Latest Patents

Fujii's latest patents include advanced designs for damper devices. One of his inventions features a damper device that consists of a first rotating body, a second rotating body, a coil spring, and a spring seat. The coil spring is strategically placed in a circumferential direction between the two rotating bodies. The resin spring seat is designed with a seat portion, an overhang portion, and a pair of clamping protrusions. The overhang portion extends from the outer diameter end of the seat portion, covering the coil spring. The clamping protrusions are designed to sandwich an attaching portion of one of the rotating bodies, allowing for relative movement in the radial direction. Additionally, the clamping protrusions are engineered with varying rigidity, featuring a low-rigidity portion on the outer diameter side and a high-rigidity portion on the inner diameter side of the spring central axis.

Another patent by Fujii also focuses on a damper device, which includes a first rotating body, a second rotating body, a coil spring, and a spring seat. In this design, the resin spring seat incorporates a metallic core member. The metallic core member has a core seat part that is exposed to allow for direct contact with the coil springs. This innovative design enhances the performance and durability of the damper device.
