A detent of a rail turnout is provided to manufacture easily, to have high structural efficiency, to secure stable bearing capacity with precision construction and to be advantageous to linear maintenance between rails at maintenance. The detent(1) of a rail turnout contains a rectangular bolt insertion hole(12) formed at the center, a contact plate(13) projected forward from the top of a fixing portion(11) formed vertically to be inserted to a neck of a fixing rail, a stiffening piece(14) formed between two side walls of the fixing portion and two lower sides of the contact plate to increase the binding strength, a pair of support projections(16) projected vertically to have small contact area when fixing to the fixing rail with a bolt and a nut, and stress concentration parts(18) projected to two upper sides of the contact plate by forming a projection(15) to be higher than the contact plate and a retreated groove(17) to extend from the boundary of the projection to the upper center of the contact plate to concentrate pressure added upward through a shear portion of the contact plate to prevent the contact plate from being bent upward or damaged. |
