<P>PROBLEM TO BE SOLVED: To provide an attachment mounting device that can be shared among different models. <P>SOLUTION: An attachment mounting device is provided in which a pinion 403 is attached to an output shaft of a lock pin motor 402 and engaged with a pair of horizontal racks 404U and 404L. The racks 404U and 404L each are smoothly guided in a horizontal direction by a guide 405 provided near the pinion 403 and supported in the radial direction of the pinion 403. This allows the driving force of the pinion 403 to be transmitted to the racks 404U and 404L with reliability. A lock pin 407P extends to pass through plates 112R, 113R, 112L, and 113L and is provided at the end of each of racks 404U and 404L. The lock pin 407P is moved forward and backward with respect to a bucket connecting portion 320 by racks 404U and 404L sliding in a horizontal direction, thereby allowing a bucket 112 to be attached to and detached from the attachment mounting device 300. <P>COPYRIGHT: (C)2013,JPO&INPIT |
