Pressing device, in an image forming apparatus that includes an adjuster connected to two lateral plates

摘要

A pressing device includes a pressing member, a first lateral plate including a first connecting portion to support a first end of the pressing member, a second lateral plate including a second connecting portion to support a second end of the pressing member opposite to the first end, a first adjuster connected to the first lateral plate at the first connecting portion and to the second lateral plate at the second connecting portion, and a biasing member. The biasing member biases at least one of the first lateral plate, the second lateral plate, and the first adjuster to press the pressing member against the target in a pressing direction. The first adjuster is connected to the first lateral plate and the second lateral plate such that a relative position of the second connecting portion relative to the first connecting portion is changeable in the pressing direction.

主权项

1. A pressing device, comprising:
a pressing member including a first end and a second end opposite to the first end in a longitudinal direction of the pressing member, to contact a target; a first lateral plate including a first connecting portion, to support the first end of the pressing member; a second lateral plate including a second connecting portion, to support the second end of the pressing member; a first adjuster connected to the first lateral plate at the first connecting portion and to the second lateral plate at the second connecting portion to regulate relative movement of the first lateral plate and the second lateral plate in the longitudinal direction; and a biasing member to bias the first adjuster to press the pressing member against the target in a pressing direction, wherein the first adjuster is connected to the first lateral plate and the second lateral plate such that a relative position of the second connecting portion relative to the first connecting portion is changeable in the pressing direction, the first adjuster is connected to the first lateral plate and the second lateral plate by corresponding elongated holes extending in the pressing direction and corresponding fastening members inserted into the corresponding elongated holes, and a biasing force of the biasing member is transmitted from the first adjuster to the first lateral plate and to the second lateral plate via the corresponding fastening members.
