Summary:In the conventional connection and fixture part between a working vehicle and an excavator, a connection pin is made to contact a guide plate to be fixed in position, thereby requiring a high rigidity of the guide plate, accuracy of recreation of positioning of the connection pin, and high cost for manufacturing the guide plate. Thus, guide plate 26 of connection portion 23 has a chevron-shaped introduction part including two sector curves. A U-shaped bent member serving as a knob 33 is provided on a rear side surface of a connection pin 32 in the axial direction of connection pin 32, so that the proper position of the inserted connection pin is defined as the position thereof when tips of knob 33 come to contact the insertion-target member.
