Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 RIMポリウレタン二色成形品において、同 成形品に形成された嵌合凹部と他物体に設けられた嵌合 凸部との嵌合後の抜け荷重を高める。 【解決手段】 ステアリングホイール70のポリウレタ ン被覆74は、減圧下のキャビティに表面部用ポリウレ タン材料U1 を注入することにより形成された表面部7 5と、減圧下のキャビティに内部用ポリウレタン材料U 2 を注入することにより形成された内部76とからなる RIMポリウレタン二色成形品である。スポーク部72 のポリウレタン被覆74の凹所77には、パッド部80 の嵌合凸部81を嵌入させるための嵌合凹部78が形成 され、その内周には掛止凹部82に掛止する掛止凸部7 9が形成されている。嵌合凹部78の周囲部位は、表面 部用ポリウレタン材料U1 によって厚肉に形成されてい る。 (57) Abstract: In a two-color molded article of RIM polyurethane, a detachment load after fitting between a fitting concave part formed on the molded article and a fitting convex part provided on another object is increased. SOLUTION: A polyurethane coating 74 of a steering wheel 70 has a surface portion 7 formed by injecting a polyurethane material U1 for a surface portion into a cavity under reduced pressure. 5 and the polyurethane material for internal use U in the cavity under reduced pressure. 2 is an RIM polyurethane two-color molded product comprising an interior 76 formed by injecting 2. Spoke part 72 In the recess 77 of the polyurethane coating 74 of the A fitting concave portion 78 for fitting the fitting convex portion 81 is formed on the inner periphery thereof. 9 are formed.
