- a hydraulic shock absorber in which an electromagnetic coil is incorporated in a part thereof is disclosed in Japanese Patent Application Laid-Open No. Hei 5-44478. This is achieved by mounting a coil on the cylinder of the hydraulic shock absorber and a magnet on the piston rod, and energizing the coil to generate a driving force (electromagnetic force) along the stroke direction of the biston rod. It is intended to control the amount of expansion and contraction of the suspension device according to the traveling state of the vehicle.
- a device in which an electromagnetic coil or the like is incorporated in this hydraulic shock absorber requires a hydraulic pressure, a power supply, and the like, which complicates the structure and is disadvantageous in cost.
- This electromagnetic shock absorber is basically configured, for example, as shown in the model of FIG.
- the resistance depends on the electromagnetic force generated at that time. It attenuates the movement.
- the motor 50 is supported by a support frame 60, and a movable frame 40 that is guided to slide freely with respect to the support frame 60 is provided.
- a movable frame 40 that is guided to slide freely with respect to the support frame 60 is provided.
- the ball nut 47 is attached to the moving frame 40, and the screw shaft 46 screwed with the ball nut 47 is the motor 50.
- the support frame 60 has upper and lower brackets 61 and 62 and an intermediate bracket 63 positioned between the upper and lower brackets 61 and 62.
- the screw shaft 46 is rotatably supported through a bearing 65 provided on the intermediate bracket 63.
- the moving frame 40 has upper and lower brackets 41 and 42 and a plurality of guide rods 43 connecting these brackets.
- Guide rod 4 of moving frame 40 3 Force The lower bracket 32 of the supporting frame 30 is slidably penetrated, thereby guiding the moving frame 40 to slide parallel to the screw shaft 46. .
- the ball nut 47 is attached to an upper bracket 41. Inside the pole nut 47, although not shown, a number of poles are arranged along a screw groove, and the screw shaft is attached to the pole nut 47. Reference numeral 46 is screwed through the plurality of balls.
- this electromagnetic shock absorber When this electromagnetic shock absorber is used, for example, as a vehicle suspension by being interposed between a vehicle body and an axle, the mounting bracket 6 of the support frame 60 above the motor 50 at the upper end of the electromagnetic shock absorber. 6 is connected to the vehicle body side, and the mounting eye 44 provided on the lower bracket 42 of the moving frame 40 at the lower end of the electromagnetic shock absorber is connected to the axle side.
- the pole nut 47 moves linearly in the direction of the arrow X together with the moving frame 40, the ball arranged along the screw groove in the pole nut 47 and the screw shaft By screwing with the screw groove of 46, the screw shaft 46 rotates at that position.
- the rotational motion of the screw shaft 46 is transmitted as a rotational motion in the direction of the arrow Y of the rotary shaft 51 via a cutting 55 attached to the upper end of the screw shaft 46, thereby rotating the motor 50. .
- a permanent magnet is provided on the rotor, and the coils of the respective magnetic poles of the stator are directly short-circuited to each other or connected via a control circuit so as to obtain a desired electromagnetic force.
- the electromagnetic force generated by the current becomes a torque that opposes the rotation of the rotating shaft 51 of the motor 50.
- the magnitude of the torque depending on the electromagnetic force opposing the rotation direction of the rotating shaft 51 can be freely changed by changing the magnitude of the resistance in the control circuit connected to the coil.
- the electromagnetic torque that becomes a resistance to the rotation of the rotating shaft 51 suppresses the rotation of the screw shaft 46.
- This torque is a resistive force that suppresses the linear movement of the pole nut 47 of the pole screw mechanism 45. That is, it acts as a damping force for the vibration input to the electromagnetic shock absorber.
- the monitor 50, screw shaft 46, and pole nut 47 are exposed, they are not isolated at all from intrusion of rain or mud from outside the vehicle body. For example, rainwater or muddy water may enter the motor 50, causing the motor 50 to leak and be damaged, thereby impairing the functions of the motor 50 and the like.
- the outer diameter is increased by that much due to the cover arranged outside the motor 50.

A sufficient gap cannot be provided between the outer case portion and the force par covering the outer case portion, and the heat radiation of the motor 50 against heat generation deteriorates.
- the motor 50 is rotated by the expansion and contraction of the shock absorber while the vehicle is running. At that time, heat is always generated by the current flowing through the coil. If the heat radiation is poor, the motor itself will rise in temperature. If the temperature of the motor 50 rises and exceeds the temperature rating of the motor 50, the insulation properties of the insulation coating of the conductor forming the coil will deteriorate due to chemical changes due to heat, etc. This may cause damage to the motor itself.
- An object of the present invention is to promote heat dissipation of a motor and prevent damage due to a temperature rise exceeding the rating of the motor.

Then, the frame of the motor is formed, and the outer cylinder constitutes the tubular member.
