A scroll fluid machine includes a fixed scroll having a scroll portion and an orbiting scroll having a scroll portion provided so as to face the fixed scroll, wherein a convex portion is provided on at least one side surface of an outer line of one scroll portion and an inner line of the other scroll portion, in a portion where a deformation amount of the inner line of the other scroll portion facing the one scroll portion is larger than a deformation amount of the outer line of the one scroll portion on a tooth root side, and a concave portion is provided on at least one side surface of the outer line of the one scroll portion and the inner line of the other scroll portion, in a portion where the deformation amount of the inner line of the other scroll portion on the tooth root side is smaller than the deformation amount of the outer line of the one scroll portion on the tooth root side, and the concave portion or the convex portion is located at a position other than a lowermost end and an uppermost end in a height direction of the scroll portion.)

1. A scroll fluid machine, comprising:

a fixed scroll having a scroll portion in a spiral shape; and

an orbiting scroll disposed opposite to the fixed scroll and having a spiral-shaped scroll portion,

a portion where an inner line of one of the fixed scroll and the orbiting scroll has a larger deformation amount than an outer line of one of the fixed scroll and the orbiting scroll on a tooth crest side than an inner line of the other of the fixed scroll and the orbiting scroll on a tooth crest side has a convex portion on a side surface of at least one of the outer line of the one of the fixed scroll and the orbiting scroll on the inner line of the other of the fixed scroll and the orbiting scroll,

a portion where the amount of deformation of the inner wire on the tooth crest side of the other coil portion is smaller than the amount of deformation of the outer wire on the tooth root side of the one coil portion has a concave portion on at least one side surface of the outer wire of the one coil portion and the inner wire of the other coil portion,

the concave portion or the convex portion is located at a position other than a lowermost end and an uppermost end in a height direction of the scroll portion.

2. A scroll fluid machine, comprising:

a fixed scroll having a scroll portion in a spiral shape; and

an orbiting scroll disposed opposite to the fixed scroll and having a spiral-shaped scroll portion,

a recess portion is provided in at least one of the inner line of the coil portion of the one and the coil portion of the other, in a portion where an outer line of a tooth top side of the coil portion of the other opposite to the coil portion of the one is deformed by a larger amount than an amount of deformation of the inner line of a tooth bottom side of the coil portion of the one of the fixed scroll and the orbiting scroll,

a convex portion is provided on a side surface of at least one of the inner line of the one of the coil portions and the outer line of the other of the coil portions, in a portion where a deformation amount of the tooth top side outer line of the other of the coil portions is smaller than a deformation amount of the tooth bottom side inner line of the one of the coil portions,

the concave portion or the convex portion is located at a position other than a lowermost end and an uppermost end in a height direction of the scroll portion.
