PROBLEM TO BE SOLVED: To provide a shock absorber for a tape measure capable of absorbing the impact energy when the tape is taken up and when a locking piece is moved upward by dropping a case and the like. SOLUTION: This shock absorber is composed of a receiving body 2 having a tape insertion hole 22 and receiving the locking piece 13 of a tip of the tape, a pair of arm bodies 3 for installing a bridge 31 near a falling lower end at a proper distance with respect to the receiving body 2 from the neighborhood of both ends in the tape lateral direction, of a rear upper part of the receiving body 2, and a projecting member 4 having an engagement part 5 fitted to a guide means 9 of a case 7 projected in the taking-up direction of the tape 12 from a lower part of the arm body 3. Whereby the impact energy of the locking piece 13 in taking up the tape 12 can be absorbed, and further the impact received by the locking piece 13 from its lower direction in dropping the case 7 and the like can be absorbed in a state that the locking piece 13 is locked on a tape port opening 8.
