A stacked ringthat forms a transmission belt is formed by stacking a plurality of elastically deformable ring materialstotogether. Shot peening is performed on surfaces of the ring materialstoof the first layer as the innermost layer to the third layer so that a residual compressive stress in the ring materialstois higher than that in the ring materialstoof the fourth to sixth layers. The outer circumferential length of the ring materialof the third layer is longer than the inner circumferential length of the ring materialof the fourth layer, and the ring materialof the third layer is press-fit into the ring materialof the fourth layer.

Power transmission belt method for production thereof

A belt type continuously variable transmission includes a primary shaft and a secondary shaft, wherein the primary shaft is supported on a case via a first rolling element bearing, and the secondary shaft is supported on the case via a second rolling element bearing, the case is formed with a bolt hole at each of an even number of locations in a region separate from a shaft center plane, which is a plane that passes through a shaft center of the primary shaft and a shaft center of the secondary shaft, and first and second stopper plates that each hold down outer races of the first and second rolling element bearings are fixed to the case by bolts mounted in the bolt holes.

Belt type continuously variable transmission

A fixed sheave mounted on an input shaft and a movable sheave mounted on a cylindrical member that is slidably supported in the axial direction relative to the input shaft are respectively structured using annular members having the same shape. With this structure, the fixed sheave and the movable sheave can be common structural components, thereby enabling the structural components to be easily formed by making the shape thereof relatively simple. As a result, productivity can be further improved.

Pulley structure and belt-type continuously variable transmission

Apparatus for detecting the start and stop of an engine starter motor includes a sensor, an amplifier, a comparator, and a monostable multivibrator. When a starter motor starts and stops, magnetic flux around the starter motor varies greatly. The sensor senses this varying magnetic flux and produces a voltage signal corresponding to the magnetic flux variation. The voltage signal is amplified by the amplifier so that the amplified voltage signal is fed to the comparator. When the voltage signal fed to the comparator is greater than the reference voltage of the comparator, a pulse signal is fed to the multivibrator, and in turn the multivibrator is triggered to output detecting signals corresponding to the start or stop of the starter motor. A warning lamp or buzzer may be energized by the detecting signal from the multivibrator.
