A cable type steering system includes an operation cable having an outer tube and inner cable slidably received in the outer tube. A drive pulley coupled to a steering wheel for rotation and a driven pulley coupled to a steering gear box for steering wheels for rotation are connected to end portions of the inner cable. A steering torque inputted to the steering wheel is transmitted to the steering gear box via the inner cable of the operation cable. At least one of a first portion of the system extending from the drive pulley to a first position of the outer tube and a second portion of the system extending from the driven pulley to a second position of the outer tube is accommodated within a waterproof space formed by a cover, such as a rubber cover or a cover molded of synthetic resin.
