Claims

[Scope of utility model registration request]

An annular engaging part, a base part coaxially and rotatably fitted to the engaging part, and an elastic member interposed between the engaging part and the base, wherein the engaging part and the base part are connected to each other. When an impact force is applied to either of the
In a gear having a buffering function that reduces the impact force by elastic deformation of the elastic member due to relative rotation between the two, an annular groove is formed on the outer periphery of one end in the length direction of the base. and on the inner circumferential side of the engagement part, engagement steps opening toward the base and extending along the radial direction are formed on both sides sandwiching the base, and a bar-shaped engagement step is formed on both engagement steps. By engaging each end of the formed spring and deflecting the middle part of the spring to engage the annular groove, the middle part of the spring is connected to the base and both ends are connected to the engagement part. A gear with a buffer function characterized by being pressed into contact with the
