摘要：PURPOSE: To provide a packing which can be prevented from a fall and a fall-down from a groove formed at either of a housing main body and a cover plate in a housing having tightness in an apparatus such as a pump and engine, is excellent in durability and reliability, can be reduced in an expen of a metal mold and an expen of a product, and can homogeneously stabilize al performance.CONSTITUTION: A packing A formed into an annular shape in a longitudinal direction and having a uniform cross ction in the longitudinal direction is, when viewed in cross ction, compod of an apex face arc-shaped part 1, a bottom-face side arc-shaped part 2 and two-side side-face arc-shaped parts 3, 3. Both ends of the apex face arc-shaped part 1 and the two-side side-face arc-shaped parts 3, 3 are connected to each other by upper connecting faces 4, 4, both ends of the bottom-face side arc-shaped part 2 and the two-side side-face arc-shaped parts 3, 3 are connected to each other by lower connecting faces 5, 5, respectively, and a clearance between the two-side side-face arc-shaped parts 3, 3 has a maximum width. An angle θ formed of a vertical line h of a most bottom point P2 in a height direction of the bottom-face side arc-shaped part 2 with respect to a line component of an apex P1 in a height direction of the apex face arc-shaped part 1 and the most bottom point P2 is formed at the outside or the inside of an annular shape so as to
be inclined.SELECTED DRAWING: Figure 1申请人：株式会社山田製作所
