Abstract: Provided is an evaporated fuel treatment device including a mounting part 90 provided in an intake pipe, and a purge pump 5 including a discharge part 71, a first introduction tube 61, and a second introduction tube 66. A pump body 6 of the purge pump 5 includes a pump tube 7 formed with a pump flow path 70 that extends along an axis O and that guides, to the discharge part 71, fluid to be introduced from the introduction tube 61. A reduced part 73 with a diameter decreasing toward downstream is formed in the flow path 70 on a side downstream of the introduction tube 61, and a connection flow path 78 that connects the introduction tube 66 and the flow path 70 is formed, and in a state where the pump body 6 is removed from the mounting part 90, the flow path 78 communicates with outside.

Abstract: It is an object of the present invention to provide a transgenic cell and gene recombinant animal having a mutant SDHC gene, which enables the examination of the action of reactive oxygen species (ROS) derived from mitochondria in mammals. The present invention provides a transgenic animal cell and a gene recombinant non-human mammal, which are characterized in that a mutant SDHC gene derived from mammals is introduced, and that reactive oxygen species (ROS) are excessively produced.
