Abstract
Abstract In the present packing hold structure, in a packing, there are provided projecting portions which respectively project toward the two mutually opposing inner surfaces 13 of a packing storage groove 13, and a dimension between the two projecting portions is set larger than the width dimension 13 of the packing storage groove 13. While the packing is stored within the packing storage groove, the projecting portions of the packing are respectively pressed against the two inner surfaces of the packing storage groove 12, thereby allowing the packing 12 to be held by itself within the packing storage groove.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A packing hold structure, comprising: an elastic packing within a packing storage groove formed in a seal end face, said elastic packing comprising: a pair of projecting portions extending in opposite directions and respectively having convexly curved side outer surfaces in an uncompressed state, said projecting portions respectively projecting toward two mutually opposing inner surfaces of said packing storage groove, wherein a dimension between said curved outer surfaces of said projecting portions is larger than a width dimension of said packing storage groove, and wherein when said packing is stored within said packing storage groove, said curved outer surfaces of said projecting portions are respectively pressed against inner surfaces of said packing storage groove allowing said packing to be held by itself within said packing storage groove.
Claim 2
Dependent Claim
127 words
A packing hold structure, comprising: an elastic packing within a packing storage groove formed in a seal end face, said elastic packing comprising: a pair of projecting portions extending in opposite directions and respectively having convexly curved side outer surfaces in an uncompressed state, said projecting portions respectively projecting toward two mutually opposing inner surfaces of said packing storage groove, wherein a dimension between said curved outer surfaces of said projecting portions is larger than a width dimension of said packing storage groove, and wherein when said packing is stored within said packing storage groove, said curved outer surfaces of said projecting portions are respectively pressed against inner surfaces of said packing storage groove allowing said packing to be held by itself within said packing storage groove.
Claim 3
Dependent Claim
99 words
A packing hold structure as set forth in the claim 1 , further comprising: absorbing recessed portions for absorbing reactive forces generated when said projecting portions are pressed against said inner surfaces of said packing storage groove and for restricting expansion of said packing in a direction where said packing is projected from said seal end face, wherein said absorbing recessed portions are formed on a bottom facing side of said packing which faces the bottom surface side of said packing storage groove and a seal surface side of said packing which is opposite to said bottom facing side.
Claim 4
Dependent Claim
35 words
A packing hold structure as set forth in claim 2 , wherein said packing comprises a plurality of said projecting portions which are projected toward one of said inner surfaces of said packing storage groove.
Claim 5
Dependent Claim
35 words
A packing hold structure as set forth in claim 1 , wherein said packing comprises a plurality of said projecting portions which are projected toward one of said inner surfaces of said packing storage groove.
Claim 6
Dependent Claim
95 words
A packing hold structure as set forth in the claim 1 , wherein said pair of projecting portions comprise first and second pairs of projecting portions, wherein a dimension between distal ends of each of said first and second pairs is larger than a width dimension of said packing storage groove, and wherein when said packing is stored within said packing storage groove, said first and second pairs of projecting portions are pressed against said inner surface of said packing storage groove allowing said packing to be held by itself within said packing storage groove.
Claim 7
Dependent Claim
119 words
A packing hold structure, comprising: an elastic packing within a packing storage groove formed in a seal end face, said elastic packing comprising: a main body; and first and second pairs of convexly curved projecting side portions respectively projecting from opposite sides of said main body toward inner surfaces of said packing storage groove, wherein a dimension between distal ends of said first and second pairs is larger than a width dimension of said packing storage groove, and wherein when said packing is stored within said packing storage groove, said pairs of projecting side portions are pressed against said inner surface of said packing storage groove allowing said packing to be held by itself within said packing storage groove.
Claim 8
Dependent Claim
119 words
A packing hold structure, comprising: an elastic packing within a packing storage groove formed in a seal end face, said elastic packing comprising: a main body; and first and second pairs of convexly curved projecting side portions respectively projecting from opposite sides of said main body toward inner surfaces of said packing storage groove, wherein a dimension between distal ends of said first and second pairs is larger than a width dimension of said packing storage groove, and wherein when said packing is stored within said packing storage groove, said pairs of projecting side portions are pressed against said inner surface of said packing storage groove allowing said packing to be held by itself within said packing storage groove.
