Title: Seiichi Nieda: Innovator in Engine Starting Technology

Introduction

Seiichi Nieda is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of engine starting technology, holding a total of 10 patents. His innovative designs have improved the efficiency and functionality of recoil starters.

Latest Patents

One of his latest patents is a recoil starter designed for starting an engine. This embodiment includes a starter case with a storage portion, a rope reel that is rotatably accommodated in the storage portion, and a recoil rope wound on the rope reel. A recoil spring is interposed between the rope reel and the starter case within the storage portion. Additionally, it features a cam portion that is rotatable concentrically with the rope reel and is engageable with the engine. A dust cover is provided on the opening of the storage portion to cover the rope reel. The rope reel has concentric circular uneven portions formed on its surface facing the engine, which fit with the circular uneven portions of the dust cover to create a nest structure.

Another embodiment of his recoil starter includes a starter case, a rotational torque applying unit, a torque-accumulation spring, a rotating member, a driving pulley, and a rotation regulating mechanism. This mechanism consists of a regulating ratchet positioned on the driving pulley or the rotating member, along with a pressing unit that is urged by a given resilient pressing force to engage with the regulating ratchet. When the rotational torque accumulated in the torque-accumulation spring exceeds the pressing force, the driving pulley or rotating member disengages the pressing unit from the regulating ratchet, thereby releasing the rotational torque.
