要ならば、新たな前進運動に備える。Advancement of the wick (not shown) is initiated by pressure on the pushbutton 5, which, against the action of the main spring 70, moves forward (on the left in the figure) of the entire central tube 4-ring 6-grip 10. , so that the front part of the jaw 11 . 11 ′ is moved into the cavity 16 . This movement thus advances the wick, which is clamped between the jaws 11.degree. 11', across the rubber retaining ring 14 and across the tip of the head 6 in the outlet passage 15. When the pressure on the pushbutton 5 is released, the central tube 4-ring 6-
The entire gripping body 10 returns to the rear under the action of the main spring, and during this backward movement the jaws 11 then located in the cavity 16
, 11' can be opened and moved without retracting the core until the jaws 11, 11' are tightened back into the cone 12 when they again engage the core. The device is then ready for a new forward movement, if necessary.

とく動かない。Furthermore, a brake spring 16 disposed around the forward end of the central tube 4 is supported forwardly at the rearward end of the socket 9 and rearwardly at the forward end of the knurled male member 17;
The thread is provided with a skirt portion 18 extending inside the tubular member 1 with the head 6 facing rearward. As shown in the accompanying drawings, the knurled male member 17 is connected to the brake spring 16.
It is made to adjust. With respect to the lower part of the figure, the spring 16 is in its normal use position, and when in the upper part of the figure, the knurled male member 17 is screwed in so that the spring 16 is fully compressed and thus of the fixed core. It doesn't move at all.

きる。In this way, when the brake spring 16 is in its normal position of use, the pressure on the core is applied slightly towards the rear, against the action of the spring 16, when the user is writing, for example. 1
0-Socket 9-Central tube 4-Push button 5 There is a tendency to press the whole. Therefore, the mechanical pencil according to the invention has a braking effect during use, which presents a comfortable writing flexibility to the user and considerably reduces the risk of breakage when shocks are applied to the lead. Furthermore, by means of the knurled male member 17, the force of the brake spring 16 can be adjusted by the force that the user applies to the lead when writing or sketching.
