ONE-WAY CLUTCH, DRIVE TRANSMISSION UNIT USING THE ONE-WAY CLUTCH, INKJET RECORDING DEVICE USING THE DRIVE TRANSMISSION UNIT
Document Type and Number:
Japanese Patent JP2021134918
Kind Code:
A
Abstract:
To provide a one-way clutch having good rotational stability of a driving force transmission member, and capable of reliably functioning.SOLUTION: A one-way clutch 16 that is fitted and inserted into a fixed shaft member 11s, comprises a driving force input member 17, a driving force output member 19, and a driving force transmission member 18 that can move in a thrust direction between the driving force input member and the driving force output member. The driving force input member comprises a second engagement part 17d that can engage with a first engagement part 18d. The driving force output member comprises a second ratchet engagement part 19d that can engage with a first ratchet engagement part 18u. When the driving force input member rotates in a forward direction, the second engagement part rotates forward in a state of engaging with the first engagement part, thrusts the driving force transmitting member upward, and at the same time, rotates the driving force output member in the forward direction. When the driving force input member rotates reversely, the ratchet engagement part thrusts the driving force transmission member downward to separate it from the second ratchet engagement part, thereby preventing the driving force output member from rotating reversely.SELECTED DRAWING: Figure 5
