PURPOSE: A rake in which rake ribs are attached and detached one by one is provided to include rake ribs which are comprised of an elastic metal fine width tape, be flexible because the rake ribs have good flexural elasticity, and enable an easy detachment in case the rake ribs which are formed in a front end part are caught at an obstacle. CONSTITUTION: A rake in which rake ribs are attached and detached one by one comprises a rake main body (1), rake ribs (3), and a rake handle (5). The rake main body forms a reinforce projection line (1c) in a radial shape between projections by forming projection lines (1a,1b) of arc side by side, is equipped with a reinforcement part fixing groove and a winding part insertion groove (1f) in a front end part and a central part, and includes a rake handle insertion pipe (1h) in which a rake handle insertion part is formed from a rear end into the main body. The rake rib is inserted into the rake rib fixing groove of the rake main body, is comprised of an elastic metal, uses a material of a fine width band shape of width 3-6 mm and thickness 0.7-1.5 mm, and forms an insertion part in the rear end part. The insertion part is divided in the inner side in a longitudinal direction, cut an inner side end of a division line at a right angle about a longitudinal direction, bends a cutting part downwards, and forms an elastic protrusion. The rake handle is comprised of a metal rod of diameter 3-6 mm, is bent in a V shape, is equipped with a coupling piece (4b) in which both sides of a bent part (4a) are combined with the outside of the rake handle insertion pipe. A coupling projection is formed in a front end part of both supporting arms in order to be inserted into the reinforcement part fixing groove of the rake main body. 'A reinforcement part and the front end part which are combined with the upper side of the rake main body' are inserted into the handle insertion pipe of the rake main body and are fixed with a coupling piece by forming a winding part (4d) in the center.
