摘要： A sheet conveying device includes an abutment that abuts on a sheet conveyance path through which a sheet is conveyed. A holder supports the abutment and pivots to move the abutment between an abutting position where the abutment abuts on the sheet conveyance path and a retracted position where the abutment retracts from the sheet conveyance path. A biasing member applies a biasing force to the abutment. The biasing force moves the abutment from the retracted position toward the abutting position. A restrictor restricts motion of the abutment against the biasing force at the abutting position. An adjuster adjusts the biasing force applied to the abutment situated at the abutting position.
