PROBLEM TO BE SOLVED: To provide an elevator hoisting machine capable of improving assembly workability by making it unnecessary to concurrently drill holes for a member for connecting a sheave and a rotor, into the sheave and the rotor.SOLUTION: An elevator hoisting machine includes a rotor 3, a stator 1a that imparts a rotational force to the rotor, and a sheave 4 that is connected to the rotor. At least one groove is formed on a connection surface of the rotor, and at least one groove is formed on a connection surface of the sheave. At least one connection member is inserted into the groove of the connection surface of the rotor, and inserted into the groove of the connection surface of the sheave. The connection member is formed of a cold headed rivet material.
