摘要:
A washing machine according to the present invention includes a pressure sensor provided at a rod holding plate holding a suspension rod with which an outer tub is suspended. The pressure sensor is constructed so that a coil is wound around a magnetostrictive element whose magnetic characteristic changes when it is expanded, compressed or twisted by an external force. The change in the magnetic characteristic is converted to the change in the inductance of the coil, and an oscillating signal of a frequency corresponding to the inductance generated. Based on the frequency of the signal, the load on the pressure sensor is detected. Before supplying water, the amount of the laundry contained in a wash-and-extraction tub is detected based on the output of the pressure sensor, and an object water level corresponding to the amount is determined. After that, a water supply valve is opened to start supplying water into the wash-and-extraction tub. The weight of water supplied is monitored based on the output of the pressure sensor, and the weight is converted to a water level. When the monitored water level has attained the object water level, the water supply is stopped. Thus, the pressure sensor functions not only as a load detector but also as a level sensor.

A retracting mechanism for storing or erecting a mirror includes, at a coupled portion of an output shaft of a drive motor and a worm gear, coupling retaining portions fitted together in a press-fitted state and rotational force transmitting portions opposing each other in a state where a predetermined gap is present between them. The coupling retaining portions are configured by a circular shaft portion and a circular fitting hole, and the rotational force transmitting portions are configured by a double D-cut portion and double D-protruding portions. The rotational force of the output shaft is transmitted by the rotational force transmitting portions, and the coupled state of the output shaft and the worm gear is retained on the same axial line and the slanting of the worm gear is prevented by the coupling retaining portions.

An abnormal voltage detection circuit includes a series circuit of a resistor and a capacitor coupled across a power source by means of a switch, an inverter with the input terminal coupled to the junction of the resistor and capacitor, and an R-S flip-flop circuit with the set and reset input terminals coupled to the output terminal of the inverter and a manual switch respectively. The R-S flip-flop circuit is set by a first threshold voltage lower than the threshold voltage of the inverter, and reset by a second threshold voltage higher than the threshold voltage of the inverter.

The operation torque during disengaging of clutch projections out of clutch grooves, is effectively suppressed from excessively increasing immediately after start of device assembling. In a door mirror device, a gear plate has clutch grooves made substantially in trapezoidal form, in circumferential cross-section, increasing in width from a groove bottom to an opening end. A clutch disk has clutch projections made substantially in trapezoidal form, in circumferential cross-section, decreasing in width in taper form from a base toward a tip wherein the top surfaces are made in an inverted radial form decreasing in width from inner periphery to outer periphery. Due to this, when a torque exceeding a set value is transmitted to the gear plate, the pressure-contact area of the clutch projection with the clutch groove gradually moves from inner periphery to outer periphery while moving the clutch disk upward against a bias force of a clutch spring.

In a door mirror device for a vehicle, a first helical gear and a second worm gear are rotated integrally by a first worm gear. In this way, the second worm gear is rotated around a second helical gear, and a mirror is retracted or extended. The first helical gear and the second worm gear can tilt. Rotating central shafts thereof are supported at both ends by first bearings and second bearings, respectively. Even if load is applied from the first worm gear or the second helical gear to the first helical gear or the second worm gear, it is possible to suppress integral tilting of the first helical gear and the second worm gear. Accordingly, when the mirror is retracted and when the mirror is extended, it is possible to suppress a change in a sound of operation and to make the sound of operation uniform.
