Abstract: To provide a quite novel automotive vehicle floor mat and an automotive vehicle floor mat retainer unit, in which retainer pins and retainer holes are provided at two positions to make it possible to positively perform the positioning upon laying the mat, and in addition, the positions and the arrangement interval of these retainer pins and the retainer holes are suitably selected to thereby dispense with using a structure for adjusting the interval between the retainer pins, also to cope with change of the hole positions due to the aging change, to make it possible to use the mat for a long period of time without a fear that the retainer pins could not be fitted into the retainer holes, to narrow the interval not too much to thereby make it possible to perform the positive positioning upon laying the mat, i.e.
