The invention claimed is: 1. A force-on-pedal sensor comprising: a cylindrical substrate whose one end is closed having: a hole at a center of a side section of the cylindrical substrate; and a strain resistance element via an insulating layer at the side section of the cylindrical substrate; a coil spring coaxially inserted from an open end of the substrate; an inputting shaft having a stepped part contacted with one end of the coil spring and inserted in the hole in such a manner that a part of the inputting shaft is protruded from the hole; and a stopper at a position where the inputting shaft is protruded, wherein a first stopper having an outer diameter larger than an inner diameter of a cylindrical section of the substrate is inserted into the stepped part of the inputting shaft, and contacts the coil spring, wherein when the coil spring is contracted to a certain load, the first stopper contacts the substrate, so that no more load is applied. 2. The force-on-pedal sensor of claim 1, wherein a screw section is formed at an outer circumference of a cylindrical section of the substrate. 3. The force-on-pedal sensor of claim 1, wherein the substrate is formed by mechanically coupling the side section with a cylindrical section, and the strain resistance element and a processing circuit are formed in one piece at the side section. 4. A pedal-pressure detecting device comprising: a brake arm; a link whose one end is linked with the brake arm using a rotatable first shaft and the other end is linked with a push-rod which transmits force to a master cylinder; and an arm, which is installed at the link, for transmitting a load by contacting the inputting shaft of a force-on-pedal sensor comprising: a cylindrical substrate whose one end is closed having: a hole at a center of a side section of the cylindrical substrate; and a strain resistance element via an insulating layer at the side section of the cylindrical substrate; a coil spring coaxially inserted from an open end of the substrate; an inputting shaft having a stepped part contacted with one end of the coil spring and inserted in the hole in such a manner that a part of the inputting shaft is protruded from the hole; and a stopper at a position where the inputting shaft is protruded. 5. A pedal-pressure detecting device comprising: a brake arm; a link whose one end is linked with the brake arm using a rotatable first shaft and the other end is linked with a push-rod which transmits force to a master cylinder; and an arm, which is installed at the link, for transmitting a load by contacting the inputting shaft of the force-on-pedal sensor of claim 2. 6. A pedal-pressure detecting device comprising: a brake arm; a link whose one end is linked with the brake arm using a rotatable first shaft and the other end is linked with a push-rod which transmits force to a master cylinder; and an arm, which is installed at the link, for transmitting a load by contacting the inputting shaft of the force-on-pedal sensor of claim 1. 7. A pedal-pressure detecting device comprising: a brake arm; a link whose one end is linked with the brake arm using a rotatable first shaft and the other end is linked with a push-rod which transmits force to a master cylinder; and an arm, which is installed at the link, for transmitting a load by contacting the inputting shaft of the force-on-pedal sensor of claim 3. 8. The pedal-pressure detecting device of claim 4, wherein a universal joint section is formed at a load applied point between the arm and the inputting shaft. 9. The pedal-pressure detecting device of claim 5, wherein a universal joint section is formed at a load applied point between the arm and the inputting shaft. 10. The pedal-pressure detecting device of claim 6, wherein a universal joint section is formed at a load applied point between the arm and the inputting shaft. 11. The pedal-pressure detecting device of claim 7, wherein a universal joint section is formed at a load applied point between the arm and the inputting shaft.
