A tilting pad type journal bearing comprising: a plurality of pads (2; 2A) which are arranged along the periphery of a rotary shaft; a bearing housing which supports the pads (2; 2A) in a tiltable manner via a plurality of pivots; and a plurality of nozzles (5; 31) which are each arranged between the pads (2; 2A) to supply lubricating oil to sliding surfaces of the pads (2; 2A), characterized in that: the sliding surface of each of the pads (2; 2A) is formed so that the width of the sliding surface increases as it goes from a front edge part towards a rear edge part of the sliding surface, and a tip end part of at least one of the nozzles has a groove part formed on a top surface of the tip end part and the groove part has a trapezoidal shape when viewed in the direction of the normal to the top surface, wherein the width dimension of the front edge of the groove part is equal to the width dimension of the rear edge of the sliding surface of the pad, and the width dimension of the rear edge of the groove part is equal to the width dimension of the front edge of sliding surface of the pad, thereby inducing a flow heading from lateral parts towards the center in the width direction, in an oil flow from the rear edge part of the sliding surface of an upstream pad (2; 2A) to the front edge part of the sliding surface of a downstream pad (2; 2A). a plurality of pads (2; 2A) which are arranged along the periphery of a rotary shaft; a bearing housing which supports the pads (2; 2A) in a tiltable manner via a plurality of pivots; and a plurality of nozzles (5; 31) which are each arranged between the pads (2; 2A) to supply lubricating oil to sliding surfaces of the pads (2; 2A), characterized in that: the sliding surface of each of the pads (2; 2A) is formed so that the width of the sliding surface increases as it goes from a front edge part towards a rear edge part of the sliding surface, and a tip end part of at least one of the nozzles has a groove part formed on a top surface of the tip end part and the groove part has a trapezoidal shape when viewed in the direction of the normal to the top surface, wherein the width dimension of the front edge of the groove part is equal to the width dimension of the rear edge of the sliding surface of the pad, and the width dimension of the rear edge of the groove part is equal to the width dimension of the front edge of sliding surface of the pad, thereby inducing a flow heading from lateral parts towards the center in the width direction, in an oil flow from the rear edge part of the sliding surface of an upstream pad (2; 2A) to the front edge part of the sliding surface of a downstream pad (2; 2A). the sliding surface of each of the pads (2; 2A) is formed so that the width of the sliding surface increases as it goes from a front edge part towards a rear edge part of the sliding surface, and a tip end part of at least one of the nozzles has a groove part formed on a top surface of the tip end part and the groove part has a trapezoidal shape when viewed in the direction of the normal to the top surface, wherein the width dimension of the front edge of the groove part is equal to the width dimension of the rear edge of the sliding surface of the pad, and the width dimension of the rear edge of the groove part is equal to the width dimension of the front edge of sliding surface of the pad, thereby inducing a flow heading from lateral parts towards the center in the width direction, in an oil flow from the rear edge part of the sliding surface of an upstream pad (2; 2A) to the front edge part of the sliding surface of a downstream pad (2; 2A).
