Abstract: Provided is an electric riveter including a housing internally provided with a drive unit configured to drive an actuator that withdraws a mandrel from a rivet, and a mandrel collector that collects mandrels. The actuator includes a cover having a proximal end coupled to the housing, a nozzle provided at a distal end of the cover, and a jaw provided in the cover. The drive unit includes an electric motor that drives the actuator. The housing includes a drive housing unit connected to a handle having a rod shape. The electric motor is arranged at a position deviated from the center of grip of the handle in a direction about an axis line extending along the center line of the cover.

Abstract: The present invention provides an adjustable wrench which can suppress backlash or clearance play of a movable body with respect to a main body in all directions orthogonal to a direction in which a pair of jaws come into contact with and separate from each other. An adjustable wrench further includes first urging means that urges a columnar portion such that the columnar portion is held in a state in which an axis of the columnar portion crosses an axis of a guide hole portion at an inclined angle in each of both a direction from the axis toward an open portion in the guide hole portion and a direction orthogonal to the above direction and the axis of the guide hole portion.
