To enable separation of a rotary disc and a non-rotary disc in non-braking without using a disc spring.SOLUTION: A wheel type construction machine comprises: an open hole 36B positioned radially outward with respect to an outer peripheral surface of a rotary disc 35, and provided in a non-rotary disc 36 so as to penetrate in a right-left direction; a rod-like body 43 provided at a position opposite to the open hole 36B in an axis direction so as to extend in the right-left direction, and of which one end in a longitudinal direction is attached to a piston 37, and the other end projects so as to penetrate the open hole 36B; and a disc movement part 44 provided at a projection end part 43C of the rod-like body 43, and when the piston 37 is returned to an initial position by a piston return spring 41, engaged to the non-rotary disc 36 to move the non-rotary disc 36 together with the piston 37.SELECTED DRAWING: Figure 4

    【課題】 皿ばねを用いることなく、非制動時には回転ディスクと非回転ディスクとを離間できるようにする。【解決手段】 回転ディスク35の外周面よりも径方向の外側に位置して非回転ディスク36に左,右方向に貫通して設けられた貫通孔36Bと、貫通孔36Bと軸方向で互いに対面する位置に左,右方向に延びて設けられ、長さ方向の一端がピストン37に取付けられ、他端が貫通孔36Bを貫通して突出した棒状体43と、棒状体43の突出端部43Cに設けられ、ピストン戻しばね41によってピストン37が初期位置に戻されるときに、非回転ディスク36に係合してピストン37と一緒に非回転ディスク36を移動させるディスク移動部44とを備えている。【選択図】 図4
