Disclosed is a poppet block assembly of a transmission unit. According to an embodiment of the present invention, the poppet block assembly of a transmission unit is a poppet block mounted on a front end of a control shaft and has a shift ball positioned to be in close contact with the upper part of the poppet block. The poppet block comprises a first groove part, a second groove part, third groove parts, and a protrusion part. The first groove part is formed on the center of an upper surface of a poppet body to have a concave shape formed in a longitudinal direction and is extended in the longitudinal direction. The second groove part is arranged with a symmetrical shape with respect to left and right sides of the upper surface of the poppet body, protrudes from the first groove part to be rounded with a predetermined radius of curvature, and is extended along the poppet body to the outside while having a convex shape. The third groove parts are extended from both of the right and left ends of the second groove part in a radius direction while having a convex shape and have ends extended upward. The protrusion part has one to n of unit protruding pieces formed on the upper surface of the poppet body in such a manner that the unit protruding pieces are spaced from each other at predetermined intervals and protrude from the upper parts of the first groove part, the second groove part and the third groove parts. |
