Abstract:
A protective cap for an inkjet recording apparatus includes a recording head having an ejection surface in which open ends of nozzles are arranged in a row. The cap includes a mainbody and an elastic lip portion. The mainbody is formed of a first material mainly composed of thermoplastic elastomer and containing butyl rubber. The first material has a hardness of a first degree. The mainbody includes a base portion, and a protruding portion formed integrally with the base portion to protrude from the base portion. The lip portion is formed of a second material mainly composed of thermoplastic elastomer and containing butyl rubber. The second material has a hardness of a second degree lower than the first degree. The lip portion is disposed on at least the protruding portion to cover at least an end portion of the protruding portion.
