Claims

[Scope of utility model registration request]

In a passive shedding device that uses spring action to move a heald frame up and down, a spring hanger that protrudes from a spring that hangs a spring that biases a jack lever in a predetermined direction, which is swingably supported on a support shaft. The cross-sectional shape of the pin, which is engaged with the latching hole of the latching portion provided at the end of the spring, has a shape whose distance from the center of gravity is not constant;
A spring retaining structure in a passive shedding device for a loom, wherein the shape of the retaining hole is such that it has a surface that abuts at least both upper side surfaces of the pin.
