Abstract: A hydraulic machine according to embodiments described herein includes a channel defining member, a plurality of guide vanes, and a runner. The channel defining member defines a channel. Each of the guide vanes can turn about a turning axis. The runner is provided on an inner peripheral side of the guide vanes. The guide vane has a pair of edges facing the channel defining member. A disc member is provided to at least one of the edges of the guide vane. The disc member is buried in the channel defining member and includes a central axis which is the turning axis. The disc member overlaps with at least one of an upstream end of a downstream end of the guide vane when viewed from a direction along the turning axis.
