Each of the teeth portions includes a coil winding portion, a tip end portion, and an increased width portion. The tip end portion has a circumferential width larger than a smallest width of the coil winding portion.

摘要： An easy-open end which is excellent from the standpoint of sanitation and environmental friendliness yet satisfying both the close adhesion and the scratch resistance despite of using a bisphenol A-free primer. The easy-open end has a polyester film applied, via a primer, onto the inner surface of the end of an aluminum base sheet forming a surface-treating layer that contains a zirconium compound and/or a titanium compound and an organic compound, wherein the primer contains a polyester resin that contains not less than 30% by weight of a carboxyl group-introduced polyester resin, and a phenol resin at a weight ratio of 50:50 to 85:15.

摘要： A planetary gear reducer (1) includes: a sun gear (5) having external teeth and fixed concentrically to a power input shaft (3); a plurality of planet gears (7) having external teeth and mashing with the sun gear (5); a ring gear (9) having internal teeth and meshing with the planet gears (7); a planet carrier (11) configured to support a plurality of planet shafts (13), each of which is a rotational axis of a corresponding one of the planet gears (7), and to output revolution of the plurality of planet gears (7) as first power; and a cylindrical support (27) connected to the ring gear (9) such that the cylindrical support (27) is non-rotatable relative to the ring gear (9), the cylindrical support (27) being configured to output rotation of the ring gear (9) as second power. The cylindrical support (27) includes, at its one part along the direction of a central axis, a flexible structure (41) which is curved radially inward and has a V-shaped longitudinal section. This configuration makes it possible to both obtain rigidity and prevent misalignment while suppressing an increase in the weight of the gear reducer.
