Portable Toilet

Abstract

A portable toilet used in outdoor activities including driving, camping, and fishing, and in time of disasters such as earthquake is provided, which portable toilet can be provided inexpensively as the structure of the toilet seat portion to be installed on a pail can is very small and thus can be mass produced at low material cost.
