Claims

[Scope of Claim for Utility Model Registration] 1. A scale body is suspended via a hanging hook, and an object to be weighed is suspended from the scale body via a weighing hook, and the weight of the object is measured. In the portable hanging scale, the base end side of the hanging hook is loosely inserted into the scale body from the outside of the scale body, and the scale body and the hanging hook are connected to the loosely inserted base end side. An elastic body is interposed so as to be relatively movable against the elastic biasing force in the hanging direction of the scale body in a suspended state, and the elastic body is engaged with a predetermined portion of the hanging hook. The contact point is closed in a state where the scale body and the hanging hook move relative to each other against the elastic urging force of the elastic body, and the scale body and the hanging hook move in accordance with the elastic urging force of the elastic body. A portable hanging scale characterized by being provided with a power on/off switch whose contacts open in a state of relative movement. 2. The predetermined portion of the hanging hook is a support portion that is provided on the base end side of the hanging hook and supports the elastic body interposed on the base end side against the elastic biasing force of the elastic body. The portable hanging scale according to claim 1, characterized in that: 3. The portable hanging scale according to claim 1 or 2, wherein the elastic body is a coil spring disposed coaxially on the proximal end side of the hanging hook.
