A mechanical pencil having a rotational drive mechanism which gradually rotates a writing lead on application of writing pressure and allowing rotational operation of the writing lead to be known reliably. First and second cam facesandare respectively formed at one end face and the other end face of a rotorin an axial direction, and first and second fixed cam facesandarranged on the body cylinder side so as to respectively face the first and the second cam faces are provided to form the rotational drive mechanism for the writing lead. A plurality of groovesin the axial direction are formed at a sliderof a pipe endwhich projects forwardly from a body cylinder. Therefore, the user can see the grooves(provided for the slider) rotated by rotation of the rotor

With the above-mentioned structure, a pipe-slide type mechanical pencil can maintain an amount of projection of the writing lead from the pipe end within a certain range.

A chuck () for grasping a writing lead and a rotor () arranged to be movable in a direction of rotation and an axial direction within a body cylinder (). By axial movement of the rotor in conjunction with writing operation, the rotor rotates and the writing lead is also subjected to rotational movement. The writing lead can be inched out of the chuck by way of knock operation of the knock cover () arranged at a rear end port ion of the body cylinder. A separation part having a gap (G) is formed at any location along a knock operation transmitting path between the above-mentioned knock cover and the above-mentioned chuck, the separation part transmits the above-mentioned knock operation to the above-mentioned chuck and inhibits rotation operation from being transmitted.

A chuck () for grasping a writing lead and a rotor () arranged to be movable together in a direction of rotation and an axial direction within a body cylinder (). A rotational drive mechanism for the writing lead is formed such that first and second cam faces () and () are respectively formed at one end face and another end face of the rotor in the axial direction, and first and second fixed cam faces () and () are arranged on the body cylinder side to face the above-mentioned first and second cam faces respectively. Retreat operation and forward movement (cushion action) of the writing lead by writing pressure are provided with a damping effect by sticky grease () interposed between a stopper () and a torque canceller (). As a result, a sense of uncomforting, when writing, generated in conjunction with the cushion action can be reduced.

A rotational drive mechanism for the writing lead is formed such that first and second cam faces () and () are respectively formed at one end face and another end face of the rotor in the axial direction, and first and second fixed cam faces () and () are arranged on the body cylinder side to face the above-mentioned first and second cam faces respectively. A pipe end () for guiding the writing lead to interlock with retreat and forward movement of the writing lead while the writing proceeds is arranged to move in the same direction, in conjunction with retreat and forward movement of the above-mentioned chuck.

A chuck () for grasping a writing lead and a rotor () arranged to be movable in a direction of rotation and an axial direction within a body cylinder (). A rotational drive mechanism for the writing lead is formed such that first and second cam faces () and () are respectively formed at one end face and another end face of the rotor in the axial direction, and first and second fixed cam faces () and () are arranged on the body cylinder side to face the above-mentioned first and second cam faces respectively. An indicator () of a wedge-shaped notch is formed at a part of the rotor. The indicator can be observed through the body cylinder made of a transparent material. By this structure, a mechanical pencil is provided in which operation of the writing lead that is gradually rotated by way of writing pressure can be known certainly.

A passenger detection apparatus includes sensors arranged on a seat in a vehicle; shield cables corresponding to the sensors, wherein one end the core wire is connected to the corresponding one of the sensors; a measurement signal output device for outputting a measurement AC signal; a device for detecting a current output from the measurement signal output device; a device for outputting a capacitance canceling AC signal, which has the same phase and the same level as those of the measurement AC signal; a device for selectively applying one of the measurement AC signal and a DC voltage to the other end of each shield cable; and a device for selectively applying one of the capacitance canceling AC signal and a second signal, which has a different waveform from that of the measurement AC signal, to the shield of each shield cable.

A float bowl type carburetor has a fuel and air mixing passage extending therethrough, a float bowl assembly, a priming pump communicated with the float bowl assembly and a fuel supply pipe that is communicates fuel in the float bowl assembly with the fuel and air mixing passage. The priming pump is operable to deliver pressurized fluid into the float bowl assembly in the area of the fuel supply pipe. Preferably, the priming pump discharges fluid in line with the fuel supply pipe so that at least some of the fluid discharged from the priming pump flows directly into the fuel supply pipe to facilitate delivering a rich fuel and air mixture to the engine to facilitate starting the engine.

A writing implement, wherein elements forming a reverse flow prevention mechanism are formed in rather simple shapes and assembly process for the reverse flow prevention mechanism is rather simplified. The reverse flow prevention mechanism () comprises a valve chamber (), an inflow port () opened to the ink storage part () side of the valve chamber (), an outflow port () opened to the writing tip () side of the valve chamber (), a valve element () stored in the valve chamber (), a restricting body () stored in the valve chamber () at a position on the outflow port () side of the valve element (), and a valve seat () formed around the inflow port (). When the writing tip () is faced upward, the inflow port () is closed by the valve element (), and when faced downward, the valve element () is allowed to touch the restricting body () and does not reach the outflow port ().
