Document Type and Number:
WIPO Patent Application WO/2012/098961
Kind Code:
A1
Abstract:
[Problem] To provide a steering wheel having an in-mold film in which very small, bubble-shaped spaces do not form in the cross section of the in-mold film, and in which improved mechanical properties and durability can be obtained. [Solution] A protective film that forms the outermost layer of the steering wheel is an in-mold film having a monolayer structure formed by in-mold molding. The in-mold film contains particle clusters formed by laying out, accumulating, and cross-linking polymer particles. The film has very small, discontinuous, hairline spaces formed by a portion of the surface of the polymer particles not bonding together between these particle clusters.
