摘要： An object of the present invention is to maintain a predetermined positional relationship between an outer pin holder and a housing in a speed reducer section B, to prevent damage to such components as revolving members, outer circumferential engagers, and motion conversion mechanism upon a large axial load due to turning or sudden acceleration/deceleration, and to eliminate rattling noise caused by a housing and the outer pin holder. An elastic member is disposed on one or both axial end surfaces of the outer pin holder, between the outer pin holder and the housing. As a result, even if there is an axial load exerted on the outer pin holder, the outer pin holder is always held at a predetermined position by restoring force from the elastic member(s), in a proper positional relationship with the housing.

摘要： A spring clutch is provided for which durability is improved by preventing a clutch spring from breaking due to fatigue. A cylindrical clutch spring made from a wire having a square section is mounted between a pulley and a pulley hub mounted in the pulley. An end of the clutch spring is coupled to the pulley hub. A clutch surface is formed on the inner periphery of the pulley and is formed with a large-diameter recess at a position opposite to the end portion of the clutch spring including the torque transmission end. When the pulley rotates in one direction, the clutch spring expands. At this time, the end portion of the clutch spring including the torque transmission end expands in the large-diameter recess, thus relaxing sharp torque produced in the clutch. This prevents local stress concentration on the clutch spring and breakage of the clutch spring and improves the durability of the clutch.

摘要： Musical sound signal is input to an electronic volume control unit, which in turn adjusts the gain of the input musical signal and outputs the resultant gain-adjusted signal to an amplifier. CPU supplies the electronic volume control unit with a sound volume setting level corresponding to an output of a rotary encoder. At the same time, the CPU generates, with reference to stored data of a ROM table, a hue control signal for changing a displaying hue of a three-color light-emitting diode in accordance with the sound volume setting level supplied by the CPU. The CPU takes in a current sound volume setting level when an upper-limit setting switch is activated, and it retains the taken-in level as an upper limit value of various sound volume setting levels that are to be used to change the displaying hue of the light-emitting diode between purple and red hues. As the sound volume setting level is changed from zero to the upper limit value, the displaying hue changes in a stepwise manner.
