  • Publication number: 20250073839
    Abstract: The sander includes a sanding part having a planar sheet placement surface on which a sanding sheet can be set, and a clamping mechanism configured to hold the sanding sheet on the sanding part. The clamping mechanism includes a clamping part configured to hold the sanding sheet and to be slid in a direction parallel to the sheet placement surface between a closed position to hold the sanding sheet and an open position to allow removal of the sanding sheet, an elastic element that applies a biasing force of biasing the clamping part toward the closed position, in a direction parallel to the sheet placement surface, and a holding mechanism configured to hold the clamping part in the open position against the biasing force. The clamping part is allowed to hold the sanding sheet when the holding mechanism is released from holding the clamping part in the open position.
