Abstract: A compressor having a starting load reducing apparatus comprises a main compressor body for compressing gas obtained under suction from an intake chamber through an intake valve within a compression chamber, and ejecting the compressed gas through an outlet opening, a motor for driving the main compressor body, a switch for starting the motor by closing, a solenoid mechanism operated by the closing of the switch, for forcibly communicating the compression chamber with the intake chamber, to put the main compressor body into a non-compressing operational state, and a positive thermally sensitive resistor element connected at a stage before a coil of the solenoid mechanism. The solenoid mechanism operates after the switch is closed until the time when the resistance of the positive thermally sensitive resistor element reaches a predetermined resistance.
