1. A moving body control device configured to control a moving body that moves along a specific path on a surface of a specific object, the moving body control device comprising: a storage section; anda microcomputer connected to the storage section, the microcomputer being configured todetect an abnormality occurring in the moving body moving along the specific path;detect a position of the moving body as an abnormality occurrence position, in a case in which an abnormality has been detected;store, in the storage section, abnormality occurrence position information expressing the abnormality occurrence position; andcontrol an adjusting section to adjust a pressing force at which the moving body presses against the surface of the specific object, based on the abnormality occurrence position information,wherein the adjusting section adjusts the pressing force of the moving body at the abnormality occurrence position by increasing or decreasing the pressing force,wherein the microcomputer is further configured toin a case in which the pressing force has been increased,determine whether the abnormality occurring in the moving body has increased or decreased compared to the abnormality before the pressing force was increased; andcontrol the adjusting section to decrease the pressing force in a case in which the microcomputer determines that the abnormality has increased, and to increase the pressing force in a case in which the microcomputer determines that the abnormality has decreased, orin a case in which the pressing force has been decreased,determine whether the abnormality occurring in the moving body has increased or decreased compared to the abnormality before the pressing force was decreased; andcontrol the adjusting section to increase the pressing force in a case in which the microcomputer determines that the abnormality has increased, and to decrease the pressing force in a case in which the microcomputer determines that the abnormality has decreased, andwherein the specific object is a vehicle window, the moving body is a wiper, and the abnormality is chattering. 2. The moving body control device of claim 1, wherein the microcomputer is further configured to: determine whether the abnormality occurring in the moving body has increased or decreased in a case in which the pressing force of the moving body at the abnormality occurrence position has been adjusted; andcontrol the adjusting section to re-adjust the pressing force of the moving body based on a determination of whether the abnormality occurring in the moving body has increased or decreased. 3. The moving body control device of claim 1, wherein the microcomputer is further configured to store the adjusted pressing force in association with the abnormality occurrence position, in a case in which the pressing force of the moving body at the abnormality occurrence position has been adjusted. 4. The moving body control device of claim 1, further comprising a power controller that controls at least one of drive power supplied to the adjusting section from a power source, or the drive power supplied to the moving body control device from the power source, based on the abnormality occurrence position information. 5. The moving body control device of claim 4, wherein, based on the abnormality occurrence position information, the power controller causes the drive power to be supplied to the moving body control device in a case in which the moving body is within a specific range from the abnormality occurrence position, and causes the drive power not to be supplied to at least one of the adjusting section or the moving body control device in a case in which the moving body is at any position outside the specific range. 6. The moving body control device of claim 5, wherein, in a case in which a plurality of abnormality occurrence positions have been detected, the power controller causes the drive power to be supplied to the adjusting section and to the moving body control device even in a case in which the moving body is at the any position outside the specific range, based on at least one of a number of the plurality of the abnormality occurrence positions, a distance between adjacent abnormality occurrence positions from among the plurality of the abnormality occurrence positions, or a movement speed of the moving body. 7. The moving body control device of claim 1, further comprising: an abnormality detection sensor that detects the abnormality; anda position detection sensor that detects the position of the moving body. 8. A wiper system, comprising: the wiper;a wiper drive section that moves the wiper to-and-fro across the surface of a vehicle window; andthe moving body control device of claim 1.
