Summary:A method for manufacturing a rod includes a step of preparing a hollow first member and a second member formed so as to have a portion smaller in outer diameter than an outer diameter of the first member, a restraining step of placing a restraining member into abutment with an outer peripheral surface of the first member, a step of moving an inner peripheral surface of the first member and an outer peripheral surface of the second member closer to each other while rotating at least one of the first member or the second member, and a step of joining the first member and the second member by welding with the aid of friction by axially pressing in the first member and the second member by a predetermined amount after placing the inner peripheral surface of the first member and the outer peripheral surface of the second member into contact.
