ROLLER SUPPORT MECHANISM, ROLLER UNIT, AND FIXING DEVICE

摘要

A roller support mechanism supports a rotary shaft of a second roller disposed in parallel with a first roller. The roller support mechanism includes a support frame, a cover member, a bearing member, and an urging member. The support frame is made of sheet metal and has a support groove extending in a direction away from the first roller and receiving the rotary shaft. The cover member is made of sheet metal and is attached to the support groove to cover a pair of side edge sections facing each other across the support groove. The bearing member is made of resin and has a bearing groove that rotatably supports the rotary shaft. The bearing member is disposed in the support groove, with the cover member interposed therebetween, so as to be movable in a direction toward/away from a bottom of the support groove. The urging member urges the bearing member in a direction away from the bottom of the support groove.
