A flexible tube for an endoscope has a flexible tube substrate that is flexible and tubular and a resin layer (A) covering the flexible tube substrate. The resin layer (A) includes a thermoplastic resin (a) including at least one of a polyatnide resin, a polyurethane resin, a polyester resin, a polystyrene resin, or an acrylic resin and having a tensile strength at 10% elongation of 10 Pa or more and a hindered amine compound (b) having a molecular weight of 500 or more. Also provided are an endoscopic medical device including the flexible tube for an endoscope and a resin composition suitable for forming the resin layer of the flexible tube for an endoscope.

In a sliding shaft, an outer circumferential surface of a male shaft is coated with a resin coating layer formed by a fluidized bed powder coating method using a powder coating material containing a base resin and at least either a carbon black or a metal oxide as an antistatic agent. A steering device includes this sliding shaft as an intermediate shaft transmitting steering force.
