A lockup device1is disposed inside a fluid chamber between a front cover3and a turbine4and provided with a clutch-purpose friction plate12, a pair of drive the plates13and14, a driven plate15, and coil springs16. The friction plate12can be coupled with the front cover3. An extended part18extends from one of the plates13and14toward the other and engages with the inside circumferential edge of the friction plate12such that the friction plate cannot rotate but can move in the axial direction relative to the extended part. The driven plate15is fixed to the turbine4. The coil springs16are compressed between pair of drive the plates13and14and the driven plate15when the pair of drive plates and the driven plate rotate relative to each other.

A frame type tractor as defined in claim 9, wherein said first reinforcing cross unit and said second reinforcing cross unit are formed of cast material.12. A frame type tractor as defined in claim 9, wherein said elongate members are elongate plates.13. A frame type tractor comprising: a main frame extending longitudinally of a tractor body; an engine mounted in a front region of said main frame; a transmission case mounted in a rear region of said main frame; a backhoe mounting frame attached to a rear end of said main frame; and rollover protection system mounts arranged in upper portions of said backhoe mounting frame for fixedly supporting a rollover protection system, wherein said main frame includes a pair of right and left elongate members, said main frame being reinforced by a sub-frame including sub-elongate members arranged laterally outwardly of said elongate members, mower suspending mechanisms for suspending a mower unit each being arranged between one of said right and left elongate members and one of said sub-elongate members. 14. A frame type tractor as defined in claim 13, wherein: said backhoe mounting frame has a frame structure defining an inner space therein and including a pair of right and left side walls, a top wall interconnecting upper ends of said side walls, and a bottom wall interconnecting lower ends of said side walls; and said right and left side walls have said rollover protection system mounts and backhoe attaching portions for engaging and connecting a backhoe unit. 15. A frame type tractor as defined in claim 14, wherein said backhoe mounting frame includes a top link mount for attaching a top link of a three-point link mechanism, and lower link mounts for attaching lower links of the three-point link mechanism, at least part of said transmission case being fitted in said inner space of said backhoe mounting frame.16. A frame type tractor as defined in claim 13, further comprising a connector for interconnecting said rollover protection system mounts.17. A frame type tractor as defined in claim 13, further comprising rear wheels arranged laterally of said transmission case, said rear wheels, said backhoe mounting frame and said rollover protection system being arranged substantially in one vertical plane.18. A frame type tractor as defined in claim 13, further comprising frame reinforcing units for connecting upper portions of said backhoe mounting frame to portions of said main frame remote from said backhoe mounting frame.19. A frame type tractor as defined in claim 18, wherein said main frame includes a pair of right and left elongate members, and a cross member interconnecting said elongate members, said frame reinforcing units being connected also to said cross member.20. A frame type tractor comprising: a main frame extending longitudinally of a tractor body; an engine mounted in a front region of said main frame; a transmission case mounted in a rear region of said main frame; and a backhoe mounting frame attached to a rear end of said main frame, wherein said main frame includes a pair of right and left elongate members, at least one cross member interconnecting said elongate members, and a first reinforcing cross unit and a second reinforcing cross unit interconnecting said elongate members forwardly and rearwardly of said transmission case, and each of said first reinforcing cross unit and said second reinforcing cross unit includes two substantially L-shaped split members respectively having vertical portions and horizontal portions, said horizontal portions being connectable to and disconnectable from each other, said vertical portions being connectable to and disconnectab
