  In this paper we discuss the structure of weighted weak Lebesgue spaces and
weighted weak Orlicz spaces on $\mathbb{R}^n$. First, we present sufficient and
necessary conditions for inclusion relation between weighted weak Lebesgue
spaces. Next, we also obtain similar results on weighted weak Orlicz spaces.
One of the keys to prove our results is to use the norm of the characteristic
functions of the balls in $\mathbb{R}^n$.
