Abstract
A power transmission mechanism is for transmitting power from a handle of a spinning reel to an oscillating mechanism, and includes a pinion gear, a dual-stepped gear, and a driven gear. The pinion gear rotates in cooperation with rotation of the handle. The dual-stepped gear has a larger-diameter gear that is a helical-tooth gear and meshes with the pinion gear, and a smaller-diameter gear that is arranged coaxially with the larger-diameter gear and is formed unitarily with the larger-diameter gear. The smaller-diameter gear is a straight-tooth gear or a helical gear whose orientation is substantially the same as an orientation of the larger gear. The driven gear meshes with the smaller-diameter gear to rotate the oscillating mechanism. In a power transmission device in a fishing reel, manufacturing cost is reduced while suppressing noise.
