Abstract: A waterproof case for automobile components includes: a case body part that includes a storage space for housing an object and an opening connecting to the storage space; and a lid part that is configured to be attached to the case body part to close the opening. A seal material (made of an adhesive silicone gel is interposed between the case body part and the lid part. An acceptance part is provided in at least one of the case body part and the lid part. An engagement convex part is configured to be locked in the acceptance part at a position corresponding to the acceptance part in the case body part and the lid part.

Abstract: An air conditioning apparatus has a case, a heat exchanger rotatable about a rotation axis in the case, and a pipe unit in communication with the heat exchanger. The pipe unit has a first section fixed to the case and a second section coaxially coupled to the first section. The second section is coupled to the heat exchanger and rotatable with the heat exchanger. The first section has a first annular portion, a second annular portion, a cylindrical portion, and a support member. The second section has a flange portion disposed between the first annular portion and the support member. An O-ring is disposed in a groove provided by the first annular portion and the cylindrical portion, and is in contact with a surface of the first annular portion and the flange portion in a direction parallel to the rotation axis.

Abstract: A sealing structure of a rotation unit has a first member defining a first axis, a second member defining a second axis and an O-ring disposed between them. The first member and the second member are substantially coaxial, and at least one of the first member and the second member rotates about its respective axis. The first member and the second member have a first surface and a second surface extending in a direction perpendicular to the first and second axes, respectively. The O-ring is disposed between and in contact with the first surface and the second surface. The sealing structure further has a movable range regulating part that maintains the first and second axes in substantially alignment by reducing relative displacement of at least one of the first and second members away from alignment.
