Two classes.
For example, there is the deceleration of the permanent magnet mode in being mounted in oversize vehicle disclosed in patent document 1, patent document 2
The general structure of device.
Wherein, there is the decelerator of drum-type disclosed in patent document 1.The decelerator as shown in Figure 10, revolves in drive shaft etc.
It is fixed with rotating shaft 1 as the cylindric brake drum 2 of braking element.
Then, the magnet supporting of the peripherally disposed ring-type for there are multiple permanent magnets 3 is configured with the inner side of brake drum 2
Component 4.In addition, being configured with the pole shoe 5 of ferromagnetic and above-mentioned brake drum 2 between in 3 groups of above-mentioned permanent magnet, the pole shoe 5 is configured
In the angle position essentially identical with permanent magnet 3.Above-mentioned pole shoe 5 is supported by body 6 and supports, and the supporting mass 6 makes the branch of nonmagnetic material
Bearing member 6a is between each pole shoe 5.
On the other hand, there is the decelerator of disc type disclosed in patent document 2.The decelerator is as shown in figure 11, in rotary shaft 1
On be fixed with as the discoideus brake disc 7 of braking element.
And, being configured with the mode relative with the first type surface 7a of brake disc 7 peripherally disposed has multiple permanent magnets 3

Surface 7a has vortex flow.And, using the vortex flow, produced on the brake drum or brake disc rotated together with rotary shaft
There is the brake force that direction is opposite to the direction of rotation, so that rotary shaft is slowed down.Additionally, (c) of Figure 10, (c) of Figure 11 are to represent
The figure of magnetic structure when non-brake.
However, in the case of the decelerator of drum-type and disc type, because both of which starts braking and stopping braking in switching
When the rotation of magnet supporting member need power needed for larger work, therefore driver to become big and be difficult to be carried to automobile.
Therefore, propose to have in patent document 3 to reduce magnet supporting member when switching starts braking and stops braking
Rotation needed for work needed for decelerator for the purpose of power.
Decelerator proposed in patent document 3 is provided with outer in the mode for making respective permanent magnet relative from brake drum side

To make magnetic pole towards circumferencial direction, and magnetic pole relative in a circumferential direction is homopolarity.On the other hand, in the magnet ring of inner side,
Multiple permanent magnets are configured to make magnetic pole towards diametric(al), and the alternating polarity of magnetic pole adjacent in a circumferential direction is opposite.And
And, in outside, the inner peripheral surface of magnet ring is formed with makes the two ends of the circumferencial direction along the extension of above-mentioned permanent magnet extend from permanent magnet
Recess, and in the position at the two ends of recess, to avoid permanent magnet in the way of be formed with further deep-cut outer magnet ring and
Into deep-cut portion.
In the case of decelerator proposed in the patent document 3, inner side when switching starts braking and stops braking
Power needed for work needed for the rotation of magnet ring diminishes.However, the structure there are, part number of packages increases, manufacture funds increase this
The problem of sample.
Therefore, applicant proposed the decelerator (patent document 4) for constituting as follows：By to piston compression area compared with
Big side supplies air and makes piston rod prominent to the direction of rotation of brake drum, so as to carry out switching to startup from stopping braking
The rotation of magnet supporting member during braking.
In the case of the decelerator that patent document 4 is proposed, because part number of packages is constant, therefore manufacture will not be produced to pass through
Take the such problem of increase.If however, be intended to further to seek the overall cost degradation of device and miniaturization, in patent document 4
In the decelerator for being proposed, the power of cylinder is not enough.On the other hand, according to the cylinder of the push-pull effort for meeting regulation, then cannot seek
