Abstract
A hollow inner cylinder is provided in a lead end portion of a casing, and a pen shaft is inserted into the inner cylinder. The inner cylinder is connected to the casing through a partition wall having communication holes formed herein. In an annular space defined between the inner cylinder and the casing and located below the partition wall is filled an impregnation receptacle holding a dry preventing agent for preventing a nib from getting dried. The liquid applicator thus constructed is capable of effectively suppressing the drying of the nib without affecting the performance of liquid to be applied.
