A blow-molded wheel including an axle retainer assembly. The retainer assembly (31) includes a housing (42) having transverse sleeves that support an axle (14) and a spring biased retainer pin (10) that mounts to an annular groove (12) at the axle. The housing is supported in a cavity formed into a wheel spoke (18) and a bore of a wheel hub and is retarined upon the shrinkage of the plastic around the housing. An aperture of the pin sleeve facilitates retraction of the pin and release of the wheel from the axle.

L'invention concerne une roue moulée par soufflage pourvue d'un dispositif de retenue de l'essieu. Le dispositif de retenue (31) comporte un logement (42) pourvu de manchons transversaux qui supportent un essieu (14). Le dispositif de retenue comporte également une broche de retenue (10) sollicitée par un ressort monté sur une rainure annulaire (12) de l'essieu. Le logement s'enchâsse dans une cavité formée sur un rayon (18) de la roue et dans l'alésage du moyeu de la roue. Le logement est retenu au niveau du rétrécissement du plastique autour du logement. Grâce à une ouverture de la broche, celle-ci peut être retirée plus facilement et la roue peut être libérée de l'essieu plus facilement.
