A roller ski of an inline board type is provided to prevent an accident by limiting a turning angle range of a shaft connected to a steering part. A roller ski of an inline board type comprises a steering part(110), a connection module(120), a pair of shafts(130), and a caster part. The steering part comprises main and sub steering pipes(112,113), an erect block(115), and a fixing block(116). The erect block having a guiding hole(115b) is fixed to the bottom of the main steering pipe. The fixing block connects the main and sub steering pipes to be rotatable. The connection module has a pair of attachment blocks(121) and an extended sill(121a). The extended sill is symmetrically protruded to the direction facing to the attachment blocks. A pair of shafts becomes narrow symmetrically by the connection module. The caster part has a caster moving and advancing by the symmetrically rotating motion of the shaft.
