た不都合がない効果を有する。 In the drawings, reference numeral 1 indicates a valve-driving camshaft that is linked to the crankshaft of the engine, and the shaft 1 has a cam sprocket 2 in the middle, and a pair of valve-driving cams 4 in each of its outer half portions 3. Furthermore, each half 3 is supported at both ends by respective bearings 5, 5, and an electric angle sensor 6 is provided therebetween, located between the two bearings 5, 5. The sensor 6 is connected to the rotor 6a on the shaft 1.
and a pick-up coil 6b on the outside thereof, and the rotor 6a is preferably located between the pair of cams 4, 4 on the shaft 1 as shown in the figure. As shown in the second figure, the rotor 6
It is also possible to make the rotor 6a integrally with one of the cams 4, 4, in other words, to configure the rotor 6a on the cam 4. When the device of the present invention is applied to a DOHC type engine, it is as shown in FIGS. 3 and 4, for example. In this case, the engine is for a two-wheeled motor vehicle and is installed tilted forward on the vehicle body, and the camshaft 1 has a left half 3 for the intake valve and a right half 3 for the exhaust valve. Each half part 3 has a pair of valve train cams 4 on the right side and a left side, and each half part 3 has two bearings 5, 5,
5 is now supported. In the illustrated one, a rotor 6a is provided between the bearings 5, 5 between the right end and the middle part of the left half 3 for the intake valve, and this rotor 6a cooperates with the pick-up 6b above the rotor 6a to form an angle sensor 6. Then, a cover 7 was applied on the upper side. In this way, according to the present invention, the valve train camshaft is of a type supported by at least two bearings, and the angle sensor is arranged between the bearings, thereby effectively utilizing the space existing between the bearings. be able to,
It has the advantage of not having the above-mentioned disadvantages of the conventional type and the type provided at the end of the shaft.
