To provide an apparatus for measuring the weight capable of facilitating the installation and removal of a load cell.

This apparatus for measuring the weight for a green tea manufacturing machine is obtained by supporting a supporting point of the body thereof through a load cell 9 in an installation part of the body of the green tea manufacturing machine, installing an actuator in the vicinity of the load cell 9 and making the load cell 9 freely detachable from the body of the green tea manufacturing machine. Thereby, the apparatus for measuring the weight of a steamer and a leaf beater of the green tea manufacturing machine is simplified to reduce the cost and the load cell 9 can be prevented from being broken. Furthermore, the checking and exchange of the load cell 9 are facilitated and the operation of this machine can be stabilized without measuring the weight to carry out the cleaning and repair of this machine without anxiety.
