摘要： A bubble separator used in a fluid circuit for an automobile and that separates bubbles in a refrigerant may include a swirl flow formation part extending in a substantially horizontal direction, and including an internal space having a columnar shape. The bubble separator may also include a flow inlet disposed at one end of the swirl flow formation part, and being open so as to cause the refrigerant to flow in the flow inlet in a tangential direction of an inner peripheral surface of the swirl flow formation part and so as to form a swirl flow on the inner peripheral surface. The bubble separator may also include a flow outlet disposed at another end of the swirl flow formation part, and being open so as to cause the refrigerant to flow out of the flow outlet in a tangential direction from the inner peripheral surface. The bubble separator may further include a gas discharge port to discharge gas separated from the refrigerant in the swirl flow formation part outside of the swirl flow formation part, and at least one liquid drop nozzle provided on a wall surface of the swirl flow formation part.

摘要： [Problem to be Solved] To improve operability in detaching a sealing member.
[Solution] A sealing structure 10 according to the present invention includes a main body 30a, a female thread part 20h fixed to the main body 30a, the female thread part 20h being screwed into a discharge hole 20c of a drain plug fastening part 20 by the main body 30a being rotated in a normal rotation direction, and an elastically deformable arm part 30c, one end of which is joined to the main body 30a. A concave part 20e is formed in the drain plug fastening part 20 and a claw part 30g is formed in the arm part 30c. When the main body 30a is rotated in the normal rotation direction, the arm part 30c is elastically deformed while a part of the arm part 30c slides on a top surface 20d of the drain plug fastening part 20 until the main body 30a is rotated to a predetermined rotational position and, when the main body 30a is rotated to the predetermined rotational position, the claw part 30g fits in the concave part 20e and the elastic deformation of the arm part 30c is released, whereby the rotation of the main body 30a from the predetermined rotational position is prevented. When the main body 30a is rotated in a reverse rotation direction from the predetermined rotational position, the claw part 30g slides on and climbs over a first wall part 20f of the concave part 20e while the arm part 30c is elastically deformed, whereby the prevention of the rotation of the main body 30a from the predetermined rotational position is released. The claw part 30g or the concave part 20e is formed such that, when the main body 30a is rotated in the reverse rotation direction and the claw part 30g is sliding on the first wall part 20f, an angle A formed by a direction of force applied to the arm part 30c from the drain plug fastening part 20 and a straight line connecting a contact part of the claw part 30g and the first wall part 20f and a rotation center of the main body 30a is smaller than 90 degrees when viewed in a rotation center direction of the main body 30a.
