An automatic transmission comprises a multi-plate brake 70 to brake a specified rotational element of a transmission mechanism, which includes a plurality of frictional plates 71, 71b, a piston 72, a piston cylinder member 73 comprising cylinder in which the piston slides, and oil-pressure chambers 75a, 75b which are formed between the piston and the cylinder and bias the piston 72 toward the frictional plates with an oil pressure supplied thereto, and a valve body 200 to supply the oil pressure to the oil-pressure chambers 75a, 75b. Herein, the valve body 200 is provided in the vicinity of an outer periphery of the piston cylinder member 73 so as to be connected to the piston cylinder member via a connection portion, and there is provided an oil passage to supply the oil pressure from the valve body 200 to the oil-pressure chambers 75a, 75b via the connection portion.

An oil-pressure output device (electric pump unit 21 ) is arranged on an outer wall face of an automatic transmission 1 which is positioned on an opposite side to an engine 2 (left side of a vehicle). An arrangement position of the oil-pressure output device is out of a movable range of one of the steered driving wheels which is located on the opposite side to the engine (left front wheel 17 ). Accordingly, a simpler layout change between a case of attaching the oil-pressure output device to the automatic transmission and another case of not attaching the one can be provided, so that commonality of components or layout of the automatic transmission and its surrounding devices and structures can be provided.

A cylinder block (3) for a multi-cylinder engine (1) is provided with a water jacket (w) partly on an intake side of a row of cylinders (s1 - s4) and partly on an exhaust side of the row of cylinders (s1 - s4) and a water guide passage (71) through which cooling water is introduced into the water jacket (w). The cylinder block is provided with oil return passages each of which extends straight from top to bottom of the cylinder block (3) between each adjacent cylinders. A branch oil return passage (90) branches off from a middle portion of the rearmost oil return passage (86, 87) and extends rearward up. A generally triangular director pillar (73) having a bolt hole (37), that is defined by first to third side walls (73a, 73b, 73c), is disposed with the first side wall (73a) adjacent to a foremost cylinder (s1) placed approximately perpendicularly to a line (L) passing center axes of the foremost cylinder (s1) and the bolt hole (37), an edge line (73d) facing the first wall (73a) placed in an interface between the water jacket (w) and the water guide passage (71) and the second and third side walls (73b, 73c) placed so as to direct a cooling water stream partly to the water jacket on the intake side and partly to the water jacket on the exhaust side, respectively.
