The oil passage (201) includes: a first oil passage (201d) for feeding the oil pressure to the pressure regulator valve (25); and a second oil passage (201e) for feeding the oil pressure from the pressure regulator valve (25) to the hydraulic servo (28). The pressure regulator valve (25) includes: a valve member (250); an input port (254) connected to the first oil passage (201d); an output port (255) connected to the second oil passage (201e); and a drain port (257) connected to a drain oil passage (EX). The valve member (250) has: a first pressure receiving area (A₁) to be fed with the feedback pressure of the second oil passage (201e) in a direction to provide the communication between the output port (255) and the drain port (257); a second pressure receiving area (A₂) to be fed with the signal pressure (P SLU ) in a direction to provide the communication the output port (255) and the drain port (257); and a third pressure receiving area (A₃) having an area different from that of the second pressure receiving area (A₂). The signal pressure generating means (SLU;...) feeds the signal pressure to the third pressure receiving area (A₃) at all times and the signal pressure (P SLU ) selectively to the second pressure receiving area (A₂).

摘要： The rocking edge distance difference (δ) in a block (Ba) composing a drive belt and the clearance in a Y-direction (Cy) between a dimple (Pj) and a hole (Ha) are set in a predetermined relation. Even if the block (Ba) is inclined by a moment to be caused according to the rocking edge distance difference, the interference between the dimple (Pj) and the hole (Ha) can be avoided or will not cause, if any, an especially high stress thereby to improve the durability of the drive belt. In the case of a small rocking edge distance difference, moreover, the clearance can be reduced to improve the relative positioning precision of the block.

摘要： A shift control system for shifting an automatic transmission from a predetermined gear stage to another by draining an oil pressure from predetermined frictional engagement means connected to an engine to release the same frictional engagement means and by feeding the oil pressure to another frictional engagement means to apply the same frictional engagement means while controlling the drain oil pressure of the frictional engagement means to be released and the application oil pressure of the frictional engagement means to be applied, during the shift. The shift control system comprises blowup detecting means for detecting the blown-up state of the engine being shifted in a clutch-to-clutch manner, and hydraulic control means for controlling at least one of the drain oil pressure of the frictional engagement means to be released and the application oil pressure of the frictional engagement means to be applied, on the basis of the blown-up state of the engine detected by the blowup detecting means, such that the amount of blowup of the engine may fall within a predetermined range. Since the rotation changing state of the engine being shifted is reflected upon the hydraulic control of the frictional engagement means participating in the clutch-to-clutch shift, it is possible to reliably prevent any excessive blowup of the engine and the reduction of the output shaft torque due to the tie-up of the frictional engagement means at all times.
