Wellenkonstruktion eines Beschichtungwerkzeugs

摘要

A shafting structure for a coating tool adapted to transfer to a target object a paste or a correcting paint which is adhered to a transfer tape. The coating tool comprises a main body housing therein a supply reel (10) and a supply reel gear which are supported by the same shaft and a take-up reel and a take-up reel gear. The shafting structure is such that an annular rib (17) is formed on a cylindrical portion of the supply reel gear and a number of elastic frictional strips (15) for holding and engaging the supply reel gear is formed on the inner wall surface of an engagement hole (13) of the supply reel whereby holding and engagement of the supply reel gear by the elastic frictional strips of the supply reel is secured thereby allowing delivery and taking-up of the transfer tape in a smooth amnner whiel by preventing a thermal deformation of the elastic frictional strips.
