    Abstract: According to the embodiment, a sanitary washing device includes a casing, a nozzle, and a nozzle drive unit. The nozzle drive unit advances and retracts the nozzle between a storage position and an advanced position. The nozzle drive unit includes a supporter, a gear, and a cable rack. The supporter includes a rail allowing the nozzle to slide. The gear applies a drive force to advance and retract the nozzle. The cable rack is connected with the nozzle and meshes with the gear. The cable rack includes a nozzle connection part connected with the nozzle. The gear and the cable rack mesh at a meshing part. The meshing part is positioned at a same position in a longitudinal direction as the nozzle connection part or further frontward than the nozzle connection part when the nozzle is at the storage position.

    Abstract: A sanitary washing device includes a casing and a nozzle unit. The nozzle unit advances and retreats between the casing and a toilet. The nozzle unit is curved to be upwardly convex and advances and retreats along an arc-like trajectory. The nozzle unit includes a first flow channel through which water flows and a second flow channel connected to the first flow channel. A water flow direction of the second flow channel in a longitudinal direction of the nozzle unit is different from a water flow direction of the first flow channel in the longitudinal direction.

    Abstract: A sanitary washing device includes a nozzle unit configured to advance and retreat between a toilet bowl and a casing, and a support portion configured to slidably support the nozzle unit. The nozzle unit is curved convexly upward and includes a nozzle cover configured to advance and retreat along a track having an arc shape. The support portion includes a groove portion extending in an advance/retreat direction of the nozzle unit, and a rail portion extending in the advance/retreat direction of the nozzle unit at a position different from a position of the groove portion. The nozzle unit includes a protruding portion held sandwiched by the groove portion in an up-down direction and configured to come into line contact with the groove portion, and a recessed portion held at either side of the rail portion in the up-down direction.

    Abstract: The present invention is a spout apparatus including: a spout forming member configured to form a spout; a flow-guiding member provided inside the spout forming member, configured to guide water on an upstream side of the spout; an exposed flow-guiding member provided inside the spout forming member and on a spout side of the flow-guiding member, and exposed on a spout side of the exposed flow-guiding member; and a water channel configured to supply the water to an upstream side of the flow-guiding member. The exposed flow-guiding member and/or the spout forming member are configured to spout water from an outer periphery as an annular stream, among the water spouted from the spout. According to the above spout apparatus, the flow-guiding member can be effectively protected, and high guiding characteristics can be achieved in particular at an outer periphery of the spout.
