摘要： PROBLEM TO BE SOLVED: To reduce the noise of a bearing part and electric power consumption and to provide the sufficiently high detection accuracy of a laundry amount by using a needle bearing for a bearing for rotatably supporting a washing shaft inside a dehydrating shaft in a washing machine provided with the dehydrating shaft and the washing shaft concentrically. SOLUTION: The needle bearing 39 is used for the bearing for rotatably supporting the washing shaft 37 inside the dehydrating shaft 35. Since the needle shaft 39 is a rolling bearing and brought into contact with a shaft on a line extended in the axial direction of the peripheral surface of a needle, it is sufficiently suitable for use in the conditions of applying high loads and is suitable as the bearing of a dehydrating and washing machine driving part. Then, frictional resistance is made small and the noise is reduced by a slide shaft. Also, the consumption of electric power is reduced by the smallness of the frictional resistance. Further, even in the one of detecting the rotation degree of a motor to washing loads and judging the laundry amount, the sufficiently high detection accuracy is obtained.

摘要： PURPOSE: To reduce operating sound of a reduction gear mechanism and bumping sound in reversing motion of an agitating body. CONSTITUTION: A lower washing shaft 33 is penetrated through the inside of a lower vessel shaft and an input gear 41 of a reduction gear mechanism is formed of the upper part of the lower washing shaft 33. This input gear 41 is composed of a helical gear. An elastic body 44 to be a pressuring means is interposed between a flange part 33b under the input gear 41 of the lower washing shaft 33 and the upper face of a bearing metal 34. The elastic body 44 is made of metal and formed in a doughnut shape disc bent as the whole body and is elastically deformed in the shaft direction. The lower washing shaft 33 is pressed and energized to the shaft direction, for instance to the upward direction.

摘要： PURPOSE:To prevent a tumbler from corotating in washing operation and components from being damaged when power stoppage, etc., by providing a driving part which locks the tumbler with a locking part engaged with an engaging part when energized to drive, and releases when shut off. CONSTITUTION:Even though the tumbler of a washing machine stops in an position randomly, and a notch 31b is not lined up underneath a pawl 34a of a lock lever 34, electromagnet 37 is energized to drive and the lock lever 34 is turned, and the pawl 34a of the lock lever 34 comes into contact with the periphery of an upper flange 31a of a brake drum 31. With this state, when the tumbler corotates, the pawl 34a of the lock lever 34 travels while being in contact with the periphery of the upper flange 31a of the brake drum 31 relatively, and when the notch 31b lines up underneath the pawl 34a, the pawl 34a is engaged with the notch 31b. Thus, the tumbler is locked and prevented corotation after this.

摘要： PURPOSE:To prevent the generation of noise when a clutch lever engages with a click portion of a sleeve by installing a cylindrical member made of an elastic material on the sleeve in such a manner as to surround the click portion. CONSTITUTION:A cylindrical member 21 is made of an elatic material such as a nitrilobutadiene rubber or the like, fitted to a sleeve 15 in such a manner as to be tightened, and installed in such a manner as to surround the respective click portions 16. When an engaging element 17a of a clutch leer 17 is engaged with the click portion 16 of the sleeve 15 by spring force, the cylindrical member 21 made of an elastic material is interposed there between, whereby the collision of the clutch lever 17 is born by the cylindrical member 21 so as to restrain the generation of collision noise. Furthermore, it is enough to simply install the cylindrical member 21, so that the constitution can be simplified.

摘要： PURPOSE:To prevent the concentration of stress on an extended part of a coil spring and to improve the reliability on strength of a coil spring by fixing a connector to a pint so that an extension line of an extended part of a coil spring coincides with a center of a pin installed at a stationary part and by reducing a stress placing on an extended part. CONSTITUTION:While a central axis of an extended part 37 is placed at an approximately central axis of grooves 39a, 40a of a connector 38, a pin 41 is fixed at a stationary part such as an inner bottom part of a lower housing 13. And the connector 38 is fixed to this pin 41 by having through the adapter hole 38a on it so that an extension line of the extended part 37 coincides with the center of the pin 41, as the center of the adapter hole 38a of the connector 38 is placed on the extension line of the extended part 37 of the coil spring 36. By this, the stress on the extended part 37 of the coil spring 36 is fairly reduced, and the stress can be made smaller than a yielding point of a spring wire rod of the coil spring 36. Therefore, the reliability on strength of a coil spring 36 can be improved.
