A coating apparatus for coating an object with a coating material in a coating direction includes a holder adapted to be mounted on a controllable support member, a shaft slidably supported in the holder, and a head member mounted on the shaft for angular movement in a direction transverse to the coating direction, the head member having a sliding surface for slidable contact with the object and a coating material outlet positioned forwardly of the sliding surface in the coating direction. In another embodiment, the head member has sliding legs for sliding contact with the object at front and rear positions in the coating direction, at least one of the sliding legs having a recess defined therein to provide a gap between the sliding leg and the object, the gap having a prescribed width in a direction transverse to the coating direction. The head has a coating material outlet defined between the sliding legs and a concave coating material reservoir defined between the sliding legs for temporarily storing the coating material supplied form the coating material outlet and for supplying the stored coating material into the recess.
