    摘要： The disclosed is a deceleration device including a cylindrical brake member (1) fixed to a rotary shaft, a plurality of permanent magnets (3) arrayed in a circumferential direction of a circle around the rotary shaft, a cylindrical magnet holder (2) holding the permanent magnets, and a switching mechanism that switches between a braking state and a non-braking state. The plurality of permanent magnets include primary magnets (3A) and secondary magnets (3B) that are arrayed alternatively in the circumferential direction. The primary magnets (3A) are laid such that magnetic poles of each of the primary magnets (3A) are arranged in a radial direction from an axis of the rotary shaft and such that two circumferentially adjacent ones of the primary magnets (3A) have opposite magnetic pole arrangements. The secondary magnets (3B) are laid such that magnetic poles of each of the secondary magnets (3B) are arranged in the circumferential direction. When viewed on a surface facing the brake member (1), north poles of the primary magnets (3A) are circumferentially adjacent to and in contact with north poles of the secondary magnets (3B), and south poles of the primary magnets (3A) are circumferentially adjacent to and in contact with south poles of the secondary magnets (3B). The magnetic holder (2) is ferromagnetic.

    摘要： Since a speed reducer includes: a brake disk that is fixed to a rotationl shaft of a vehicle; permanent magnets that are disposed not only oppositely relative to a principal surface of the brake disk but also circumferentially in such a manner that each magnet is magnetized in reverse polarity to adjacent ones; a rotational member that retains the permanent magnets, has a switch brake disk, and is rotatably supported by the rotational shaft; a switch brake caliper that has brake pads sandwiching the switch brake disk therebetween, and is fixed to an irrotaional portion of the vehicle; and an electric linear actuator of a planetary roller mechanism that causes the brake pads to be linearly driven by converting rotational motion of the electric motor into linear motion, the speed reducer can realize a reduction in size, and thus can be installed even in a small- to mid-size vehicle not especially equipped with a compressed air tank or the like.
