自転車の車輪用ハブ本体およびそのハブ本体を備えるハブ
Document Type and Number:
Japanese Patent JP4761857
Kind Code:
B2
Abstract:
A hub body (10) for a bicycle wheel, comprising a substantially tubular body (20) extending along a longitudinal axis (X-X) and provided with a pair of opposite end portions (25,26), at least one of which comprising an annular front surface (35,36) on which a plurality of housing seats (45,46,47) for an end portion (110,120) of respective spokes (100) are formed. Advantageously, at least some of these seats comprise retention means (80,81) adapted to prevent said spokes (100) from moving along a direction substantially parallel to said longitudinal axis (X-X) in all operating conditions. The spoke is thus prevented from moving away from the hub in the case of untightening or breaking of a spoke during a race, which would compromise the correct operation of the wheel and/or constitute a danger to the cyclists.
