Yoshitaka Katashima is a notable inventor based in Saitama-ken, Japan. He has made significant contributions to the field of electric steering actuators, holding a total of 2 patents. His work focuses on enhancing the efficiency and manufacturability of steering systems in vehicles.

Latest Patents

One of his latest patents involves an electric steering actuator that features an electric motor with a hollow output shaft. This design allows a steering shaft to pass through the hollow center of the output shaft. A ball-screw mechanism is integrated between the output shaft and the steering shaft, converting the rotary movement of the output shaft into a longitudinal movement of the steering shaft. This innovative mechanism reduces the overall axial dimension of the actuator and simplifies the assembly process, making it easier to manufacture and service.

Another patent by Katashima also pertains to an electric steering actuator. In this design, a rotation preventing mechanism is included to stop the steering shaft from rotating around its axial line. This mechanism utilizes a guide pin and a fork member, which simplifies the manufacturing process and reduces costs. The use of a plastic slider between the pin and the fork member further ensures smooth operation while minimizing metallic noises.
