In a chain wheel with pockets (3) for locating horizontal links (4) of a round steel chain, teeth (2) are used, adjoining the rounded tooth-root sections (6) of which are inclined surfaces (7) which serve to support horizontal links (4) of chains, the picth of which is larger than the pitch of the chain wheel. A conventional support of the horizontal links on flat bottoms (8) of the pockets (3) is deliberately omitted.
