A rigorous equation for the one-particle distribution function is studied for a system of hard rods. When the fugacity z is less than or equal toe (the base of the natural logarithm) divided by the diameter 15 of the hard rods, it is proved that the only solution of the equation is spatially uniform. It is also proved that the equation has neither a solution corresponding to a perfect crystalline structure nor a solution bifurcating continuously from the uniform solution.
