Latest Patents

One of Imanishi's latest patents is a "Starter with Driving Lever Having Lever Pin." This invention aims to reduce the entire length and radial dimension of a starter. The design includes a driving lever composed of a lever body and a lever pin, which serves as the pivot center of the driving lever body. The lever pin is strategically positioned close to the center case in the radial direction. Additionally, the distance between the supporting positions of both arm portions that support the lever pin is set large. To enhance the waterproof structure of the starter, a projection on a lever seal is inserted into a positioning hole of a lever holder in the lever assembly. The tip of this projection contacts the peripheral surface of the lever pin below its center.

Another significant patent is the "Starter with Pinion Regulating Claw and Spring." In this design, one end of a spring is connected to a pinion, while the other end connects to an annular plate. The regulation claw, which is part of a regulation member, moves the pinion toward a ring gear. This claw is separate from the spring, which flexes in the rotational direction of the output shaft to engage the pinion with the ring gear when contact is made. This design allows for easy specification adjustments of both the regulation claw and the spring, enhancing the durability of the spring.
