The ornamental design for the clutch spring, as shown and described.
|
FIG. 1 is a perspective view of the clutch spring;
FIG. 2 is a front view of the clutch spring;
FIG. 3 is a back view of the clutch spring;
FIG. 4 is a side view of the clutch spring; and,
FIG. 5 is a cross-sectional view of the clutch spring.
Since the clutch spring is circular in shape with a concave center portion, all side or edge views are the same.
The cross-sectional view in FIG. 5 is taken along the major top-to-bottom diameter of the clutch spring as shown in FIG. 2.
