Abstract: A reciprocating type compressor may include a crank shaft that is coupled to a rotor of a motor to receive a rotational force and a connecting rod that is coupled to a pin of the crank shaft and converts a rotational force of the crank shaft into a linear motion of a piston. The connecting rod may include a first end having a tubular body that includes a pin insertion hole into which the pin of the crank shaft is inserted and a socket that projects from the tubular body, a second end coupled with the piston, and a main body that extends between the first end and the second end and having a ball that is received inside of the socket.
