compressor body to support the compressor body in a radial direction, wherein the compressor body comprises a discharge cover (591, 691) configured to define a compression space in which the refrigerant is compressed and a discharge space through which the refrigerant discharged from the compression space flows, characterized in that the discharge cover (591, 691) comprises: a flange part (591f, 691f) coupled to a front surface of a frame; and a chamber part (591e, 691e) extending forward from the flange part (591f, 691f) in the axial direction to define the discharge space, wherein the first support device (500, 600) has one end coupled to an outer surface of the chamber part (591e, 691e) and the other end coupled to the inner circumferential surface of the shell. a flange part (591f, 691f) coupled to a front surface of a frame; and a chamber part (591e, 691e) extending forward from the flange part (591f, 691f) in the axial direction to define the discharge space, wherein the first support device (500, 600) has one end coupled to an outer surface of the chamber part (591e, 691e) and the other end coupled to the inner circumferential surface of the shell.
