A tool magazine having a plurality of grips for gripping tool holders for use in a machine tool. The tool holder gripped at the grip is transferred to a holder portion of a spindle of a machine tool, or the tool holder held in the holder portion is transferred to the grip. The magazine has a magazine disk rotatable about a horizontal axis for tool indexing operation. The tool holder extends in the horizontal direction when it is gripped by the grip, and the spindle also extends in the horizontal direction. Each grip includes a pair of first and second arm members pivotally supported on the magazine disk and extending in a radial direction of the magazine disk. The first and second arm members has tool gripping portions movable toward and away from each other for gripping and releasing the tool holder. A compression spring is provided between the pair of first and second arm members for normally urging the first and second arm members to their tool gripping positions. First and second gear portions are provided in meshing relation to the first and second arm members, respectively. If lower side arm member is moved by the weight of the tool holder, the upper side arm member is moved interlockingly and symmetrically to compress the compression spring.
