PURPOSE:To provide a grip having excellent initial gripping feeling, excellent long-term stability, and weather resistance. CONSTITUTION:Olefinic thermoplastic resin in the continuous phase and vulcanized rubber in the discontinuous phase are blended to form a dynamic vulcanized rubber, the measured value of the hardness of the dynamic vulcanized rubber measured by a JIS K6301 spring type hardness tester A is in the range of 40-70 immediately after the contact with the measured surface of the dynamic vulcanized rubber, and the reduction of the measured value 30 sec after the contact is 5 or below. |
