Abstract: A soundproof cover which covers a target object is provided with: a sound absorbing sheet which is formed in a planar shape by means of a sound absorbing material and which covers the surface of the target object; and a reinforcing member which is disposed in a position engaging with engaged portions of the target object, and which positions the sound absorbing sheet with respect to the target object with at least a portion of the sound absorbing sheet exposed. The reinforcing member is provided with: a first reinforcing portion, which is an elongate member and which is disposed in a position engaging with a first engaged portion of the target object; and second reinforcing portions, which are elongate members and which are disposed in different positions to the first reinforcing portion.

Abstract: A sound-absorbing cover comprises a first sound-absorbing layer and a second sound-absorbing layer made of foam, a first skin layer of the first sound-absorbing layer and a second skin layer of the second sound-absorbing layer are layered in a state of being made to face each other, and an air layer is provided between the facing surfaces of the first skin layer and the second skin layer. The rigidity of the first skin layer of the first sound-absorbing layer is different from the rigidity of the second skin layer of the second sound-absorbing layer.

Abstract: An AC generator for vehicles includes a rotor, a stator, a frame, a bearing retaining portion, and a resin-made cylindrical member. The bearing retaining portion is disposed in the frame, and retains a bearing that rotatably supports the rotor. The resin-made cylindrical member is disposed between the bearing and the bearing retaining portion, and an inner circumferential surface thereof has a simple cylindrical shape while an outer circumferential surface thereof has a thick portion in a part thereof.

Abstract: A stator 3 of an on-vehicle AC generator 1 denoting a dynamo-electric machine has a stator core 32 having slots 35 arranged in a line along a circumferential direction of the stator core 32, electric conductors which are inserted into the slots 35 to be protruded from an end surface of the stator core 32 in an axial direction of the stator core 32 and of which portions protruded from an end surface of the stator core 32 in an axial direction of the stator core 32 are bent in the circumferential direction, and an electric insulating member 34 which is arranged between an inner wall of each slot 35 of the stator core 32 and a peripheral surface of the electric conductor so as to surround the electric conductor and has at least two duplicate layers 34A and 34B formed by duplicating the electric insulating member 34.
