PURPOSE: To enable mounting on various sizes of buckets for plasterer and also enable holding of trowels for plasterer stable at any height.

CONSTITUTION: A trowel holder for plasterer is installed along the peripheral surface of a bucket for plasterer. In the holder, two or more of slit forming columns 2 are installed projectedly on a flexible bar body 1 at a specified distance and vertically relative to the bar body 1. The material of the bar body 1 is not particularly restricted, but plastic and synthetic rubber are most suitable. Therefore, by simply bending the bar body by hand, it can be mounted on various sizes of buckets for plasterer and also, by varying the installation positions appropriately, trowels for plasterer can be held stably at any height.
