ONE-WAY CLUTCH, DRIVE TRANSMISSION UNIT USING THIS ONE-WAY CLUTCH, AND INKJET PRINTING APPARATUS USING THIS DRIVE TRANSMISSION UNIT

摘要

A one-way clutch including: a driving force input member; a driving force output member; and a driving force transmitting member, wherein, when the driving force input member performs forward rotation, the second engaging part performs forward rotation in a state of being engaged with the first engaging part, so as to connect the first ratchet engaging part and the second ratchet engaging part, in order to make the driving force output member perform forward rotation, wherein, when the driving force input member performs reverse rotation, the second engaging part performs reverse rotation in a state of being engaged with the first engaging part, so as to make the driving force transmitting member and the first ratchet engaging part perform reverse rotation so that the first ratchet engaging part is separated from the second ratchet engaging part, in order not to make the driving force output member perform reverse rotation.
