A mechanical pencil includes a ball chuck, a rotation drive mechanism having a rotary part, a feedout cam face having a step part in the axial direction, an input member rotating upon receiving a rotational drive force of the rotary part, and an output member having an abutting part abutting against the feedout face and a slider provided with a holding chuck holding lead, the abutting part moves along the feedout face corresponding to rotation of the output member and so that advancing motion of the slider when the abutting part drops into the drop difference causes lead held by the holding chuck to be pulled out by the ball chuck, and further including a clutch mechanism transmitting rotational movement of the input member to the output member.
