Abstract

PURPOSE:To accomplish power transmission of a belt reliably from the low- speed rotation of an engine without damaging power transmission and to reduce transmission loss by forming a small hole on a differential pressure adjusting piston for communicating a low pressure portion with a high pressure portion, which are provided on both sides of the piston. CONSTITUTION:As a small hole 43b is disposed on a differential pressure adjusting piston for communicating a low-pressure portion and a high pressure portion which are provided on both sides of the piston, when the flow of pressure fluid supplied from a pressure fluid supply source is small, the pressure fluid passes through the small hole 43b to flow in the low-pressure portion 45. Thus, the pressure on low pressure side amounts to a designated value earlier, and after that, the pressure on high pressure side amounts to a designated value. Accordingly, even if the speed is changed from the low speed of an engine, the pressure on low pressure side amounts to a designated value earlier than the pressure on high pressure side to secure designated side pressure, so that transmission loss during the above period can be reduced.
