DEVICE FOR CONNECTING TWO MEMBERS
A pin side engaging member (43) is provided at an end portion (26A) of a left connecting pin (26), and a bracket side engaging member (44) having a recessed groove portion (44B) is provided on a left boom bracket (22). Meanwhile, a pin side engaging member (46) is provided at an end portion (27A) of a right connecting pin (27), and a bracket side engaging member (47) having a recessed groove portion (47B) is provided on a right boom bracket (23) . The pin side engaging member (43) is inserted into the recessed groove portion (44B) in a state in which the left boom bracket (22) and a left boom foot portion (24) are connected by the left connecting pin (26), and the pin side engaging member (46) is inserted into the recessed groove portion (47B) in a state in which the right boom bracket (23) and a right boom foot portion (25) are connected by the right connecting pin (27). In consequence, the left and right connecting pins (26) and (27) can be restricted from rotating with respect to the left and right boom brackets (22) and (23).
