PROBLEM TO BE SOLVED: To provide a compact vehicle transmission device including a compact check valve and ensuring sealing between a case member and the check valve. SOLUTION: A hole part 4A of a transmission case 4 includes: an inner circumferential face 4b with a female screw 4d formed thereon; and a bottom part 4c having a hole part 4e communicating with an oil passage 4a and an outer edge part 4f surrounding the hole part 4e. A check valve case 11 of a check valve 10 includes: a cylindrical part 11a housing a stop mechanism 15 therein and having a male screw 11c formed on an outer face thereof and screwed into the female screw 4d; and a contact face 11d formed on a tip end 11b of the cylindrical part 11a and to be brought into contact with the outer edge part 4f. When the check valve 10 is screwed into the hole part 4A of the transmission case 4, the outer edge part 4f is brought into tight contact with the contact face 11d to achieve sealing between the oil passage 4a and an oil passage 6a.
