Abstract
A distributor for an internal combustion engine comprising a rotational signal generator (4) which includes a rotary magnetic shield (30) for generating an electrical signal indicative of the shaft rotational speed. The rotary magnetic shield (30) comprises a rotor plate (31) attached at the center thereof to the rotary shaft and a plurality of shield tabs (37) disposed around the plate and extending perpendicularly thereto. The rotor plate (31) and each shield tab (37) are integrally connected by a transition portion (33) including a round bend (36) for moderating stress concentration. The transition portion (33) also has integral fillets (35) defining a peripheral edge smoothly connecting the edge of the main plate (31) and side edges of the shield tabs (37) for moderating concentration of stress at edges of the transition portions (33). The fillets (35) of two adjacent transition portions (33) may define a continuously curved edge in a plane of the main plate (31).
