Abstract:
The present invention addresses the problem of providing a speed reducer having excellent characteristics of absorbing an impact force. This speed reducer is characterized by comprising: a worm (25) to which the rotating shaft of a motor (22) is connected; an output gear (26) meshing directly, or through an intermediate gear, with the worm (25); a power transmission body (35) having a base (36, 39) having an engagement hole formed at the center thereof, the power transmission body (35) also having a plurality of spring pieces (41) which are provided along the outer periphery of the base (36, 39) and which serve as dampers, the spring pieces (41) being formed by bending band-shaped bodies so that crests and troughs are continuously alternated, the power transmission body (35) further having a fitting section (42) which is one of the troughs of the spring pieces (41) and into which a protrusion (31) of the output gear (26) fits, the entire power transmission body (35) being formed integrally from a synthetic resin, the power transmission body (35) being configured so that the protrusion (31) of the output gear (26) fits into the fitting section (42), allowing the power transmission body (35) to be received into a recess (30) in the output gear (26); and an output shaft (28) engaging with the engagement hole (37) in the base (36) of the power transmission body (35).
