When installing the motor, speed reducer, and brake of the drive unit together with the sheave on the same machine base, when aligning the sheave, motor, and brake devices with a linear bearing, strict alignment is required when supporting three or more bearings. Processing is required, but by trying to adopt a two-point bearing structure, the centering problem required for the three-point bearing structure has been released, enabling easy installation and installation with reduced installation accuracy. Thus, the present invention relates to a parking apparatus that can be greatly reduced in size and lightened while having the same function.

The shaft is supported by the shafts on both sides at two locations, and the shaft joint 44a is interposed, but the shaft is strictly restrained at the output shaft mounting position on the reduction gear side, and substantially has a three-point support structure. I had to take the structure. For this reason, concentricity is required for smooth transmission of the rotational force, and accordingly, processing accuracy and mounting accuracy are strictly required, and the apparatus must be expensive. It was.

As described above, for raising and lowering a lift of a conventional parking apparatus in which two or more devices of a power transmission system shown in FIG. 5B are fixedly installed on the same base material, respectively. In the drive device D1, in order to smoothly transmit the rotational force from the drive device D1 to the sheave 42a, the motor shaft of the rotation control motor 47 installed on the same machine beam with respect to the sheave shaft installed on the machine beam In addition, a series of centering of the brake shaft of the brake device 45 is indispensable. In fact, if the structure is such that each rotating shaft is supported and installed at three points on a straight line, the processing accuracy of this centering is In addition, precision machining that ensures accurate centering requires a lot of time and money, including installation accuracy. It is cheap, lightweight and easy to assemble The emergence of highly practical drive devices and solutions therefor have been strongly desired.
