In an upper looper holder guide 7 through which an upper looper holder 12 penetrates, a pass hole 25 opened in a spot facing 24, and a groove 26 parallel to the pass hole 25 on the outer circumference of the upper looper holder guide 7 are formed. From the pass hole 25, a first oil discharge hole 27 opened in the edge at the upper end of a through-hole 11 and a second oil discharge hole 28 opened in the groove 26 are branched off, the opening of the first oil discharge hole 27 contacts with the upper looper holder 12, and the opening of the second oil discharge hole 28 and groove 26 are exposed from a longitudinal hole 6 of an upper looper base 4 when the upper looper holder 12 reaches the top dead center or the bottom dead center. A passage hole 39 formed in a frame 2 is opened in an oil wick 29 made of felt fitted in the spot facing 24 of the upper looper holder guide 7, and is connected to a first pump body 33 of an oil discharge device composed of a two-layer trochoid pump, and oil is discharged by force byway of the first and second oil discharge holes 27, 28, while thread or cloth is not soiled due to scattering of lubricating oil above the upper looper holder by ascending or descending motion of the upper looper holder 12. <IMAGE> |
