A sliding window structure has a window frame comprising an upper frame member, a lower frame member and bilateral side vertical frame members which are assembled in substantially rectangular shape, and an indoor side sash and an outdoor side sash fitted to the window frame. The lower frame member comprises an indoor side portion to which the indoor side sash is mounted and the outdoor side portion to which the outdoor side sash is mounted and has a step-like configuration in which the indoor side portion has a height higher than a height of the outdoor side portion. An attachment is mounted to the outdoor side portion of the lower frame member so as to cover the outdoor side portion. An upper end of the attachment is substantially at the same height level as an upper end of the indoor side portion of the lower frame member.
