A mechanical pencil including a main body divided into first and second members which are rotatable relative to one another. An inner mechanism is provided, primarily in the first member of the body, including a chuck for gripping leads, a chuck tightening member for tightening the chuck disposed around the chuck, a chuck tightening member receiver, and a lead case coupled at a front end portion to the chuck. In a preferred embodiment, a push member is coupled at a front end to the lead case while a spring biases the inner mechanism rearwardly. A mechanism is provided for converting the relative rotation of the first and second members to axial movement of the inner mechanism between retracted and writing positions.
