Description of the Invention [Technical Field] The present invention relates to an improved angular position sensor which is not formed between the outer casing and the rotating shaft. Damage due to differential vibration (Differential Vibrati〇n). [Prior Art] The angular position sensor can detect the angular orientation of the rotating shaft with respect to the outer casing. For example, when the rotating shaft rotates with the vertical axis as the axis, the angle of the rotating shaft is monitored to accurately grasp the angular position of the rotating shaft at a particular angular position. Azimuth is necessary. In the position of the non-suspended near bearing, the rotating shaft will show a slight radial (vertical axis direction) vibration. Since the rotating shaft is not perfectly symmetrical with its own axis, and the bearings located along the rotating shaft are not perfectly aligned with the axis of the rotating shaft, when the rotating shaft rotates, a certain degree of radial vibration or difference is received between the bearings along the rotating shaft. Speed vibration. & The conventional angular position sensor is a combination of a wheel fixed around the rotating shaft and a brush in contact with a ring-shaped resistor fixed to the stationary member. Applying a potential through the resistive member to the brush and detecting the current through the resistive member provides an angular orientation drop of the brush relative to the resistive member. Mussels In order to accommodate differential vibration, the shape of the stationary members is a loose clamshell structure that is joined to each other and wound around the runner. The stationary clamshell: the knot 2 is fixed on the outer casing through which the bearing passes. Therefore, the runner can vibrate synchronously with the rotating shaft within the 1252908 clamshell structure of the static I. At present, the angular position sensing port is a two-port [5-knife including the runner and the clamshell-like structure are made of plastic, and the differential vibration occurring on the plastic runner in the clamshell structure will make the runner and the runner The clam shells are in contact with each other. The friction generated by the contact of one of the rotating wheels with the clamshell casing creates plastic particles that are disturbed inside the clamshell casing, and these plastic particles interfere with the brush and the resistive surface of the stationary member. This interference between the brush and the ring-shaped resistor substrate can cause the instrument to produce an incorrect angular position reading. It is therefore necessary to provide an improved angular position sensor whereby the parts do not vibrate with each other when the wheel rotates in synchronism with the rotating shaft. SUMMARY OF THE INVENTION Briefly, the present invention specifically exhibits an angular position sensor to determine the angular orientation of the phase axis of the housing. The angular position sensor includes a turn = 'this wheel has a bore that can accommodate the shaft, and a fixture that can rotate the wheel and the shaft in five steps. The runner also has a ring-shaped male bearing surface. The angular position sensing stomach further includes a female bearing surface (four) - a runner, a hub, and a surface of the female bearing complementary to the surface of the male bearing on the runner. The surface of the female bearing of the first runner 12 is combined with the surface of the male bearing on the runner. When the first rotor=the outer hub vibrates simultaneously with the runner and the shaft, the runner can be allowed to be in the first runner Rotate undisturbed. Similar to the conventional angular position sensor, the angular position sensing 1252908 of the present invention has a ring-shaped resistive substrate on the rotor casing or the wheel, and a ring resistor on the runner casing or the wheel. The brush in the opposite position. In combination with the brush and the resistive substrate, applying a potential through the resistive member and the brush, and detecting the current through the resistive member, the angular orientation reading of the brush relative to the resistive member can be displayed. According to the present invention, the positional sense of the present invention is such that it allows the reel to be oscillated relative to the outer casing of the support shaft. A plurality of spring members are interposed between the first reel housing and the second reel housing: the first to the second wheel, and the outer cymbal, are fixed in a movable manner. In the two embodiments, the annular gasket is mounted between the periphery of the inner casing and the inner periphery of the outer casing to permit movement of the inner casing relative to the outer casing. [Embodiment] Referring to Figure 1, it is shown that the shank M 々 ^ 3 is not attached to the rotating shaft 1 according to the prior art and is fixed by a clamp (not shown; as is known to those skilled in the art) The sense of angular position on the bracket 14 of the force seat: seeing the eyes crying 16, 17〗...: The shaft 12 is supported by a fine 17 or 18 kg, and the shaft 2 turns as a rotating shaft.
