Claim:
1. A tilting pad type journal bearing comprising: a plurality of pads which are arranged along the periphery of a rotary shaft; a bearing housing which supports the pads in a tiltable manner via a plurality of pivots; and a plurality of nozzles which are each disposed between the pads to supply lubricating oil to sliding surfaces of the pads, wherein the sliding surface of each of the pads is formed so that a width of the sliding surface increases 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 includes a groove part having a trapezoidal shape when viewed in the normal direction with respect to a top surface of the tip end part, which induces a flow heading from lateral parts towards a center in the width direction, in an oil flow from the rear edge part of the sliding surface of an upstream pad to the front edge part of the sliding surface of a downstream pad.
