A line guide mechanism (8) for a spinning reel is provided with the stationary shaft cover (21) and the line roller (23) for guiding a fishing line (L) to a spool (4). The stationary shaft (20) is fixed at one end to a bail support member (7). The stationary shaft cover (21) is fixed to the other end of the stationary shaft (20) at an interval with the bail support member (7). The line roller (23) is rotatably supported to the stationary shaft (20) between the bail support member (7) and the stationary shaft cover (21) for guiding the fishing line to the spool when the fishing line is wound. A line guide surface (34d) is formed on a circumferential surface of the line roller (23) so that a diameter is increased on the side of the stationary cover (21). The fishing line is displaced on the side of the line guide surface (34d) while being guided by the line roller (23) when the fishing line is wound. Even if a line roller is biased toward a stationary cover, the line roller is not brought into contact with a stationary shaft cover.
