Claims

[Scope of utility model registration request]

A gap removing device for removing a gap between meshing parts between gears in a gear mechanism, wherein the gear is formed by a pair of gear structures superimposed coaxially and relatively rotatably; , a resilient member is provided between both gear structures to urge them in opposite directions in the circumferential direction to displace their respective teeth in the circumferential direction, A guide plate is provided so as to cover the side portion, and a guide groove is formed on at least one of the facing surfaces of the guide plate and the other gear component along the radial direction of the gear and that becomes gradually shallower toward the outside in the radial direction. A gap removing device for a gear mechanism, characterized in that a rolling element is disposed in the guide groove and is brought into contact with opposing surfaces of the guide plate and the other gear component.
