Abstract: Provided is a portable bidet capable of maintaining the quality of cleaning water. A portable bidet is configured to include a tank portion formed to be compression-deformable and restorable to its original shape, a nozzle that is connected to the tank portion and can discharge a fluid, and a sealing portion that is provided continuously to the nozzle. The tank portion and the nozzle are connected via a cylindrical portion having a cylindrical shape. In a sealed state where the fluid is sealed by the sealing portion, the fluid is fully filled in a storing chamber in a state where the tank portion is compressed, and in an opened state where sealing by the sealing portion is released, the tank portion is restored to its original shape, and a volume of the storing chamber is expanded as compared with a volume of the storing chamber in the sealed state.

Abstract: A boot for a universal shaft coupling, by which an improvement of an assembling workability can be expected, and an improvement of a sealing performance can be expected. The boot for the universal shaft coupling is formed by a rubber elastic body, and separated portions (22) are formed linearly along a generatrix. A fastener pair (26) is arranged in both sides of the separated portions (22) so as to form a seal portion. The fastener pair (26) is constituted by an occluding portion (32) formed in one end edge of the separated portion (22) and provided with a bulge locking portion (32a) in a leading end, and an occluded portion (34) formed in another end edge of the separated portion (22) and provided with an occluding groove (33) occluding with the bulge locking portion (32a).
