Telescopic shaft for rotational torque transmission.

摘要: A telescopic torque transmission shaft comprises a pair of shafts (3, 4) telescopically engaged to each other. The are formed into polygon shafted configuration. At least two leaf springs (11) with predetermined length provided along different plans on the inner one shaft. Roller bearings (16) also between coupled portion be biased onto periphery outer for eliminating play and maintaining smoothness relative axial movement assuring transmission, whereby successfully eliminate uncomfortable noise.
