To reduce a sense of discomfort applied to a user when automatically adjusting a nozzle position in a portable toilet device with a flushing seat that has a mechanism for detecting a load distribution of the user and automatically adjusting the nozzle position on the basis of the load distribution.

A portable toilet device with a flushing seat 1 has an adjustment mode automatically adjusting the position of a nozzle 33 on the basis of an output of a load sensor. When a proximal sensor 34 determines that an inclination of a user's upper body reaches a predetermined angle, the automatic adjustment mode does not operate. This configuration can reduce jetting of wash water to an inappropriate position that occurs due to an influence of an extreme forward inclination or the like of the upper body on the load distribution so as to reduce the sense of discomfort of the user.
